3.
Replace the oil drain plug (W) and tighten securely
4.
Slowly add compressor oil until it reaches the middle of the
sight glass (X). NOTE: When filling the crankcase, the oil flows
very slowly into the pump. If the oil is added too quickly, it will
overflow and appear to be full.
CAUTION: Overfilling with oil will cause premature compressor
failure. Do not overfill.
5.
Replace oil fill plug (Y) and tighten securely.
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 before
tightening motor mounting screws.
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 3/16" (4.8mm)
at midway between
the pulley and the
flywheel when a 5
pound (2.26 kg.) weight is applied at the midway point.
4.
When proper belt tension is achieved, tighten 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 Motor Pulley/Flywheel -
Alignment.
