hire vessels, once every two months.
- Remove the protective cover from the relay and then the
protective cover to the brushes.
- Clean the carbon brushes, the holders and the collector.
(Blow away the dust coming off the brushes.)
- Check the length of the carbon brushes and replace before
the minimum length (L min) is reached. Also check the col-
lector for excessive wear.

retaining spring.
