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.

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.

Replacing the break-pin (BioClip 103)

The blades are fitted with a break-pin to protect the BioClip unit and its drive when colliding with obstacles. A domed, spring friction washer is fitted to each blade bolt. The washer must always be replaced with a new washer when replacing the break-pin. Otherwise the break-pin can break causing the blades to collide.

Only use original spare parts. A set containing a blade, break-pin and friction washer can be purchased from your dealer.

1.Put the unit in the service position, see ”Placing in the service position”.

2.Remove the blade (2A) by removing the blade bolt with washer and friction washer (2B).

3.Remove the remains of the broken break-pin

(3).

4.Make sure the contact surfaces (4) on the blade and the blade mounting are free from metal. Clean if necessary.

5.Fit one new break-pin (5) in the blade mounting.

6.Fit the blade (6), make sure it is fitted as illustrated.

7.Fit a new friction washer (7) with the concave face turned towards the blade.

8.Fit the blade bolt with washer (8). Tightening torque 45-50 Nm (4,5-5 kpm)
