10. Correction of stroke length setting
To avoid excessive metering, the metering line must
be returned to the chemical tank during setting (if
necessary).
1. Operate pump with automatic control (if
necessary, by pressing the start key for FL).
2. Regardless of the indicator position, loosen the
fastening screw and turn the stroke length
adjustment knob counterclockwise until the pump
no longer delivers or, in the case of no-pressure
delivery, the flow rate has reached the minimum.
If zero delivery could not be attained because
the knob reached the stop position, remove the
knob after loosening the fastening screw, turn it
to the right and reattach it. Then turn again to the
left until the pump no longer delivers.
