Replacing the V-belt | Tightening the V-belt
Loosen the two clamping screws of the brush container V-belt as shown in the
figure, then push the plate opposite to the direction of travel. Push the plate in so
far that the V-belt, which runs along the groove in the brush container, relaxes as
much as possible.
Fig. 20 - Belt clamping screws
Now lever the V-belt out of the groove, moving it from bottom to top (use a
screwdriver if necessary). Turn the brush element until the V-belt moves up and
out of the groove completely.
Drive belt designation:
SPZ 2137
Please use original fabric V-belts from the authorized dealer only!
Reassemble by following the steps in reverse order.
The V-belt clamping screw must now be readjusted to ensure proper power
transmission from the engine to the brush element. Tension the V-belt with an
appropriate tool (e.g. screwdriver) by inserting it into the grooves shown above
and applying the levering force required for tensioning the V-belt.
Please make sure that you do not overtighten the plate and the clamping
screws, or the bearing of the engine or brush will be damaged.
Put two fingers against the V-belt and try to push it in for approx. 20mm. If
this is possible, the tension is sufficient to transmit the power.
