6.0 MAINTENANCE
Before carrying out any maintenance jobs it is obligatory to stop the
machine and disconnect it from the power mains.
1
After the first 50 operating hours and then every 250 operating hours the oil
should be refreshed. Therefore, turn out the oil draintap (17) and also remove
the desaeration motor case/oil refill cap (11). Collect the oil. If the oil does not
come out any longer, turn in the oil draintap (17) and fill with fresh oil through
the desaeration motor case/oil refill cap (11) up to the red dot on the oil level
glass (8).
Always respect the regulations in force for disposing of old oil!
2
Regularly drain condensation water. The draintap is situated at the bottom of
the tank. Draining with pressure in the tank is the easiest way.
Condensate must be disposed of in conformity with the local regulations
in force (not in the sewer!).
As an alternative you can place an oil/water separator.
3
The oil level should also be checked regularly. The oil level must be on the red
dot on the oil level glass (8). If necessary refill with AIRPRESS compressor oil
through the desaeration motor case/oil refill cap (11).
Checking daily can prevent a lot of troubles!
Use oil of the same type as that already in the machine; do not mix
different types of oil!
4
The air filter element should be cleaned or changed regularly. This change
depends on the amount of fouling and should be done more often in dusty
situations and less often in a clean situation. For cleaning the filterelement, take
out the filtercontainer with the filter. Then clean the filter by blowing off the dust.
5
The V-belt should be checked after every 1000 hours. At the right tension, the
V-belt can easily be turned 45 degrees by hand.
If tension is too high, strong corrosion will occur or eventually the spindle of
motor or pump may break. At too little tension, the efficiency of the compressor
decreases considerably.
Tightening the V-belt goes as follows:
Dismount the belt protector (3).
Unscrew the fastening bolts on the motor sledge.
Remove the V-belt. Place the motor at the wright distance from the pump.
