Model 5515 skilsaw changing the blade got the blade off but can't tighten the bolt because the motor keeps turning there is no lock button to told the motor to tighten the bolt what can I do.

SOURCE: Where is the blade lock button on a skilsaw 5150 2

First, there is no blade lock button on the Skil model 5150. I called the Skil customer service and they emailed me the exact manual for this circular saw. The method I used to loosen a VERY TIGHT blade stud was: spray with WD-40, imbed the blade in scrap wood, set Skil wrench (usually found in back of foot under handle) on so it could be struck going in counter-clockwise direction. Use hammer to strike handle of wrench a couple of times. To replace blade, finger-tighten blade stud, then use wrench to tighten 1/8 turn or (45°).

SOURCE: how do you tighten the

SOURCE: How do I change the

Here is what you do, this is common on some skill saws, you of course make sure is unplugged, get your self a stick ( like a small broom handle type, or a piece of 1 by 2 chuck or wood, or anything of about that size. Put saw on its side, with the blade side toward you to get access to the nut to take off blade. As you know the blades go down( clockwise when operating to cut wood) and of course now, you have the problem of taking off the blade counter clockwise because the angle of the blades are going back words, ( nothing to grab on to the wood, to put a wrench on going counter clock wise to take nut off. What the idea for you and normal way is this, as the saw is on the side, with the nut/blade side toward you, you wedge the piece of wood, between the left top side of blade under the frame of the blade, meaning you are wedging it in, so the blade when turning the nut counter clockwise to unscrew, will stay in place. Think of it as wedging the blade with a chunk of wood, so it will not move. AGAIN, it comes off (nut) counter clockwise, so, you are just using this wood chunk to keep blade from moving, and then to put new blade on, just reverse procedure. Thanks Mike

SOURCE: Skilsaw 3310, motor turns on and runs blade does not. Blade changed and tight on shaft

if the blade is mounted correctly and tight and the motor is running, the only other explanation for a failure is a stripped gear in the gear box
