Changing the belt on the Combi unit
On these cutting units with "collision-proof" blades,
the blades are driven by one V-belt. Do as follows
to replace the V-belt:
1. Dismantle the cutting unit, see page 52.
2. Loosen the unit frame (1) see page 54, the screw
on the parallelism strut (2) and the two screws on
the cover (3). Lift the protective cover from the
belts.
3. Loosen the spring (4) that tensions the V-belt and
pull the belt off.
4. Attach the new belt.
The belt tightening schedule is located on a decal
on the inside of the protective cover.
5. Check that the belt tensioning equipment is not
jammed or binding and replace the spring.
6. Replace the protective cover and attach the
parallelism strut and unit frame.
7. Attach the cutting unit to the machine, see
"Attaching the cutting unit" on page 46.
