Important compressor usage points:
1. Switch compressor on and off at pressure switch only.
2. Drain air receiver daily.
3. Check oil daily.
4. Clean and check air intake filter weekly.
5. Service every 500 working hours.
6. Do not use extension lead or double adapter on single phase units.
7. On Three phase units, it is advisable to screw the electrical wires straight onto an isolator
and do not use a welding plug. Welding plugs may cause a loose connection.
8. If compressor struggles to start, it is due to insufficient power supply/ Voltage drop.
9. Do not operate from a generator without checking with Airpower first.
Piston compressor
service intervals: Every 500 working hours
During every service the following needs to be done/checked:
1. Replace oil (
make sure that the correct oil is used
).
2. Replace V Belt pulleys if worn
3. Check and adjust V belts. Replace if worn. Press as hard as you can with thumb (10 kg), in
centre between pulleys on V Belt. It must deflect about the belt thickness.
4. Check, clean or replace intake air filter element.
5. Clean intake air filter housing.
6. Check and repair if dust is entering system.
7. Check and tighten all loose bolts.
8. Check and repair belt guard.
9. Clean cooling fins.
10. Check non-return valve (
If non-return valve seat is worn out or damaged air will leak
continuous from bottom of pressure switch, when compressor switches off
)
11. Check for any oil and air leaks and repair.
12. Check safety valve (
Very important
). Adjust pressure switch and run manually 0.25 bar over
pressure. If safety valve does not blow, replace or repair safety valve.
Do not exceed normal
working pressure of air receiver as indicated on name plate.
Adjust pressure switch back to
normal after test.
13. Check pressure switch.
14. Check starter and overload setting. Overload must be set at motor full load amps, at correct
Hz.
15. Check gauges.
16. Ensure machine is safe.
17. Check when last a pressure test was done. In South Africa factories need a test every 3 years
and mines every year. Notify user if test is due.
