POSSIBLE CAUSE
Green indicating lamp No voltage applied

Unit fuse has triggered
Green indicating lamp Supply voltage wa inter-
lights up rupted
Air bubbles exit from Unit is sucking in outside
the return hose air
Air bubbles do not exit Inlet valve clogged
at the return hose
Inlet/outlet valve soiled

threads) drawn in / worn
Pressure control valve

sure, but the pressure
collapses, also at the
manometer, during
spraying.
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.
Unit reached pressure, Clogged filter do not let
but the pressure col- enough paint pass
lapses during spraying.
Manometer still shows
high pressure
Tip clogged
Unit does not generate Relief valve defective

MEASURES FOR ELIMINATING THE MALFUNCTION
Check voltage supply
Let the motor cool down until the indicating
lamp lights up
Switch the multifunction switch to 0 (OFF)
and switch the unit back on -> Unit does not
switch back on automatically
Check: Suction system tightened properly?
Cleaning connection at rigid suction tube

button leaky? -> Replace wiper and O-ring (->
refer to Section 12.1)
Press the inlet valve button until the stop is
reached several times by hand
Remove the valves and clean then (-> refer to
Section Pkt.12.2/12.3) / replace worn parts
Turn the pressure control valve to the right un-
til the stop is reached
Bleed the oil circuit in the unit by turning the
pressure control valve completely to the left
(until overturning) and let it run approx. 2
control valve completely to the left (until over-
turning) and let it run approx. 2 – 3 min. Then
turn the pressure control valve to the right
and set the spraying pressure (repeat process
several times, if necessary). Process is assisted
by positioning the unit vertically.
Check the suction filter. If necessary, clean/
replace
Dilute the paint
Check/clean the high-pressure filter, gun filter
Clean the tip (-> refer to Section 10.1)
Clean or replace the relief valve (-> refer to
Section 12.5)
