CAUTION
Risk of injury!
If you do not have the necessary
technical knowledge or do not carry out the
maintenance correctly, you could be injured.
- Wear protective gloves.
- Keep your fingers away from moving parts.
- Make sure that your fingers do not get
trapped.
NOTICE
Danger to the environment and risk of damage
to property. Oil and grease can pollute the
environment. Excess oil and grease can make
your clothes and other items dirty while you are
riding.
To reduce your impact on the environment,
use only biodegradable lubricants. Place a tray
under the bike to catch drips of oil.
Do not put any remaining oil or grease in your
household waste bin. Dispose of it at a recycling
centre.
WARNING
Poor braking.
Oil or grease on the brake pads
and brake discs will reduce the friction
coefficient and the effectiveness of the brakes.
Make sure that there is no oil or grease on the
brakes.
Even if you maintain your chain regularly, it
will still wear out. Chains will generally last for
around 800 to 2500 km or for 40 to 125 hours
of use.
NOTICE
Replacing your chain regularly can extend the life
of your chain rings and cassettes.
To check the condition of the chain, pull it away
from the chainring with your thumb and first
finger. If you can pull the chain a long way away
from the chainring, it is very stretched and needs
to be replaced. Your ROTWILD authorised dealer
can carry out a more accurate check of your chain
using special tools.
Fig. 19: Checking the condition of the chain.
Only use original spare parts that are approved
by ROTWILD when replacing your chain. Choose
the right chain for your dérailleur.
WARNING
Sudden loss of power and drive. A worn chain
can suddenly break or jump off the sprockets.
The resulting sudden loss of power and drive can
cause a crash. Check the condition of the chain
regularly and replace it if necessary.
