Knife guide:
When free-play between the guide plates (C) and the knife holders has reached 1.5 mm or a new knife has been fitted and every time after the
fasteners have been loosened, a basic readjustment is required.
Important for the readjustment of the knife guides is to first correctly adjust a single guide and then work on the following ones. After the
adjustment of each individual guide the knife must move freely. Adjustments are carried out as follows:
1. Loosen the clamp bolt (1) of the knife holder.
2. Unscrew the mounting screws (5) and (4)
3. Remove and clean the knife holder with angles (G) as well as friction plates (E) then re-assemble it.
4. Slightly tighten the mounting screws (5, 4) and then the clamp screws (1) with thumb and forefinger.
5. Set a protrusion of 2 mm between the movable and the stationary knife and secure it with 2 clamps or vice grips.
Attention: It is important to ensure that "knife protrusion" is equal over the whole length of the cutterbar -
6. Bring the friction plates (E) in contact with the guide plates (C).
7. Move the angle (G) and the knife holder until a free-play between the guide plate (C) and the knife holder of 0.2 mm (post card
thickness) remains.
8. Tighten the mounting screws (4), (5), repeat this procedure for the remaining guides in the same sequence.
9. Press don on the knife holder and, at the same time, tighten the clamp bolt (1) (Md = 50 Nm).
Attention! After the adjustment the knife must move freely back and forth in the guides-
Adjusting the cutting height
The cutting height of the cutterbar is set through the skid mount (b) and the gliding skids
(c) attached to the cutterbar. An adjustment to the cutting height is carried out as
follows:
Skid mount (b) attached as skid. The cutterbar cuts close to the ground.
Skid mount (b) attached for mounting of gliding skid(c). The cutterbar cuts close to the
ground.
Gliding skid(c) attached. For adjustment, loosen the clamp bolt (a) and turn the gliding
skid (c) into the desired cutting height position.
Cutterbar:
After every cutting operation, the top knife has to be removed to assure proper cleaning of the cutterbar and all the relevant guiding and
friction surfaces. Before the reassembly of the knife, check and repair damaged parts, straighten bent knisections, sharpen blunt sections and
apply lubrication to all relevant guide and frictions surfaces. If no cutting work is to be done for an extended period, remove knife and m
