7.9.16 Slip ring bodies (optional)
A slip ring body is located on the rotary
transmission to supply power to the undercar-
riage. The slip ring body is sensitive to mois-
ture. A layer of oxide, which inhibits the flow of
current, can form on conducting surfaces.
Electrical consumers in the undercarriage will
no longer receive an adequate supply of elec-
trical current, which can result in malfunctions.
To counteract this effect, the following jobs
should be performed every 500 operating
hours:
Unscrew the lock nuts and remove the slip
ring body housing. Clean oxidation off the slip
rings (use a cleaning spray if necessary). Re-
place worn out (eaten through) cable lugs and
spray "Cramolin" contact spray on all slip ring
elements.
Set the housing in place and tighten each lock
nut to the same extent.
