of the table. When the bale is on the table, the clearance C on both
sides between the bale and both support rollers should be maximum
150 mm.
The support rollers can be placed in three positions. The middle or the
right hole are recommended.

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:
• the table must be fully tipped forwards
• the loading arm lock must be applied
• the right wheel must be in transport position
The loading arm must be locked into transport position.
> Move up the loading arm completely
> Mount the pin
> Lock the pin with the locking pin
The locking pin must be in the left hole.

Check the machine before road transport by means of the checklist:
• The tractor hydraulic is switched off?
• All valves are closed?
• Crop residues and heavy dirt are removed?
• Cables and lines are placed in that way they will not tension or get
in touch with the tractor rear tyres during curve driving?
Road transport
• 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 the 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 speed of 25 km/h. Obey the national
and local speed limits.
• Pay attention to sufficient driving and braking capacity. Then driv-
ing and braking capacity are influenced by the attached machine
(longer braking paths because of larger driving power).

Maintenance
Wheels/tyres
Do not drive with worn-out or damaged tyres
Exchange worn-out or damaged tyres immediately. Especially during
road transport with such tyres an increased risk of accidents exists.
Correct repairwork only
Repairwork on wheels and tyres must only be carried out
• by professionals
• with the correct fitting equipment
Mounting wheels and tyres requires sufficient knowledge and availability of prescribed tools and equipment being in perfect condition.
Serious personal injuries or machine damages can occur.
Tyre dimensions as prescribed
Do not fit other tyre dimensions than prescribed. Fitting other tyre dimensions can cause accidents. Personal injuries or machine damages can occur.
Prescribed tyre pressure only
Only use the prescribed tyre pressure. Using the wrong tyres pressure
can cause serious personal injuries, machine damages or traffic accidents.
When working on the wheels and tyres make sure that the machine
• has been placed on the ground safely (use support jack)
• is secured by chocks against unintentional rolling
Tyre pressure
Check the tyre pressure regularly
• once a day
• before every road transport
• before and after every season
Tyre size Tyre pressure (bar)
11.0/65-12 2.3

Hydraulics
Hydraulic hoses
Filter hydraulic block
Indicator
Take care at welding work
Do not carry out welding work near to hydraulic hoses. Hydraulic oil
can ignite very easily.
Hydraulic device pressureless
Before replacing the hydraulic hoses, the hydraulic device must be
pressureless. When working at a hydraulic device which is under pressure, by unintentional movements at the machine or by squirting hydraulic oil, accidents can occur.
Hydraulic hoses age without recognizable external indications, too.
Therefore, we recommend to replace the hydraulic hoses every six
years.
> Make the hydraulic device pressureless
> Switch off the engine and remove the ignition key
> Discouple the hydraulic hoses
> Replace the hydraulic hoses
Stay clear of the table area
Stay clear of the table area while it is rotating. Serious injuries can occur.
Filter
The filter is situated near the hydraulic block of machines with control
box only.
The filter contains an indicator on top of it. The indicator shows, whether the filter has to be exchanged or not.
Indicator colour Meaning
green The filter is clean
red The filter must be replaced
Only check the indicator when the hydraulic oil is at working temperature.
When the machine is hitched onto a tractor with a closed centre hydraulic system, the tractor engine must be at the rpm as during wrapping before checking the filter indicator.
> Check the indicator every 3000 bales or once a season
> Replace the filter every 8000 bales and once a season

The table roller drive chain is under the cover, at the side of the table.
The chain should have a slight slack.
> Check the chain tension every week
Correct the chain tension as follows:
> Loosen the lock nut
> Move the chain tensioner to the left or to the right until the chain is
tensioned correctly
> Tighten the lock nut
The table lock prevents the table from turning in the wrong direction.
When the table is fully down, the length of the bolt must be adjusted
so that the table lock
• is open when the table rotates to the left
• is closed when the table rotates to the right
Bolt
The table lock must be adjusted if it does not work correctly.
> Turn the bolt to the left or to the right until it touches the frame
