To reduce the risk of electrical hazards, fire
hazards or damage to the compressor, use
proper circuit protection. Your compressor
is wired at the factory for operation using
the voltage shown. Connect the compressor
to a power source with the correct breaker
size.
Adequate wiring and motor protection
should be provided for all stationary
compressors. Wiring used for other
machinery should not be used. A
qualified electrician familiar with local
electrical codes in your area should be
used. Size supply wiring per NEC (National
Electric Code) requirements.

General Information
STARTING THE COMPRESSOR
Prior to actually running the compressor,
check the following items:
Crankcase oil - Make sure the sight glass
shows ½ full or slightly above.
Make sure all rags, tools, oil, etc. are away
from the unit.
Open the air system to free it of any pressure.
Switch the compressor on for a few
revolutions to make sure the rotation is
correct. Correct rotation is clockwise
when facing the sight glass on the pump.
Operate the compressor for a few minutes
unloaded (air system open) then allow the
compressor to pump up. Make sure the
electrical pressure switch properly switches
off the compressor according to the setting
desired. (130 psi for Single Stage, 165 for
216V, and 175 psi for all other Two Stage.)
Make sure the pressure in the tank does
not exceed its rating. Single Stage should
operate at a maximum of 130 psi, 216V
should operate at a maximum of 165 psi,
& Two Stage at a maximum of 175 psi. If
the pressure gauge indicates a pressure that
is higher than these maximum pressures,
shut off compressor immediately and call
1-800-528-5192.
Electrical connections must be properly
grounded. Ground connections should be
connected at the grounding screw.
Overheating, short circuiting and fire damage
will result from inadequate wiring.
