Dry forage extension
- Lever (W) in position "DA".
- Lever on control panel in position "B".
- Engage servo-control (ST) on tractor.
Folding extension up or back gradually.
Swivelling cutter unit
Caution!
Do not reach into swivel range of cutter bar
when swivelling in / out.
- Lever (W) in position "SW".
- Lever on control panel in position "B".
- Engage servo-control (ST) on tractor.
Both cutter bars swivel in resp. out.
• When only one cutter bar
is needed for mowing, the
lower cutter bar can be
swivelled out using the
accoompanying lever (H).
Obstructions when swivelling
- Remove foreign body from swivel range.
• If the cutter bars do not swivel in properly, then a pressure
loss in the cutter unit hydraulic could be the cause.
Remedy by hydraulically filling the reservoir
- Move lever to position "E" on 3-way valve.
- Actuate servo-valve. The cutter bar is swivelled out
hydraulically.
- Leave servo-valve (ST) in the press position for a few
seconds while moving the lever on the 3-way valve to
position "0".
• If obstruction cannot be removed then check gas fill pressure
(100 bar nitrogen) in hydroreservoir.
Alteration of gas container pressure
• This work may only be carried out by customer service or a
specialist.
• In order to reduce or increase the pressure in
the gas container a special filling and checking
device is necessary.
Note
• According to manufacturer's information all
gas containers have a slight pressure drop
after a certain amount of time.
• The gas loss (nitrogen) amounts to 2-3 % per year.
• After 4-5 years it is recommended that container pressure be
checked and if necessary corrected.
Maintenance
Beware!
No welding, soldering or mechanical works of
any kind may be carried out on the container.
• Hydraulic oil change according to tractor manual.
• Before welding on trailer disconnect all plugs from tractor
and disconnect trailer.
