CHECK with a licensed electrician or service personnel if you
do not completely understand the grounding instructions or
whether the tool is properly grounded.
USE ONLY THREE-WIRE EXTENSION CORDS that have
three-pronged plugs and outlets that accept the tool's plug as
shown in Fig. A. Repair or replace a damaged or worn cord
immediately.
CAUTION:
In all cases, make certain the outlet in question is
properly grounded. If you are not sure, have a licensed electrician check the outlet.
WARNING:
This tool is for indoor use only. Do not expose to rain or use in damp
locations.
Guidelines for using extension cords
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
a drop in line voltage resulting in loss of power and overheating. The table below shows the
correct size to be used according to cord length and nameplate ampere rating. When in doubt, use
the next heavier gauge. The smaller the gauge number, the heavier the cord.

Not Recommended
Make sure your extension cord is properly wired and in good condition. Always replace a
damaged extension cord or have it repaired by a qualified person before using it.
Protect your extension cords from sharp objects, excessive heat and damp/wet areas.
Use a separate electrical circuit for your tools. This circuit must not be less than a #12 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 rated the same as the
current stamped on the motor nameplate. Running at a lower voltage will damage the motor.
WARNING:
This tool must be grounded while in use to protect the operator from
electric shock.
