CHAIN SAW SAFETY WARNINGS
11. Do not modify or attempt to repair the power tool or the battery pack (as applicable) except as indicated
in the instructions for use and care.
1. 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 that the saw chain is not contacting anything. A moment of inattention while oper-
ating chain saws may cause entanglement of your clothing or body with the chain.
2. Always hold the chain saw with your right hand on the rear handle and your left hand on the front handle.
never be done.
3. Hold the power tool by insulated gripping surfaces only, because the saw chain may contact hidden wiring.
4. Wear safety glasses and hearing protection. Further protective equipment for head, hands, legs and feet
contact with the saw chain.
5. Do not operate a chain saw in a tree. Operation of a chain saw while up in a tree may result in personal
injury.

face. Slippery or unstable surfaces such as ladders may cause a loss of balance or control of the chain
saw.
released the spring loaded limb may strike the operator and/or throw the chain saw out of control.
8. Use extreme caution when cutting brush and saplings. The slender material may catch the saw chain and
reduce the likelihood of accidental contact with the moving saw chain.
10. Follow instructions for lubricating, chain tensioning and changing accessories. Improperly tensioned or
lubricated chain may either break or increase the chance for kickback.
11. Keep handles dry, clean, and free from oil and grease. Greasy, oily handles are slippery and cause loss
of control.
12. Cut wood only. Do not use chain saw for purposes not intended. For example: do not use chain saw for
than intended could result in a hazardous situation.
13. A chain saw is intended for two-handed use. Serious injury to the operator, helpers, and/or bystanders
can result from one-handed operation.
14. Avoid unintentional contact with the stationary saw chain or guide bar rails. These can be very sharp.
Always wear gloves and long pants or chaps when handling the chain saw, saw chain, or guide bar.
15. Never operate a chain saw that is damaged or improperly adjusted or that is not completely and securely
assembled. Be sure that the saw chain stops moving when the trigger switch is released.
16. Inspect the work piece for nails, wire, or other foreign objects prior to cutting.
17. When bucking, secure the work piece prior to cutting. When felling or pruning, identify and secure haz-
ardous branches.
18. Aggressive or abusive cutting or misuse of the chain saw can cause premature bar, chain, and/or sprocket
wear, as well as a broken chain or bar, leading to kickback, chain throw or the ejection of material.
19. Never use the guide bar as a lever. A bent guide bar can cause premature bar, chain, and/or sprocket
wear, as well as a broken chain or bar, leading to kickback, chain throw or the ejection of material.
20. Cut only one work piece at a time.
21. Plan the work, ensuring an obstacle-free work area and, in the case of felling, at least one escape path
from the falling tree.
22. When felling, keep bystanders at least two tree lengths away.
23. If situations occur that are not covered in this manual, use care and good judgment. Contact the Customer
Service Center.
06
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:

encircling the chain saw handles, with both
hands on the saw and position your body and
arm to allow you to resist kickback forces (Fig. 4).
Kickback forces can be controlled by the opera-
tor, if proper precautions are taken. Do not let go
of the chain saw.
2. 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.
by the manufacturer. Incorrect replacement bars
and chains may cause chain breakage and/or
kickback.
4. Follow the manufacturer’s sharpening and main-
tenance instructions for the saw chain. Decreas-
ing the depth gauge height can lead to increased
kickback.
5. Make sure that the area in which you are cutting
is free from obstructions. Do not let the nose of
the guide bar contact a log, branch, fence, or any
other obstruction that could be hit while you are
operating the saw.
6. Always cut with the unit running at full speed.
Fully squeeze the switch trigger and maintain
cutting speed do not force.
7. With a basic understanding of kickback, you can
reduce or eliminate the element of surprise. Sudden
surprise contributes to accidents.
8. Keep proper footing and balance at all times.
9. Push and Pull – 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
on the bottom edge of the bar, and the PUSH
when cutting along the top edge. See
The rakers (depth gauges) ahead of each cutter can
minimize the force of a kickback reaction by pre-
venting the cutters from digging in too deeply at the
kickback zone. Only use a replacement chain that is
equivalent to the original chain.See
This saw comes equipped with a guide bar that has a small radius nose. Small radius noses generally have
less potential for kickback. When replacing the guide bar, be sure to order the bar listed in this manual.

CUTTING
FELLING A TREE
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.
Basic Cutting
Hazardous Conditions
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 com-
The chain saw operator should stand on the uphill
side of the terrain, as the tree is likely to roll or
slide downhill after it is felled.
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.
Remove dirt, stones, loose bark, nails, staples,
and wire from the tree where felling cuts are to
be made.
Make the notch 1/3 the diameter of the tree,
perpendicular to the direction of fall, as illustrated
in Make the lower horizontal notching
the saw chain or the guide bar when the second
notch is being made.
Limbing is removing branches from a fallen tree.
When limbing, leave larger limbs to support the
one cut as illustrated in Branches under
tension should be cut from the bottom up to
avoid binding the chain saw.
Before any cuts are started, pick your escape route
(or routes, in case the intended route is blocked).
Clear the immediate area around the tree and make
sure that there are no obstructions in you planned
paths of retreat. Clear a path of safe retreat approxi-
mately 135° from the planned line of fall. The retreat
path should extend back and diagonally to the rear
of the expected line of fall. See
a. Make the felling back cut at least 2 inches (50.8
mm) higher than the horizontal notching cut
Keep the felling back cut parallel to the
horizontal notching cut. Make the felling back
cut so that enough wood is left to act as a hinge.
The hinge wood keeps the tree from twisting and
falling in the wrong direction.
b. Do not cut through the hinge.
c. As the felling cut gets close to the hinge, the tree
should begin to fall. If there 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 back cut is complete
and use wedges of wood, plastic or aluminum to
open the cut and drop the tree along the desired
line of fall.
d. 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.
Bucking is cutting a log into lengths. It is important
is evenly distributed on both feet. When possible,
the log should be raised and supported by the
use of limbs, logs or chocks. Follow the simple
directions for easy cutting.
Begin on the top side of the log with the bottom of
the saw against the log; exert light pressure down-
ward. Note that the saw will tend to pull away from
you.
When the log is supported along its entire length,
it should be cut from the top (overbucking)
When the log is supported on only one end, cut
1/3 the diameter from the underside (underbuck-
When the log is supported on both ends, cut 1/3
of that diameter from the top overbuck. Then
Begin on the underside of the log with the top of the
saw against the log; exert light pressure upward.
During underbucking, the saw will tend to push back
at you. Be prepared for this reaction and hold the

When bucking on a slope, always stand on the
uphill side of the log (Fig. 25).
To maintain complete control when cutting
through, release the cutting pressure near the
end of the cut without relaxing the grip on the
chain saw handles. Don’t allow the chain to
contact the 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.
After each use, clean debris from the chain and
guide bar with a soft brush. Wipe the chain saw
surface with a clean cloth moistened with a mild
soap solution.
Remove the side cover, and then use a soft
brush to remove debris from the guide bar, saw
chain, sprocket and side cover.
Always clean out wood chips, saw dust, and dirt
from the guide bar groove when replacing the

a. A cold chain is correctly tensioned when there is
no slack on the underside of the guide bar and
the chain is snug, but it can be turned by hand
without binding. The chain must be re-tensioned
the bar groove.
b. During normal saw operation, the temperature
of the chain will increase. The drive links of a
correctly tensioned warm chain will hang approx-
imately 0.050 in. (1.3 mm) out of the bar groove
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
Never use a dull or damaged saw chain. A dull saw
chain cutter leads to increased physical strain, in-
creased vibration load, unsatisfactory cutting results
and increased wear.
For smooth and fast cutting, the chain needs to be
maintained properly. The chain requires sharpen-
ing when the wood chips are small and powdery,
the chain must be forced through the wood during
angles and to the same length, as fast cutting can be
obtained only when all cutters are uniform.

2. Properly tension the chain prior to sharpening.

to 0.035 in. (0.5 mm to 0.9 mm). Use a 0.025 in. (0.6
mm) depth-gauge jointer.
When the guide bar shows signs of wear, reverse it
on the saw to distribute the wear for maximum bar
life. 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
occur. A bar with any of the following faults should be
replaced.
Wear inside the bar rails which permits the 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. 36). Turn the
guide bar and check that the lubrication holes and
chain groove are free from impurities.
