GENERAL SAFETY RULES
WORK AREA SAFETY
1. Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of flammable liquids,
gases or dust. Power tools create sparks which may ig-
nite the dust or fumes.
3. Keep children and bystanders away while operating
a power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
1. Power tool plugs must match the outlet. Never mod-
ify the plug in any way. Do not use any adapter plugs
with earthed (grounded) power tools. Unmodified plugs
and matching outlets will reduce risk of electric shock.
2. Avoid body contact with earthed or grounded surfac-
es such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body
is earthed or grounded.
3. Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of elec-
tric shock.
4. Do not abuse the cord. Never use the cord for car-
rying, pulling or unplugging the power tool. Keep cord
away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric
shock.
5. When operating a power tool outdoors, use an ex-
tension cord suitable for outdoor use. Use of a cord
suitable for outdoor use reduces the risk of electric
shock.
6. If operating a power tool in a damp location is un-
avoidable, use a ground fault circuit interrupter (GFCI)
protected supply. Use of a GFCI reduces the risk of elec-
tric shock.
PERSONAL SAFETY
1. Stay alert, watch what you are doing and use com-
mon sense when operating a power tool. Do not use a
power tool while you are tired or under the influence
of drugs, alcohol or medication. A moment of inatten-
tion while operating power tools may result in serious
personal injury.
2. Use personal protective equipment. Always wear
eye protection. Protective equipment such as a respira-
tory mask, non-skid safety shoes and hearing protection
used for appropriate conditions will reduce the risk of
personal injury.
3. Prevent unintentional starting. Ensure the switch is
in the off-position before connecting to power source
and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or
energizing power tools that have the switch on invites
accidents.
4. Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to a
rotating part of the power tool may result in personal
injury.
5. Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or jew-
elry. Keep your hair and clothing away from moving
parts. Loose clothes, jewelry or long hair can be caught
in moving parts.
Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool”
in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE SAFETY INSTRUCTIONS.
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may
result in electric shock, fire and/or serious injury.

GENERAL SAFETY RULES
7. If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection
can reduce dust-related hazards.
POWER TOOL USE AND CARE
1. Do not force the power tool. Use the correct power
tool for your application. The correct power tool will
do the job better and safer at the rate for which it was
designed.
2. Do not use the power tool if the switch does not turn
it on and off. Any power tool that cannot be controlled
with the switch is dangerous and must be repaired.
3. Disconnect the plug from the power source and/or
the battery pack from the power tool before making
any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
4. Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the power
tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained us-
ers.
5. Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool’s opera-
tion. If damaged, have the power tool repaired before
use. Many accidents are caused by poorly maintained
power tools.
6. Keep cutting tools sharp and clean. Properly main-
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
7. Use the power tool, accessories and tool bits, etc.
in accordance with these instructions, taking into ac-
count the working conditions and the work to be per-
formed. Use of the power tool for operations different
from those intended could result in a hazardous situa-
tion.
8. Use clamps to secure your workpiece to a stable
surface. Holding a workpiece by hand or using your
body to support it may lead to loss of control.
9. KEEP GUARDS IN PLACE and in working order.
SERVICE
1. Have your power tool serviced by a qualified repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is main-
tained.
CALIFORNIA PROPOSITION 65 WARNING

drilling, and other construction activities may contain
chemicals, including lead, known to the State of Califor-
nia to cause cancer, birth defects, or other reproductive
harm. Wash hands after handling. Some examples of
these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement, and other
masonry products.
• Arsenic and chromium from chemically treated
lumber.
Your risk from these exposures varies depending on
how often you do this type of work. To reduce your ex-
posure to these chemicals, work in a well-ventilated area
with approved safety equipment such as dust masks
specially designed to filter out microscopic particles.

MINI CHAINSAW SAFETY WARNINGS
WARNING! Do not operate the power tool until you have read and understood the following instructions and
the warning labels.
MINI CHAINSAW SAFETY
1. TOOL PURPOSE. This chainsaw is designed for saw-
ing wood. Sawing other types of materials may result
in serious injuries, machine damage and voiding of the
warranty.
2. Keep all parts of the body away from the saw chain
when the chainsaw is operating. Before you start the
chainsaw, make sure the saw chain is not contacting
anything. A moment of inattention while operating the
chain saw may cause entanglement of your clothing or
body with the saw chain.
3. Always hold the mini chainsaw with your dominant
hand. Maintain control.
4. Only hold the power tool by the insulated gripping
surfaces to avoid electric shock in case the saw chain
contacts hidden wiring. Saw chains contacting a live
wire may make exposed metal parts of the power tool
live and can give the operator an electric shock.
5. Wear safety glasses and hearing protection. Pro-
tective equipment for hands, legs, head and feet is also
highly recommended. Protective clothing greatly reduc-
es the risk of personal injury from loose debris or ac-
cidental contact with the saw chain.
6. Do not operate the chainsaw while standing in a
tree. Only operate the chainsaw from a firm, level sur-
face fixed on the ground.
7. Always keep proper footing during operation. Slip-
pery or unstable surfaces such as ladders may cause a
loss of balance or control.
8. When cutting a limb that is under tension, be alert
for spring back. When tension from wood fibers and
branches is suddenly released, the limb may fly in un-
predictable ways, possibly resulting in kickback and in-
jury to the user.
9. Use extreme caution when cutting brush and sap-
lings. The slender material may catch the saw chain,
whipping towards you or pulling you off balance.
10. Carry the chainsaw by the handle with the chain-
saw switched off, the battery disconnected, and the
chain away from your body. When transporting or stor-
ing the chainsaw, always protect the blade with a scab-
bard (blade cover).
11. Routinely lubricate, adjust chain tension, and
check chain for dullness. Follow these instructions
closely to minimize kickback and maximize the lifespan
of the tool.
12. Keep handles dry, clean and free of oil and grease.
Slippery handles increase the chances of losing control.
13. Before beginning each day, check the chain guard
for proper operation. It should spring back over the bar
and chain, but not contact the chain. If the guard does
not operate properly, do not operate the chainsaw until
the chain guard is repaired.
14. Do not disable the chain guard. Doing so significant-
ly increases the risk of injury.
15. Only use this chainsaw to cut wood. Do not cut plas-
tic, masonry, or other non-wood materials. Do not use
this chainsaw for anything other than its intended pur-
pose. Let the saw work at its own pace.
7
MINI CHAINSAW SAFETY WARNINGS
REDUCING KICKBACK
Kickback can occur when the tip of the guide bar touches
an object or when the wood closes in and pinches the
saw chain inside of the cut. Tip contact can kick the guide
bar up and back towards the operator. Pinching the saw
chain along the top of the guide bar can push the bar
rapidly towards the operator. Either of these reactions
may cause a loss in control of the pole saw, increasing
the chances of serious personal injury. Do not rely on the
safety devices built into the saw. Pole saw users should
take as many precautions as possible to minimize on-
site accidents. Kickback is the result of tool misuse and/
or incorrect operating procedures. These conditions can
be minimized with the following steps:
1. Maintain a firm grip, with thumbs and fingers en-
circling the pole saw handle. Both hands should be on
the saw with your body and arms in a position to resist
kickback forces. Kickback forces can be controlled by
the operator, if proper precautions are taken. Do not let
go of the pole saw.
2. Maintain a firm grip, with thumbs and fingers encir-
cling the mini chainsaw handle. Keep your body and
arms in a position to resist kickback forces. Kickback
forces can be controlled by the operator, if proper pre-
cautions are taken. Do not let go of the mini chainsaw.
3. Do not overreach and do not cut above shoulder
height. This helps prevent unintended tip contact and
enables better control of the pole saw in unexpected
situations.
4. Only use replacement bars and chains specified by
WEN. Incorrect replacement bars and chains may cause
chain breakage and/or kickback.
5. Follow the manufacturer’s sharpening and main-
tenance instructions for the pole saw. Decreasing the
depth gauge height can lead to increased kickback.
WARNING! Do not operate the power tool until you have read and understood the following instructions and
the warning labels.

IMPORTANT: Servicing a double-insulated product requires extreme care and knowledge of the system, and
should be done only by qualified service personnel using identical replacement parts. Always use original factory
replacement parts when servicing.
1. Polarized Plugs. To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider
than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse
the plug. If it still does not fit, contact a qualified electrician to install a proper outlet. Do not modify the machine
plug or the extension cord in any way.
2. Ground fault circuit interrupter protection (GFCI) should be provided on the circuit or outlet used for this power
tool to reduce the risk of electric shock.
3. Service and repair. To avoid danger, electrical appliances must only be repaired by a qualified service technician
using original replacement parts.
GUIDELINES AND RECOMMENDATIONS FOR EXTENSION CORDS
When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An
undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. The table below shows
the correct size to be used according to cord length and ampere rating. When in doubt, use a heavier cord. The
smaller the gauge number, the heavier the cord.
DOUBLE-INSULATED CHARGER
The charger’s electrical system is double-insulated where two systems of insulation are provided. This
eliminates the need for the usual three-wire grounded power cord. Double-insulated tools do not need
to be grounded, nor should a means for grounding be added to the product. All exposed metal parts are
isolated from the internal metal components with protecting insulation.
1. Examine extension cord before use. Make sure your extension cord is properly wired and in good condition.
Always replace a damaged extension cord or have it repaired by a qualified person before using it.
2. Do not abuse extension cord. Do not pull on cord to disconnect from receptacle; always disconnect by pulling on
plug. Disconnect the extension cord from the receptacle before disconnecting the product from the extension cord.
Protect your extension cords from sharp objects, excessive heat and damp/wet areas.
3. Use a separate electrical circuit for your tool. This circuit must not be less than a 12-gauge wire and should be
protected with a 15A time-delayed fuse. Before connecting the motor to the power line, make sure the switch is in
the OFF position and the electric current is rated the same as the current stamped on the motor nameplate. Running
at a lower voltage will damage the motor.

• Avoid dangerous environments – Do not charge the
battery pack in rain, snow or in damp or wet locations.
Do not use the battery pack or charger in the presence
of explosive atmospheres (gaseous fumes, dust or flam-
mable materials) because sparks may be generated when
inserting or removing the battery pack, which could lead
to a fire.
• Charge in a well-ventilated area – Do not block the
charger vents. Keep them clear to allow for proper ven-
tilation. Do not allow smoking or open flames near a
charging battery pack. Vented gases may explode.
NOTE: The safe temperature range for the battery charg-
ing is 41°F to 104°F. Do not charge the battery outside in
freezing weather; charge it at room temperature.
• Maintain charger cord – When unplugging the char-
ger, pull the plug, not the cord, from the receptacle to
reduce the risk of damage to the electrical plug and cord.
Never carry the charger by its cord or yank it by the cord
to disconnect it from the receptacle. Keep the cord away
from heat, oil and sharp edges. Make sure the cord will
not be stepped on, tripped over or subjected to dam-
age or stress when the charger is in use. Do not use the
charger with a damaged cord or plug. Replace a dam-
aged charger immediately.
• Do not use an extension cord unless it is absolutely
necessary – Using the wrong, damaged or improperly
wired extension cord poses a risk of fire and electric
shock. If an extension cord must be used, plug the char-
ger into a properly wired 16 gauge or larger extension
cord with the female plug matching the male plug on the
charger. Make sure that the extension cord is in good
electrical condition.
• Charger is rated for 120 volt AC only – The charger
must be plugged into an appropriate receptacle.
• Use only recommended attachments – Use of an at-
tachment not recommended or sold by WEN Products
may result in risk of fire, electric shock or personal in-
jury.
• Unplug charger when not in use – Make sure to re-
move battery packs from unplugged chargers.
• Do not burn or incinerate battery packs – Battery
packs may explode, causing personal injury or dam-
age. Toxic fumes and materials are created when battery
packs are burned.
• Do not crush, drop or damage battery packs – Do not
use the battery pack or charger if they have sustained a
sharp blow, been dropped, run over or have been dam-
aged in any way (i.e. pierced with a nail, hit with a ham-
mer, stepped on, etc.).
• Do not disassemble – Incorrect reassembly may pose
a serious risk of electric shock, fire or exposure to toxic
battery chemicals. If the battery or charger are damaged,
call WEN customer service at 1-847-429-9263 for as-
sistance.
• Battery chemicals cause serious burns – Never let a
damaged battery pack contact the skin, eyes or mouth.
If a damaged battery pack leaks battery chemicals, use
rubber or neoprene gloves to safely dispose of it. If skin
is exposed to battery fluids, wash the affected area with
soap and water and rinse with vinegar. If eyes are ex-
posed to battery chemicals, immediately flush with wa-
ter for 20 minutes and seek medical attention. Remove
and dispose of contaminated clothing.
• Store your battery pack and charger in a cool, dry
place – Do not store the battery pack or charger where
temperatures may exceed 104 °F, such as in direct sun-
light or inside a vehicle or metal building during the
summer.
• Do not short circuit – A battery pack will short circuit if
a metal object makes a connection between the positive
and negative contacts on the battery pack. Do not place
a battery pack near anything that may cause a short cir-
cuit, such as paper clips, coins, keys, screws, nails and
other metallic objects. A short-circuited battery pack
poses a risk of fire and severe personal injury.
BATTERY & CHARGER SAFETY WARNINGS
Despite all of the safety precautions, caution must always be taken when handling batteries. The following
points must be obeyed at all times to ensure safe use. Safe use can only be guaranteed if undamaged cells are
used. Incorrect handling of the battery pack can cause cell damage.
WARNING! To reduce the risk of electric shock,
always unplug the charger before performing any
cleaning or maintenance. Do not allow water to
flow into the charger. Use a Ground Fault Circuit
Interrupter (GFCI) to reduce shock hazards.

BATTERY & CHARGER SAFETY WARNINGS
ABOUT THE BATTERY
1. The battery pack has to be charged completely before you use the tool for the first time.
2. For optimum battery performance, avoid low discharge cycles by charging the battery pack frequently.
3. Lithium-ion batteries are subject to a natural aging process. The battery pack must be replaced at the latest when
its capacity falls to just 80% of its capacity when new. Weakened cells in an aged battery pack are no longer capable
of meeting the high power requirements needed for the proper operation of your tool, and therefore pose a safety
risk.
4. Do not throw battery packs into an open fire as this poses a risk of explosion. Do not ignite the battery pack or
expose it to fire.
5. Do not exhaustively discharge batteries. Exhaustive discharge will damage the battery cells. The most common
cause of exhaustive discharge is lengthy storage or non-use of partially discharged batteries. Stop working as soon
as the performance of the battery falls noticeably or the electronic protection system triggers. Place the battery pack
in storage only after it has been fully charged.
6. Protect batteries and the tool from overloads. Overloads will quickly result in overheating and cell damage inside
the battery housing even if this overheating is not apparent externally.
7. Avoid damage and shocks. Immediately replace batteries that have been dropped from a height of more than
one meter or those that have been exposed to violent shocks, even if the housing of the battery pack appears to be
undamaged. The battery cells inside the battery may have suffered serious damage. In such instances, please read
the waste disposal information for proper battery disposal.
8. If the battery pack suffers overloading and overheating, the integrated protective cutoff will switch off the equip-
ment for safety reasons.
9. Use only original battery packs. The use of other batteries poses a fire risk and may result in injuries or an explo-
sion.
ABOUT THE CHARGER
Protect battery charger and cord from damage. Keep the charger and its cord away from heat, oil and sharp edges.
Electrical plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with ground-
ed appliances. Unmodified plugs and matching outlets will reduce the risk of electric shock.
Keep the battery charger, battery pack(s), and the cordless tool out of the reach of children.
Do not use the supplied battery charger to charge other cordless tools.
During periods of heavy use, the battery pack will become warm. Allow the battery pack to cool to room temperature
before inserting it into the charger to recharge.
Do not overcharge batteries. Do not exceed the maximum charging times. These charging times only apply to dis-
charged batteries. Frequent insertion of a charged or partially charged battery pack will result in overcharging and
cell damage. Do not leave battery in the charger for days on end.
Never use or charge a battery if you suspect that it has been more than 12 months since last time they were charged.
There is a high probability that the battery pack has already suffered dangerous damage (exhaustive discharge).
Do not use batteries that have been exposed to heat during the charging process, as the battery cells may have suf-
fered dangerous damage.
Do not use batteries that have suffered curvature or deformation during the charging process or those that exhibit
other atypical symptoms (gassing, hissing, cracking, etc.)

charged completely before you use the tool for the first time.
1. Connect charger to a 120V, 60Hz AC outlet. The green lights on the charger will illuminate, indicating that the
charger is powered.
2. Slide the battery all the way into the charger port until it clicks. The red light on the corresponding charger port
will illuminate, indicating that the battery is charging.
Charging Indication:
• Solid Green: Ready to Charge
• Solid Red: Charging
• Solid Green: Charged
3. When the battery is charged, the red light will turn off and the green light will turn on. Remove the battery from
the charger and unplug the charger from the power supply.
NOTE: Battery will not reach full charge the first time it is charged. Allow several cycles for the battery to fully
charge. The battery pack may become warm while charging; this is normal. If the battery is hot after continuous use
in the tool, allow it to cool to room temperature before charging. This will prolong the life of your battery.
The battery pack is equipped with three LED battery life indication lights. Press and hold the power button on the
front or rear of the battery to check the battery’s charge status.
Battery Life Indication:
• Three Lights: The battery is fully charged.

INSERTING AND REMOVING THE BATTERY
1. To install the battery, slide the battery pack into the battery port. Make sure the release latch on the rear side of
the battery pack snaps into place and the battery is secure before beginning operation.
2. To remove the battery pack, press the battery release latch on the front of the battery and pull the battery pack out.
WARNING! To avoid injury from accidental startups, be sure that the tool is switched OFF and the battery is
removed from the tool before inspecting the unit, making adjustments, or changing accessories.
LUBRICATING THE SAW CHAIN
Lubricate the saw chain with saw chain oil before each op-
eration. If the saw chain is not correctly lubricated, the risk
of wear on the guide bar, saw chain, and chain drive sprocket
increases.
Only use dedicated bar and chain oil designed for chainsaws.
Other oils will run the risk of damaging the unit and voiding
the warranty.
Take note of temperature conditions. Using the saw at vari-
ous temperatures requires the use of differing oils. To en-
sure a sufficient layer of lubricant at lower temperatures, use
lower-viscosity oil.
ASSEMBLING THE GUIDE BAR & SAW CHAIN
1. Place the saw body on a firm and level surface.
2. Turn the cover release knob (Fig. 1 - 1) counterclockwise
to remove the cover from the saw’s body.
3. While wearing protective gloves, wrap the saw chain
around the guide bar (Fig. 1 - 2), making sure that the teeth
are aimed in the direction of rotation (Fig. 2 - 1). The chain
should be properly set in the slot running along the entire
outside edge of the guide bar.
4. Place the saw chain around the sprocket (Fig. 2 - 2) while
lining up the slot in the guide bar with the bolt (Fig. 2 - 3) at
the base of the saw and the chain tensioning pin (Fig. 2 - 4)
in the guide bar’s pin hole. The chain tensioning pin may
need adjustment (see next section) to properly align with the
hole in the guide bar.
5. While holding the bar still, place the cover back onto the
saw. Adjust the tension (next section).

TENSIONING THE SAW CHAIN
ASSEMBLY & ADJUSTMENTS
Fig. 3
NOTE: The saw chain must be tensioned properly in order to
ensure safe operation. The chain tension is optimal if the saw
chain can be lifted 1/8 inch (3mm) from the center of the guide
bar. Since the saw chain heats up during operation, its length
can therefore fluctuate. Check the chain tension every 10 minutes
of operation and adjust as necessary, particularly for new saw
chains. Slacken the saw chain after the work is completed since
it shortens when cooling down. In doing so, you can elongate the
chain’s life and prevent damage.
1. Check the chain tension by pulling the saw chain away from the
guide bar. A properly tensioned chain should have roughly 1/8 inch (3
mm) of distance between itself and the bar guide (Fig. 3).
2. To adjust the saw chain tension, adjust the tension adjustment
screw (Fig. 4 - 1) with a Phillips-head screwdriver (not included).
Clockwise rotation increases the tension while counter-clockwise ro-
tation decreases tension. A properly tensioned chain should have no
sag and should only be able to be pulled 1/8 inch (3mm) away from
the guide bar of the saw. Do not over-tension the chain: this will lead
to excessive wear and reduce the life of both the bar and chain.

WARNING! When handling saw chains, always wear protec-
tive gloves to prevent injury.

OPERATION
PREPARING FOR OPERATION
Before each use, check the following items to ensure safe working conditions.
CHAINSAW: Before beginning work, inspect the chainsaw for damage to the housing, the saw chain, and the guide
bar. Never use an obviously damaged machine. Check that the chain guard operates properly.
CHAIN OIL: Check that the saw chain has been properly lubricated before beginning operation.
SAW CHAIN: Check the tension of the saw and the condition of the chain. The sharper the saw chain is, the easier
and more manageable operations will be. The same applies for the chain tension. Check the tension every 10 min-
utes of operation to maximize safety. New saw chains in particular are subject to changes due to the heat created by
operation. Never allow the saw chain to contact dirt or soil.
PROTECTIVE CLOTHING: Make absolutely sure to wear the appropriate close-fitting protective clothing, such as
protective pants, gloves and safety shoes. Wear a safety helmet with integrated hearing protection and a face guard
to provide protection against falling and recoiling branches.
SAFETY WARNINGS
1. In order to ensure safe work, do not operate the saw at an angle of over 60 degrees.
2. Never stand below a branch that is being sawed.
3. Exercise caution when sawing branches under tension or branches that are splintering.
4. Make sure to safeguard against the risk of injury from falling branches and flying wood projectiles.
5. If the machine is operating, keep people and animals away from the area.
6. The machine is not protected against electric shock when coming into contact with high-voltage lines. Maintain a
minimum clearance of 30 feet from current-carrying power lines to avoid life-threatening electric shock.
7. When working on an incline, always stand above or to the side of the branch being sawed.
8. Allow the chain to cut for you. Keep the saw running at full speed for the entire duration of the cut.
PREVENTING KICKBACK
The term kickback refers to when the saw suddenly jumps up and back. This is usually caused by the workpiece
coming into contact with the guide bar tip or the clamping of the saw chain.
A kickback generates an abrupt powerful force. The saw usually reacts in an uncontrolled manner, creating the pos-
sibility of injury to the user.
The danger of a kickback is greatest when attempting to cut near or with the guide bar tip. Always apply the saw as
flatly as possible in order to avoid a loss of control during operation.

WARNING! Do not cut down trees in high wind conditions. This can result in injury and should only be per-
formed by a trained professional.
OPERATION
POWERING ON / OFF THE CHAINSAW
1. Install the battery. Slide the battery pack into the battery
port. Make sure the release latch on the battery pack snaps
into place and the battery is secure before beginning opera-
tion.
To turn the tool ON: Press the power trigger lock (Fig. 5 - 1)
to unlock the power trigger. With the power lock pressed,
press the power trigger (Fig. 5 - 2) to start the chainsaw.
To turn the tool OFF: Release the power trigger. Once opera-
tion is complete, remove the battery from the chainsaw.
SAWING TECHNIQUES
When removing branches, hold the pole saw at an angle
ranging from 0 to 60° in order to avoid being struck by a fall-
ing branch. The saw should never be operated directly above
anyone’s head.
Saw off the lower branches on the tree first. By doing so, it is
easier for the cut branches to fall to the ground.
At the end of the cut, the weight of the saw suddenly in-
creases for the user since it is no longer being supported by
a branch. There is a risk of losing control of the saw, so make
sure to stay alert during the entire sawing operation.
Only pull the saw out of a cut while the saw is running. By
doing so, you prevent the chain from jamming in the wood.
Do not saw with the tip of the guide bar. Do not saw into the
branch formations (where the tree branches outwards). This
will impede the tree’s ability to heal.
For sawing off smaller branches, place the stop face (Fig. 6
- 1) of the saw on the branch. This prevents unwanted move-
ments of the saw at the beginning of the cut. While applying
light pressure, guide the saw through the branch from top to
bottom.

OPERATION
SAWING TECHNIQUES (CONT.)
For sawing off larger branches, first make a relief cut. Saw through
1/3 of the branch diameter from the bottom to top using the top side
of the guide bar. Then saw from top to bottom for the other 2/3 using
the bottom side of the guide bar. Saw off longer branches in sections
in order to maintain control over the location of impact (Fig. 7).
BUCKING A LOG
Bucking is cutting a log into lengths. It is important to make sure
your footing is firm and your weight is evenly distributed on both
feet. When possible, the log should be raised and supported by the
use of limbs, logs or chocks. Follow these simple directions for easy
cutting.
When the log is supported along its entire length (Fig. 8), it is cut
from the top (overbuck).
When the log is supported on one end (Fig. 9), cut 1/3 the diameter
from the underside (underbuck). Then make the finished cut by over-
bucking to meet the first cut.
When the log is supported on both ends (Fig. 10), cut 1/3 the diam-
eter from the top (overbuck). Then make the finished cut by under-
bucking the lower 2/3 to meet the first cut.
When bucking on a slope always stand on the uphill side of the log.
When cutting through, to maintain complete control, release the cut-
ting pressure near the end of the cut without relaxing your grip on the
chain saw handles. Don’t let the chain contact the ground. After com-
pleting the cut, wait for the saw chain to stop before you move the
chain saw. Always stop the motor before moving from tree to tree.
NOTE: Never allow the saw chain to contact dirt or soil, doing so will
severely dull the cutting links and shorten the life of the chain.

WARNING! Do not cut down trees in high wind conditions. This can result in injury and should only be per-
formed by a trained professional.
OPERATION
LIMBING A TREE
Limbing is removing the branches from a fallen tree. When limbing
leave larger lower limbs to support the log off the ground. Remove
the small limbs in one cut (Fig. 11). Branches under tension should
be cut from the bottom up to avoid binding the chain saw.

MAINTENANCE
ROUTINE INSPECTION
Before each use, inspect the general condition of the tool.
If any of these following conditions exist, do not use until
parts are replaced or the sharpener is properly repaired.
Check for:
• Loose hardware or improper mounting
• Misalignment or binding of moving parts
• Damaged battery or battery terminal
• Cracked or broken parts
• Any other condition that may affect its safe operation
CLEANING & STORAGE
1. Brush or blow dust and debris out of the air vents us-
ing compressed air or a vacuum. Keep the air vents free
of obstructions, sawdust, and wood chips. Do not spray,
wash, or immerse the air vents in water.
2. Wipe off the housing and the plastic components us-
ing a moist, soft cloth. Do not use strong solvents or
detergents on the plastic housing or plastic components.
Certain household cleaners may cause damage, and may
cause a shock hazard.
3. Routinely clean out the dust and debris that gathers
under the tension housing, the oil outlet, and around the
bar and the chain sprocket. Otherwise it can jam up the
sprocket, the chain, and the lubrication system.
4. If the pole saw is not used for an extended period of
time, remove the chain oil from the tank. Briefly place the
chain and the guide bar in an oil bath and then wrap in
oil paper to dry.
