6 Maintenance / checks
6.1 Maintenace activities – operator
The following points must be checked and carried out
after the installation of the door and every 6 months:
• Always grease the roller axes after
approx. 5000 door actuations. Clean horizontal
rail pairs.
• Do not apply oil on the lock cylinder. In case it
does not run smoothly enough, treat with
graphite spray.
• Ensure sufficient ventilation (drying) of the door
frame. Water drainage must also be ensured.
• Protect the sectional door from caustic and
aggressive agents such as acids, lyes, thawing
salts etc. Only use mild household cleaning agents.
• Steel-filled sectional garage doors are coated
with polyester at the factory. Any paintwork on
site must be applied within 3 months from
delivery using 2C epoxy primer containing
solvents and, once hardened, standard paint.
• Touch up the paint at intervals as required by
local environmental and atmospheric conditions.
6.1.1 Cleaning
We recommend wiping the door regularly with a soft,
damp cloth. If necessary, use a mild cleaning agent
or soap with lukewarm water. Avoid using any polish-
ing agents or abrasive or organic solvents/cleaning
agents. Before cleaning, flush the door and glazing
thoroughly with water to avoid scratches caused by
dust particles.
6.2 Maintenance activities – competent
person
The following maintenance activities may only be car-
ried out by a competent person, see chapter 2.3 -
Personnel qualifications.
• Check the door in accordance with the test
instructions.
• Check screws and clamping connections for tight
fit and retighten if necessary.
• Check wearing parts (springs, wire ropes etc.)
and replace with original spare parts, if
necessary.
• Make sure that the spring tension is correct. If it is
necessary to adjust the spring tension, proceed in
accordance with the assembly instructions.
• Replace multiple spring assemblies and double
wire ropes after approx. 25,000 door operations
(open/close movements).
This is equivalent to approx.:
