Ok…I give up. After 8 years I need to change the blade on my Dewalt 715 miter saw. I can’t find the manual (I think it’s in the unheated shop about 150’ from here requiring a trip across what looks like a hockey rink, and I don’t skate) and the internet only wants to sell me a new one.

I have the factory wrench and I understand the arbor lock. Is it lefty loosey/righty tighty or reverse thread? It’s been through a lot without change so the fact that a reasonable tug either way didn’t work was expected but I didn’t want to make it worse by going the wrong way.

and btw…I asked my hardware guy today about sharpening…they send them out and the going rate is 50 cents/tooth. 80 teeth = $40. new blade $49…made it pretty easy. I’ll keep the old one for rough work.

when im not sure which way it threads i use my thumb nail on the thread and turn the shaft to see which way it pulls my thumb . simple but effective.

got it. it is left threaded. for the benefit of others, unplug the saw, lift the blade guard and you’ll find a big torx screw on the left side of the blade that secures the guard. loosen enough to disengage and swing the blade guard (only about an inch or so) to get better access to the blade bolt. skip the factory wrench in favor of a 1/2” socket and turn clockwise while holding the arbor lock to loosen the bolt. you might find that a friend will come in handy to hold things since your two hands are already spoken for.

the factory issue apparently has a 1” arbor adaptor installed so if you have a 5/8” arbor blade (rare I think in the 12” blades), that comes off. old blade off, new blade on, then reverse the steps.

Have your say...
