5.

If the cutting unit does not lower completely, or if 
the blades do not rotate, lower the cutting unit 
completely using the hydraulic lifting lever.

In order to ensure that the hydraulic cylinder is in 
the outer position, hold the lever in the forward 
position for a half to one second.

The differential lock can be used during operation 
via the pedal on the left side.

In order not to get stuck, one can engage it shortly 
before the obstacle.

1.

Engage the differential lock when necessary by 
pressing the pedal. If a wheel spins, let the drive 
pedal up a little.

2.

Ensure that the differential lock is disengaged 
when the pedal is released. Use small steering 
movements or reverse a little until the pedal 
returns to its normal position.

If the engine has been worked hard, it is preferable to 
let the engine idle for a minute so it runs at its normal 
working temperature when stopped. Avoid idling the 
engine for long periods, as there is a risk of carbon 
build-up on the spark plugs.

1.

Lift the cutting unit with the hydraulic lifting lever.

The unit can then be secured in the raised position 
if necessary by moving the mechanical lifting lever 
backwards to the lock position.

If the cutting unit is left in the lower position, 
the start lock circuit will prevent you starting 
the engine.
