Indicating lamp illumi-
nates
Unit fuse has triggered Let the motor cool down
Unit does not suck in Air bubbles do not exit
at the return hose
Inlet valve clogged Press the inlet valve button until the stop is
reached several times by hand
Inlet/outlet valve soiled
/ foreign bodies (e.g.
threads) drawn in / worn
Remove the valves and clean then (-> refer to
Section Pkt.10.2/10.3) / replace worn parts
Pressure control valve
turned down completely
Turn the pressure control valve to the right un-
til the stop is reached
Air bubbles exit from
the return hose
Unit is sucking in outside
air
Check: Inlet valve button leaky? -> Replace
wiper and O-ring (-> refer to Section 10.1)
The red entry is missing in the coating mate-
rial entrance (-> see 4.3)

min. Then turn the pressure control valve to
the right and set the pressure (repeat process
several times, if necessary).
Not enough oil Check the oil level
Pressure collapses dur-
ing work (this can be
seen on the pressure
gauge)
Suction lter clogged Check the suction lter. If necessary, clean, re-
place or remove
Paint cannot be worked in
this state. Due to its prop-
erties the paint clogs the
valves (inlet valve) and the
delivery rate is too low.
Dilute the paint
Unit reached pressure,
but the pressure col-
lapses during spraying.
pressure gage still
shows high pressure
Clogged lter do not let
enough paint pass
Check/clean the gun lter
Tip clogged Clean the tip (-> refer to Section 10.1)
