Repair Instructions
3. Remove the bolts holding the protective cover
and lift off the cover.
Tip: Mark the position of the blades on respec-
tive belts with a felt-tip pen.
WARNING!
Protect your hands with gloves
when working with the blades.
4. Loosen the three screws 1/2 - 1 turn. Squeeze
the belts to their maximum slackness and
tighten one of the screws. Change the belt and
tighten as shown in the illustration (decal is on
the cover). Set the blades at 90° angles and
loosen the screws again. The spring provides
the proper tension to the belt. Check the posi-
tion of the blades again, adjust as needed by
re-setting the belt. Tighten the three bolts to
45 Nm.
Replacing the Cutting Unit’s Belts
Belt Replacement on FRM 2115 A
The 103 mulching unit has a toothed drive belt. The
drive belt powers and synchronises the rotation of
the blades. The belt is located under the cover on
top of the cutting unit.
1. Dismantle the cutting unit.
2. Loosen the front bolt on the parallel strut and
swing back the strut. Swing the height adjust-
ment strut forwards.
5. Fit the protective cover over the belts and
secure the parallel strut.
IMPORTANT INFORMATION
The blades on the mulching unit should
be positioned at 90° angles to each other.
Otherwise the blades can go against each
other and damage the cutting unit.
