MAINTENANCE PROGRAMME
Before doing any job inside the machine, unless there are commands that require the machine to be switched on see chapter 3.3:
“Machine off status”.
Every day the user is recommended to check (before starting the compressor) the following:
a) Check the oil level (if necessary top up with the same type of oil through the oil filler cap).
b) Check the internal condition of the compressor for leakages.
c) Clean the prefilters.
With the compressor running:
d) Check the “SET” and “RESET” pressure on the display, the minimum pressure on the pressure gauge of the separator tank
(the pressure reading must be between 1 and 2.5 Bar) and the operating temperature on the display.
After 2000 hours (BLOCK “A”)
After 4000 hours (BLOCK “A”)
After 6000 hours (BLOCK “B”)
After 8000 hours (BLOCK “B”)
N.B. In particularly harsh environmental conditions, the maintenance intervals must be halved. After 8000 working hours it is
necessary to contact the Power System technical service
Change the air filter cartridge.
Change or clean the panel for pre-filtering the cooling air.
Change the oil (if using mineral oil, e.g. POWERFLUID 2000).
Change the oil filter cartridge.
Check the tightness of all the electrical connections (on the panel and on the motor terminal board).
Check the pressure drop in the oil separating filter, the difference between the value read on the pressure gauge of the separator and
that on the display. The value must not exceed 1 Bar.
Check the state of the transmission flexible coupling (if present).
Clean the air-oil radiator.
Change the air filter cartridge
Change the air-oil separator cartridge.
Change the oil (if using special oil POWERFLUID 2000 or 4000).
Change the oil filter cartridge.
Change or clean the panel for pre-filtering the cooling air.
Check correct operation of the safety valves, of the electrical components, and ensure the temperature probe is working.
Check the tightness of all the electrical connections (on the panel and on the motor terminal board).
Check the pressure drop in the oil separating filter, the difference between the value read on the pressure gauge of the separator and
that on the display. The value must not exceed 1 Bar.
Check the state of the transmission flexible coupling (if present).
