Air Filter Inspection and
Replacement
Hot surfaces. Risk
of burn.
Compressor heads are exposed
when filter cover is removed.
Allow compressor to cool prior to
servicing.
A dirty air filter will not allow the
compressor to operate at full
capacity. Keep the air filter clean at
all times.
1. Remove
the air filter
cover.
2. Remove
the air filter
from filter
Air Filter
cover.
Cover
IMPORTANT:
Do not operate the compressor with
the air filter removed.
3. Place new air filter into filter
cover. Refer to the "Repair Parts"
for the correct part number.
4. Replace air filter cover and lock
into place.
Motor Pulley/Flywheel Alignment
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" to prevent excessive belt wear.
The air compressor flywheel and motor
pulley must be in-line (in the same
plane) within 1/16" to assure belt
retention within flywheel belt grooves.
To check alignment, perform the
following steps:
1. Unplug air compressor from
power source.
2. Remove belt guard.
3. Place a straightedge against the
outside of the flywheel and the
motor drive pulley.
4. Measure the distance between the
edge of the belt and the
straightedge at points A1 and A2
in figure. The difference between
measurements should be no more
than 1/16".
5. If the difference is greater or less
than 1/16" loosen the set screw
holding the motor drive pulley to
the shaft and adjust the pulley's
position on the shaft until the A1
and A2 measurements are within
1/16" of each other.
6. Torque the motor drive pulley set
screw to 70-80 in.-lbs.
7. Visually inspect the motor drive
pulley to verify that it is
perpendicular to the drive motor
shaft. Points B1 and B2 in figure
above should appear to be
equal. If they are not, loosen the
setscrew of the motor drive
pulley and equalize B1 and B2,
using care not to disturb the belt
alignment performed in step 4.
8. Retighten the motor drive pulley
set screw to 70-80 in.-lbs.
9. Reinstall belt guard.
Air Compressor Pump Intake
and Exhaust Valves
Once a year have a Trained Service
Technician check the air compressor
pump intake and exhaust valves.
Inspect Air Lines and Fittings
for Leaks
1. Turn the air compressor on to
inspect for air leaks.
2. Apply a soap solution to all air
line fittings and
connections/piping. Bubbles will
indicate a leak.
3. Correct any leaks found.
IMPORTANT: Even minor leaks can
cause the air compressor to
overwork, resulting in premature
breakdown or inadequate
performance.
