Safety concerning maintenance work on the cutting unit
When working on the cutting unit the tractor must be stopped and
secured.
This prevents the machine from suddenly starting to rotate.
If the tractor and the PTO shaft have not been connected in
accordance with the instructions, serious accidents causing damage
to limbs can occur.
When working on the transmission:
• The tractor engine must be stopped.
• The ignition key must be removed.
• The tractor's PTO must be disconnected.
• The tractor hydraulic system must be disconnected.
• The hand brake must be activated.
