ELECTRICAL CONNECTIONS

Power Source

A separate electrical circuit should be used for your tool. This circuit should not be less than #12
wire and should be protected with a 20 amp fuse. Before connecting the motor to the power line,
make sure the switch is in the "OFF" position and be sure the electric current is of the same charac-
teristics as indicated on the tool. All line connections should make good contact. Running on low
voltage will damage the motor.

Extension Cords

Figure 1
Make sure your extension cord is in good condition and
is a 3-wire extension cord which has a 3-prong grounding
type plug and matching receptacle which will accept the
tool's plug. When using an extension cord, be sure to
use one heavy enough to carry the current of the tool.
An undersized cord will cause a drop in line voltage,
resulting in loss of power and overheating. Extension
cords should be no longer than 50 ft.
WARNING: DO NOT EXPOSE THE TOOL TO RAIN OR OPERATE IN DAMP LOCATIONS.

Grounding Instructions

WARNING: THIS TOOL MUST BE GROUNDED WHILE IN USE TO PROTECT THE
OPERATOR FROM ELECTRIC SHOCK.
All grounded, cord-connected tools:
In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric
shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a
grounding plug. The plug must be plugged into a matching outlet that is properly installed and
grounded in accordance with all local codes and ordinances. Do not modify the plug provided - if it
will not fit the outlet, have the proper outlet installed by a qualified electrician.
Improper connection of the equipment-grounding conductor can result in risk of electric shock. The
conductor with insulation having an outer surface that is green with or without yellow stripes is the
equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do
not connect the equipment grounding conductor to a live terminal. Check with a qualified electrician
or service personnel if the grounding instructions are not completely understood, or if in doubt as to
whether the tool is properly grounded.
Figure 2
Grounded, cord-connected tools intended for
use on a supply circuit having a nominal rating
less than 150 volts will have a grounding plug
similar to illustration.
WARNING:
IN ALL CASES, MAKE SURE THE RECEPTACLE IN QUESTION IS PROPERLY GROUNDED.
