8.5 Drum coating
A drum coating (e.g. rubber coating) that was applied retroactively can cause the drum motor to overheat. For some
drum motors, there may be restrictions concerning the thickness of the drum coating.
To avoid a thermal overload, the required output should be multiplied with 1,2.
Please contact Interroll concerning the type and maximum thickness of a drum coating if you want to apply
one.
8.6 Sprockets
Tooperatelinkbeltswithsprocketsrequiresthatasucientnumberofsprocketsareattachedtothedrumshellin

the tube length (SL).
