GENERAL MACHINE SAFETY
WARNINGS
WARNING:
Read all safety
warnings, instructions, illustrations and
specifications provided with this machine.
Failure to follow all instructions listed below
may result in electric shock, re and/or
serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS
FOR FUTURE REFERENCE.
The term “machine” in the warnings refers
to your mains-operated (corded) machine
or battery-operated (cordless) machine.
WORK AREA SAFETY
1. Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
2. Do not operate machines in explosive
atmospheres, such as in the presence of
ammable liquids, gases or dust. Machines
create sparks which may ignite the dust or
fumes.
3. Keep children and bystanders away
while operating a machine. Distractions
can cause you to lose control.
ELECTRICAL SAFETY
1. Machine plugs must match the outlet.
Never modify the plug in any way. Do
not use any adapter plugs with earthed
(grounded) machines. Unmodied plugs
and matching outlets will reduce risk of
electric shock.
2. Avoid body contact with earthed
or grounded surfaces, 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 machines to rain or wet
conditions. Water entering a machine will
increase the risk of electric shock.
4. Do not abuse the cord. Never use the
cord for carrying, pulling or unplugging
the machine. 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 machine outdoors,
use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use
reduces the risk of electric shock.
6. If operating a machine in a damp
location is unavoidable, use a ground fault
circuit interrupter (GFCI) protected supply.
Use of an GFCI reduces the risk of electric
shock.
PERSONAL SAFETY
1. Stay alert, watch what you are doing
and use common sense when operating
a machine. Do not use a machine while
you are tired or under the inuence of
drugs, alcohol or medication. A moment of
inattention while operating machines may
result in serious personal injury.
2. Use personal protective equipment.
Always wear eye protection. Protective
equipment such as a dust mask, non-skid
safety shoes, hard hat or hearing protection
used for appropriate conditions will reduce
personal injuries.
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 machine.
Carrying machines with your nger on the
switch or energizing machines that have the
switch on invites accidents.
4. Remove any adjusting key or wrench
before turning the machine on. A wrench or
a key left attached to a rotating part of the
machine may result in personal injury.
5. Do not overreach. Keep proper footing
and balance at all times. This enables
better control of the machine in unexpected
situations.

correct machine for your application. The
correct machine will do the job better and
safer at the rate for which it was designed.
2. Do not use the machine if the switch
does not turn it on and off. Any machine
that cannot be controlled with the switch is
dangerous and must be repaired.
3. Disconnect the plug from the power
source and/or remove the battery pack,
if detachable, from the machine before
making any adjustments, changing
accessories, or storing machines. Such
preventive safety measures reduce the risk
of starting the machine accidentally.
4. Store idle machines out of the reach
of children and do not allow persons
unfamiliar with the machine or these
instructions to operate the machine.
Machines are dangerous in the hands of
untrained users.
5. Maintain machines and accessories.
Check for misalignment or binding of
moving parts, breakage of parts and
any other condition that may affect the
machine’s operation. If damaged, have
the machine repaired before use. Many
accidents are caused by poorly maintained
machines.
6. Keep cutting machines sharp and clean.
Properly maintained cutting machines with
sharp cutting edges are less likely to bind
and are easier to control.
7. Use the machine, accessories and
machine bits etc. in accordance with
these instructions, taking into account
the working conditions and the work to
be performed. Use of the machine for
operations different from those intended
could result in a hazardous situation.
8. Keep handles and grasping surfaces
dry, clean and free from oil and grease.
Slippery handles and grasping surfaces do
not allow for safe handling and control of the
machine in unexpected situations.
BATTERY MACHINE USE AND
CARE
1. Recharge only with the charger
specied by the manufacturer. A charger
that is suitable for one type of battery pack
may create a risk of re when used with
another battery pack.
2. Use machines only with specically
designated battery packs. Use of any other
battery packs may create a risk of injury and
re.
3. When battery pack is not in use, keep
it away from other metal objects, like
paper clips, coins, keys, nails, screws or
other small metal objects, that can make a
connection from one terminal to another.
Shorting the battery terminals together may
cause burns or a re.
4. Under abusive conditions, liquid may
be ejected from the battery; avoid contact.
If contact accidentally occurs, ush with
water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the
battery may cause irritation or burns.
5. Do not use a battery pack or machine
that is damaged or modied. Damaged or
modied batteries may exhibit unpredictable
behavior resulting in re, explosion or risk of
injury.
Page 6
SAFETY INSTRUCTIONS
6. Do not expose a battery pack or
machine to re or excessive temperature.
Exposure to re or temperature above
265 °F (130 °C) may cause explosion.
7. Follow all charging instructions and
do not charge the battery pack or machine
outside the temperature range specied in
the instructions. Charging improperly or at
temperatures outside the specied range
may damage the battery and increase the
risk of re.
SERVICE
1. Have your machine serviced by a
qualied repair person using only identical
replacement parts. This will ensure that the
safety of the machine is maintained.
2. Never service damaged battery
packs. Service of battery packs should
only be performed by the manufacturer or
authorized service providers.
SAFETY INSTRUCTIONS FOR
PRUNING SAW
1. Keep all parts of the body away
from the saw chain when the pruning
saw is operating. Before you start the
pruning saw, make sure the saw chain
is not contacting anything. A moment of
inattention while operating pruning saws
may cause entanglement of your clothing or
body with the saw chain.
2. Do not reach underneath the lumber.
The guard cannot protect you from the saw
chain below the lumber.
3. Check the chain guard for proper
closing before each use. Do not operate
the pruning saw if the guard does not move
freely and close instantly. Never clamp or
tie the chain guard into the open position.
If the pruning saw is accidentally dropped,
the guard may be bent. Raise the guard
and make sure it moves freely and does not
touch the saw chain or any other part, in all
angles.
4. Check the operation of the chain guard
spring. If the guard and the spring are not
operating properly, they must be serviced
before use. Chain guard may operate
sluggishly due to damaged parts, gummy
deposits, or a build-up of debris.
5. Do not at any time point the lower
part or the tip of the pruning saw towards
anyone or anything other than the wood to
be cut. The saw chain on the bottom part
of the guide bar is not covered by a guard,
which may cause serious damage or injury if
it points to something or someone.
6. Always hold the pruning saw rmly with
one hand. Holding the pruning saw with two
hands increases the risk of personal injury
and should never be done.
7. Hold the pruning saw by insulated
gripping surfaces only, because the saw
chain may contact hidden wiring. Saw
chains contacting a “live” wire may make
exposed metal parts of the pruning saw
“live’” and could give the operator an
electric shock.
8. Wear safety glasses and hearing
protection. Further protective equipment
for hearing, head, hands, legs and feet
is recommended. Adequate protective
equipment will reduce personal injury from
ying debris or accidental contact with the
saw chain.
9. Do not operate a pruning saw on a
ladder, from a rooftop, or any unstable
support. Operation of a pruning saw in this
manner could result in serious personal
injury.
10. Always keep proper footing and operate
the pruning saw only when standing on
xed, secure and level surface. Slippery
or unstable surfaces may cause a loss of
balance or control of the saw.
11. When cutting a limb that is under
tension, be alert for spring back. When the
tension in the wood bers is released, the
spring-loaded limb may strike the operator
and/or throw the pruning saw out of control.
Page 7
12. Use extreme caution when cutting
brush and saplings. The slender material
may catch the saw chain and be whipped
toward you or pull you off balance.
13. Carry the pruning saw by the handle
with the pruning saw switched off and
away from your body. When transporting
or storing the pruning saw, always t the
guide bar cover. Proper handling of the
pruning saw will reduce the likelihood of
accidental contact with the moving saw
chain.
14. Follow instructions for lubricating,
chain tensioning and changing
accessories. Improper tension or lubrication
may cause the chain to break.
15. Keep handles dry, clean, and free from
oil and grease. Greasy, oily handles are
slippery, causing loss of control.
16. Cut wood only. Do not use pruning saw
for purposes not intended. For example:
do not use pruning saw for cutting plastic,
masonry, or non-wood building materials.
Use of the pruning saw for operations
different than intended could result in a
hazardous situation.
CAUSES AND OPERATOR
PREVENTION OF KICKBACK
(FIG. 1a, 1b, 1c):
FIG. 1a
Rotational
Kickback
SAFETY INSTRUCTIONS
FIG. 1b
Kickback
Danger Zone
注意：机器部分同figb
FIG. 1d
FIG. 1c
Pinch
Kickback
Kickback may occur when the nose or tip of
the guide bar touches an object, or when the
wood closes in and pinches the saw chain
in the cut.
Page 8
SAFETY INSTRUCTIONS
Tip contact in some cases may cause a
sudden reverse reaction, kicking the guide
bar up and back towards the operator.
Pinching the saw chain along the top of the
guide bar may push the guide bar rapidly
back towards the operator.
Either of these reactions may cause you
to lose control of the saw, which could
result in serious personal injury. Do not rely
exclusively upon the safety devices built into
your saw. As a pruning saw user, you should
take several steps to keep your cutting jobs
free from accident or injury.
Kickback is the result of machine misuse
and/or incorrect operating procedures or
conditions and can be avoided by taking
proper precautions as given below:
• Maintain a firm grip with only one hand
on the saw and position your body and
arm to allow you to resist kickback forces
(FIG. 1d). Kickback forces can be controlled
by the operator, if proper precautions are
taken. Do not let go of the pruning saw.
• Do not overreach and do not cut
above shoulder height. This helps prevent
unintended tip contact and enables better
control of the saw in unexpected situations.
• Only use replacement bars and chains
specified by the manufacturer. Incorrect
replacement bars and chains may cause
chain breakage and/or kickback.
• Follow the manufacturer’s sharpening
and maintenance instructions for the saw
chain. Decreasing the depth gauge height
can lead to increased risk of injury.
CAUSES AND OPERATOR
PREVENTION OF PULL-IN
(FIG. 1e):
注意：机器部分同figb
FIG. 1e
Bumper
WARNING:
Pull-in occurs when the chain on the
bottom of the bar is suddenly stopped or
significantly slowed when it is pinched,
caught or encounters a foreign object
in the wood. The reaction of the chain
pulls the saw forward and may cause the
operator to lose control, which, in turn,
may cause serious or fatal injury.
Pull-in usually occurs when the bumper
of the saw is not held securely against the
branch or limb and the chain is not rotating
at full speed before it contacts the wood.
To reduce the risk of pull-in:
- Cut with a sharp, properly tensioned
chain.
- Always start a cut with the chain rotating
at full speed and with the bumper in contact
with the wood.
- Use caution when cutting small-size
brush, branches and saplings which may
easily catch the chain, spring towards you
or pull you off balance.
- Do not use the saw with a damaged or
missing guard.
Page 9
SAFETY INSTRUCTIONS
ADDITIONAL SAFETY WARNINGS
注意：机器部分线图同figb,把figb平面旋转下
FIG. 1f
Pull (FIG. 1f) – The reaction force is always
opposite to the direction the chain is
moving where wood contact is made. Thus,
the operator must be ready to control the
PULL when cutting with the bottom edge
of the bar.

The pruning saw is not lled with oil at the
time of purchase. It is essential to ll the
tank with oil before use. Operating the saw
without chain oil or when the oil level is be-
low the minimum mark will result in damage
to the saw. Chain life and cutting capacity
depend on optimum lubrication.
The chain is automatically lubricated with
chain oil during operation.
WARNING:
Do not smoke or
bring any fire or flame near the oil or the
pruning saw. Oil may spill and cause a fire.
1. Remove the battery pack from the
pruning saw.
2. Clean the oil-tank cap and the area
around it to ensure that no dirt falls into
the oil tank.
3. Position the pruning saw on its side on a
rm, at surface, so that the oil-tank cap
is facing up. Lift the cap tab and rotate it
counterclockwise to remove the cap.
4. Carefully pour the bar and chain oil into
the tank. Fill to the bottom of the ll
neck. Wipe off any excess oil.
5. Replace and tightly secure the cap. Fold
the cap tab.
6. Place the saw upright and examine the
oil level through the translucent plastic
oil tank.
NOTICE:
We recommend using environmentally-
friendly biodegradable chain oil specically
intended to be used with pruning saws.
Never use oil or other lubricants not
specically designed for use on the bar and
chain. This can lead to a clogged oil system,
which may cause premature wear of the bar
and chain.
Check the oil level frequently and ll
the tank when the oil level falls below the
minimum line. Never operate the pruning
saw if the oil is not visible.
Do not use dirty, used, or otherwise
contaminated oil. Damage may occur to the
bar or chain.
It is normal for oil to seep from the saw
when it is not in use. To prevent seepage,
empty the oil tank after each use and then
run the saw for one minute. When storing
the machine for a long period of time, be
Page 14
sure that the chain is lightly lubricated.
This will prevent rust on the chain and bar
sprocket.
To preserve natural resources, please recy-
cle or dispose of oil properly. Consult your
local waste authority for information regard-
ing available recycling and disposal options.

OPERATION
Page 16
OPERATION
Work Area Precautions
Cut only wood or materials made from
wood. Do not cut sheet metal, plastics,
masonry, or non-wood building materials.
Never allow children to operate the
pruning saw.
Allow no person, who has not read this
Operator’s Manual or received adequate
instructions for the safe and proper use of
this saw, to use this saw.
During bucking operations, keep a
minimum distance of 15 feet between
workers. Trees should not be felled in a
manner that would endanger any person,
strike any utility line, or cause any property
damage. If a tree does make contact with
any utility line, stay clear of the tree and
the line and notify the utility company
immediately.
Always operate the saw with both feet
on solid ground to prevent being pulled off
balance.
Do not cut above shoulder height, as a
saw held higher is difcult to control against
kickback forces.
Do not fell trees near electrical wires or
buildings.
Cut only when visibility and light are
adequate for you to see clearly.
Proper Grip on Handle
Wear non-slip gloves for maximum grip and
protection. With the saw on a rm, at sur-
face, hold the saw rmly with one hand. The
ngers should encircle the handle (FIG. 7).
BASIC CUTTING
WARNING:
Always be sure of your
footing and hold the pruning saw firmly
with one hand while the motor is running.
Practice cutting a few small logs using the
following technique to get the “feel” of
using your saw before you begin a major
sawing operation.
1. Take the proper stance in front of the
wood with the saw off.
2. Press the lock-off button and squeeze
the trigger to start the saw. Let the
saw chain reach the full speed before
beginning the cut.
3. Begin cutting by lightly pressing the
guide bar against the wood. Use only
light pressure, letting the saw do the
work.
4. Maintain a steady speed throughout the
cut, releasing pressure just before the
end of the cut.
5. Release the trigger as soon as the cut
is completed, allowing the saw chain to
stop.
WARNING:
When the saw chain is stopped due to
pinching during cutting, release the trigger
switch; remove the saw chain and guide
bar from the wood, then restart the pruning
saw.
Do not pull the saw chain with your
hand when it is bound by the sawdust.
Serious injury could result if the saw starts
accidentally. Press the saw chain against
the wood, move the saw back and forth to
discharge the debris. Always remove the
battery pack before cleaning. Wear heavy
protective gloves when handling the saw

LIMBING (FIG. 8)
FIG. 8
Limb Cut
Limbing is removing branches from a fallen
tree. When limbing, leave larger limbs to
support the log off the ground. Use the
pruning saw to remove the small limbs in
one cut as illustrated in FIG. 8.
WARNING:
There is an extreme danger of kickback
during the limbing operation. Be extremely
cautious and avoid contacting the log or
other limbs with the tip of the guide bar.
The saw is not suitable for bottom-up
cutting as its chain guard mustn’t be lifted
during operation. Never use it to cut the
support branches under tension.
NOTICE: For better performance, do not cut
a branch with a diameter greater than 5.5 in..

Pruning is trimming limbs from a live tree.
• Work slowly, keeping your hand on the
pruning saw with a rm grip. Always make
sure your footing is secure and your weight
is distributed evenly on both feet.
• Do not cut from a ladder, this is
extremely dangerous. Leave this operation
for professionals.
• Do not cut above shoulder height as a
saw held higher is difcult to control against
kickback.
• When pruning trees, be aware of the risk
of stripping the bark from the main limb or
trunk when the cut is made next to the main
limb or trunk.
WARNING:
If the limbs to be
pruned are above shoulder height, hire a
professional to perform pruning. Failure
to do so could result in serious personal
injury.
NOTICE: For better performance, do not cut
a branch with a diameter greater than
5.5 in.

Bucking is cutting a log into lengths. It is im-
portant to make sure your footing is rm and
your weight is evenly distributed on both
feet. The log should be supported along its
entire length. Follow these simple directions
for easy cutting.
OPERATION
WARNING:
Keep the cutting area
clear. Make sure that no objects can
contact the guide bar nose and chain
during cutting. This can cause kickback.
Overbucking (FIG. 10a).
Begin on the top side of the log with the bot-
tom of the saw against the log, exert light
pressure downward. Note that the saw will
tend to pull away from you. Engage the
pruning saw bumper against the log when-
ever possible.
Make sure that the log is supported
along its entire length before you make a cut
from the top (overbucking) (FIG. 10b).
NOTICE: For better performance, do not cut
a log with a diameter greater than
5.5 in.
.
When bucking on a slope, always stand
on the uphill side of the log.
To maintain complete control when
cutting through, release the cutting pressure
near the end of the cut without relaxing
the grip on the pruning saw handle. Don’t
allow the chain to contact the ground. After
completing the cut, wait for the saw chain to
stop before you move the saw. Always stop
the motor before moving from tree to tree.

WARNING:
Remove the battery pack before
performing any maintenance. Failure to
heed this warning could result in serious
personal injury.
Always wear gloves when handling the
saw chain. The chain is sharp and may
contain burrs.
Use only low-kickback chains on this saw.
This fast-cutting chain will provide kickback
reduction when properly maintained.
A properly sharpened saw chain cuts
through wood effortlessly, even with very
little pressure.
Never use a dull or damaged saw chain.
A dull saw chain cutter leads to increased
physical strain, increased vibration load,
unsatisfactory cutting results and increased
wear.
For smooth and fast cutting, the saw chain
needs to be maintained properly. When the
wood chips are small and powdery, the
chain must be forced through the wood dur-
ing cutting, or the chain cuts to one side are
the indicators that the chain requires sharp-
ening. During maintenance of your saw
chain, consider the following:
Improper ling angle of the side plate
can increase the risk of a severe kickback.
Raker (depth gauge) clearance. Too low
increases the potential for kickback. Not low
enough decreases cutting ability.
If cutter teeth have hit hard objects, such
as nails and stones, or have been abraded
by mud or sand on the wood, have the chain
sharpened by a qualied service technician.
NOTICE: Inspect the drive sprocket for
wear or damage when replacing the chain.
If signs of wear or damage are present in
the areas indicated, have the drive sprocket
replaced by qualied service technician.
Sharpen the Cutters
Be sure to le all cutters (FIG. 13a) to the
specied angles and to the same length, as
fast cutting can be obtained only when all
cutters are uniform.
1. Remove the battery pack. Wear gloves
for protection.
2. Properly tension the chain prior to
sharpening. Refer to the section:
“ADJUSTING THE CHAIN TENSION”
earlier in this manual.
3. Use a 5/32ʺ diameter round le and
holder (available separately). Do all of
your ling at the middle position of the
guide bar.
4. Keep the le level with the top plate of
the tooth. Do not let the le dip or rock.
5. Keep a correct sharpening angle of 30°
between the le and the saw chain (see
FIG. 13b & 13c). Always use a le holder
(available separately) when sharpening
saw chains by hand. File holders have
markings for the sharpening angle.
6. Using light but rm pressure, perform a
stroke towards the front corner of the
tooth. Lift the le away from the steel on
each return stroke.
7. Make a few rm strokes on every tooth.
File all left hand cutters in one direction.
Then move to the other side and le
the right-hand cutters in the opposite
direction. Occasionally remove lings
from the le with a wire brush (FIG. 13d).

Guide-bar Tip
The bar should be cleaned every day of
use and checked for wear and damage.
Feathering or burring of the bar rails is a
normal process of bar wear. Such faults
should be smoothed with a le as soon as
they occur. A bar with any of the following
faults should be replaced:
Wear inside the bar rails that permits the
saw chain to lay over sideways.
Bent guide bar.
Cracked or broken rails.
Spread rails.
In addition, the guide bar has a sprocket
at its tip. The sprocket must be lubricated
weekly with a grease syringe to extend
the guide bar life. Use a grease syringe to
lubricate weekly with chain oil by means of
the lubricating hole (FIG. 14) on each side
of the bar. Turn the guide bar and check
that the lubrication holes and chain groove
are free from impurities.
Page 26
MAINTENANCE
When the guide bar shows signs of wear,
reverse it on the saw to distribute the wear
for maximum bar life.
1. Remove the guide bar and chain from
the pruning saw, following the section
“REPLACING THE BAR AND CHAIN”.
2. Turn the guide bar over. The bottom of
the bar will be on the top (Fig. 14).
3. Adjust the chain tension, following
the section “ADJUSTING THE CHAIN
TENSION”.
TRANSPORTING AND STORING
Do not store or transport the pruning
saw when it is running. Always remove
the battery pack before storing or
transporting.
Always place the chain sheath on the
guide bar and chain before storing
or transporting the pruning saw. Use
caution to avoid the sharp teeth of the
chain.
Clean the pruning saw thoroughly before
storing. Store the saw indoors, in a dry
place that is locked and/or inaccessible
to children.
