SERVICE
23. Tool service must be performed only by
qualified repair personnel. Service or main-
tenance performed by unqualified personnel
could result in a risk of injury.
24. When servicing a tool, use only identical
replacement parts. Follow instructions in
the Maintenance section of this manual.
Use of unauthorized parts or failure to follow
Maintenance instructions may create a risk of
electric shock or injury.
USE PROPER EXTENSION CORD: Use only three-wire extension cords that have
three-prong grounding-type plugs and three-pole receptacles that accept the tool's
plug. Make sure your extension cord is in good condition. Replace or repair damaged
or worn cord immediately. 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. Table 1 shows the
correct size to use depending on cord length and nameplate ampere rating. If in
doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.
GROUNDING INSTRUCTIONS:
This tool should be grounded while in use to protect the operator from electric shock.
The tool is equipped with a three-conductor cord and three-prong grounding type
plug to fit the proper grounding type receptacle. The green (or green and yellow) con-
ductor in the cord is the grounding wire. Never connect the green (or green and yel-
low) wire to a live terminal. Your unit is for use on 120 volts and has a plug that looks
like Fig. “A”.
