A checking of the circumferential backlash and a visual check of the eleastomer part must
be effected after 3000 operating hours for the first time, after 6 months at the latest.
If you note an unconsiderable or no wear at the elastomer part after this first inspection, the
further inspections can be effected, in case of the same operating parameters, respectively
after 6000 operating hours or after 18 months at the latest.
If you note a considerable wear during the first inspection, so that a change of the
elastomer part would be recommended, please find out the cause according to the table
„Breakdowns“, as far as possible.
The maintenance intervals must be adjusted according to the changed operating
parameters.
