M 12 hexadecimal head bolt or recessed head bolt (commercially available)
and an appropriate wrench or Allen wrench
Unplug the power cable from the power socket before opening the device!
Procedure for replacing the V-belt:
The manufacturer, daum electronic gmbh, will not be liable for any damages arising
as a result of negligence while changing the V-belt!
The V-belt is easily replaced. This maintenance operation can be performed by users with manual skills.
If you have difficulties obtaining a replacement V-ribbed belt for your ergo_bike,
you can order one directly from the manufacturer, daum electronic GmbH.
The driving surfaces of the drive and the V-belt pulley are covered with a rubber layer by the manufacturer.
This favors the development of an optimal fitting of the V-belt into the grooves of the driving pulley
during the first 500 to 1000 kilometers.
During this fitting-in process, the belt will loose the excess rubber, which will be visible in the form of black
powder deposits. You can remove this deposit using a small brush or a vacuum cleaner.
Remove the protective cap (1) of the axle center.
Loosen the screw attaching the pedal rod (2).
(6mm Allen wrench)
Screw in an appropriate M 12 bolt, with a hexadecimal
or recessed head, into the thread of the pedal axle
until the pedal comes off the axle shaft.
(see small figure).
Hold the pedal firmly and remove it.
Loosen the 7 screws (3) on the right side
cover (RSC).
Carefully remove the side cover.
Press on the belt tensioning roller (31c) against the
spring tension to loosen the V-belt tension, and then
pull the belt from the pulley (25) and drive shaft (28c).
Install the new V-ribbed belt by going through
the same steps described above in
the reverse sequence.
