IMPORTANT SAFETY INSTRUCTIONS
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 your product does
not operate when plugged into an outlet, double-check the power supply.
GFCI
Ground Fault Circuit Interrupter (GFCI) protection should be provided on the circuit(s) or outlet(s) to be
used for the product. Receptacles are available having built-in GFCI protection and may be used for
this measure of safety.
GUIDELINES FOR USING EXTENSION CORDS
USE THE PROPER EXTENSION CORD. 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 overheating. The table below shows the correct size to use depending
on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the
gauge number, the heavier the cord.

Make sure your extension cord is properly wired and in good electrical condition. Always replace a
damaged extension cord or have it repaired by a qualied person before use. Keep extension cords
away from sharp objects, excessive heat and damp or wet areas.
Use a separate electrical circuit for your tools. This circuit should comprise at least a 12 gauge wire
and should be protected with a 15 A time-delayed fuse. Before connecting the motor to the power line,
make sure the switch is in the OFF position and the electric current is identical to that stamped on the
motor nameplate. Running at a lower voltage will damage the motor.
SAVE THESE INSTRUCTIONS.
ALTHOUGH THIS TOOL IS DOUBLE INSULATED, THE EXTENSION CORD AND RECEPTACLE
MUST STILL BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM ELECTRICAL
SHOCK.
