22. Diagnostics of hydraulic system defects
Loose the lock nut (2) and using the screwdriver turn the adjust-
ing screws (1) (unscrewing means higher frequency and oppo-
site).
The upper screw “A“ adjusts frequency of the high amplitude.
The lower screw „B“ adjusts frequency of the low amplitude.
Do not adjust higher frequency than that specied by manufac-
turer. Do not switch the frequencies - the lower frequency must
comply with the higher amplitude and opposite. Manufacturer
adjusts the lower frequency and the higher amplitude at the
same direction as if the roller travels forward.
Adjust with the engine o!!!
! NOTE !
The zero position of the hydraulic generator power
cylinder has been adjusted by the manufacturer on
the upper screw (1). Any handling of this screw is
not permitted.
The frequency meter may be ordered from the anu-
facturer or your dealer.
