4. Useful hint: Mark the positions of the blades on
the respective pulley using a felt-tip pen.
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.
Belt change on cutting unit with rear ejection,
side ejection and Combi 112
On these cutting units with "collision-proof" blades,
the blades are driven by one V-belt. Do as follows
to change the V-belt:
1. Remove the cutting unit.
2. Undo the bolt on the lift strut and the two screws
on the cover. Lift the cover off the cutting unit.
3. Loosen the spring (4) that tensions the V-belt
and pry off the belt.
Simply reverse the procedure to fit the new belt.
