All bearings are self-lubricating ball bearings or bronze bearings. This should not be lubricat-
ed. It is important to ensure that the sensor is about 2 mm away from the engine. This can be
checked with a 2mm thick piece of sheet metal. If necessary, the distance can be readjusted.
The inner side of the sensor is accessible through the open damper with a wrench SW17.
Caution!
Switch off before installation and secure against accidental recon-
nection.
