Cleaning and maintenance
Before any maintenance, cleaning and related
maintenance work, the mains supply plug should be
pulled out. Danger from electric shock!
Maintenance of the door opener
A proper installation ensures the optimum performance of the door
opener with minimum maintenance. An additional lubrication is not
required. Gross dirt accumulation in the guide rail may impair the
function and must be removed.
Cleaning
Clean the drive head, wall switch and handheld transmitter with a soft,
dry cloth.
Do not use liquids.
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 tension. For this, first disconnect the carriage from
the drive. If necessary, adjust chain 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 set-
ting. This can particularly happen in the first year of operation.
Follow the instructions for setting limit switches and traction (see 9.1)
carefully and
re-check the automatic safety reverse after each
resetting.
