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.

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 near-
est 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.
