General Maintenance InformationV2015.06_EN
1.1 General Maintenance Information
Cleaning
For an optimal result of the maintenance works, every component that will be disassembled must be cleaned.
Only cleaners which do not damage the components may be used. Especially the cleaning of O-rings and
sealings requires mild cleaners. Always consider the instructions of the respective cleaner.
DT Swiss recommends the following cleaners:
•Motorex Rex
•Motorex Swissclean
•Motorex OPAL 2400, OPAL 3000, OPAL 5000
Use soap water or similar mild cleaners for external cleaning.
Tools
To ensure a damage-free mounting and dismounting of the components, only use the tools which are menti-
oned in this manual. The tools must be in good order and condition.
The usage of differing tools is up to the user. If components are being damaged by the usage of differing tools,
the user is liable.
DT Swiss special tools are precision tools. Damage-free mounting and dismounting of the components can only
be ensured, if the tools are working properly and if the conditions of the tools are perfect.
Always keep the tools in their original packaging or adequate devices to save them from damages.
Expendable Material
If special materials like grease or oil are needed, they will be specified in the table «Required Material» at the
beginning of a chapter. The symbol «» refers to the table «Required Material» in the respective steps.
Environmental Protection
Whenever possible, waste has to be avoided. Waste, especially carbon, lubricants, cleaners and any other fluids
must be disposed in an environmentally compatible manner.
Only print this manual if electronic usage is not possible.
Disclaimer
The operations described in this manual should only be performed by experts. The user is liable for any damage
or consequential damage caused by wrong maintained or wrong installed components. If you have doubts, ple-
ase contact a DT Swiss service center.
