2.6.1 Before each maintenance
task
1. Switch on the compressor at the ON/OFF
switch (item 13). Disconnect the power
supply.
2. Interrupt the power supply to the main
switch.
3. Depressurise the whole compressor:
open ball valves at condensate drainage
points 1 to 3 (items 10 to 12) slowly.
Close the ball valves when the air flow
stops.
2.6.2 Cleaning the compressor
• Clean the cooling fins on the cylinder, cyl-
inder head and aftercooler using com-
pressed air.
• Clean the fan impeller cover on the motor.
2.6.3 Draining condensate from
pressure vessel
Condensate is a water pollutant. Dispose
of it according to applicable regulations!
1. Place a suitable vessel under the conden-
sate drain.
2. To drain condensate, the pressure may
be no more than 2 bar.
3. Open ball valves 1 to 3 (items 10 to 12).
4. Close the ball valves when the flow of
condensate stops.

After each use Drain condensate from pressure vessel
Commissioning Check the oil level, add oil if necessary.
Check screw connections
Weekly Check intake filter
After 6 months Check V-belt tension (where applicable)
Clean intake filter

After 1 year Change oil (mineral oil)
Change intake filter
Change check valve and insert
Check screw connections
After 2 years Change oil (synthetic oil)
Change V-belts (where applicable)
After 5 years Change safety valve
2.6.4 Checking the oil level
For compressors with an oil dipstick, pull the
dipstick out.
1. The oil level must be between the top
and bottom marks (oil dipstick/oil in-
spection glass). (Figure 4a)
2. Correct if necessary.
In very unfavourable conditions, condensate
may find its way into the oil. This can be
identified by milky oil. In this case, the oil
must be changed immediately.
2.6.5 Changing/adding oil
1. Allow the compressor to warm up, switch
it off, disconnect the power supply.
2. Pull out the oil filler plug or oil dipstick
(item 03), hold the used oil container un-
der the oil filler plug (item 04), screw
open the oil drain screw, drain used oil
completely.
3. Screw the oil drain screw closed.
4. Add the prescribed quantity of oil.
5. Check the oil level, correct if necessary.
Insert the oil filler plug or oil dipstick.
6. Dispose of used oil according to applica-
ble regulations.
As the mineral oil, we recommend Art. No.
B111002, synthetic oil Art. No. B111006.
Using incorrect oils shall void the warran-
ty.
