Lyn300 lubrication

[JamieF]

We recently moved into a property with a set of non-working LYN300 24 volt openers. I’ve diagnosed the fault to a failed power transformer and replaced it and the gates now work but they do squeak a bit with the noise coming from the openers themselves. I’ve removed the covers and all appears OK inside with plenty of grease on the drive gears and no signs of water ingress. I can’t see a way to lubricate the threaded rods that extend and retract the pistons. Any suggestions on how to go about doing this?

Hi,

A spray lubricant, such as an application of WD40 should be able to solve this.
