6 - Maintenance
6.7
The maintenance and replacement intervals for the following will depend very much on the conditions under which the
sprayer will be operated and are therefore impossible to specify.
Model 321 pumps:
Valves
Remove valve compartment (1). Before changing the valves (2) -
note their orientation so they are replaced correctly. It is recom-
mended to use new gaskets (3) when changing or checking valves.
Diaphragms
Remove the diaphragm cover (4) after having dismantled the valve
compartment as indicated above. The diaphragm (5) may then be
changed. If fluids have reached the crankcase, re-grease the pump
thoroughly.

General info
Occasional maintenance
The MANIFOLD valve can be adjusted if it is too tight to operate - or
if it is too loose (=liquid leakage). Correct setting is when the valve
can be operated smoothly by one hand. Use a suitable tool and
adjust the toothed ring inside the valve as shown on the drawing.
