Is anyone familiar with this, and know of a way to get past it? There doesn't appear to be any way to get in there with a tool of any kind - no exposed screw or bolt heads that I can see. Took it to my local Ace Hardware (where I usually get the chain sharpened), and they were baffled. I hate to even try taking it to Sears - they'll likely charge me a ton to repair it, and the saw only cost $150 to begin with. It's a good saw, otherwise - perfect for the light usage I give it.
