Hello! My husband has an issue with jonsered 630. Does anyone know how to put chain brake parts back together. He put it together once but it seems that the handle brakes in wrong direction. Is there a manual or something or a picture? Sorry my bad english 🙈

I'm currently carrying out a bit of research into the safety of chainsaws for my MEng Electrical and Electronic Engineering Degree. Chainsaws cause a lot of injuries every year and can seem a bit dangerous to the beginner. I am aware that there are safety mechanisms in place such as the chain brake, operated by hand or via inertia, however people still get injured. It would appear that naturally applying the chain brake by your left wrist in a dangerous situation comes with training and/or experience. My understanding of the inertial brake is that it requires an reactive force by the user, which again comes more naturally with training and/or experience. Would an electronic device that can sense abnormal movements (sudden changes in angle or position) and apply the brake quicker than the novice user make the chainsaw a more welcoming tool for the beginner? I understand that the chainsaw may still hit the user, however injury would be reduced by a multitude as the chain will have stopped. I am open to any comments or further advice.

Hi chaps. I got myself an MS341 a couple of years ago. It's had some use but nothing like on a daily basis. However- Since I bought it I thought the chain brake was a bit hard to engage but never worried too much about it. Been using it the last two days and its gotten loads worse - It's now so stiff, the back of my hand is blue. I'm having to use the heel of my palm to put it on which is far from safe... Anyone had this happen? Is it just gunked up? Anything I can do? Thanks!
