2.6.1 Before each maintenance
task
1. Swtich on the compressor at the ON/OFF
switch (item 10). Disconnect the power
supply.
2. Depressurise the compressor: using the
blow gun, blow out all pressure from the
vessel.
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 Clean the filter pressure re-
ducer insert
1. Depressurise the vessel of the filter pres-
sure reducer.
2. Hold a suitable vessel under the conden-
sate drain. Drain condensate.
3. Remove the vessel of the filter pressure
reducer. Unscrew the mounting screw of
the filter insert by screwing anticlockwise
(Figure 4a).
4. Remove the filter insert, clean in soapy
water (max. 50 °C).
5. Installation is in reverse order.

2.6.4 Draining condensate from
filter pressure reducer
Draining semi-automatically: Rotate the
condensate drain valve 1/4 turn anticlock-
wise. Under 1 bar: condensate drains. (Fig-
ure 4a)
Draining manually: Rotate the condensate
drain valve clockwise and push it up. Con-
densate drains.
2.6.5 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 the
(item 09): rotate 1 1/2 turns anticlock-
wise.
4. Rotate the condensate drain valve clock-
wise to block it.

2.6.6 Checking the oil level

For compressors with an oil dipstick, pull the
dipstick out.
