Bedienungs- und Wartungsanleitung für Handschweißextruder Serie HSK18 RSX
We recommend further eliminating eventually sticking deposits from the screw, for
ex. by means of a brass brush. When cleaning the screw please take special care
not to damage the chrome layer!
Also retighten all screw connections. Missing or faulty parts must be replaced
immediately.
Replace carbon brushes not later than when reduced to 7 mm length. We
recommend to control the carbon brushes regularly every two weeks, as abrasion of
these brushes heavily depends on the prevailing operating conditions.
After insertion of new brushes it has to be checked whether they can be easily
moved in their holding device.
If, even after insertion of now carbon brushes, a strong commutation sparking occurs
within the collector area, the collector will have to be drawn off. Otherwise there is the
danger of heavy wear on the carbon brushes.
