12.6 V-belt replacement | V-belt tightening
Loosen the two V-belt tensioning screws as shown in the figure and slide
the plate towards the centre of the machine. Push the sheet in until the
V-belt, which runs in the groove of the brush element, relaxes as far as
possible.
Now lever the V-belt from bottom to top out of the groove (possibly with the
help of a screwdriver). Turn the brush element so that the V-belt slides
completely up out of the groove.
BezDrive belt label: SPZ 2137
Please only use original fabric V-belts from the authorised dealer!
The assembly takes place in reverse order.
The V-belt tensioning screw must now be adjusted again so that optimum
power transmission from the engine to the brush element is ensured. The
tensioning of the V-belt takes place with the help of appropriate tools (e.g.
screwdriver), which can be inserted into the above-mentioned grooves, in
order to achieve the force required to tension the V-belt via the lever action.
Please make sure that the plate and the tensioning
screws are not over tightened, otherwise the bearing of
the engine or brush could be damaged.
If you can push in the V-belt about 20mm with two
fingers, the tension is sufficient to transfer the force.
