Malfunction Cause Remedy
The pump does not
prime.
Blockage in the suction side
(suction hose) / fitting
Remove the blockage.
Pump draws in air. Check the hose connection on the
suction hose for leakage.
No pumping power. Jammed or damaged ball
valves.
Replace the ball valves.
Pump draws in air, noticeable
air bubbles in the spraying
mixture container.
Check the hose connections on the
suction hose for leakage.
Wobbling of the spraying
cone
Irregular fluid flow from the
pump.
Check valves on suction and pres-
sure side, replace if necessary.
The required and en-
tered application quan-
tity is not reached.
High travel speed; low pump
drive speed
Reduce the travel speed and in-
crease the pump drive speed, until
both the error message and the
audible warning disappear.
The required and en-
tered application quan-
tity is not reached.
Blocked nozzles/nozzle filters Clean nozzles / nozzle filters with
compressed air For this purpose
unscrew the nozzles and blow them
out with a compressed air gun (on
the boom middle section). In case
of frequent appearance check the
pressure filter.
The permitted spraying
pressure range of the
installed spraying noz-
zles is not complied with.
The specified travel speed has
changed, which affects the
spraying pressure.
Change the travel speed to reach
the travel speed range that has been
determined for spraying operation.
The spraying pressure
cannot be regulated
downwards.
Spraying pressure too high Check the external control terminal;
switch of internal cleaning and induc-
tion hopper, if necessary.
The spraying pressure
does not maintain the
nominal value.
Spraying pressure too low - Close the quick filling valve.
- Cleaning the filter.
- Increase the engine speed.
