10 Cleaning, maintenance and servicing
10.1 Changing the thread rolls
Check the rolled profile exactly after changing the rolls. If in particular the workpiece
major diameter is not correct, compensate for this by adjusting the head setting, see
Chapter 8.
ATTENTION
It is only permitted to use thread rolls with the same roll set number
Make sure to apply a coat of molybdenum sulfide
(e. g. Molykote) to the roll hole and axes (3).
Retighten the cap screw (25) after approx. 100 rolling operations!
10.2 Maintenance intervals
The required maintenance intervals must be observed to ensure the proper function of
the rolling head. The cleaning and maintenance intervals will need to be shortened if
the rolling system is used under difficult conditions.

Check the washer (ET-15) for even wear. Replace
both washers when:
■ the thickness of both washers differs by
> 0.05 mm l 0.02 inch from each other
■ for T18 the thickness of a washer is less than
0.45 mm l 0.018 inch
■ for T27 the thickness of a washer is less than
