CAWI Key-Operated Lock 2648 Optima
CAWI Key-Operated Lock 2648 Optima
The lock may be operated only with the keys associated with
the particular lock. Inserting and attempting to operate the
lock with any other keys may cause damage.
The key is to be inserted into the lock so that the lowermost
notch, present on only one of the bits, points toward the
bolt.
When the lock secures a door hinged on the right it will be
necessary to rotate the key clockwise to open the lock. Rotate
the key counterclockwise in locks securing doors hinged on
the left. Secure by turning the key in the opposite direction.
The key is captive and can be removed only when the lock
is secured. The key will always have to be turned all the way
to the stop. No excessive force (and no tools) may be used
to turn the key. A qualied service technician will have to be
called in case of malfunction.
cawi locks may be dismantled only by persons who
have been trained by cawi as the guarantee would
otherwise be invalidated.
In the interest of safety, the key should never be left
unattended in the lock. It is also necessary to store the
keys in a secure place and to make them accessible
only to authorized persons. The lock is to be replaced
immediately if a key is lost.
Important note:
The lock requires no maintenance when used in a
residential or ofce environment. It is advisable to have
the lock inspected for security and proper function after
about 10,000 operating cycles. Such inspections are to
be carried out by personnel trained by cawi.
IMPORTANT: Do not use lubricants or any other sub-
stances in the lock.

Then use four steel machine screws (M6 or the corresponding
inch threads) to afx the key-operated lock so that it is perma-
nently and securely attached. Prevent spontaneous loosening
of these screws. It is advisable to insert a lock washer under
each of the screw heads. In order to avoid malfunctions, the
mounting screws may be tightened down only to a maximum
torque of 10 Nm.
The bolt may not be subjected to stress or strain after
installation.

be covered by any components.
Do not use lubricants or any other substances in the
