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

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)
Unit does not generate
the max. pressure
possible. Paint
nevertheless exits at
the return hose.
Relief valve defective
