2.2

Misuse

Exit 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 exit device or into the
striker.
„ The exit device 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 latchbolt or deadbolt is used to keep the door open.
„ Exit device 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 clearance increases or decreases as a result of hinge readjustments or lowering of the door leaf.
„ A double-leaf door is opened by 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 frame when the door closes.
„ The lever handle and cylinder are operated simultaneously.
2.3

Product maintenance

Locking systems should be checked at least four times a year to ensure fitness for use. The exit device must be
checked to ensure that it is in proper working order.
Perform the following routine maintenance checks and document them accordingly:
„ Inspect and actuate the panic exit device and make sure that all parts of the exit device are in a perfect operating
condition.
„ Make sure that the keepers are not jammed or filled with dirt.
„ Make sure that no additional locking devices have been fitted to the door at a later point in time.
„ Verify that all system components still correspond to the list of approved components originally supplied with the
system. Have the system serviced to its proper condition at regular intervals.
„ Make sure the fixing materials are properly tightened and retighten according to regulation if required.
„ Lubricate all moving parts, locking points, and the rear of the central and additional latchbolts with a non-
resiniferous grease (e.g. LUMO Special Grease 8559/1 of Zeller+Gmelin).
We recommend an additional monthly functional check of the panic exit device. Only cleaning and care agents that
do not affect the corrosion protection of the hardware parts may fundamentally be used.
