5. Replace belt guard.
Pulley and Fly wheel - Alignment
The air compressor fl ywheel and
engine pulley must be in-line (in
the same plane) within 1/16" to
assure belt retention within fl ywheel
belt grooves. To check align ment,
perform the fol low ing steps:
1. Disconnect the spark plug wire
on the engine and release all air
tank pressure.
2. Remove belt guard.
3. Place a straightedge against
the outside of the fl ywheel and
the engine drive pulley. Refer to
Figure as required.
4. Measure the distance between
the edge of the belt and the
straightedge at points A1 and A2
in Figure. The difference between
mea sure ments should be no
more than 1/16".
5. If the difference is greater or less
than 1/16", loosen the setscrew
holding the engine drive pulley to
the shaft and adjust the pulley's
position on the shaft until the A1
and A2 mea sure ments are within
1/16" of each other.
6. Tighten the engine drive pulley
setscrew to 70-80 in.-lbs.
7. Visually inspect the engine
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, loos en
the setscrew of the engine drive
pulley and equal ize B1 and B2,
using care not to disturb the belt
align ment per formed in step 2.
8. Retighten the engine drive pulley
set screw to 70-80 in.-lbs.
9. Reinstall belt guard.
10. Reconnect spark plug wire to
spark plug on engine.
STORAGE
Before you store the air compressor,
make sure you do the following:
1. Review the "Maintenance"
section on the preceding
pages and perform scheduled
maintenance as necessary.
2. Review the "Engine
Manufacturer's Operating and
Maintenance Instructions".
3. Remove the air tool or accessory.
4. Pull ring on safety valve allowing
air to bleed from the tank until
tank pressure is approximately 20
psi. Release safety valve ring.
5. Drain water from air tank by
opening drain valve on bottom of
tank.
Water will
condense in the air
tank. If not drained, water will
corrode and weaken the air tank
causing a risk of air tank rupture.
6. After the water has been drained,
close the drain or drain valve.
NOTE: If drain valve is plugged,
release all air pressure. The valve
can then be removed, cleaned, then
reinstalled.
7. Wind air hose around hose wrap
and secure in place.
Store the air compressor in a clean
and dry location.
