5 Maintenance
The maintenance of L&L door operators is by their constructive approach to a minimum. Components,
which are subject to an operational wear, are in regular maintenance involved.
WARNING:
During the maintenance work is essential to ensure that the drive cannot be turned on and
that no parts exposed inadvertently come under electric voltage. After end of these
measures available protective facilities and security facilities in the door operator are to be
installed again.
5.1 Maintenance Sinus Drive
A service should be done at approximately 1,000,000 cycles. One cycle corresponds to one extension
movement plus one retraction movement of the Sinus Drive (a high-performance lift can be presumed to
complete approx. 800,000 cycles per year).
As part of servicing operations the Sinus Drive is to be subjected to a visual inspection for impurities and
damage. Any impurities and/or damage are to be rectified before greasing. If major deficiencies or soiling
is discovered, then appropriate countermeasures are to be taken.
6 Waste disposal
With the disposal the appropriate regulations are to be followed:
-
oil according to waste oil order (e.g.. no mixture of solvent, cold cleaner or varnish remains)
-
components for utilization distinguish between:
o
iron scrap
o
electronic scrap
o
aluminum
o
multicolored metal (worm gear, drive winding)
