CycloneFilter
With the CycloneFilter, any impurities in the spray liquid will be cleaned
out and returned to the MainTank via the return flow.

Boost valve
The boost valve (5) has three positions marked with small dots on the
lever:
A.
This position is marked with 1 dot:
There is no return flow. This position is used when rinsing the
boom, if there is spray liquid in the MainTank. Also used when high
spraying volume is required.
B.
This position is marked with 2 dots:
Normal position when spraying. With return flow to prevent filter from clogging during spraying. This position is used
when rinsing the boom, if the MainTank is empty.
C.
This position is marked with 3 dots:
Flushing position which is used if the filter is clogged. Lift and hold the lever to use this position, which largely increases
return flow and flushes the filter. The pressure SmartValve must be set for “Spraying”.
μ
ATTENTION! Use of position C is no guarantee for a clean filter. Always do a visual inspection and cleaning of the filter.
For more about cleaning, see the section “10 Hours Service - CycloneFilter” on page 142.

DANGER! Never open the CycloneFilter unless the suction valve is
closed and the pressure SmartValve is set to “MainTank”.
Otherwise spraying liquid may hit you, when opening the filter,
and this will also drain the MainTank!
