Hub Gears; Operating The Hub Gears; Shimano 7/8-Speed Shift Lever - Raleigh ebike User Manual

Cleaning
› Whenever possible, avoid using cleaning agents on
the chain. If you use cleaning agents, such as rust
remover, this may wash lubricant out of the chain
which could lead to malfunctions.
› The chainrings and sprockets should be cleaned
regularly using a neutral cleaning agent.
› You should clean the derailleur and lubricate the
moving parts (mechanism and rollers) at regular
intervals.

19.2 Hub gears

This User Manual describes the handling of typical, com-
mercially available gear-shift components of a gear hub on
a city or trekking bike. For other components, refer to the
separate information or enclosed instructions.
If you have questions on installation, adjustment, main-
tenance and operation, please consult a specialist cycle
shop.
If the hub is mounted on the frame, the correct fix-
ing washers must be used on both sides and the hub
nuts must be tightened to the prescribed torque (see
➠ Chapter 30 "Technical data").
If the fixing washers are used on one side only or the
hub nuts are tightened incorrectly, the hub may mal-
function: It could rotate. This could cause the shifting
cable to pull the handlebar to one side and cause a
serious accident.
38 I General User Manual
The gears can be changed when the pedals are turn-
ing. Very occasionally, the hub may produce a harm-
less noise which is caused by its internal cogs and
stop notches.
If you encounter resistance when turning the wheel,
the brake pads will need to be replaced or the hub
will need to be lubricated. This should be done by a
professional bike workshop.
If the chain jumps off the the sprockets when you are
riding, the slack in the chain must be taken up imme-
diately. If there is no further scope for adjustment, the
sprockets and chain must be replaced.
