I have a pair of electric gates with motors badged as Telcom PH 50. They're about 15 years old I think.
Recently the speed of one gate has been getting consistently slower than the other, and this is causing a problem when they close (i.e. they don't overlap properly).
Is there any (diy) thing I can do about this? (i.e. adjust something, top-up oil? etc.)
Thanks & regards
