WORK POSITION AND ADJUSTMENTS
BEFORE CARRYING OUT ANY OPERATION SUCH AS MAINTENANCE OR ADJUST-
MENT ON THE MACHINE, STOP THE TRACTOR ENGINE, REMOVE IGNITION KEY AND
WAIT FOR ROTATING PARTS TO STOP.
MAKE SURE THERE IS NOBODY IN THE MACHINE OPERATING AREA BEFORE LOWERING
THE ROTORS INTO THEIR WORK POSITION.
To switch the GA 8001 H from the transport position to the work position, proceed as follows :
- Pressurize the hydraulic cylinders so that they close up against their stops.
- Pull cords (1) (photo 17) to unlock rotor arms.
- Shift the tractor valve to lower the rotors. Release cord (1) once rotors start being lowered.
- Once the rotors are completely lowered, the machine is in the working position (photo 19).
- Remove tine arms from their racks and fit them on the rotors (see page 24).
- Unlock foldable guards (4) using handles (3) and fold them outwards into the work position (see arrows, photo
18).
- Store handles (3) in the spring clips (2) (photo 18).
Maintain the tractor hydraulic valve in the free floating position during work.
Wheel undercarriage height adjustment (photo 20) :
- Using the tractor hydraulics, slightly lift the rotors to clear the wheels off the ground,
- adjust the desired height of the undercarriage by rotating the crank (5),
- activate the tractor hydraulics to lower the rotors on the ground.
Note : The oblong holes (6) are used as marks enabling to check that both undercarriages are adjusted at the
same height.
