3.10 Fitting the covers
Some versions of universal worm gear units are delivered as standard with a plastic cover cap. The
cover cap protects the radial shaft seals against the entry of dust and other contamination. The cover
cap can attached on the A side or the B side. It can be removed by hand without tools.
Damage to the expansion elements of the cover cap
• Do not jam the cover cap when pulling it off or attaching it.
Pull the cover cap off vertically prior to the installation of the universal worm gear unit. After completing
the fitting, attach the cover cap onto the right side by attaching the expanding elements into the
threaded holes on the output flange.
