6 - Maintenance
6.3
The suction filter is located on the left side of the sprayer near the
pump. Its primary purpose is to protect the pump from damage. It
contains an automatic shut off valve to allow the operator to clean
and service the filter with a full tank.
Turn the yellow handle counter-clockwise until it “pops out”. This
closes an internal valve to prevent the main tank from draining
when cleaning the filter. Unscrew the large plastic nut and remove
the lid. Remove the filter for cleaning, being very careful not to dam-
age the O-ring of the filter lid. This would allow air to enter during
suction and cause rattling of hoses and continual pressure varia-
tions. To prevent this, it is advisable to lubricate the O-ring with veg-
etable oil before closing the lid. Finally, replace the yellow valve han-
dle and lock into position to allow flow through the filter.

Regular maintenance
WARNING! The suction filter is one of the most important elements of the fluid circuit. The ability of the pump to
take in air correctly largely depends on how well the filter has been cleaned and maintained. It is necessary to
clean the filter after every working day in order to keep the filter free of blockage.
Unscrew the filter bowl to inspect and clean the filter. When
reassembling, the O-ring should be lubricated with vegetable oil.
Alternative filter meshes are available. See section on Technical spec-
ifications - Filters and nozzles.
