Maintenance
9.3.8 Tyres
• Repairs to the tyres should be carried out by trained personnel only using the right tools.
• Park the round baler on firm, level ground. Place wheel chocks under the tyres to prevent
unintended rolling.
• Regularly check that wheel nuts are properly seated and tighten if necessary!
• Do not stand in front of the tyre when inflating it with compressed air. The tyre could burst
if too much pressure builds up inside. Risk of injury!
• Check the tyre pressure at regular intervals.
Always slacken and tighten the wheel nuts in the
sequence shown in the diagram at right.
Check the wheel nuts 10 operating hours after mounting
and tighten if necessary.
After this, check that the wheel nuts are properly seated
every 50 operating hours.

Check the tyre pressures regularly and top up if necessary.
The tyre pressure is dependent on the tyre size.
The values are shown in the table.
9.3.9 Tyre air pressure
*) The recommendation applies especially to the typical mixture of operation (field/road). If necessary, the tyre air
pressure can be reduced to the minimum air pressure for exclusive field operation.
In that case, however, the change in the dynamic behaviour of the tyre must be noted, especially for road travel.
