BAG0175.3 07.18
• Check the compatibility of the hydraulic fluids before connecting
the machine to the hydraulic system of the tractor.
Do not mix any mineral oils with biological oils.
• Observe the maximum approved hydraulic fluid pressure of 200
bar.
• Only couple clean hydraulic connectors.
• Plug the hydraulic plug(s) into the hydraulic sock
feel the hydraulic plug(s) locking.
• Check the coupling points of the hydraulic hose lines for a cor-
rect, tight seat.
1. Place the tractor control unit in float position (neutral).
2. Clean the hydraulic plugs of the hydraulic hose lines before cou-
pling up.
3. Couple the hydraulic hose line(s) with the tractor control unit(s).
5.2.2 Uncoupling the hydraulic hose lines
1. Place the tractor control unit in float position (neutral).
2. Release the hydraulic plugs from the hydraulic sockets.
3. Fasten the hydraulic plugs in the empty coupling points.
5.3 On-board hydraulic system (optional)
The on-board hydraulic system is driven by the
hydraulic slide-on pump and is responsible for
driving the fan.
Connect the hydraulic slide-on pump (1):
1. Clean and grease the universal joint shaft
stub of the tractor.
2. Insert the hydraulic slide-on pump on the
universal joint shaft stub and, depending on
the design, either secure with pins or screw
down.
3. Secure the hydraulic slide-on pump against
movement by attaching the chain (2).
4. Check the course of the hydraulic lines.
Ensure that the hydraulic lines are long
enough in all operating positions, do not
chafe against other parts and do not be-
come caught or kinked in any area.

WARNING
Observe maximum permissible universal joint shaft speed of
1000 rpm.
