Trigger Mechanism Maintenance?

Hi, I have a hatsan MOD125 sniper that I want to service myself for the first time. I want to degrease and re oil the trigger mechanism, but cannot find any info on how to do so anywhere. So my three questions are:

1. What is a good degreaser spray to use?

2. What is a good oil/ grease to use, or should I contact hatsan for the right one?

3. Any special directions to do this, or do I just grease everywhere? (Or should I contact hatsan for this? lol)

Thank you!
 
Just use some acid free grease that you can buy in any gun store for the moving parts. Keep the rest dry, or just the thinnest possible amount of gun oil if you shoot under wet conditions. The amount of grease should be minimum, the more you put on it, the higher the possibility your trigger fails on you at some point, resulting in unwanted discharge even. Watch out for springs that might jump on you, when cleaning.

Oh, and don't use degreasers, that stuff's aggressive. Just use a dry fibre-free cloth to clean the trigger. It ain't rocket science, and you'll learn along the way. Good luck, and good shot!
