Mechanical release device
spraying pump and fan
In the event of an electrical defect, there is a
hydraulic valve block at the right on the hydraulic
pump for mechanically releasing the spraying
pump or the fan. With this valve the spraying
pump or the fan can be selected as long as the
hydraulic pressure supply is intact.

Screw in the small screw on the top of the
release device (1) to the right until the spray-
ing pressure in the spraying boom has the
desired value.

In this way any remaining chemical can, if
necessary, be placed before a repair is car-
ried out.

After repair work has been carried out, un-
screw the screw of the release device to the

Fan
In the event of an electrical defect of the valve
on the hydraulic venting device, cooling of the
engine, the hydraulics, the charge air and the
A/C system will no longer work and the machine
is therefore no longer cooled.
¾
Using the release device (2) a speed can be
specified on the fan to cool the cooler pack -
age again.
¾
Turn in the screw of the release device (2)
toward the right. This increases the fan speed
and the machine cooling works again.
¾
After repair work has been carried out, un-
screw the screw (2) of the release device to
the left.
Mechanical release device
of access ladder
In the event of an electrical defect, a valve for
mechanical release is located on the hydraulic
valve block for the access ladder. The hydraulic
valve block is located next to the cabin. With this
valve the ladder can be raised and lowered as
long as the hydraulic pressure supply is intact.
