The valves are fitted on the RH side of the tractor so thatthe control levers go straight into the cab.Both of these valves are adjustable for either single---acting ordouble---acting function. One of these valves can be lockedmechanically in different positions and the other valve has a”floating position”.Standard quick ---action couplings or Push ---Pull type coup-lings are available. A leakage oil reservoir is standard.As an extra equipment can be fitted;a) two extra valves+brake valve for trailerorb) one extra valve equipped with an oil flow controlvalve+brake valve for trailer.For later tractors two extra valves+brake valve for trailer+oilflow control valve can be fitted.When repairing or changing the valves, they are accessiblethrough the hole in the cab RH side mudguard.1. Adjustment between single/double---action2. Adjustment between single/double---action3. Position lockingIntermediate plate A and the pump side end plate B havebeen attached to the valve bracket (3 pcs bolts). Tighteningtorque for the bolts is 45 Nm.Bolts C (4 pcs) through the valve block set must be tightenedevenly and crosswise to 23 Nm. Otherwise the valve spoolscan get trapped. When fitting extra valves, bolts C should bechanged for longer ones.Note! When fitting valve blocks, ensure that the o---rings be-tween the blocks are correctly positioned in their grooves.312 6181--- 64ABC
