Important for filter maintenance:
Service only when unit is turned off and totally depressurized.
Check filter case, threads and O-rings and maintain or replace if necessary. It is recommended to
record the quantity of pressure cylinders filled in order to reassure that the precise replacement
intervals are kept. Leave the cartridge in the filter during idle periods. Leave unit at approximately
1000 – 600 psi//75 - 40 bar to prevent ambient humidity from penetrating into the compressor pipe
system.
4.8.7 Suction and pressure valves
Valves should be taken out and cleaned after 1,000 operating hours. The seats must be carefully
treated to prevent even the slightest damage. Use only gasoline, soft brushes of copper or nylon. Do
not use steel brushes, screwdrivers, etc. Should you detect even the smallest damage (ruptures, worn,
seats, etc.), replace the entire part. In order to service the valves, the valve heads must be removed.
4.8.8 Drive motors
Upon request: gasoline engine - 4 stroke; Diesel engine; Electric engine 7,5 HP.
For further details, see data sheet of manufacturer.
4.8.9 Mounting of cooler and belt guard
After approximately 50 operating hours, check fixation of cooler and retighten. Check distance between
rotating parts and guard so that smooth operating is guaranteed even after lengthening of the v-belt.
Maintenance schedule:
Prior to every cylinder filling:
- drain condensate (§4.8.5)
- check safety valve (§4.8.2)
- review filling procedures (§4.3)
- check oil level daily (§4.8.1)
- purification cartridge replacement intervals (§4.8.6)
