9. USE PROPER EXTENSION CORD. Make sure your
extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough to
carry the current your product will draw. An undersized
cord will cause a drop in line voltage resulting in loss
of power and overheating. Table A shows the correct
size to use depending on cord length and nameplate
ampere rating. If in doubt, use the next heavier gauge.
The smaller the gauge number, the heavier the cord.
10. WEAR PROPER APPAREL. Do not wear loose
clothing, gloves, neckties, rings, bracelets, or
other jewelry which may get caught in moving
parts. Nonslip footwear is recommended. Wear
protective hair covering to contain long hair.
21. NEVER LEAVE TOOL RUNNING UNATTENDED.
TURN POWER OFF. Don’t leave tool
until it comes to a complete stop.
Grounding Instructions
TO PREVENT ELECTRIC
SHOCK AND DEATH FROM
INCORRECT GROUNDING WIRE
CONNECTION
READ AND FOLLOW THESE
INSTRUCTIONS:
11. ALWAYS USE SAFETY GLASSES. Also use
face or dust mask if cutting operation is dusty.
Everyday eyeglasses only have impact resistant
lenses, they are NOT safety glasses.
12. SECURE WORK. Use clamps or a vise to hold
work when practical. It’s safer than using your
hand and it frees both hands to operate tool.
13. DON’T OVERREACH. Keep proper
footing and balance at all times.
14. MAINTAIN TOOLS WITH CARE. Keep tools sharp
and clean for best and safest performance. Follow
instructions for lubricating and changing accessories.
15. DISCONNECT TOOLS before servicing;
when changing accessories, such as
blades, bits, cutters, and the like.
16. REDUCE THE RISK OF UNINTENTIONAL STARTING.
Make sure switch is in off position before plugging in.
17. USE RECOMMENDED ACCESSORIES.
Consult the owner’s manual for recommended
accessories. The use of improper accessories
may cause risk of injury to persons.
18. NEVER STAND ON TOOL. Serious injury
could occur if the tool is tipped or if the
cutting tool is unintentionally contacted.
19. CHECK DAMAGED PARTS. Before further use of
the tool, a guard or other part that is damaged should
be carefully checked to determine that it will operate
properly and perform its intended function – check for
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.
110-120 V~ Double Insulated Tools:
Tools with Two Prong Plugs
Outlets for 2-Prong Plug
1. To reduce the risk of electric shock, double insulated
equipment has a polarized plug (one blade is wider
than the other). This plug will t in a polarized
outlet only one way. If the plug does not t fully in
the outlet, reverse the plug. If it still does not t,
contact a qualied electrician to install the proper
outlet. Do not change the plug in any way.
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.)
20. DIRECTION OF FEED. Feed work into
a blade or cutter against the direction of
rotation of the blade or cutter only.

22. 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 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 lter out microscopic particles.
(California Health & Safety Code § 25249.5, et seq.)
23. 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 § 25249.5, et seq.)
24. 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.
Grinding Wheel Safety Warnings
1. Do not use a grinding wheel if it is chipped,
cracked, or worn. Check if the wheel has cracks
not visible to the human eye by hanging it up by
the central hole and tapping it with a nonmetallic
object (such as a screwdriver handle). If it is in
good condition it will produce a metallic sound.
A dull sound indicates a crack or break.
2. Only use grinding wheels that t the Arbor (7/8”).
Do not try to change or modify the mounting hole
on a grinding wheel to make it t. Grinding wheel
replacements are available at Harbor Freight Tools.

4. Always test the Grinding Wheel by running it
for a minute prior to contact with a chain.
5. Keep away from the wheel when it is turning,
and make sure no one is standing close, in
the line of the wheel rotation trajectory.
6. If the grinding wheel vibrates, turn off the
machine immediately and check that it is
mounted securely, and that is not damaged.
7. Do not try to stop the grinding wheel with
your hands, even if you are wearing safety
gloves. The wheel will cut through gloves
and your hand, causing serious injury.
Vibration Safety
This tool vibrates during use. Repeated or
long-term exposure to vibration may cause
temporary or permanent physical injury,
particularly to the hands, arms and shoulders. To
reduce the risk of vibration-related injury:
1. Anyone using vibrating tools regularly or for an
extended period should rst 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 medical or physical symptoms related to
vibration (such as tingling, numbness, and white or
blue ngers), seek medical advice as soon as possible.
INSTRUCTIONS.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and ngers,
increasing the risk of vibration-related injury.
3. Wear suitable gloves to reduce the
vibration effects on the user.
4. Use tools with the lowest vibration when there
is a choice between different processes.
5. Include vibration-free periods each day of work.
6. Grip tool as lightly as possible (while still keeping
safe control of it). Let the tool do the work.
7. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately.
