If the hand throttle has been pivoted to the stop position of the second notch (preferred speed), the engine speed must be set to
approx. 2450 rpm. A quick-release coupling with a short hose must be connected to one of the quick-release couplings for the "pivot
attachment device" function (Pos. 148 and 150).
A coding plug must be connected for enabling "side brushes spreading mode". When the above speed is set, the potentiometer is fully
open and "pivot attachment device" is actuated, the feed quantity from this line should be between 6 and 8 litres per minute.
In the case of an adaptation, the maximum quantity for the proportional valve must be set to the maximum quantity using the
trimming
potentiometer
provided on the control unit.
Note: If the A1 electronics are replaced, the minimum quantity must also be set to 5 ± 0.25 litre using the relevant trimming
potentiometer, measured on the flow for the side brushes/spreading mode (Pos.149).
