Stihl 020 AV help!!

[LumberJake]

Hi everyone! I was working today with my 020 AV top handle chainsaw and then at the end of the job I did a once over on my saw. The thing that I have created this topic about is that when I looked over my saw I realised that a screw was missing. (See photos). I have placed a 18mm M5 screw in it's place, is this the right screw?? Another thing is what is this screw for??. There is another screw like it (see last photo) on the top aswell so I'm guessing they're linked?

 

I'd be greatful for any help you can give.

 

Cheers, Jake

The screw near the back holds the case to the cylinder and the one at the front does the same job holding the casings together

Is this the right type of screw for the job? 18mm M5?

Mine pretty much vibrated itself apart, but it kept going! Strong old saws!

Mine has been doing that recently too!! First it was just the top screw at one time. Then I was using it the other day, the side plate started to come off, the exhaust box started come off too and the top screw started coming out again!!!

They need to be locktite in.

 

Failing that some araldite works well.

Yeah I need to order some locktight. I also changed the top screw to a bolt with a small washer and that is staying in now.
