MAINTENANCE

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.

1. Check the air pressure in the tyres 60 kPa (0.6 kp/cm2).

2. Place the Rider on a flat surface.

3. Put the lifting lever in the mowing position.

4. 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 support wheels do not bear any weight.

5.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.

Checking the cutting unit’s parallelism

Check the parallelism of the cutting unit as follows:

1.Check the air pressure in the tyres 60 kPa (0.6 kp/cm2).

2.Place the machine on a level surface.

3.Put the lifting lever in the mowing position.

4.Measure the distance between the ground and the front and rear edges of the cutting unit hood. The cutting unit should slope forwards slightly so that the rear edge is 2-4 mm higher than the front edge.
