Mortice, Key in Knob and Key in Lever Locks

Lock Mechanism

At twelve (12) monthly intervals, the internal lock mechanism should be lubricated by an aerosol lubricant.


Cylinder Mechanism

Spray a small amount of aerosol lubricant into the keyway and insert and withdraw key 3 to 5 times. Wipe the key blade each time to remove any debris that may have been in the keyway.

In harsh environments it is recommended to maintain the cylinders on a six (6) monthly cycle.


Latchbolt Mechanisms

At twelve (12) monthly intervals, the internal latchbolt mechanisms should be lubricated by an aerosol lubricant.

In high corrosive environments it is recommended that the spindles and cams should be sprayed with a lubricant or smeared with white lithium grease for protection when servicing locks.


External finishes

All external lock components should be cleaned with a dilute solution of a mild liquid detergent in warm water. Avoid hot water. Use a soft clean cloth to clean the surface, a gentle abrasive cloth or soft bristle tooth brush may be used to remove ingrained grit.

After cleaning, rinse with clean water or a clean damp cloth, and then dry.

Do not use bore water due to its high mineral content, as it can stain the finish and progress to long term finish damage.

Soft finishes such as Brass, Polished brass, PVD gold, chrome plate, etc. Need Special care. Dirt or other contaminants must not be allowed to build up on the surface.

Under NO circumstances should any cleaning product be used. The cleaning product may contain solvents which may damage the protective coating.

These finished should only be wiped with a soft cloth and then polished with silicone based spray. This should be done approximately every two (2) months.

For Oil rubbed bronze use furniture oil or similar.


Door Closers

After the first three (3) months of usage, check all screws and fixing points, tighten if necessary.

At twelve (12) month intervals, check all screws and fixing points, tighten if necessary. In the case of adjustment arms, the adjustment screw on the arm should also be tightened.

At any time during the life of the closer, the closing cycle adjustment valves can be varied to best suit the working environment of the door. If however, it is constantly necessary to increase the closing speed or the closing force because ‘it seems to be slowing down’ the door hinges need to be examined as they may be worn and causing ‘binding’ which will over-work the closer.

If the closer cycle valves are adjusted, open and close the door four times to allow the valves to set in their new position. If the cycle still needs to be adjusted, commence the full procedure again.
