you should be able to release it with a flat screwdriver. you should see something that looks like a wheel where the chain brake locks to the brake handle when you put the cover back on. you should be able to twist that wheel and unlock it that way.
Go to http://www.milacalawn.com/parts.asp and look for the bolt that hold the brake.usually the bolt is located in the chain plate that has a large groove in order to adjust the chain.
Remove the drive cover plate, then inspect the internals of the brake assembly. Either the brake band is damaged or possibly full of debris that prevents release of the brake. Does the brake lever actuate when off of the saw? Clean the entire assembly with compressed air and check the brake 'toggle' action. Look for damaged components. The brake mechanism must be released to reinstall the cover. Clean and check the drive end oil passages for any plugging. When the cover is installed with fasteners finger tight, adjust the chain until it comes up to the lower run of the bar, but not so tight that it can't be pulled by hand. Tighten the nuts and recheck tension. Check for proper oiling by holding the bar tip near a piece of cardboard and running at speed for a few moments--it should throw off a light line of oil onto the board. Hope this helps!
It sounds like the chain is too tight. Loosen up the tension on the chain by turning the tensioning screw located on the end of the saw where the bar goes out.

See Detail A, pn 503 89 08-02. You can use a Crescent Wrench on one of the ears (left end) to reset it. With the cover positioned with pn 503 89 08-02 in the upper left rotate it CW until it nests, to reset it.

I will wager you will NEVER again remove the cover with the brake set. Me either! Good Luck. HTH Lou
hi , by what your describing i think the chain brake has came on , you will have to reset this , its a good idea to carefully hold it in a vice and try to manually reset it
sounds like you removed it with the brake on? Start by removing the bar and chain, then put the cover on and tighten the nots only hand tight. then push the cover in at the point where it connects to the brake handle, then pull the handke back with your left hand while holding it in, That will reset the brake. Then reinstall the bar and chain, and your good to go.
