Inspection and maintenance works, replacement parts

GU-SECURY Automatic with A-opener / A-opener servo must only be operated with power
supply units meeting the minimum requirements of the lock (see "Technical data")
Any warranty claims for damage caused by non-observance are rejected.
The serviceability of the locking system must be verifi ed at regular intervals. For doing so,
check all fi xing points and retighten screws, if required.
In order to avoid that the mechanical properties of the lock – especially with regard to key,
handle, and latchbolt movement – are affected by dirt, it is necessary that the lock is inspected
and lubricated with non-resinous oil at least once a year.
The A-opener itself is maintenance-free.
