Grounding Instructions
WARNING: If the machine does not come
wired to run, the electricals and motor
wiring must be done by a qualified
electrician. The machine must be properly
grounded to help avoid electrical shock and
possible death. Follow the recommendations
made by the National Electrical Code for
grounding.
1. All grounded, cord connected tools:
In the event of a malfunction or breakdown,
grounding provides a path of least resistance for
electric current to reduce the risk of 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 a 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.
Use only 3-wire extension cords that have 3-
prong grounding plugs and 3-pole receptacles
that accept the tool’s plug.
Repair or replace damaged or worn cord
immediately.
2. Grounded, cord-connected tools intended for
use on a supply circuit having a nominal rating
between 150-250 volts, inclusive:
This tool is intended for use on a circuit that has
an outlet that looks like the one illustrated in
Sketch D Fig. 3. The tool has a grounding plug
that looks like the plug illustrated in Sketch D.
Make sure the tool is connected to an outlet
having the same configuration as the plug. No
adapter is available or should be used with this
tool. If the tool must be reconnected for use on a
different type of electric circuit, the reconnection
should be made by qualified service personnel
and after reconnection, the tool should comply
with all local codes and ordinances.
Extension Cords
Use 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 a drop in
line voltage resulting in loss of power and
overheating. Fig. 4 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
