These two cardboard sheets were for the first and second inspection and had to be completed as a warranty card from the garage.

The bike should always be driven first in order to identify defects while driving.
Then the oil changes were made with the engine still warm, as the warm oil flowed better.

In the first inspection after 500-1000 KM all oils were changed.


In the second inspection after 2500-3000 KM only the engine oil was changed. The other oil levels were only checked.
However, during this second inspection the oil pan was also removed to clean the filter hose.
The carburetor throttle was removed too, which so far prevented a drive at full throttle.

Each of the inspections cost 12 Reich-marks. Which corresponds to a value of about 80 euros today.

Consequently according to the manufacturer's data the bike had to be driven gently until a mileage of 2,500 KM.

How long did you treat your newly rebuilt engine gently?

All equipment was recorded in theis booklet.
