ELECTRICAL REQUIREMENTS
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 120 V single phase operation
and is equipped with a 3-conductor cord and a 3-prong
grounding plug
A
to fit a grounded type receptacle
B
.
Do not remove the 3rd prong (grounding pin) to make
it fit into an old 2-hole wall socket or extension cord. If
an adaptor plug is used
C
, 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. If you have any doubts
or if the supplied plug does not correspond to your
electrical outlet, consult a qualified electrician before
proceeding.
CIRCUIT CAPACITY
Make sure that the wires in your circuit are capable of handling the amperage draw from your machine, as well
as any other machines that could be operating on the same circuit.
If you are unsure, consult a qualified electrician. If the circuit breaker trips or the fuse blows regularly, your machine
may be operating on a circuit that is close to its amperage draw capacity. However, if an unusual amperage
draw does not exist and a power failure still occurs, contact a qualified technician or our service department.
EXTENSION CORDS
If you find it necessary to use an extension cord with your machine, use only 3-wire extension cords that have
3-prong grounding plug and a matching 3-pole receptacle that accepts the tool’s plug. Repair or replace a dam-
aged extension cord or plug immediately. 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.

BEFORE CONNECTING THE MACHINE TO THE POWER SOURCE, VERIFY THAT THE VOLTAGE OF YOUR POWER SUP-
PLY 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.
THIS TOOL IS FOR INDOOR USE ONLY. DO NOT EXPOSE TO RAIN OR USE IN WET OR DAMP LOCATIONS.
