Checking and adjustment of the cutting unit’s ground pressure
To achieve the best cutting results the cutting unit should follow the underlying surface without pres- sing too hard against it.
The pressure is adjusted with a screw on each side of the machine.
Adjusting of the cutting unit’s ground pressure is conducted as follows:
1.Place a set of bathroom scales under the cutting unit’s frame (front edge) so that it rests on the scales. If necessary a block can be placed between the frame and scales so that the sup- port wheels do not bear any weight.
2.Adjust the unit’s ground pressure by screwing in or out the adjusting screws located behind the front wheels on both sides.
The ground pressure should be between 12 and 15 kg and the springs evenly tensioned.
