Unit does not start
Engine out of gas
Fill engine with gas
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 drawn in

Remove the valves and clean then (-> refer to
Section 7.2/7.3) / replace worn parts
Pressure control valve
turned down completely
Turn the pressure control valve to the right

Check: Suction system tightened properly?
Cleaning connection (if available) at rigid
suction tube screwed tight and not leaking?
Inlet valve button leaky? -> Replace wiper and
O-ring (-> refer to Section 7.1)

generate pressure
Unit has sucked in air
Air in the oil circuit
Bleed the oil circuit in the unit by turning the
pressure control valve completely to the left
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).
Unit reached pressure,
but the pressure
collapses during
spraying.
Suction filter clogged
Check the suction filter. If necessary, clean/
replace
Paint cannot be worked
in this state. Due to its
properties the paint clogs
the valves (inlet valve)
and the delivery rate is
too low.
Dilute the paint
Unit reached pressure,
but the pressure
collapses during
spraying.
Clogged gun filter does
not let enough paint pass
Check/clean the (high-pressure filter) gun filter
Tip clogged
Clean the tip (-> refer to Section 4.6)

the max. pressure
possible. Paint
nevertheless exits at
the return hose.
