Liquid System
Self-Cleaning Filter - Choice of Restrictor
It is important to have a large flow through the filter. This is achieved by
choosing the restrictor size in relation to the liquid consumption of the
spray boom. 4 restrictors are supplied. Use the green one with largest
orifice (A) first.
Remove the hose (N) from the filter. Be careful not to loosen the seal.
Place the restrictor in the hose and mount the hose again.
If the required working pressure cannot be obtained, the restrictor is too
large. Choose a smaller restrictor. Start with a black one, then a white and
finally a red one.
When cleaning the filter, remove the hose (N) and the hose at the safety
valve and check that there are no residues.
Standard filter size is 80 mesh. Filters of 50 and 100 mesh are available
and can be changed by opening the filter top.
Check the condition of the O-rings before reassembly and replace them
if damaged.
Pulsation Damper
The air pressure in the pulsation damper is factory preset at 2 bar to cover spray working pressures between 3 and 15 bar.
When using spray pressures outside this range, the air pressure should be adjusted as shown in the diagram. The diagram
is embossed on the damper.
