TABLE A

DON’T OVERREACH. Keep proper 13.
footing and balance at all times.

MAINTAIN TOOLS WITH CARE. Keep 14.
tools sharp and clean for best and safest
performance. Follow instructions for
lubricating and changing accessories.

DISCONNECT TOOLS before servicing; 15.
when changing accessories, such as
blades, bits, cutters, and the like.

REDUCE THE RISK OF 16.
UNINTENTIONAL STARTING. Make
sure switch is in off position before
plugging in.

USE PROPER EXTENSION CORD. 9.
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.

WEAR PROPER APPAREL. Do not wear 10.
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.

ALWAYS USE SAFETY GLASSES. Also 11.
use face or dust mask if cutting operation
is dusty. Everyday eyeglasses only have
impact resistant lenses, they are NOT
safety glasses.

SECURE WORK. Use vise to hold work 12.
when practical. It’s safer than using your
hand and it frees both hands to operate
tool.

USE RECOMMENDED ACCESSORIES. 17.
Consult the owner’s manual for
recommended accessories. The use of
improper accessories may cause risk of
injury to persons.

NEVER STAND ON TOOL. Serious 18.
injury could occur if the tool is tipped
or if the cutting tool is unintentionally
contacted.

CHECK DAMAGED PARTS. Before 19.
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.

DIRECTION OF FEED. Feed work into 20.
a blade or cutter against the direction of
rotation of the blade or cutter only.

NEVER LEAVE TOOL RUNNING 21.
UNATTENDED. TURN POWER OFF.
Don’t leave tool until it comes to a
complete stop.

WARNING: Some dust created by power 23.
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

and shoulders. To reduce the risk of
vibration-related injury:

Anyone using vibrating tools regularly 1.

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.
Do not smoke during use. Nicotine 2.

reduces the blood supply to the hands

and ngers, increasing the risk of

vibration-related injury.

WARNING: Handling the cord on this 24.
