Crap! I did it again. My HP 18" gave me an oil shower this morning. It uses a toggle switch to shut off when the chain pulls tight. The problem is that it doesn't completely click to off so when I open it up and pull the saw vice back it starts running and showering me and everything else in the vicinity with oil. I have to remember to click the switch all the way off before opening the saw. I replaced the toggle switch but that didn't solve the problem. I'm thinking of ordering a paddle on/off switch that I see in the Grizzly catalog. It looks like I can adapt it to the current way the saw is set up now. grizzly.com/products/110-220V-Paddle-On-Off-Switch/H8243Anyone else have a suggestion on a good, reliable switch setup? I'm getting tired of these impromptu oil showers... Rick

Have it pull a spring loaded pin, or what ever you can rig up. Kind of like springing a snare or something. Like a mouse trap, either it is set, or gone off, no half way. This way, once triggered, it will completly switch off.

I have a lortone 10" saw that does the same thing, but I have never had any problems with my HP 18", it shuts off good. Which kind of switch is on yours? I do have a spare switch for the HP, just wondering what kind of switch is on yours.

Utah, I like your idea. I have a selection of springs I bought at Harbor Freight. Maybe I can rig up a helper spring that will give the switch that extra boost to click fully off. Tony, I have the same problem with my Lortone 10" but I usually don't get sprayed because I tend to switch it completely off when I reach in to move the saw vice and getting my big hand between the lever and stop chain clicks the switch completely off. I have included some photos of what my switch set up is. I don't know if it is original Highland Park setup or a do-it-yourself addition... Rogue, Good idea on the magnetic kill switch. I've seen those on new saws... OK, here is a shot on the switch as it is when the saw shuts off by tension on the chain. As soon as I release the tension by moving the saw vice back the saw starts up and I get a shower. Here is the switch in the full off position. And here is a shot of the switch and shut off chain.

Rick,I've taken a few oil showers too.The worst one was during the last Super Bowl,I had the volume on the TV way up and I was slabbing during the game.I had the saw going along with three rotary tumblers and two vibes.The saw is quiet due to its half inch thick PVC tank and lid.After a play I went to check the saw and with all the racket I didnt notice it was still running and opened the lid,I was holding my very white dog at the moment and we both got drenched with bright red oil.We both looked like we got chainsawed.I decided right then it was time to idiot proof the saw.I used a little Microswitch with a bolt on the lid.The switch is wired normally open so when the lid is closed it allows power to the motor.If the lid is open it wont turn on.My on/off switch is on the front of the saw where I like it and a couple of times when I was working on the saw I accidently hit the switch and got a bath.this setup cured it and took a minimal amount of time and money to install.Well worth the effort.

My old HP I had did the same thing and I finally just turned it off manually every time. Top it off, the switch was right were I ran into it with my leg when I reached into the carriage so sometimes I switched in on with my leg! You're right too, man it really gives you a nasty bath, especially if the oil ain't been changed in awhile *L*....Mel

Yeah, I've seen those old pushbutton switches and they do work. I'm trying to locate one on Granger.com but I can't come up with the right search...

My 24/18 also has the old style push button. I tried looking on Mcmaster and can't seem to find it. I've never taken it apart to see how it works but it always works. If it is like mine, the chain pulls the red/stop button into place, and the green/go button is recessed into a shroud so that I can't bump it on while placing the rock. Looks sort of like this: from MSC Direct but I'm sure what I have didn't cost $250!

Dean,
That's pretty much the prices I'm finding in the Grainger catalog. A little to rich for my blood...

I must be using bad search terms. I've spent a while looking and can't find another one like what is on my saw.
I have seen other people use a regular light switch, mounted side-ways, with a hole through the lever. The chain-hook attaches to the lever-hole. Could be a more positive disconnect that way.
