• KNOW YOUR POWER TOOL. Read the operator's

manual carefully. Learn the saw's applications and limi-

tations as well as the specific potential hazards related

to this tool.

• GUARD AGAINST ELECTRICAL SHOCK BY PRE-

VENTING BODY CONTACT WITH GROUNDED

refrigerator enclosures.

• KEEP GUARDS IN PLACE and in good working

order. Never operate the tool with any guard or cover

benches invite accidents. DO NOT leave tools or

pieces of wood on the saw while it is in operation.

• AVOID DANGEROUS ENVIRONMENTS. Don't use

power tools in damp or wet locations or expose to rain.

Keep the work area well lit.

extension cord while operating.

• MAKE WORKSHOP CHILDPROOF with padlocks and

• 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 overheat-

ing. A wire gage size (A.W.G.) of at least 14 is recom-

mended for an extension cord 25 feet or less in length.

If in doubt, use the next heavier gage. The smaller the

gage number, the heavier the cord.

• DRESS PROPERLY. Do not wear loose clothing,

resistant lenses, they are NOT safety glasses.

• SECURE WORK. Use clamps or a vise to hold work

when practical. It's safer than using your hand and

frees both hands to operate tool.

that may affect its operation. A guard or other part that

is damaged must be properly repaired or replaced by

an authorized service center to avoid risk of personal

injury.

• USE THE RIGHT DIRECTION OF FEED. Feed work

into a blade or cutter against the direction of rotation of

blade or cutter only.

• NEVER LEAVE TOOL RUNNING UNATTENDED.

TURN THE POWER OFF. Don't leave tool until it
