Faults
WARNING
Danger of crushing, shearing, cutting, cutting off, being caught, winding up, being pulled
in and impact caused by
¾
accidental lowering of lifted, unsecured machine parts.
¾
accidental starting and rolling of the machine.
Secure the machine against unintended starting and accidental rolling away, before faults on the
machine are rectified. Wait until the machine has come to a halt before entering the danger zone.
Fault 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.
•
Drain valve on suction filter open.
•
Suction filter housing leaking.
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
Clogged nozzles / nozzle filter
or suction filter / pressure filter
Reduce the travel speed and in-
crease the pump drive speed until
both the error message and the
audible warning disappear.
Clean nozzles / nozzle filters with
compressed air. For this purpose
unscrew the nozzles and blow them
out with a compressed air gun (on
the folding boom middle section). In
case of frequent appearance check
the suction filter / pressure filter.
The permitted spraying
pressure range of the in-
stalled spraying nozzles
is not complied with.
Changed specified travel
speed which affects the spray -
ing pressure.
Change the travel speed to reach
the travel speed range again that
has been determined for spraying
operation.
The spraying pressure
does not maintain the
nominal value.
Spraying pressure too low
•
Clean the filter.
•
Increase the engine speed.
Main cleaning process
