7. Attach or release the quick-action couplings.
DANGER: When connecting auxiliary cylinders and hydraulic
motors, ensure that the hoses are attached to the correct
couplings. If you attache the hoses incorrectly, the functions are
reversed.
IMPORTANT: Use only couplings that comply to the standards.
IMPORTANT: Clean the quick-action couplings thoroughly before attaching
any auxiliary hydraulic equipment. The caps on the couplings must be fitted
when the auxiliary equipment is not attached.
NOTE: When attaching implements to the auxiliary hydraulics, connect the
return coupling of the implement to the return coupling of the tractor.
NOTE: Make sure that the quick coupling does not leak after disconnecting
the hose.
8. Start the engine.
WARNING: Do not transport anything on the auxiliary hydraulic
valves while driving on the road. The load, trailer link steering and
such have to be locked (for example mechanically).
3.14.4
Connecting an external hydraulic motor to the auxiliary hydraulics
You can attach a hydraulic motor to the tractor auxiliary hydraulics. The motor
can be rotated in one or both directions.
•
To rotate the hydraulic motor in only one direction:
•
Attach the return coupling to the tractor return coupling without the shock
valve.
•
To rotate the hydraulic motor in both directions (if you are attaching the
couplings to both +/- ports):
•
Mount the separate shock valves to the hydraulic motor if they are not
already standards in the hydraulic motor.
NOTE: Pay attention to the hydraulics oil temperature, because high
temperatures are bad for the lubrication and can damage the hydraulic pump or
the hydraulic motor. The recommended working temperature is below 80°C and
the maximum limit is 93°C. Stop the engine if the maximum temperature is
reached. You can follow the hydraulics oil temperature on the tractor terminal
display.

Using the front linkage
You can control the front linkage by the control lever for auxiliary hydraulics rear
valve 3.
