When usmc 3erated chain saw, basic
READ ALL INSTRUCTIONS
• Keep all parts of the body away from the saw chain when the
chain saw is operating. Before you start the chain saw, make
sure the saw chain is not contacting anything. A moment of
inattention while operating chain saws may cause entanglement
of your clothing or body with the saw chain.
• Hold the power tool by insulated gripping surfaces only,
because the saw chain may contact hidden wiring or its own
cord. Saw chains contacting a "live" wire may make exposed
metal parts of the power tool "live" and could give the operator an
electric shock:
• Wear safety glasses and hearing protection. Further
protective equipment for head, hands, legs and feet is
recommended. Adequate protective clothing wifl reduce personal
injury by flying debris or accidental contact with the saw chain.
• Do not operate a chain saw in a tree. Operation of a chain saw
while up in a tree may result in personal injury.
• Always keep proper footing and operate the chain saw only
when standing on fixed, secure and level surface. Slippery or
unstable surfaces such as ladders may cause a loss of balance or
control of the chain saw.
• When cutting a limb that is under tension be alert for spring
back. When the tension in the wood fibres is released the spring
loaded limb may strike the operator and/or throw the chain saw
out of control.
• 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.
• Carry the chain saw by the front handle with the chain saw
switched off and away from your body. When transporting or
storing the chain saw always fit the guide bar cover. Proper
handling of the chain saw will reduce the fikelihood of accidental
contact with the moving saw chain.
• Follow instructions for lubricating, chain tensioning and
changing accessories. Improperly tensioned or lubricated chain
may either break or increase the chance for kickback:
o
Keep handles dry, clean, and free from oil and grease.
Greasy, oily handles are slippery causing loss of control.
o
Cut wood only. Do not use chain saw for purposes not
intended. For example: do not use chain saw for cutting
plastic, masonry or non-wood building materials. Use of the
chain saw for operations different than intended could result in a
hazardous situation.
Causes and operator prevention of 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.
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 chain saw user,
you should take several steps to keep your cutting jobs free from
accident or injury.
Kickback is the result of tool misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper
precautions as given below:
• Maintain a firm grip, with thumbs and fingers encircling the
chain saw handles, with both hands on the saw and position
your body and arm to allow you to resist kickback forces.
Kickback forces can be controlled by the operator, if proper
precautions are taken. Do not let go of the chain saw.
• Do not overreach and do not cut above shoulder height. This
helps prevent unintended tip contact and enables better control of
the chain 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 kickback:
The following precautions should be followed to minimize
kickback:
(1.) Grip Saw Firmly. Hold the chain saw firmly with both hands
when the motor is running. Use a firm grip with thumbs and fingers
encircling the chain saw handles. Chain saw will pull forward when
cutting on the bottom edge of the bar, and push backward when
cutting along the top edge of the bar.
(2.) Do not over reach.
(3.) Keep proper footing and balance at all times.
(4.) Don't let the nose of the guide bar contact a log, branch, ground
or other obstruction.
(5.) Don't cut above shoulder height.
(6.) Use devices such as low kickback chain and reduced kickback
uide bars that reduce the risks associated with kickback.
.) Only use replacement bars and chains specified by the
manufacturer or the equivalent.
(8.) Never let the moving chain contact any object at the tip of the
uide bar.
.) Keep the working area free from obstructions such as other
trees, branches, rocks, fences, stumps, etc. Eliminate or avoid
any obstruction that your saw chain could hit while you are cutting
through a particular log or branch.
(10.) Keep your saw chain sharp and properly tensioned. A loose
or dull chain can increase the chance of kickback. Check tension at
regular intervals with the motor stopped and battery removed, never
with the motor running.
(11.) Begin and continue cutting only with the chain moving at full
speed. If the chain is moving at a slower speed, there is a greater
chance for kickback to occur.
(12.) Cut one log at a time.
(13.) Use extreme caution when re-entering a previous cut. Engage
ribbed bumpers into wood and allow chain to reach full speed before
roceeding with cut.
14.) Do not attempt plunge cuts or bore cuts.
(15.) Watch for shifting logs or other forces that could close a cut
and pinch or fall into chain.
• Power Supply - Connect chain saw battery charger to correct
voltage, that is, be sure that the voltage supplied is the same as that
specified on the nameplate of the tool
ckbackSafety Features
WARNING: The following features are included on your saw
to help reduce the hazard of kickback; however such features
wilt not totally eliminate this dangerous reaction. As a chain saw user
do not rely only on safety devices. You must follow all safety
precautions, instructions, and maintenance in this manual to help
avoid kickback and other forces which can result in serious injury.
• Reduced-Kickback Guide Bar, designed with a small radius tip
which reduces the size of the kickback danger zone on bar tip. A
reduced - kickback guide bar is one which has been demonstrated to
significantly reduce the number and seriousness of kickbacks when
tested in accordance with safety requirements for electric chain saws.
• Low=Kickback Chain, designed with a contoured depth gauge and
guard link which deflect kickback force and allow wood to gradually
ride into the cutter. A low-kickback chain is a chain which has met
kickback performance requirements of ANSI B175.1-1991.
• Do not operate chain saw while in a tree, on a ladder, on a
scaffold, or from any unstable surface.
• Hold tool by insulated gripping surfaces when performing an
operation where the cutting tool may contact hidden wiring.
Contact with a "live" wire will make exposed metal parts of the tool
"live" and shock the operator.
• Do not attempt operations beyond your capacity or
experience. Read thoroughly and understandcompletely all
instructions in this manual.
• Before you start chain saw, make sure saw chain is not
contacting any object.
• Do not operate a chain saw with one hand! Serious injury
to the operator, helpers, or bystanders may result from one
handed operation. A chain saw is intended for two-handed use only.
• Keep the handles dry, clean, and free of oil or grease.
Do not allow dirt, debris, or sawdust to build up on the motor
or outside air vents.
• Stop the chain saw before setting it down.
• Do not cut vines and/or small under brush.
• Use extreme caution when cutting smatl size brush and
saplings because slender material may catch the saw chain and
!_be whipped toward you or pull you off balance.
WARNING: Some dust created by power sanding, sawing,
grinding, drilling, and other construction activities contains chemicals
known to the State of California to cause cancer, birth defects or
other reproductive harm. Some examples of these chemicals are:
• lead from lead-based paints,
crystalline silica from bricks and cement and other masonry
products, and
• 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 exposure to these
chemicals: work in a well ventilated area, and work with approved
safety equipment, such as those dust masks that are specially
designed to filter out microscopic particles.
• Avoid prolonged contact with dust from power sanding,
sawing, grinding, drilling, and other construction activities.
Wear protective clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth, eyes, or lay on the
_Nkin maypromote absorption of harmful chemicals.
ARNING: Use of this tool can generate and/or disburse dust,
which may cause serious and permanent respiratory or other injury.
Always use NIOSH/OSHA approved respiratory protection appropriate for
the dust exposure. Direct particles away from face and body.

• To adjust saw chain tension,
loosen the allen head screws (9).
• Rotate the tension adjustment
screw (20) in the front of the
housing using the flat screwdriver
end of the wrench (11) as shown
in figure F.
• Do not over-tension the chain as
this will lead to excessive wear
and will reduce the life of the bar and chain. Overtensioning also
reduces the amount of cuts you wilt get per battery charge.
Once chain tension is correct, tighten allen head screws (9).
When the chain is new check the tension frequently (after
disconnecting battery) during the first 2 hours of use as a new chain
stretches slightly.

Chain Oiling
• A high quality bar and chain oil or
SAE30 weight motor oil should be
used for chain and bar lubrication.
The use of a vegetable based bar and
chain oil is recommended when pruning
trees. Mineral oil is not recommended
because it may harm trees. Never use
waste oil or very thick oil. These may
damage your chain saw.
• Lubricate the whole chain evenly before each use as shown
in figure J. Also lubricate the chain whenever replacing a fully
discharged battery with a fully charged one.
Transporting Saw
• Always remove the battery (4) from
the tool (figure K) and cover the
guide bar (6) with the scabbard
(10) (figure L) when transporting
the saw. See the warning under
"Battery Cap Information"
for additional information on
transporting the battery.
Read and understand all instructions. Failure to
follow all instructions listed below may result in electric shock, fire
and/or serious personal injury.
• Guard Against Kickback which can result in severe injury
or death. See important Safety instructions "Guard Against
Kickback", to avoid the risk of kickback.
• Do not overreach. Do not cut above chest height. Make sure
your footing is firm. Keep feet apart. Divide your weight evenly on
both feet.
• Use a firm grip with your left hand on the front handle (15) and
your right hand on the rear handle (14) so that your body is to the
left of the guide bar.
• Do not hold chain saw by front hand guard (3). Keep elbow of
left arm locked so that left arm is straight to withstand a kickback.
z_WARNING: Never use a cross-handed grip (left hand on the
rear handle and right hand on the front handle).
z_WARNING: Never allow any part of your body to be in line with
the guide bar (6) when operating the chain saw.
• Never operate while in a tree, in any awkward position or on
a ladder or other unstable surface. You may lose control of saw
causing severe injury.
• Keep the chain saw running at full speed the entire time you
are cutting.
• Allow the chain to cut for you. Exert only light pressure. Do not
put pressure on chain saw at end of cut.
Connecting the Battery
• Place the battery (4) into the tool as
shown in figure M and be certain that it
is inserted fully into the tool cavity until it
"clicks" into place. To remove the battery
from the tool, press down on the release
button (21) on the back of the battery and
slide out.
Switch
• Always be sure of your footing and
grip the chain saw firmly with both
hands with the thumb and fingers
encircling both handles.
• To turn the tool ON push the lock
off button (2) to either side and
squeeze the trigger switch (1) with

• ToturnthetoolOFF,releasethetriggerswitch.
Chain Braking System
Your chain saw is equipped with a motor chain braking system which
wilt stop the chain quickly each time you release the trigger. This
system should be tested before every use.
Saw Chain Sharpness
The cutters wilt dull immediately if they touch the ground or a nail
while cutting. Refer to "Sharpening the Chain".
Saw Chain Tension
This should be done regularly. Refer to "Adjusting Chain Tension".
Common Cutting Techniques
Felling
Felling is the process of cutting down a tree. Be sure battery is
fully charged before felling a tree so you can finish on a single
charge. Do not fell trees in high wind conditions.
Bucking is the process of cutting a felled tree or log into lengths.
When bucking and felling operations are being performed by two
or more persons, at the same time, the felling operation should
be separated from the bucking operation by a distance of at least
twice the height of the tree being felled. Trees should not be felled
in a manner that would endanger any person, strike any utility line
or cause any property damage. If the tree does make contact with
any utility line, the utility company should be notified immediately.
Scrutinize the surrounding overhead for dead or broken limbs or
branches which may fall during the felling process.
The chain saw operator should keep on the uphill side of the
terrain as the tree is likely to roll or slide downhill after it is felled.
• (Figure O) A retreat path
should be planned and
cleared as necessary before
cuts are started. The retreat
path should extend back and
diagonally to the rear of the
expected line of fall.
• Before felling is started,
consider the natural lean
of the tree, the location of
larger branches and the wind
direction to judge which
way the tree will fall. Have wedges (wood, plastic or aluminum)
and a heavy mallet handy.
Remove dirt, stones, loose bark, nails, staples, and wire from the
tree where the felling cuts are to be made.
(Figure P) Notching
Undercut - Make the
notch 1/3 of the diameter
of the tree, perpendicular
to the direction of the fall.
Make the lower horizonta
notching cut first. This will
help to avoid pinching of
either the saw chain or
the guide bar when the
second notch is being
made.

• (Figure Q) Felling Back
Cut - Make the felling
back cut at least
2 inches (51 ram) higher
than the horizontal
notching cut. Keep the
felling back cut parallel
to the horizontal notching
cut. Make the felling back
cut so enough wood is
left to act as a hinge. The
hinge wood keeps the
tree from twisting and
falling in the wrong direction. Do not cut through the hinge.
• (Figure Q) As the felling cut gets close to the hinge the tree
should begin to fall. Ifthere is any chance that the tree may not fall
in the desired direction or it may rock back and bind the saw chain,
stop cutting before the felling cut is complete and use wedges to
open the cut and drop the tree along the desired line of fall. When
the tree begins to fall remove the chain saw from the cut, stop the
motor, put the chain saw down, then use the retreat path planned.
Be alert for overhead limbs falling and watch your footing.

Limbing (figure R)
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.
Branches under tension
should be cut from the
bottom up to avoid binding
the chain saw. Trim limbs
from opposite side keeping
tree stem between you
and saw. Never make cuts
with saw between your legs SUPPORT LIMBS UNTILLOG IS CUT
or straddle the limb to be cut.
Bucking
Bucking is cutting a felled tree or log into lengths. How you should
cut depends on how the log is supported. Use a saw horse
(figure W) whenever possible.
Always start a cut with the chain running at full speed and the
ribbed bumper (5) in contact with the wood. To complete the cut
use a pivoting action of the ribbed bumper against the wood.
• (Figure S) When
supported along its
whole length
Make a cut from the
top (overbuck), but
avoid cutting the earth
as this will dull your
saw quickly.

ground. After completing 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.
• (Figure W) When using a saw
horse
This is strongly recommended
whenever possible. Position the
log in a stable position. Always cut
on the outside of the saw horse
arms.
Use only mild soap and damp cloth to clean the tool. Do not use
solvents to clean the plastic housing of the saw. Never let any liquid
get inside the tool; never immerse any part of the tool into a liquid.
IMPORTANT: To assure product SAFETY and RELIABILITY,
repairs, maintenance and adjustment should be performed by
authorized service centers or other qualified service organizations,
always using identical replacement parts.
Regular maintenance ensures a long effective life for your chain
saw. We recommend you make the following checks on a regular
basis:
Chain and Bar
After every few hours of use, remove the guide bar and chain and
clean thoroughly.
Saw Chain Sharpening
z_CAUTION: Sharp chain. Always wear protective gloves when
handling the chain. The chain is sharp and can cut you when it is not
running.
Z_WARNING: Sharp moving chain. To prevent accidental
operation, insure that battery is disconnected from the tool
before performing the following operations. Failure to do this
could result in serious personal injury.
To get the best possible performance from your chain saw it is
important to keep the teeth of the chain sharp. Follow these helpful
tips for proper saw chain sharpening:
1. For best results use a 4.5mm file and a file holder or filing guide
to sharpen your chain. This will ensure you always get the correct
sharpening angles.
2. Place the file holder flat on the top plate and depth gauge of the
cutter.

processes (2,3,4) for cutters on
the other side of the chain. Use a flat file to file the tops of the
rakers (portion of chain link in front of the cutter) so that they are
about .025 inch (.635 mm) below the tips of the cutters.
5. (Figure Z) Keep all cutter
lengths equal.
6. If damage is present on the
chrome surface of the top plates
or side plates, file back until
such damage is removed.
z_CAUTION: After filing, the cutter will be sharp, use extra caution
during this process.
NOTE: Each time the chain is sharpened, it loses some of the
low kickback qualities and extra caution should be used. It is
recommended that a chain be sharpened no more than four times.
