9.1 Maintenance of the speed module

Depending on ambient conditions, the slotted disc on the rotor and the
associated sensor optics on the stator may become dusty in the course of
operation. This makes itself felt as a change of polarity in the display. If this
should happen the sensor and the slotted disc must be cleaned.
1. Clean the slotted disc using compressed air (up to 6 bar).
2. Carefully clean the sensor optics using a dry or spirit–moistened cotton
wool stick. Never use any other kind of solvent.
