General 15-220, Setup And Operation Manual

GROUNDING INSTRUCTIONS

In the event of an electrical malfunction or short circuit,
grounding reduces the risk of electric shock to. This
motor of this machine is wired for 110V single phase
operation and is equipped with a 3-conductor cord
and a 3-prong grounded plug to fit a grounded type
socket. Do not remove the the 3rd prong (grounding
pin) to make it fit into an old 2-hole wall socket. If an
adaptor plug is used it must be attached to the metal
screw of the socket. The wall socket must be properly
installed and grounded. Note: The use of an adaptor
plug is illegal in some areas. Check you local codes.

DO NOT MODIFY THE PLUG PROVIDED.

If it will not fit your receptacle, have the proper recep-
tacle installed by a qualified electrician.

CHECK 

with a qualified electrician or service person if

you do not completely understand these grounding
instructions, or if you are not sure the tool is properly
grounded.

ELECTRICAL REQUIREMENTS

Before connecting the machine to the power source, ver-
ify 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 connecting to the power source.

EXTENSION CORDS

USE ONLY 3-WIRE EXTENSION CORDS THAT HAVE 3-PRONG GROUNDING PLUGS AND 3-POLE RECEPTACLES THAT
ACCEPT THE TOOL’S PLUG. REPAIR OR REPLACE DAMAGED OR WORN CORD 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 
heavier the gauge.

In all cases, make certain the receptacle is pro-
perly grounded. If you are not sure, have a quali-
fied electrician check the receptacle.

This tool is for indoor use only. Do not expose to
rain or use in damp locations.

This tool must be grounded while in use to protect
the operator from electrical shock.
