Safety concerning maintenance work on the cutterbar
When working on the cutterbar, 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 according to
the instructions serious accidents resulting in torn off 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 should be disconnected.
• The hand brake should be activated.
