ELECTRICAL REQUIREMENTS
Before connecting the machine to the power source, verify that the voltage of your power supply corresponds with
the voltage specified on the motor I.D. nameplate. A power source with greater voltage than needed can result in
serious injury to the user as well as damage to the machine. If in doubt, contact a qualified electrician before con-
necting to the power source.
This tool is for indoor use only. Do not expose to rain or use in wet or damp locations.
GROUNDING INSTRUCTIONS
In the event of an electrical malfunction or short circuit, grounding
reduces the risk of electric shock. The motor of this machine is wired
for 120V single phase operation and is equipped with a 3-conduc-
tor cord and a 3-prong grounded plug to fit a grounded type
receptacle, A.
Do not remove the 3rd prong (grounding pin) to make it fit into an
old 2-hole wall socket. If an adaptor plug is used, B, it must be
attached to the metal screw of the receptacle.
Note: The use of an adaptor plug is illegal in some areas. Check your
local codes.
DO NOT MODIFY THE PLUG PROVIDED.
If it will not fit your receptacle, have the proper receptacle installed by a qualified electrician.
CHECK with a qualified electrician or service person if you do not completely understand these grounding instruc-
tions, or if you are not sure the tool is properly grounded.
EXTENSION CORDS
USE ONLY 3-WIRE EXTENSION CORDS THAT HAVE 3-PRONG GROUNDING PLUGS AND 3-POLE RECEPTACLES THAT ACCEPT
THE TOOLS' PLUG. REPAIR OR REPLACE A DAMAGED OR WORN POWER CORD OR PLUG IMMEDIATELY.
If you find it necessary to use an extension cord with your machine make sure the cord rating is suitable for the
amperage listed on the motor I.D. plate. An undersized cord will cause a drop in line voltage resulting in loss of
power and overheating. The accompanying chart shows the correct size extension cord to be used based on cord
length and motor I.D. plate amp rating. If in doubt, use the next heavier gauge. The smaller the number the heav-
ier the gauge.
