Sako trigger problem - HELP

[rooboy2]

Have Sako L461 action in .222, 3 out of 5 times when I close the bolt it won't cock. Very frustrating when out varmint shooting. Some friends have suggested that I play around with the screws, but I won't touch what I'm not sure of. Hence my question, does anybody know where I can download any information on how to fix this. I believe that the sear is just not engaging all the time.

Thanking one and all for your help.:confused:
