3.7.3 Film cutter settings
The opening and closing speed of the film cutters must be set correctly. If their speed is too high, the wrap-
ping film might be damaged instead of neatly cut when the wrapping arms stop. The film cutters speed, left
(valve P4) and right (valve P5), may be reduced by turning the valve clockwise. Both cutters should be
equally set. The cutters should move softly.
Default setting: Close the valve and then open 1/2 turn.

Film cutter valves
Setting the speed: Turning the valve clockwise decreases the speed. Turning the valve counterclockwise
increases the speed. Adjusting the height of the cutters is normally not necessary. The film should lay on the
middle of the cutter when cut.
Film cutter rollers: Film cutter, upper position: Both rollers must roll freely. Film cutter, lower position: The
outer roller should be kept locked. This is in order to hold the film so that it is cut, not ripped. Make sure that
the knife is centred between the two rollers. Straighten the knife, if necessary. See Figure 3.7

3.7.4 Wrapping table tilt speed
Adjusting the wrapping table tilt speed may affect the speed of the bale when rolling off the wrapping table
during bale drop. Adjusting the wrapping table tilt speed is done by turning valve P3. Clockwise decreases
the speed. Counterclockwise increases the speed. Default setting: Close the valve and then open 3/4 turn.
