Safety valve
For safety, the attachment is equipped with a valve that prevents using the attachment when it has been lifted
off the ground. The valve stops the hydraulic flow to the hydraulic motor of the attachment when the
attachment is raised or when the floating has been set too low. On uneven ground the safety valve may act
too frequently, therefore setting the correct floating position is important for the correct operation of the
attachment.
When the linkage is set to the position
indicated in the figure, the motor will not turn
because the safety valve is activated. The
quick coupling plate of the loader boom must
be tilted forward sufficiently.
The floating position must be checked if the
motor does not rotate at all or only rotates
inconsistently even when the auxiliary
hydraulic control lever of the loader is locked
on.
Check the operation of the safety valve regularly. Tilt the quick coupling plate up (bucket fill direction) to
activate the valve; the motor must stop once the linkage is fully tilted. Never operate the attachment if the
valve is faulty, contact service if needed.

Adjusting the cutting height
The cutting height can be adjusted by using the plastic sleeves on the vertical axles of the bearing wheels.
The mower does not need to be disconnected from the loader while adjusting the height. To adjust the height:
1.
Lift the attachment slightly off the ground with the loader and shut
down the engine.
2.
Remove the cotter pin from the vertical axle of the bearing wheel.
Pull the wheel off its holder.
3.
Move some plastic sleeves from above the bracket to below it or
vice versa, depending on whether you wish to raise or lower the
mower.
4.
Push the axle back in through the bracket and reinstall the cotter
pin.
5.
Repeat steps 2–4 for each wheel. Ensure that all wheels are
adjusted to the same height.
There are two thicknesses of plastic sleeves (10 &
20 mm) for more accurate adjustment of the
operating height. Adjust all wheels to the same
height.
