2.2 Misuse
Devices are being used incorrectly, i.e., not for their intended use, if, for
example:
Problem-free use is prevented by inserting foreign and/or unintended
objects into the lock or into the striker.
The locking system is manipulated in a such way as to involve structural
or functional changes or in any other way not expressly permitted in the
assembly instructions.
Contrary to its intended use, the ejected latchbolts are used to keep the
door open.
Locking elements cannot function properly as a result of improper
installation or subsequent treatment, such as painting.
Unintended loads beyond normal manual force are applied to the handle,
e.g., lifting and carrying the door by the handle, ramming or kicking the
handle.
Inappropriate locking mechanisms are used, e.g., wrongly dimensioned
or incorrectly adjusted closers.
The specified door gap changes as a result of hinge readjustments or
unintended lowering of the door.
A double door is opened via the passive leaf although not designed and
approved for this.
A double-leaf door not equipped with a carrier bar is opened via the
passive leaf and is restrained as a result.
The function of the door leaf coordinator in a double-leaf door is
bypassed.
Objects or extremities are put between the door leaf and door frame
when the door closes.
The lever handle and cylinder are operated simultaneously.
