3.9.2 Pump oil
The pump is supplied with a Castrol ALPHASYN T iso 150 oil. When replenishing use only this
type of oil.
URGENT: PROTECT NATURE
Waste oil and oil sludge should be removed or destroyed in accordance with local rules and
regulations.
3.9.3 Water filter
There are two filters on the water inlets in order to prevent impurities from entering the high-pres-
sure pumps and thus causing damage. The filters should be cleaned regularly. The frequency
depends on the purity of the inlet water, but daily cleaning would often be required.
Cleaning is accomplished by leaving both inlets open and opening the outlet cocks on filters
(14). The inlet water will then flush away impurities from the filters.
3.9.4 Couplings
In order to prevent leakages and destruction of quick-couplings on hoses, spray handle, outlet
points and spray lances it is urgent to clean them regularly and grease with a little oil or fat.
