chain stops moving when the trigger
is released.
13. disconnect chain saw.
Disconnect chain saw when not
in use, before servicing, and
when changing accessories and
attachments, such as saw chain and
guard.
16. guard against kickback.
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 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 injury to user.
14. stay alert.
a. Watch what you are doing. Use
common sense. Do not operate
chain saw when you are tired.
b. Keep all parts of the body away from
the saw chain when the motor is
operating.
c. Before you start the saw, make
sure the saw chain is not contacting
anything.
the following precautions should
be followed to minimize kickback:
15. check damaged parts.
a. Grip Saw firmly.
a. Before further use of the chain
saw, a guard or other part that

alignment of moving parts, binding
of moving parts, breakage of parts,
mounting, and any 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
otherwise indicated elsewhere in this
instruction manual.
b. Do not over reach.
c. Keep proper footing and balance at
all times.
d. Don’t let the nose of the guide bar
contact a log, branch, ground or
other obstruction.
e. Don’t cut above shoulder height.
f. Use devices such as low kickback
chain, guide bar nose guards and
special guide bars that reduce the
risks associated with kickback.
b. Have defective switches replaced by
authorized service center.
c. Do not use chain saw if switch does
not turn it off.

• Crystalline silica from bricks and
cement or other masonry products
• 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. (California Health & Safety
Code § 25249.5, et seq.)
consult their physician(s) for advice.
19. Do not touch guide bar tip to any
object. Tip contact may cause
guide bar to move suddenly
upward and backwards.

20. Use only identical Oregon Chain
and Bar replacement components.
21. Maintain labels and nameplates on
the tool. These carry important safety
information. If unreadable or missing,
contact Harbor Freight Tools for a
replacement.
27. WARNING: Handling the cord on
this product will expose you to lead,
a chemical known to the State of
California to cause cancer, and
birth defects or other reproductive
harm. Wash hands after handling.
(California Health & Safety Code §

22. Avoid unintentional starting. Prepare
to begin work before turning on the
tool.
23. Do not lay the tool down until it has
come to a complete stop. Moving
parts can grab the surface and pull
the tool out of your control.
28. The warnings, precautions,
and instructions discussed in
this instruction manual cannot
cover all possible conditions and
situations that may occur. It must
be understood by the operator that
common sense and caution are
factors which cannot be built into this
product, but must be supplied by the
operator.
24. Do not leave the tool unattended
when it is plugged into an electrical
outlet. Turn off the tool, and unplug
it from its electrical outlet before
leaving.

1. Anyone using vibrating tools regularly
or for an extended period should
first be examined by a doctor and
then have regular medical check-
ups to ensure medical problems are
not being caused or worsened from
use. Pregnant women or people
who have impaired blood circulation
to the hand, past hand injuries,
nervous system disorders, diabetes,
or Raynaud’s Disease should not use
this tool. If you feel any symptoms
related to vibration (such as tingling,
numbness, and white or blue fingers),
seek medical advice as soon as
possible.
Check with a qualified
electrician if you are in doubt
as to whether the outlet is
properly grounded. do not
modify the power cord plug
provided with the tool. never
remove the grounding prong
from the plug. do not use the
tool if the power cord or plug
is damaged. if damaged, have
it repaired by a service facility
before use. if the plug will not
fit the outlet, have a proper
outlet installed by a qualified
electrician.
2. Do not smoke during use. Nicotine
reduces the blood supply to the
hands and fingers, increasing the risk
of vibration-related injury.
double insulated tools: tools
with two prong plugs
3. Wear suitable gloves to reduce the
vibration effects on the user.
4. Use tools with the lowest vibration
when there is a choice.
5. Include vibration-free periods each
day of work.
6. Grip tool as lightly as possible (while
still keeping safe control of it). Let

7. Make sure the extension cord is
properly wired and in good electrical
condition. Always replace a damaged
extension cord or have it repaired by
a qualified electrician before using it.
2. Double insulated tools may be used
in either of the 120 volt outlets shown
in the preceding illustration. (see
Outlets for 2-prong plug.)
8. Protect the extension cords from
sharp objects, excessive heat, and
damp or wet areas.
extension cords
9. Use extension cords with at least a
gauge wire as large as indicated in
table a for 7.1 to 12.0 Amperes.
1. Grounded tools require a three wire
extension cord. Double Insulated
tools can use either a two or three
wire extension cord.
10. Keep the cord away from the cutting
area. Position the cord so that it will
not be caught on branches, and the
like, during cutting.
2. As the distance from the supply
outlet increases, you must use a
heavier gauge extension cord. Using
extension cords with inadequately
sized wire causes a serious drop in
voltage, resulting in loss of power and
possible tool damage.

downward pressure against the
bottom mid-section of the Saw Chain

at its own rate. Applying too much
pressure can damage the tool.

2. 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.
1. When felling a tree, make sure the
tree is not felled in a manner that
would endanger any person, strike
any utility line, or cause any property
damage. 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. The Chain Saw
operator should keep on the uphill
side of the terrain, as the tree will
likely roll or slide downhill after it is
felled.
3. Remove dirt, stones, loose bark,
nails, staples, wire, and other foreign
objects from the tree where the cuts
are to be made.

horizontal notching cut first. This
will help to avoid pinching of either
the Saw Chain or the Chain Guide
Bar when the second notch is being
made.

5. When making a felling back cut,
make the felling back cut at least
2 inches 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. Do not cut through
the hinge.

from a fallen tree, leave the 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 Saw Chain.
6. 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 (72), 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.
bucking
9. Bucking a log is cutting a log into
lengths. It is important to 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, chocks or a timberjack.
7. When the tree begins to fall, remove
the Chain Saw from the cut. Turn
off the Chain Saw and put it down.
Then, use the retreat path planned.
Be alert for overhead limbs falling,
and watch your footing.

When “cutting through”, to maintain
complete control release the cutting
pressure near the end of the cut
without relaxing your grip on the
Chain Saw Handles. Do not allow
the Saw Chain (72) to contact the
