• Wall switch (if this accessory is installed): Press the pushbutton until

Maintenance

Check the system often, especially cables, springs and fasteners,
for signs of wear, damage or lack of balance. Do not use if repair
or adjustment work must be performed, because an error in the
system or an incorrectly balanced door may cause injury.
Once a month:
• Check automatic safety reverse again and reset if necessary.
• Operate door manually. If the door is unbalanced or stuck, please
contact the service centre.
• Check for complete opening and closing of the door.
Where appropriate, readjust limit switches and / or power.
Twice a year:
• Check the chain belt tension. For this, first disconnect the carriage
from the drive. If necessary, adjust belt tension.
• Lightly lubricate the guide rail with standard grease (lubrication).
Once a year (at the door):
• Lubricate door roller, bearings and joints. An additional lubrication of
the door opener is not required.
Do not grease the door rails!
Limit switch adjustment and force regulation:
These settings must be checked and undertaken properly during the
installation of the opener. Due to weathering, minor changes can occur
during operation of the opener that need to be addressed by a new setting.
This can particularly happen in the first year of operation.
Follow the instructions for setting travel limits and force (refer to section 23
and 33) carefully and re-check the automatic safety reverse after each
resetting.
