• Keep track free from obstruction and excessive dirt or water.



• Inspect all fixing bolts for tightness every six months, including those securing brackets. Tighten if necessary.



• All hangers are fitted with sealed lubricated ball-bearings or plain bearings, which require zero greasing.

• If doors ‘settle’ and door clearance is reduced, causing friction, raise the door by the hanger adjustment nuts.



• Guide roller and guide channel must be kept clear and free of obstructions.
