Keep Work Area Clean
Clutteredareas invite injuries. Do notstart cutting untilyou have a clear work
area, secure footing, and a planned retreat path from the falling tree.
Consider Work Area Environment
Use extreme caution when cutting small size brush and saplings because
the slender material may catch the saw chain and be whipped toward you
or pull you off balance. Do not operate a chain saw in a tree unless specifi-
cally trained todo so. When cutting a limb that isunder tension be alert for
spring back
so that you will not be struck when the tension in the wood
fibers is released. Don't expose chain saw to rain. Don't use chain saw in
damp or wet locations. Do not use chain saw in presence of flammable
liquids or gases.
Guard Against Electric Shock
Preventbody contact with grounded surfaces. For example: metalpipes, wire
fences.
Keep Children Away
Do not let visitors contact chain saw or extension cord. All visitors should
be kept away from work area.
Store Idle Chain Saw
When not in use, chain saws should be stored in a dry, and high or locked-
up place
- out of the reach of children. When storing saw, use a scabbard
or carrying case.
Don't Force Chain Saw
It will do the job better and safer at the rate for which it was intended.
Use Right
Tool
Cut wood only. Don't usechain saw for purpose not intended - for example
- Don't use chain saw for cutting plastic, masonry non-wood building
materials.
Dress Properly
Do notwear loose clothing or jewelry. They can get caught in movingparts.
Rubber gloves and non-skid footwear are recommended when working
outdoors. Wear protective hair covering to contain long hair.

9. Use Safety Glasses
Also use safety footwear; snug fitting clothing; protective gloves; hearing
and head protection.
Carry the chain saw by the front handle with the saw stopped, finger off
the switch, the guide bar and saw chain to the rear.
11. Maintain Chain Saw With Care
Inspect chain saw cords periodically and if damaged, have repaired by
authorized service facility. Keep cord clear
of the chain and operator at all
times. Never carry saw by the cord or pull it todisconnect from receptacle.
Keep cordfrom oil and sharp edges. Inspectextension cords periodically and
replace if damaged. Keep tools sharp and clean for better and safer perfor-
mance. Follow instructions for lubricating and changing accessories. Keep
handles dry, clean, and free from oil and grease.
Disconnectchainsaw when not
in use, beforeservicing, and when changing
accessories and attachments, such as saw chain and guard.
Use only extension cords intended for use outdoors and
so marked.
Watch what you are doing. Use common sense. Do not operate chain saw
when youare tired. Keepallparts of the bodyaway fromthe saw chainwhen
the motor is operating. Before you start the saw, make sure the saw chain
is not contacting anything.
Before further use of the chain saw, a guard or other part that isdamaged
should be carefully checked to determine that
it will operate properly and
perform itsintended function. Checkfor alignment of moving parts, binding
of movingparts, breakage of parts, mounting, andany other conditions that
may affect its operation. A guard or other part that is damaged should be
properly repaired or replaced by an authorized service center unless other-
wise indicatedelsewhere
in this instructionmanual. Havedefective switches
replaced by authorized service center. Do not use chain saw if switch does
notturn
it onand off. Donotoperate a chainsaw that is damaged, improperly
adjusted, or is not completely and securelyassembled. Be sure that the saw
chain stops moving when the trigger is released.
WARNING: 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 lightning fast reverse
reaction, kicking the guide bar upand back towards the operator. Pinching
the saw chain along the top of the guide bar may pushthe guide bar rapidly
back towards the operator. Either of these reactions may cause you tolose
control ofthe saw which could result
in seriousinjury to user. The following
precautions should be followed to minimize kickback.

WARNING:
0 Under normal circumstances, it should never be necessary to intentionally release the
chain brake while the tool is running. Occasionally, after the brake has been actuated,
the protector may not reset tothe exact originalposition. Ifthis happens, placethe tool
on
a flat surface in a clear area (away from other persons or objects that might contact
the saw chain). Then turn the tool on. After running the tool for
a couple of seconds,
turn the tool off. While the motor
is coasting, reset the protector with the same hand
you used toturn the tool on. Holdthe tool firmly by grasping the front handlewith the
other hand.
Careless handling of the tool
at this time could result in serious injury, therefore use
extreme caution when resettingthe chain brake inthis manner.
e Before operation, always check to see that the chain brake actuatesproperly.

Usingthe chain saw
Always be sure of your footing and hold the chain
saw firmly with both hands while the
motor is running.
Felling a tree
When bucking and felling operations are beingperformedby
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 beingfelled. Trees should notbe 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.
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.
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
as shown in Fig. 16.
Retreat
Direction
of fall
__ - -
Before felling is started, consider the natural lean of the tree, the location of larger
branches and the wind direction tojudge which way the tree will fall. Removedirt, stones,
loose bark, nails, staples, and wire from the tree where fellingcuts are to be made.
Notchingundercut
Make the notch 1/3 the diameter of the tree, perpendicular to the direction of fall as
shown in Fig. 17. Make the lower horizontal notching cut first. This will help to avoid
pinchingof either the saw chain or the guide bar when the second notch is beingmade.
13

Felling back cut
Make the felling back cut at least 2 inches
(50.8 mm)higher than the horizontal notch-
ing cut as shown in Fig. 17. Keep the fell-
ing 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.
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
as shown in Fig. 18. Branches under
tension should be cut from the bottom up
to avoid binding the chain saw.
I
Fig. 1
LIMB CUT
Keep work off ground
Leave support limbs until log is cut
1
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.
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.
14

Bucking a log
Bucking is cutting a logintolengths. It is importantto 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 the simple directions for easy
cutting.
When the log
is supported along its entire
length
as shown in Fig. 19, it is cut from
the top (overbuck).
When the log is supported on one end, as
shown in Fig. 20, cut 1/3 the diameter
from the underside (underbuck). Then
make the finished cut
by overbucking to
meet the first cut.
When the
log is supported on both ends, as
shown in Fig. 21, cut 1/3 of that diameter
from the top overbuck. Then make the
finished cut by underbuckingthe lower
2/3
tomeet the first cut.

complete control, release the cutting pres-
sure near the end of the cut without re-
laxing your grip on the chain saw handles.
Don't
let the chain contact the ground.
After completing the cut, wait for the saw
chain to stop before you move the chain

MAINTENANCE
CAUTION :
Always be sure that the tool is switched off and unpluggedbefore attempting toperform
inspection or maintenance.
Filling saw chain
To get the most in cutting performance from your tool, you must keep the cutter sharp
and filed properly
as shown below.

Fig. 2d
To file the saw chain, push the file in the
direction of the arrow. When pulling it
back, be careful not to touch the cutters
with the file.
Saw chain
File
After a saw chain has been filed two or three times, the “raker” (see Fig. 24) may need
to be filed down slightly. This is because the raker acts as a depth gauge for the cutters.
As the cutters are filed, they lose some height due totheir angled shape. Eventually, the
cutters will become lower than the depth gauge and consequently, will not be able to
cut.
To remedy this, use a flat file to file the tops of the rakers so that they are about
0.5 mm (0.025”) below the tips of the cutters (see Fig. 24). Be careful not to file the
rakers excessively or the cutters will be allowed to take too large of
a “bite”, causing
the tool to
stall or snag in the cut.

Removingchip buildup
Chips and sawdust will build up in the guide bar groove and oil hole, cloggingthem and
impairing oil flow. Removethe guide bar and clean them out.
