ATTENTION! A special valve with white flap (2A) is used at the
two upperside inlets. It has to be placed in the valve ope-
nings as shown. All others are the type with black flap. It is
recommended to use new gaskets (3) when changing or
checking the valves.
ATTENTION! Before tightening the 4 bolts for the diaphragm cover (B) the diaphragm must be positioned between
centre and top to ensure correct sealing between diaphragm pumphousing and diaphragm cover. Turn crank
shaft if necessary.
The maintenance and renewal intervals for the following will depend very much on the conditions under which the
sprayer will be operated and are therefore impossible to specify.

changed. If fluids have reached the crankcase, re-grease the pump
thoroughly. Also check that the drain hole at the bottom of the
pump is not blocked. Reassemble with the following torque setting.
