ELECTRICAL REQUIREMENTS
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.
BEFORE CONNECTING THE MACHINE TO THE POWER SOURCE, VERIFY THAT THE VOLTAGE OF YOUR POWER SUPPLY CORRE-
SPONDS 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 QUAL-
IFIED 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.
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 recepta-
cle that accepts the tool’s plug. Repair or replace a
damaged 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.
