Clean the auxiliary pressure filter as needed.
Lower the parallelogram for this purpose. Turn
the yellow lever to the right (2) by 90° to thus
block the flow to the pressure filter. Open the
small yellow valve at the lift (3) and collect any
draining agent. Dispose of the agent if necessary
or return it to the spraying mixture container.
Open the filter housing with the pressure filter
wrench. Clean the auxiliary pressure filter.
Repeat all steps in the opposite order after
cleaning.

entering into the spraying mixture container
during filling through the dome. The screen has

Drain filter in the tank
The drain filter in the tank prevents settled
agents from being deposited in the suction fitting.
Suction filter
The suction filter filters the water / chemical
before it enters into the centrifugal pump (mesh
size 0.9 mm).
