Bypass valves

Hydraulic pressure must be released in order for the ride-on mower to be moved when the engine is shutoff.

The hydraulic pressure is opened and closed with a bypass valve.

If you try to drive the machine without hydraulic pressure, it will not move. The drive on the axle is disengaged if one valve is open.

The P 520D and theP 525D has two valves, one valve for the front axle and one for the rear axle.

IMPORTANT! Always drive the machine with both valves closed.

•Bypass valve rear axle

-The hydraulic pressure is released by opening the locking nut (1) 1/4-1/2 turn anti-clockwise, then the bypass valve (2) 2 turns.

-The hydraulic pressure is switched on by closing the valve. Close the valve nut (2) fully before tightening the locking nut

(1).

•Bypass valve front axle

-The hydraulic pressure is released by opening the locking nut (1) 1/4-1/2 turn anti-clockwise, then the bypass valve (2) 2 turns.

-The hydraulic pressure is switched on by closing the valve. Close the valve nut (2) fully before tightening the locking nut
