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.
