ELECTRRCAL CONNECTION

Be sure your power supply agrees with the nameplate
marking. 120 Volts, 60 Hz or '_,C only" means your tool
must be operated only with alternating current and NEVER
with direct current. A voltage decrease of more than 10%
will cause loss of power and overheating All Sears tools
are factory tested; if this tool does not operate, check the
power supply

DOUBLE=INSULATION

improved insulation system isfor added protection against
injury resulting from a possible electrical insulation failure

within the tool.
This tool is intended for residential use only.

CAUTION: When servicing Double-Insulated Tools,
USE ONLY IDENTICAL REPLACEMENT PARTS. Replace

or repair damaged cords.

NOTE: The lower the wire size number, the heavier the
wire, and the farther it will carry current without a

significant voltage drop.

EXTENSION CORDS

When using the tool at a considerable distance from the
power source, an extension cord of adequate size must
be used for safety, and to prevent loss of power and

overheating Use the table below to determine minimum
wire size required.

Before using cords, inspect them for loose or exposed
wires and damaged insulation.. Make any needed repairs
or replacement before using your power tool.
