Problem
D The compressor
starts up briefly
when the switch-on
pressure is reached
or hums,
switches off auto-
matically.
E Compressor
continuously.
F During operation,
compressed
escapes via
load-relieving valve.
G After the switch-off
pressure is reached,
compressed
escapes via
load-relieving valve
until switch-on
pressure is reached
H Compressor
switches on
quently.
I Safety valve blows
out.
J Compressor over-
heats.
K Oil-lubricated com-

level rises without
oil having
added.

than permitted or the cross
section is too small.

Remedy
Check connection cable length
and cable cross-section
Chap. 2.4.4)
Clean or replace intake filter.
Check the air consumption of the
tools. Contact the service partner
Locate leak, contact service part-
ner.
Drain the condensate
Chap. 2.6.5).
Check compressed air line, plug
leak.
Close or replace.
Clean or replace load-relieving
valve.
Clean or replace the check valve
insert (see Chap. 2.6.11).
Replace check valve.
Drain the condensate
Chap. 2.6.5).
See item E
Have the pressure switch reset/
replaced by a qualified person.
Replace safety valve or contact
service partner.
Ensure sufficient ventilation.
Clean cooling fins on cylinder
(cylinder head).
Switch off compressor.
Compressor is too large, contact
service partner.
Change oil.
