9. Maintenance
Defective door systems and safety equipment
result in the risk of injury.
For your safety, you should comply with the
recommended maintenance intervals for your
door system, including all safety equipment.
Maintenance interval:
Have the door system inspected by a specialist
company before commissioning and then as
required, but at least once a year.
Regular checks of wearing parts:
There is a risk of injury due to defective or worn
components.
Check the system therefore regularly for signs of wear,
damage or lack of balance of the door.
Do not use the door under any circumstances if repairs
or adjustments need to be made, as a faulty or imbal-
anced door can lead to injuries.
Check all:
◆ screwed connections to ensure they are tight
◆ cables for damage
◆ springs and fixing parts
There is a risk of injury due to the tightly
tensioned door springs.
◆ Never attempt to replace the door springs
yourself.
◆ Have all work on the door mechanics and springs
carried out by a qualified engineer.
