Intro and help

[Tomsdad]

Hi everyone. Moved into a house which had electric gates fitted 2 years ago.  Manufacturer is Roger Technologies. They are swing gates with underground motors. I want to service them myself however manufacturer is not being helpful with any information. Simply offering contact details of  “service engineers” in my area. I am very hands on. Is it possible to service these myself and more importantly where can I get information on what needs doing?
Thanks in advance for any help.
