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 the wear
limit. If they have, a specialist dealer will need
to replace brake discs.
7.4.9

Electrical cables and brake cables

 Check all visible electrical cables and cables
for damage. If the sheathing is compressed, for
example, the pedelec will need to be removed
from service until the cables have been
replaced.
 Check all electrical cables and cables to make
sure they are fully functional.

7.4.10 Gear shift

 Check the gear shift and the shifter or the twist
grip setting and adjust it as necessary.

7.4.11 Stem

 The stem and quick release system should 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.
 Check for wear and signs of corrosion
(maintain with an oily cloth) and for oil leaks.

7.4.12 USB port

Notice
Any moisture which enters through the USB port
may trigger a short circuit in the display.

USB port and adjust it as necessary.

7.4.13 Checking the belt and chain tension

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.
 Check the chain tension in three or four
positions, turning the crank a full revolution.
 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.
 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.
 If a hub gear is featured, the rear wheel must
be pushed backwards or forwards to tighten
the chain. This should be done by a specialist
only.
