I can't change the blade on a B & D miter saw.

How do I lock the motor to remove the blade? Are you *absolutely* sure you're turning the arbor nut in the right direction to loosen it? Yes! And I did try both clock and counter clock wise. |

Try an impact driver--one of them spring-loaded, hit 'em w/ a hammer thingies. Sounds like perhaps original owner may have used it w/o having fully tightened blade and the starting torque can really overtighten and slightly stretch bolts. (DAMHIKT but I'll tell the story anyway--got interrupted while changing blade on Dad's little contractor saw while building the kitchen cabinets. Forgot where was when got back and just automatically turned it on to go. Spun that sucker on so tight was a _major_ pita when did need to change next time) My DeWalt has an armature locking pin; don't know B&D well enough but look carefully, it's a pretty small little rod that could be overlooked. If have a buddy or know some service shop well, maybe could drop by and borrow an impact wrench or get them to do it for you, maybe??? -- |
