You'll have to release the brake with the cover off the saw. You just need to find a way to brace it well enough.
If you really can't do this, then it suggests your chainbrake is faulty, of ath the very least not adjusted right.

I have the same model chainsaw with the same fault. The brake is not releasing when the brake handle is pulled right back. I can only run mine if the brake handle is pulled back to the main handle with a tyrap - defeats the object of the auto-brake completely. Design fault I reckon.

Mine did this when nearly brand new. You likely have a nasty jam of oil and sawdust stuck between the chain brake and the flywheel. It can be loosened by either careful prying of the case or precise shots of carb cleaner up in the housing. While you are in there look for a buildup of oil around the chain brake connection to the kickback paddle.

my guess is that you have a crack or a hole in one of your fuel lines. this is very common in chainsaws and weed eaters because they are used very little and sit for a long time. try checking this and repair if necessary. let me know if this works.

You will need to release the brake by applying a very heavy screwdriver to the + shaped part of the brake coupling. Check the action of the brake handle and duplicate it at the the +. Hope this helps!
