Safety
Before road
transport
Before road transport will take place, please read the following safety
instructions. The compliance is prescribed and helps you to avoid
accidents.
Close valves
Before road transport close all valves. With open valves and false
operation the lifting cylinder can be lowered. Traffic accidents can be
caused.
Clean the machine before road transport
Clean the machine, before every road transport, from crop residues
and heavy dirt. Crop or dirt, falling at the road, can cause a slippery
state of the road. This can lead to fatal accidents.
Road transport must be done in transport position. To bring the
machine into transport position, the following steps are necessary:
> Switch off the pto
> Wait until all moving parts really stand still
> Remove crop residues and heavy dirt
> The lateral guard must be folded up and locked
> The machine must be placed into transport position

Placing into
transport position
Lateral guard
Guarantee correct hydraulic couplings
Before preparing the machine, strictly check if the hydraulic couplings
are coupled correctly to a single acting hydraulic valve. Not correct
coupled hydraulic couplings can cause unpredictable movements of
the machine.
Sufficient distance to cables and wires
When transporting the machine in folded-up position, take care about
sufficient and safe distance to high-voltage cables and overhead
wires. Too less distance can cause touching or entanglement of
cables and wires. Serious personal or machines damages can occur.
Before the machine is travelling by road, the machine must be folded
up completely.
> Fold up and lock the lateral guard
> Use the single acting hydraulic valve, coupled to the blue marked
hose, to lift the machine in headland position
> Use the double acting hydraulic valve, coupled to the red marked
hoses, to lift the machine in transport position
> Use the 3-point hitch to lift of lower the machine to the desired
transport height

Checking the
machine
Road transport
Check the machine before road transport by means of the checklist:
• Machine is fully folded?
• Tractor hydraulic is switched off?
• Crop residues and heavy dirt are removed?
• Cables and hoses are placed in that way they will not tension or get
in touch with the tractor rear tyres during curve driving?
• Before starting driving, check the close environment. Always take
care of a clear view and especially at children in the working
environment of the machine.
• Lock hydraulic valves of the tractor before road transport
• Do not transport any persons or objects at the machine
• Adapt the drive speed to the road conditions
• Do not exceed the maximum drive speed. Obey the national and
local speed limits.
• Pay attention to sufficient driving and braking capacity. Then
driving and braking capacity are influenced by the attached
machine (longer braking paths because of larger propulsion).
