ATTENTION!

Do NOT operate mower while reversing.

4.5.9 HYDRAULIC SAFETY DEVICE

The mower is equipped with a hydraulic safety device, which protects the machine against

damage resulting from collision with obstacles. When colliding with an obstacle the lifting arm

rises and swings backwards. After passing the obstacle the cutting unit returns to the

horizontal position and swings forward using the lifting arm inclination hydraulic cylinder. In

order to enable action of the hydraulic safety device, both cylinder valves should be set in

open position.

4.6

DISCONNECTING FROM TRACTOR

DANGER

Reduce pressure prior to disconnecting the hydraulic system.

Before disconnecting mower from the tractor's linkage, lock the lifting arm in parking
position using pin (3) and cotter pin (4) (figure 4.15). Do not disconnect mower from
tractor before lifting arm is interlocked.
