maintenanCe
Before doing any maintenance or adjustments to your air compressor,
the following safety precautions should be taken:
installation & operation
►
TURN OFF AND LOCK OUT ELECTRIC POWER.
►
DRAIN AIR RECEIVER AND AIR LINES OF AIR PRESSURE.
CheCKing belt tension (if belt driven)
Adjust belt(s) so when pressure is applied at the center, there is approxi-
mately 1/2” slack (see diagram “Figure A” below).
Centre distance
too loose
too tight
slight bow
Correct tension
If the belt is in-
stalled too tight,
the motor might be
overloaded. This
will cause the mo-
tor to overheat. If
the belt is installed
too loosely, it will
slip and excessive
wear and vibration
will occur.
1)
Disconnect power supply.
2)
Remove belt guard.
)
Loosen motor bolts and slide motor toward compressor head just
enough to allow old belt to be removed.
4)
Install proper replacement belt.
5)
Slide motor away from compressor head to provide recommend-
ed tension as shown in diagram (Figure A.)
6)
Align belt using a straight edge ruler against pulley’s edge.
)
Fasten motor bolts.
8)
Ensure motor and compressor pulley’s are secure. Re-check
alignment.
9)
Re-install belt guard and reconnect power supply.
10)
Belt tension should be checked after 20 hours of operation.
Check tension monthly thereafter.
