EXTENSION CORDS
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 a 3-pole 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
grinder. An undersized cord will cause a drop in line voltage,
resulting in loss of power and over-heating. Fig. 7A shows the
correct gage to use depending on the cord length. If in doubt,
use the next heavier gage. The smaller the gage number, the
heavier the cord.

GROUNDING INSTRUCTIONS
CAUTION: THIS TOOL MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR
FROM ELECTRIC SHOCK.
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 out-
let, have the proper outlet installed by a qualified elec-
trician.
Improper connection of the equipment-grounding con-
ductor can result in risk of electric shock. The conduc-
tor with insulation having an outer surface that is green
with or without yellow stripes is the equipment-ground-
ing con-
ductor. 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 under-
stood, 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 3-hole receptacles that accept
the tool's plug, as shown in Fig. 8.
Repair or replace damaged or worn cord immediately.
This tool is intended for use on a circuit that has an outlet
and a plug that looks like the one shown in Fig. 8.
A temporary adapter, which looks like the adapter illustrat-
ed in Fig. 9, may be used to connect this plug to a
2-pole receptacle, as shown in Fig. 9, 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 electrician. THIS ADAPTER IS NOT
APPLICABLE IN CANADA. The green-colored rigid ear,
lug, and the like, extending from the adapter must be con-
nected to a permanent ground, such as a properly
grounded outlet box, as shown in Fig. 9.
CAUTION: IN ALL CASES, MAKE CERTAIN THE RECEP-
TACLE IN QUESTION IS PROPERLY GROUNDED. IF
YOU ARE NOT SURE, HAVE A CERTIFIED ELECTRI-
CIAN CHECK THE RECEPTACLE.
