Air Filter inspection and
Replacement
Risk of Burns,
Compressor head
and cyminder smeeve are very hot,
Do not touch. AHow compressor to
cool prior to servicing.
A dirty air filter will not allow the
compressor to operate at fall
capacity. Keep the air filter clean at
all times.
1. Remove the air filter cover.
2. Remove the air filter from filter
COV@K
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
NOTE: Once the motor pulley has
been moved from its factory set
location, the grooves of the flywheel
and puIIey 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 Iess
than 1/16" loosen the set screw
holding the motor drive pulley to
the shaft and adjust the patIey'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.qbs.
7. Visually inspect the motor
drive pulley to verify that it is
perpendicular to the drive motor
shaft. Points B1 and B2 of Figure
should appear to be equal. If
they are not, loosen the setscrew
of the motor drive putIey and
equalize B1 and B2, using care
not to disturb the belt alignment
performed in step 2.
8. Retighten the motor drive paIley
setscrew to 70-80 in.qbs.
9. Reinstall belt guard.
