Question about Skil 7 1/4" Magnesium "Mag 77" Wormdrive Saw With Twist Lock Model # SHD77M 72

Skilsaw motor runs blade won't turn

I purchased an older used Skilsaw (8 1/4") Model 825. I got the saw home and plugged it in to find the blade does not turn when the trigger is pulled. The motor appears to run fine. The blade turns freely by hand, but not at all when the trigger is pulled. When I turn the blade manually it does not appear to turn the motor windings. Also, there appears to be a couple of places when I turn the blade manually where there is a little more resistance / and I can hear a metal on metal type of sound. Any ideas? Any help would be greatly appreciated.

It sounds like you bought a lemon possibly. I am thinking that the gears are bad. What you can do is remove the blade and unplug the saw. locate where the screws holding the bearing cover are and remove them to get to the gear and check it. Let me know if you need more help

How to change blade on skilsaw 5380


on a circular saw
pull the power lead from the plug
using a screw driver , place the blade between the teeth and turn until the screw driver is jammed under the plate
use a ring spanner and undo the nut that holds the blade on
pull the blade out and fit the new blade with the direction arrow in the right direction
replace the plate and the bolt do the bolt up tight
rotation will tighten it up
some blades have a hole in the blade in which to insert the screw driver to hold the blade , or a lock lever behind the cover to hold the armature shaft while changing the blade

Witch way to turn the blade bolt on a 10" table saw


I'd be surprised if it were anything but a normal, right handed thread.

So, put on some leather gloves, block the blade from turning with a piece of scrap lumber. Use the appropriate size blade wrench and, I assume you're removing the blade, pull the wrench toward you to loosen it. Always remember, lefty loosy, righty tighty and you'll never wonder which way to turn it again. Obviously if this method tightens the nut rather than loosening it, it's a left handed thread and needs to go the opposite direction. Should loosen/tighten rather easily, so don't force it one way or the other.

Blade change skilsaw 5150


The locking button on this saw is designed for safety. If you are attempting to change the blade it should NOT be plugged in. It sounds as if someone has pushed the lock button while the motor was running and sheared it off.
The only tool that is required to change the blade is the supplied wrench or an equivalent box end. If you cannot make the repair yourself for have the equipment repaired you can take a pair of vise grips. (Use cardboard to prevent warping or gouging the blade) and clamp the edge of the blade below the teeth. The vise grips will stop at the front of the saw as it is too large to pass by the guard allowing you to loosen the nut. Clamp the new blade in the same way only the back of the saw will be used to tighten.

I highly recommend that you either repair yourself or have the tool repaired by a professional.

Parts schematics are all over the net for this tool, here is an example:

As you can see most of the mechanical parts are only a few dollars and it could save you from serious injury during operation.
