7 Maintenance and Cleaning
The lock has been factory lubricated for life and is maintenance free. The use of
other lubricants is not permitted and will void the warranty.
This lock contains electromechanical and electronic components that are subject
to wear and tear depending on use and on-site installation conditions. The
manufacturer has no influence on these factors. As a result of this wear, the lock
may fail at the end of its normal service life.
Maintenance and cleaning

As needed: Using a dry cloth, polish the faceplate and strike

Check for:
