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.
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.
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.
