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.
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.
20. DIRECTION OF FEED.
Feed work into a blade or cutter against the
direction of rotation of the blade or cutter only.
21. NEVER LEAVE TOOL RUNNING UNATTENDED.
TURN POWER OFF. Don’t leave tool
until it comes to a complete stop.

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. Grip workpiece as lightly as possible (while still
keeping safe control of it). 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.

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

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
