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.

The following maintenance activities may only be car-
ried out by a competent person, see chapter 2.3 -

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.

wire ropes after approx. 25,000 door operations
(open/close movements).
