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 following 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 should be disconnected.
• The hand brake should be activated.
Check the machine's knives regularly
The machine's knives must be regularly inspected.
Worn or damaged knives can unbalance the rotating parts.
Vibrations can cause damage on the machine.
After 1 hour of use
Thereafter, every day
The knives are checked in the following way:
> Open the guards around the machine's cutterbar.
> Turn the cutting discs by hand until the damaged knife is in the
position shown.
> Inspect the condition of the knives for wear.
> Inspect the bolt for damage or wear.
• If the bolts are damaged or worn, they must be changed.
NB
The minimum diameter of the bolt must not be less than 16 mm.

> Check that the bolt is fully tightened.
> If not, use a suitable tool and tighten the bolt to a torque of 95 Nm.
NB
If the machine is fitted with knife quick release*, the same requirement
applies for bolt wear.
