DOUBLE INSULATION
Double insulation is a concept in safety in electric power 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
tool’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 V, 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 outlet, double-check
the power supply.
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 product will draw. An
undersized cord will cause a drop in line voltage, resulting in
overheating and loss of power. Use the chart to determine
the minimum wire size required in an extension cord. Only
round jacketed cords listed by Underwriter’s Laboratories
(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 “WA” 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 personal injury.
WARNING:
Check extension cords before each use. If
damaged replace immediately. Never use the
product with a damaged cord since touching
the damaged area could cause electrical shock
resulting in serious injury.
