three-wire grounded power cord. All exposed metal

parts are isolated from internal metal motor

components with protecting insulation. Double

insulated tools do not need to be grounded.

IMPORTANT

Servicing of a tool with double insulation requires
extreme care and knowledge of the system and
should be performed only by a qualified service
technician. For service we suggest you return the tool
to your nearest Sears Store for repair. Always use

original factory replacement parts when servicing.

AVOID DANGEROUS ENVIRONMENT. Don't

use power tools in damp or wet locations or

visitors should wear safety glasses and be kept a

safe distance from work area. Do not let visitors

contact tool or extension cord.
STORE IDLE TOOLS. When not in use, tools

should be stored in a dry and high or locked-up
place - out of the reach of children.

and safer at the rate for which it was designed.

USE RIGHT TOOL. Don't force small tool or
attachment to do the job of a heavy duty tool.

Don't use tool for purpose not intended - for
example - A circular saw should never be used
for cutting tree limbs or logs.

protection during extended periods of operation.

DON'T ABUSE CORD. Never carry tool by cord

or yank it to disconnect from receptacle. Keep
cord from heat, oil, and sharp edges.

• SECURE WORK. Use clamps or a vise to hold
work. It's safer than using your hand and it frees

both hands to operate tool.

balance at all times. Do not use while standing
on a ladder or unstable support. Secure tools

AVOID ACCIDENTAL STARTING. Don't carry
plugged-in tool with finger on switch. Be sure

switch is off when plugging in.
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. A wire gage size

(A.W.G.) of at least 14 is recommended for an •

extension cord 100 feet or less in length. A cord
exceeding 100 feet is not recommended. If in

doubt, use the next heavier gage. The smaller •
the gage number, the heavier the cord.

suitable for use outdoors. Outdoor approved

cords are marked with the suffix W-A, for ex-

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

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 re-

placed by an authorized service center.
