with cutting unit, without swivel floor
The cutting device is directly actuated with the double-acting
tractor control valve. (The actuating direction can be changed by
swapping the connected hydraulic hoses.)
In order to ensure free movement of the individual blades, it is
recommended to move the cutting device in and out several
times each day.
Note: The cutting device is safeguarded from being overloaded
by a single hydraulic pressure valve serving the cutter blades.
This responds at a factory set pressure limit. This is also the
pressure available for moving in the blades. Depending on the
situation, the hydraulic pressure may not necessarily suffice if
the blade grooves are blocked.
Remedy:
1. Move the ball valve under the left protective guard towards
the back (fig. 55).
1724-30
2. Activate the control valve until the blades are in the cutting
position.
3. Move the ball valve once again towards the middle of the
baler.
4. Move the blades once more in and out. Only after this
process can the baler be brought into normal operation.
Warning: If the ball valve lever (fig. 55) is pointing towards the
back, the common protection of the cutter blades is deactivated!
After the blades have been moved upwards, the lever must
once again be brought back towards the middle of the baler!
(fig. 56)
After setting back the ball valve, it is absolutely necessary that
the blades are once again moved in and out. Otherwise, the
machine overload will result in a cancellation of the warranty!
