EXTENSION CORDS
When using a power tool at a considerable distance from
a power source, be sure to use an extension cord that has
the capacity to handle the current the tool will draw. An
undersized cord will cause a drop in line voltage, resulting
in overheating and loss of power. Use the chart to deter-
mine the minimum wire size required in an extension cord.
Only round jacketed cords listed by Underwriter’s Labora-
tories (UL) should be used.
When working outdoors with a product, use an extension
cord that is designed for outside use. This type of cord is
designated with “W-A” or “W” on the cord’s jacket.
Before using any extension cord, inspect it for loose or
exposed wires and cut or worn insulation.

**Used on 12 gauge - 20 amp circuit.
NOTE: AWG = American Wire Gauge
WARNING:
Keep the extension cord clear of the working area.
Position the cord so that it will not get caught on lumber,
tools, or other obstructions while you are working with
a power tool. Failure to do so can result in serious per-
sonal injury.
WARNING:
Check extension cords before each use. If damaged
replace immediately. Never use product with a damaged
cord since touching the damaged area could cause elec-
trical shock resulting in serious injury.
DOUBLE INSULATION
Double insulation is a concept in safety in electric pow-
er tools, which eliminates the need for the usual three-
wire grounded power cord. All exposed metal parts are
isolated from the internal metal motor components with
protecting insulation. Double insulated tools do not need
to be grounded.
WARNING:
The double insulated system is intended to protect the
user from shock resulting from a break in the product’s
internal insulation. Observe all normal safety precautions
to avoid electrical shock.
NOTE: Servicing of a product 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 product to your
nearest authorized service center for repair. Always use
original factory replacement parts when servicing.
ELECTRICAL CONNECTION
This product has a precision-built electric motor. It should
be connected to a
power supply that is 120 volts, AC
only (normal household current), 60 Hz. Do not operate
this product on direct current (DC). A substantial voltage
drop will cause a loss of power and the motor will overheat.
If the product does not operate when plugged into an out-
let, double-check the power supply.
