Belt Replacement
WARNING
: This unit starts automatically. ALWAYS shut off
and unplug the compressor, and bleed all pressure from the
system before servicing the compressor, and when the
compressor is not in use. Do not use the unit with the shrouds
or belt guard removed. Serious injury could occur from contact
with moving parts. Hot surfaces. Risk of burn. Pump head, and
surrounding parts are very hot, do not touch (see the Hot
Surfaces identified in Fig. 1). Allow compressor to cool prior to
servicing.
1. Set the Auto/Off lever to “OFF (O)”, unplug the unit, and relieve
all air pressure from the air tank.
2. Remove the outer belt guard (Z).
3. Mark motor position on saddle.
4. Loosen the motor mounting
screws and slide the motor
toward the air compressor pump.
5. Remove the belt and replace
with a new one.
6. See the

Adjusting Belt Tension
1. Slide motor into original position, line the motor up with the
mark made earlier on saddle.
2. Tighten two outside motor mounting screws enough to hold
the motor in place for checking pulley and flywheel alignment.
3. The belt should
deflect 1/4" (6.5 mm)
at midway between
the pulley and the
flywheel when a 10
pound (4.5 kg.) weight
is applied at the mid-
way point.
4. When proper belt ten-
sion is achieved, tight-
en motor mounting
screws. Torque to
20-25 ft-lbs (27.1-33.9 Nm.)
NOTE:
Once the motor pulley has been moved from its factory set
location, the grooves of the flywheel and pulley must be aligned to
within 1/16" (1.6 mm) to prevent excessive belt wear. Verify the
alignment by performing the following
