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.

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.)

2. Using the included blade nut wrench, loosen and remove the blade
nut (Fig. 1 - 2). Turn the nut counterclockwise to loosen it.
3. Using a Phillips head screwdriver (not included), loosen and re-
move the two side cover screws (Fig. 2 - 1).

4. Slide the side cover (Fig. 2 - 2) forward (toward the blades) and carefully remove it from the pruner.
5. Carefully lift the old blade off and replace with the new blade, making sure the gear teeth of the blade mesh with
the drive gear on the tool.
6. Replace the side cover, side cover screws, blade nut, and blade screw.
7. Before beginning operation, make sure that the blade and fasteners are securely installed.
TIGHTENING THE BLADE
WARNING! Switch the tool OFF and remove the battery before tightening the blade.
1. Check to ensure the blade is tight before each use. A well tightened blade should not move from left to right.
2. Using the included 2.5mm hex wrench, loosen and remove the blade screw (Fig. 1 - 1). Turn the screw clockwise
to loosen it (it is left-hand threaded).
3. Using the included blade nut wrench, adjust the blade nut (Fig. 1 - 2) tension until the tool clicks. Turn the nut
clockwise to tighten it.
4. Replace the blade screw and check the tightness of the blade.
It is possible to have slight movement in the direction of blade closure. This movement is normal and may be caused
by the gap between the rack and pinion teeth.
WARNING! To avoid accidents, turn the tool OFF and remove the battery from the battery terminal before
cleaning, adjusting, or performing any maintenance or lubrication work.

LUBRICATING THE BLADE
For easier operation and a longer blade life, lubricate the blade before
and after each use. If you are planning to use the pruner for an ex-
tended period of time, it is advised to lubricate the blade periodically
during operation.
NOTE: Oil is not included with this tool. The blade comes pre-oiled
from the factory and only needs to be oiled for general maintenance.
We recommend using general-purpose machine oil.
1. Locate the oil inlet (Fig. 3 - 1) on the side of the pruner.
2. Place the oil bottle nozzle into the lubricating inlet and lubricate
the blades.

3. Open and close the blade of the tool several times to distribute the oil.
SHARPENING THE BLADE
WARNING! Switch the tool OFF and remove the battery before sharpening the blade.
WARNING! Always wear protective gloves when sharpening the blade. Handle the blade with caution.
If the blade becomes dull, and starts to crush branches instead of cut them, it should be sharpened. If the blade is
heavily nicked, damaged, or warped, it should be replaced (see section “REPLACING THE BLADE”).
1. Use a fine-toothed file. Keeping the file flush with the existing blade bevel, use light, firm pressure to push the file
from the heel of the blade towards the tip.
2. Lift the file off the blade.
3. Repeat until the blade is sharpened.
4. Remove any burrs from the blade.
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.
PRODUCT DISPOSAL
Used power tools should not be disposed of together
with household waste. This product contains electronic
components that should be recycled. Please take this
product to your local recycling facility for responsible
disposal and to minimize its environmental impact.
WARNING! To avoid accidents, turn the tool OFF and remove the battery from the battery terminal before
cleaning, adjusting, or performing any maintenance or lubrication work.
WARNING! Any attempt to repair or replace electrical parts on this tool may be hazardous. Servicing of the
tool must be performed by a qualified technician. When servicing, use only identical WEN replacement parts.
Use of other parts may be hazardous or induce product failure.
DISINFECTING THE BLADE
Pruning tools should be disinfected to prevent the
spread of pathogens among plants. Although it is not
always practical to handle disinfectants when making
multiple cuts on the same tree or pruning several trees
or shrubs, it will minimize plant loss.
Ethanol or isopropyl alcohol are ideal for sanitizing
pruning equipment because blades can simply be wiped
or dipped into disinfectant without a prolonged soak.
Products sold as rubbing alcohol usually contain 70%
isopropyl alcohol and can be used directly from the con-
tainer. Be sure to follow the label's safety precautions.
STORING THE BATTERY AND CHARGER
• Make sure the battery is fully charged before storage in
order to maximize the life of the battery.
• Do not store the battery pack on the tool. Remove the
battery from the tool before storage.
• After charging, the battery pack may be stored in the
charger, as long as the charger is not plugged in.
• Store the charger at normal room temperature. Do not
store it in excessive heat. Do not use the charger in di-
rect sunlight or in damp conditions. Do not charge out-
side. Recharge at room temperature.
• Keep the charger clean and clear of debris. Do not al-
low foreign material to get into the recessed cavity or
onto the contacts. Wipe the charger clean with a dry
cloth. Do not use solvents or water, and do not place the
charger in wet conditions.
• Always unplug the charger when charging is complete.
Never leave your charger plugged in if it is not charging
a battery.
