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:

Decreasing the depth gauge height
can lead to increased kickback.
14. Maintain labels and nameplates on the tool.
These carry important safety information.
If unreadable or missing, contact
Harbor Freight Tools for a replacement.
15. Avoid unintentional starting.
Prepare to begin work before turning on the tool.
16. 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.
17. This product is not a toy.
Keep it out of reach of children.
18. People with pacemakers should consult their
physician(s) before use. Electromagnetic fields in
close proximity to heart pacemaker could cause
pacemaker interference or pacemaker failure.
In addition, people with pacemakers should:
• Avoid operating alone.
• Do not use with Trigger locked on.
• Properly maintain and inspect to avoid
electrical shock.
• Properly ground power cord. Ground Fault Circuit
Interrupter (GFCI) should also be implemented
– it prevents sustained electrical shock.
19. 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.

1. Tools marked with “Grounding Required” have
a three wire cord and three prong grounding

1. Grounded tools require a three wire extension cord.
Double Insulated tools can use either
a two or three wire extension cord.
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. G2$$&R"C;$&BAH
3. The smaller the gauge number of the wire, the
greater the capacity of the cord. For example,
a 14 gauge cord can carry a higher current
than a 16 gauge cord. G2$$&R"C;$&BAH
4. When using more than one extension cord
to make up the total length, make sure
each cord contains at least the minimum
wire size required. G2$$&R"C;$&BAH
5. If you are using one extension cord for more
than one tool, add the nameplate&amperes
and use the sum to determine the required
minimum cord size. G2$$&R"C;$&BAH
6. If you are using an extension cord outdoors, make
sure it is marked with the suffix “W-A” (“W” in
Canada) to indicate it is acceptable for outdoor use.
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.
8. Protect the extension cords from sharp objects,
excessive heat, and damp or wet areas.

1. Front Handle Guard – A guard that protects your
hand on the Front Handle from the Saw Chain.
2. Switch Lockout – A movable stop that
prevents the unintentional operation of
the Trigger until manually activated.
3. Low-Kickback Chain – A Chain that complies
with the kickback performance requirements
of ANSI B175.1-1991 when tested on a
representative sample of chain saws.

The Chain Saw is supplied with the Chain Guide Bar and Saw Chain pre-installed and no assembly
is required. Before first use and before each use thereafter, check the Saw Chain tension.
X'4$J New Saw Chains often need to be tensioned several times during first use.
Check a new Saw Chain’s tension often when first using.
Follow the directions in the following sections for checking and adjusting Saw
Chain tension and for replacing the Saw Chain when necessary.

1. Before using, check the Saw Chain tension.
2. While wearing heavy-duty gloves, use your index
finger and thumb to carefully grab the Saw Chain
in the middle section under the Chain Guide Bar.
3. Pull the Saw Chain away from the Guide Bar.
4. The Saw Chain should snap back against
the Guide Bar. The Chain should fit snugly
in the groove of the Chain Guide Bar, yet
you should still be able to slide the chain
along the Chain Guide Bar by hand.
5. There should be no sagging between the Guide Bar
and Saw Chain on the underside of the Guide Bar. O7<:@$&!J&&D9$6]7(<&2"?&D9"7(&R$(#7'(

1. Remove the Nut Cover (46) and loosen
the Nut (28) on the Drive Cover (26).
2. Pull up on the Guide Bar Nose and hold it
up while making the tension adjustment.
3. Turn the Tension Screw (31) clockwise,
until the Saw Chain makes contact along
the bottom of the Chain Guide Bar.
Turn the Tension Screw 1/4 turn more.
4. Continue to hold the Guide Bar Nose
up while tightening the Nut.
5. Check the Saw Chain tension again following
steps 2 through 5 under Checking Saw Chain
Tension above. If needed, repeat the adjusting
steps to achieve the correct tension.
6. When adjustment is complete replace the Nut Cover.

1. Soak the new Saw Chain overnight in
Bar and Chain Oil (sold separately).
2. Remove the Nut Cover (46) and loosen the
Nut (28) on the Drive Cover (26), then loosen
the Tension Screw (31) counter-clockwise
until the Saw Chain (30) is loose.
3. Unthread the Nut and remove the Drive Cover.
4. Push the Chain Guide Bar (29) towards the
Sprocket (37) to further loosen the Saw Chain.
5. Remove the Saw Chain from
the Sprocket, then the Guide Bar.
X'4$J&Check the condition of the Sprocket when
replacing the chain. The Sprocket should be
replaced if it shows signs of wear or is damaged.
If needed, have the Sprocket replaced and the
bearings greased by a qualified technician.

X'4$J Check the condition of the Chain Guide Bar
when replacing the chain. Refer to Chain Guide Bar
Care on page 16.
6. Flip the Chain Guide Bar over before mounting

7. Place the new Saw Chain around the Sprocket
and over the Guide Bar. Make sure the Cutters
of the Saw Chain are facing away from the Chain
Saw along the top edge of the Guide Bar. Fit
the Chain in the groove around the Guide Bar.
8. Replace the Drive Cover.
X'4$J For proper placement the pin on the bottom
of the Drive Cover must fit into its hole on the Right
Housing (22) prior to securing the Nut. Do not force.
9. Finger tighten the Nut, then tension the
Saw Chain following the steps in Adjusting
Saw Chain Tension on page 9.
