For couplings which are classified in category 3G or 3D the operating and assembly
instructions that are usual for standard operation apply. During the standard operation
which has to be subject to the analysis of danger of ignition the couplings are free from any
ignition source. Merely the temperature increase produced by proper heating and
depending on the coupling type has to be considered:

A checking of the circumferential backlash and a visual check of the laminae package must
be effected after 3,000 operating hours for the first time, after 6 months at the latest. Except
for centered, stiff connecting flanges (e. g. bellhousings).
If you note an unconsiderable or no wear at the laminae package after this first inspection,
the further inspections can be effected, in case of the same operating parameters,
respectively after 6,000 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 laminae
package 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.

A checking of the circumferential backlash and a visual check of the laminae package must
be effected after 2,000 operating hours for the first time, after 3 months at the latest. Except
for centered, stiff connecting flanges (e. g. bellhousings).
If you note an unconsiderable or no wear at the laminae package after this first inspection,
the further inspections can be effected, in case of the same operating parameters,
respectively after 4,000 operating hours or after 12 months at the latest.
If you note a considerable wear during the first inspection, so that a change of the laminae
package 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.
