Closer Maintenance
WEEKLY
Release the door from the fully open position and ensure that it closes fully into
the frame. Ensure the latch (if fitted) engages fully into the strike plate. Repeat the
process a few times from different angles of opening to ensure the door closes
consistently each time.
Check and adjust the closing and latching speeds if necessary.
Check that the door or hardware does not come into contact with the door frame
or the surrounding structure.
QUARTERLY
The fixings of the closer body and the bracke are subject to stress and should be
checked carefully to make sure they are tight.
Periodically apply a little light machine oil to the moving joints of the arm and
bracket.
Check any fire and smoke seals to ensure they do not foul the action of the door.
Check for any loss of fluid from the door closer body which would indicate a
failing device.
Clean the closer body, arms and bracket if necessary following the guidance on
“Care of Finishes” on page 16 of the ‘Service & Maintenance Guide’.
FIRE DOOR APPLICATIONS

including the door selector if used on a double door arrangement, should be
checked in accordance with standing periodic fire testing procedures.
