Alternative
Fill the pressure accumulator (1) to ap-
prox. 10 bar.
Operate the pump at the specified
speed.
Observe the pressure hoses of the pump.
If the pressure hoses vibrate, or the
pressure of the pressure measuring sys-
tem varies significantly, relieve thepres-
sure using a filling device with a tyre in-
flation valve.
If the pressure hoses of the pump vibra-
te only slightly or the pressure no longer
oscillates, this means the correct pres-
sure is set on the pressure accumulator.
Install the cap (2).
