Use proper extension cords. 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. Fig. 3, shows the correct gauge to use
depending on the cord length. If in doubt, use the next
heavier gauge. The smaller the gauge number, the
heavier the cord.

2. Grounded, cord-connected tools intended for use on a
supply circuit having a nominal rating less than 150 volts:
This tool is intended for use on a circuit that has an outlet that
looks like the one illustrated in Fig. 1. The tool has a grounding
plug that looks like the plug illustrated in Fig. 1
. A temporary
adapter, which looks like the adapter illustrated in Fig. 2, may
be used to connect this plug to a matching 2-conductor recep-
tacle as shown in Fig. 2 if a properly grounded outlet is not
available. The temporary adapter should be used only until a
properly grounded outlet can be installed by a qualified elec-
trician. The green-colored rigid ear, lug, and the like, extending
from the adapter must be connected to a permanent ground
such as a properly grounded outlet box. Whenever the adapter
is used, it must be held in place with a metal screw.
NOTE: In Canada, the use of a temporary adapter is not
permitted by the Canadian Electric Code.
WARNING: IN ALL CASES, MAKE CERTAIN THE
RECEPTACLE IN QUESTION IS PROPERLY

QUALIFIED ELECTRICIAN CHECK THE RECEPTACLE.
1. All grounded, cord-connected tools:
In the event of a malfunction or breakdown, grounding pro-
vides 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 risk of electric shock. The conductor with insu-
lation 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 neces-
sary, 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
type plugs and matching 3-conductor receptacles that accept
the tool’s plug, as shown in Fig. 1.
Repair or replace damaged or worn cord immediately
