Safety concerning maintenance work on the cutterbar
When working on the cutterbar, the tractor must be stopped and

accordance with the instructions serious accidents causing damage to
limbs can occur.
When working on the cutterbar:
• The tractor engine must be stopped.
• The ignition key must be removed.
• The PTO shaft must be disconnected.
• The tractor hydraulic system must be disconnected.
• The hand brake must be activated.
