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, 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.
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.

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.

Grounding
TO PREVENT ELECTRIC SHOCK AND
DEATH FROM INCORRECT
GROUNDING WIRE CONNECTION READ AND
FOLLOW THESE INSTRUCTIONS:
110-120 VAC
1. In the event of a malfunction or breakdown,
grounding provides a path of least resistance for
electric current to reduce the risk of electric shock.
This tool is equipped with an electric cord having an
equipment-grounding conductor and a grounding
plug. The plug must be plugged into a matching
outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
2. Do not modify the plug provided – if it will
not fit the outlet, have the proper outlet
installed by a qualified electrician.
3. Improper connection of the equipment-grounding
conductor can result in a risk of electric shock.
The conductor with insulation having an outer
surface that is green with or without yellow
stripes is the equipment-grounding conductor.
If repair or replacement of the electric cord or
plug is necessary, do not connect the equipment-
grounding conductor to a live terminal.
4. Check with a qualified electrician or service
personnel if the grounding instructions are
not completely understood, or if in doubt as
to whether the tool is properly grounded.
5. Use only 3-wire extension cords that
have 3-prong grounding plugs and 3-pole
receptacles that accept the tool’s plug.
6. Repair or replace damaged or worn cord immediately.
Grounding
Pin
125 VAC 3-Prong Plug and Outlet
(for up to 125 VAC and up to 15 A)
7. This tool is intended for use on a circuit that has
an outlet that looks like the one illustrated above in
125 VAC 3-Prong Plug and Outlet. The tool has
a grounding plug that looks like the plug illustrated
above in 125 VAC 3-Prong Plug and Outlet.
8. The outlet must be properly installed and grounded
in accordance with all codes and ordinances.
9. Do not use an adapter to connect
this tool to a different outlet.
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 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 medical or
physical symptoms related to vibration (such as
tingling, numbness, and white or blue fingers),
seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
3. Use tools with the lowest vibration when there
is a choice between different processes.
4. Include vibration-free periods each day of work.
5. Let the tool do the work.
6. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately.

LIMITED 90 DAYS WARRANTY
Harbor Freight Tools Co. makes every effort to assure that its products meet high quality and durability standards,
and warrants to the original purchaser that this product is free from defects in materials and workmanship for the
period of 90 days from the date of purchase. This warranty does not apply to damage due directly or indirectly,
to misuse, abuse, negligence or accidents, repairs or alterations outside our facilities, criminal activity, improper
installation, normal wear and tear, or to lack of maintenance. We shall in no event be liable for death, injuries
to persons or property, or for incidental, contingent, special or consequential damages arising from the use of
our product. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the
above limitation of exclusion may not apply to you. THIS WARRANTY IS EXPRESSLY IN LIEU OF ALL OTHER
WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE WARRANTIES OF MERCHANTABILITY AND FITNESS.
To take advantage of this warranty, the product or part must be returned to us with transportation charges
prepaid. Proof of purchase date and an explanation of the complaint must accompany the merchandise.
If our inspection verifies the defect, we will either repair or replace the product at our election or we may
elect to refund the purchase price if we cannot readily and quickly provide you with a replacement. We will
return repaired products at our expense, but if we determine there is no defect, or that the defect resulted
from causes not within the scope of our warranty, then you must bear the cost of returning the product.
This warranty gives you specific legal rights and you may also have other rights which vary from state to state.
