Cleaning and servicing
7.4.5
Checking the brake discs for wear
Check that the brake disc is no less than
1.8 mm at any point.
The brake discs have not reached their wear
limit yet; brake discs need to be replaced if
they have. Contact your specialist dealer.
7.4.6
Electrical cables and brake cables
Check all visible electrical cables and cables
for damage. If the sheathing is compressed, a
brake is defective or a light does not work, the
S pedelec must be removed from service until
the lines or cables have been repaired. Contact
your specialist dealer.
7.4.7
Gear shift
Check the gear shift and the
shifter
or the
twist
grip
setting and adjust it as necessary.
7.4.8
Stem
The stem and quick release system must be
inspected at regular intervals. The specialist
dealer should adjust them if necessary.
If the hexagon socket head screw is also
loosened, the headset backlash also needs to
be adjusted. Medium-strength thread locker,
such as Loctite blue, then needs to be applied
to the loosened screws and the screws
tightened as per specifications.
Contact your specialist dealer if there is any
wear or signs of corrosion.

USB port
7.4.10 Checking the belt and chain tension
1
Check the chain tension in three or four
positions, turning the crank a full revolution.
Figure 40: Checking the chain tension
2
If the
chain
can be pushed more than 2 cm, the
chain
or
drive belt
will need to be tensioned
again by the specialist dealer.
3
If the
chain
or the
drive belt
can only be pushed
up and down less than 1 cm, you will need to
slacken the
chain
or the
drive belt
.
The optimum chain tension is achieved if the
chain
or the
drive belt
can be pushed a
maximum of 2 cm in the middle between the
pinion and the toothed wheel. The crank must
also turn without resistance.
4
If a hub gear is featured, the rear wheel must
be pushed backwards or forwards to tighten
the chain. Contact your specialist dealer.
5
Check the handlebar grip is firmly in position.
Notice
Any moisture penetrating through the USB port
may cause a short circuit in the
display
.
Regularly check the position of the
cover on the
USB port
and adjust it as necessary.
Notice
Excessive chain tension increases wear.
If the chain tension is too low, there is a risk that
the
chain
or the
drive belt
will slip off the
chain
wheels
.
Check the chain tension once a month.
