Does my AL-KO Secure system require maintenance?
The design is virtually maintenance free but there are a couple of things that you can do to keep your AL-KO Secure in peak condition
- A small squirt of WD40 into the barrel lock periodically will keep it lubricated.
- Some water barrier grease (such as Vaseline) over the external walls of the barrel lock will stop water ingress between the receiver and the lock during storage.
Why does my barrel lock stick in the insert?
A barrel sticking is usually due to a residue on the barrel.
If this residue is red it is probably rust and you should the AL-KO Service Department on 01926 818500 for advice.
If the residue is white/grey/black then it is ‘wet storage stain’. This is zinc hydroxide and is caused by the lock being wet (due to condensation perhaps) and not drying out properly. The zinc in the coating reacts with the moisture and forms this white/grey powdery substance.
The white/grey powdery substance can be removed using a "Scotchbrite" pad - the green plastic type of pan scrubber. Rub the pad over the affected area until it is removed, then smear some water barrier grease - such as Vaseline - over the exterior of the barrel lock. This will prevent water ingress in the future.
I can't screw my locking bolt into the receiver fully.
The receiver may have been cross threaded or there may be a build up of deposits on the thread. You will need to re-tap the receiver withb the appropriate tapping tool (20mm tap/2.5mm pitch).
Contact AL-KO to arrange for loan of the tapping tool.
