Grind the Cutting Unit Knives
WARNING:
Chopper knives can cut fingers and hands.
WARNING:
Wear gloves and use suitable tool when
handling chopper knives.
WARNING:
Do not do work on the magnets of the blade holders if you have a cardiac pacemaker or other implant that
can be impaired by magnetic fields.
CAUTION:
Do not hit the knives with any kind of tool from the bottom. This may damage the magnets and splinters may
brake loose and cause injury.
CAUTION:
Wear protective gloves when you do work on the cutting unit blades.
NOTICE
Sharp blades save driving power, provide for a good cut quality and optimum crop throughput. How often the knives
must be regrinded depends on the type of crop and the amount of contamination.
Remove the Knives
1. Insert the cutting device to cutting position with the controller and double acting valve in the tractor.
2. Swivel the feed channel floor halfway down with the controller and double acting valve in the tractor.
Do not swivel completely down because the knives must still project from the feed channel floor.
3. Open the tail gate with the single acting valve in the tractor.
4. Make sure the PTO shaft is switched off, stop the tractor engine and remove the key.
5. Secure the tailgate with the hydraulic shutoff valve (1) (see Figure 4 on page 2-16) .
