SOURCE: To get the blade guard on a Ryobi circular saw to stay up.

Hello. The blade guard is specifically designed to not stay up but instead to only come up as the wood pushes it up. This is a problem when you are trying to do a plunge cut but it is a safety feature. Joe

How do i get to the trigger on a dwalt939 circular saw

The way your saw is built, the only way to get the switch is to split the clamshell. Depending on where the screws holding the two halves together are, you may or may not have to remove the upper blade guard and shoe assembly to do it.

How do I replace the blade guard on a Dewalt DC390K saw

Remove the clip behind the back blade flange holding it on to the housing and lift it up of the return spring, replace the opposite way remembering to relocate the return spring. Make sure you get the model number correct as the 390 and 390k are different.

I don't have this particular model in my shop right now but almost all circular saws work like this. From the blade side of the saw, the spring attaches to a hole in the blade guard usually around the two to three o'clock position. With the blade guard correctly positioned on the saw, wrap the spring clockwise around the bottom of the hub and back up the nine o'clock side. There is another hole or tab inside the top of the upper blade guard somewhere around the twelve to two o'clock position. Hook the end of the spring there and test the guard for free movement throughout it's range of motion.

I have dewalt 18 v circular saw i cut vinyl lattice once and used it on a 2x4 but it wouldnt cut it, started to cut then just stopped. is blade dull already? new saw.

a couple things to look at. Did the saw stop operating or was the blade not wanting to cut. Remove the battery and CAREFULLY feel the blade for dull or broken segments. If the blalde stopped check to make sure not a loose bolt holding it on. Did you reverse the blade for cutting the vinyl. Let me know more information and I will try and help

Ryobi TS-254 blade guard does not retract when blade is lowered

Probably something jammed up inside the body of the saw where the guard retracts, like a chip of wood. I once had the same problem with my circular saw guard not retracting. Turned out there was a screw that had somehow gotten trapped in there and once that was removed, guard functions perfectly now. Definitely sort it out as soon as possible because this is very dangerous--you could make a cut, rest the saw on your leg and... earn a quick trip to the emergency room.

I have a Porter Circular Saw, 18v, Cordless, 6 and a half inch blade. I'm a novice, so I unhooked the wire latchet that held the lower guard on. I figured out how to put the saw blade on, yet I have the...

Remove the battery, take the blade back off and you will see the holes for the torsion spring. what you will have to do is start putting lower guard on but pretenstion the spring so it will fit back into the proper holes, it might be a benefit to remove the small bumper so that you can move the guard more. when installing the blade you don't remove the lower guard just retract it and slide the blade in place. Usually there is a retaining ring to hold the guard in place but I looked at a breakdown and didn't see one. Let me know if you need more assistance before voting please. Thank you

How do I remove 12" blade from from dw705 miter

loosen the guard screw, UNPLUG tool first, move the guard out of the way, there is a spindle lockon the backside of the gearcase push it and slowly turn the blade until it engages and then remove the bolt, it is a left hand thread. DO NOT disassemble the guard, just loosen bolt and move out away from blade also you need to have the head in the raised position.

How do i change the circular saw blade on my saw? because i cant get the blade out to swap it as its blunt and the blade is now blunt

After removing the blade bolt and the outer flange you will need to fully retract the lower guard (remove battery) and sometimes wiggle the blade but it will come out.
