MAINTENANCE

Replacing the cutting unit belt

1.Remove the cutting unit.

2.Remove the front bolt from the parallel strut and tip the strut backwards. Push the height adjustment strut forwards.

3.Loosen the two bolts holding the protective hood and then lift off the hood.

Useful hint: Mark the positions of the blades on the respective pulley using a felt-tip pen.

WARNING!

Wear gloves to protect your hands when working with the blades.

4.Loosen the three bolts 1/2 - 1 turn. Press the sides of the belt together to give maximum slack and tighten one of the bolts. Replace the belt and tighten as shown (see decal on cover). Set the blades at 90º to each other and loosen the bolt again. The spring ensures the correct belt tension. Check the positions of the blades again and adjust if necessary by repositioning the belt on the teeth. Tighten the three bolts to 45 Nm/32 lbft.

IMPORTANT INFORMATION

The blades on a Combi 103 unit should be set at 90 degrees to each other. In all other cases the blades can collide and cause serious damage to the cutting unit.

5.Fit the protective cover over the belts and replace the parallelism arm.
