2.6.8 Check screw fittings
1. Check all screw connections for tight fit
and retighten if necessary.
2. Observe the tightening torques (tighten-
ing torques calculated according to VDI
2230).
2.6.9 Clean intake filter
See Part 1 of the Instruction Manual.
L
Do not purge the intake opening. No for-
eign objects may enter.
Never operate the compressor without an
intake filter.
2.6.10 Checking, adjusting the V-
belt tension
V-belt driven compressors:
1. Switch off the petrol engine.
2. Remove the mounting plugs, take off the
belt guard grating.
Checking V-belt tension:
Press down on the V-belt at the top using
your thumb, halfway between the V-belt
discs. The belt should not give more the
width of the V-belt (Figure 8a).
Adjusting V-belt tension:
1. Mark the position of the petrol motor on
the base plate.
2. Unscrew the mounting screws of the mo-
tor (Figure 8b).
3. Move the motor towards the compressor
unit. Take off the V-belt.
4. Push the motor approx. 2 mm parallel
past the mark. Tighten the mounting
screws.
5. Fit the V-belt over the small V-belt disc
first, then stretch it over the large V-belt
disc.
6. Check the V-belt tension and repeat the
process if necessary.
7. Attach the belt guard grating using the
mounting plugs.
2.6.11 Replacing the safety valve
1. Detach the safety valve (item 11) by un-
screwing it anticlockwise.
2. Screw the new safety valve into place by
screwing it clockwise.
2.7 Decommissioning
Observe the safety instructions!
2.7.1 Preservation
Preservation of oil-lubricated compressors is
necessary if the compressor is taken out of
service for a long period (over 6 months) or
is new from the factory and will not be oper-
ated until much later.
1. Switch off the petrol engine. Detach the
ignition cable from the spark plug.
2. Allow the oil to drain. See Chap. 2.6.7.
3. Fill corrosion inhibiting oil (viscosity SAE
30). Insert the oil filler plug or oil dip-
stick.
4. Allow the compressor to warm up, switch
it off.
5. Refit intake filter, seal watertight with
Scotch tape.
6. Switch off the compressor. Disconnect
the power supply.
7. Drain condensate.
8. Depressurise the compressor.
Store the compressor in a dry location and
do not expose to large temperature fluctua-
tions.
2.7.2 Disposal
Dispose of the unit and packaging materials
according to applicable regulations.
