Connecting
The machine must be properly connected to a
tractor before any machine movements.
DANGER
Serious accidents caused by the machine roll-
ing away!
¾
Do not move the machine without a brake
line connected.
¾
When connecting machines with pneumatic
brake always connect the yellow connection
(brake line) first.
NOTE
¾
Route cables, lines and hoses so that they
will not be damaged during operation (when
cornering).
¾
Check all plug-and-socket connections (hy-
draulic, electric and pneumatic) for cleanli-
ness and firm seating.
Dirty connectors will contaminate the flowing
media. The connectors therefore become
worn and this results in malfunctions and
failures in the connected assembly groups.
1. Clean the towing facilities of machine and
tractor and check for wear.
2. Back up the tractor to the crop protection
sprayer and secure against unintentional
starting and rolling away.
3. Coupling the machine.
Machines with drawbar eye:
•
Adjust the height of the drawbar by crank-
ing the support so that the machine can
be picked up.
•
Engage the machine.
•
Insert the bolts and secure them.
Machines with ball and socket coupling:
•
Lower the drawbar or spherical cap onto the
ball by cranking on the support.
•
Position the hold-down.
•
Check the gap between hold-down and
spherical cap and adjust; see chapter
Maintenance overview .
4. Connect hydraulic hoses, brake system lines
and cables for lighting.
5. Connect the sprayer controls to the ISOBUS
socket on the tractor.
6. Couple the propshaft to the PTO-shaft of the
tractor. To do so, slide the propshaft over
the PTO-shaft until it engages. Secure the
propshaft guard against rotating along.
7. Lift the support foot to transport position. Pay
attention to the chapter Support .
8. Remove the wheel chocks and insert them
into the brackets provided and secure them.
9. Release the parking brake.
10. Check before starting to drive whether the
machine has been properly connected and
secured.
Connecting the hydraulics
¾
Connect the hydraulics only when the system
has been de-pressurized on both tractor and
machine sides. The hydraulic system is under
high pressure.
¾
Escaping fluid can penetrate the skin and
cause serious injuries. In the event of injury,
consult a doctor immediately.
To rule out wrong connections, the
plug-in couplings are marked.
¾
With all hydraulic movements, slow down the
control unit before the machine components
reach the stop position.
