Air Arms Owners Club

Hi guys
Just purchased a lovley second hand s400 classic,my first pcp! It has had the a/t screw removed and wondered if they are a hard gun to work on?
Want to do service and seal change on the gun but ive only seen 2 videos on you tube,ive tuned crosmans and smk qb78 in the past so know one end of a allen key from the other! Lol
Just wondered if any of you air arms experts have a strip down guide or any tips and advice?
Many thanks in advance.
Regards
Lee
