11.5 Changing the V-belt | Tensioning the V-belt
The V-belt can be changed easily and without tools. To do this, tilt the
machine backwards so that the underside of the machine is clearly vis-
ible. Important: the cleaning start lever must not be pulled. Now the belt
can be pulled out of the pulleys, past the guides. When inserting the new
belt, make sure that it is guided exactly like the old belt. It is especially
important that the belt is centred in the tensioner pulley so that it works
properly.
Now lever the V-belt out of the groove from the bottom upwards (possibly
with the help of a screwdriver). Turn the brush element so that the V-belt
slides completely upwards out of the groove.
Drive belt designation: XPA 1220
Please use original belts from an authorised dealer only.
