Observe the specifications for compressed
air tools/units.
2.5.3 After use
1. Switch off the petrol engine (see petrol
engine instruction manual) and allow the
compressor to cool.
2. Disconnect the plug nipple of the com-
pressed air hose from the quick-action
coupling.
3. Clean the compressor if necessary (see
Chap. 2.6.2).
4. Depressurise the compressor (see Chap.
2.6.1).
5. Transport the compressor to the storage
location (see Chap. 2.4.1).
2.6 Maintenance
2.6.1 Before each maintenance task
1. Switch off the petrol engine (see petrol
engine instruction manual) and allow the
compressor to cool.
2. Depressurise the compressor: using the
blow gun, blow out all pressure from the
vessel.
3. Detach the ignition cable from the spark
plug.
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 FDM insert
1. Depressurise vessel of FDM.
2. Hold a suitable vessel under the conden-
sate drain. Drain condensate.
3. Disassemble vessel of FDM. Unscrew the
mounting screw of the filter insert by
screwing anticlockwise (Fig. 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 FDM
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.
