Inspection, air supply circuit
The procedure below describes how to inspect the air supply circuit.
Note Action
If there is a lot of water in the filter recept-
acle, this is a sign that the supplied air
consist of too much water. Check if there is water in the filter recept-
acle.
Normally the filter receptacle is drained
automatically in case of a fall of air pressure.
If there is no fall of pressure in the air sys-
tem, there is an automatic draining of the
system, when the water level reaches a
certain level. 1
If this is the case, steps must be taken to
correct this problem!
Drain the air filter receptacle manually by
pressing a small pin at the bottom of the air
filter unit. 2
Retighten if necessary! Make a check that there is no leakage. 3
If needed replace the air filter. Make a check of the condition of the air filter. 4
Normally the filter should be replaced
after one year of use.
