Check all fixings are secure and make a visual check for faults and wear.

Check the correct functioning of the door; that the door closes properly into the frame and the latch, if fitted, secures the door firmly in position.

Make any adjustments as necessary for closing power/closing speed and latch action.

Lubricate all external moving parts on the arm and pivot linkage.

Ensure the closer is clean and free from all debris.

For electromagnetic hold open closers ensure the system is operating correctly by using the test button located on the underside of the track.
