Maintenance
Check the four (4) carbon brushes for wear - in normal use once
per year - with very intensive use of the bow thruster, e.g. with
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.
- The brushes can be taken out of the holders by releasing the
retaining spring.
