TRICIAN CHECK THE RECEPTACLE.
This tool is intended for use on a circuit that has an outlet
and a plug that looks like the one shown in Fig. 30. A
temporary adapter, which looks like the adapter illustrated
in Fig. 31, may be used to connect this plug to a 2-pole
recept acle, as shown in Fig. 31, if a properly grounded
outlet is not available. The temporary adapter should be
used only until a properly grounded outlet can be in-
st alled by a qualified electrician. THIS ADAPTER IS
N O T APPLICABLE IN CANADA. 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, as shown in Fig. 31.
GROUNDING INSTRUCTIONS
CAUTION: THIS TO O L MUST BE GROUNDED WHILE IN USE
TO PROTECT THE OPERATO R FROMELECTRIC SHOCK.
In the event of a malfunction or breakdown, grounding
provides a p ath of least resist ance for electric
current to reduce the risk of electric shock. The motor 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
inst alled 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 inst alled by a qualified electrician.
Improper connection of the equipment-grounding conduc -
tor 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 conduc -
tor. If rep air or replacement of the electric cord or plug is
necessary, do not connect the equipment grounding con -
ductor 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 recept acles that accept
the tool s plug, as shown in Fig. 30.
R e p air or replace damaged or worn cord immediately.

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-hole
recept acle 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 band saw. An undersized cord will
cause a drop in line volt age resulting in loss of power and
overheating. Fig. 32 shows the correct size to use de-
pending on cord length. If in doubt, use the next heavier
gage. The smaller the gage number, the heavier the cord.
