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.
Fig. 23 - Belt tensioning screws
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.
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.
