Was bucking some larger dead ash with the 460 this afternoon. Inside of one tree was punky and very powdery. Kicked out powder dust mixed with normal sawdust as i was bucking. I noticed some sparks while cutting and thought i hit a nail but saw kept cutting well. Looked at the muffler and the powder was caked up and sparking. Shut it off and finished with the 261. Ive heard stories of this but first time that im aware of it ever happened to me. Muffler has a slight build up of char now. Its been very dry here. The wood i cut probably could go straight to the stove. We got very little rain from the tropical storm here. Camera died this past week and cell phone takes crappy pics, but it did happen.
There's no catalyst in the muffler of a 460, otherwise it probably would've lit up. I've never seen it happen, but then again I try not to run the saw in the summer heat. As much as I can...
I’ve noticed this on my 362 as well. Burn marks on the wood during long bucking and noodling sessions.
Not uncommon with the type of muff mod I prefer. This lets the hot gases exit quickest. I'm not one to typically "dog in" and let that start a hot spot. And my Husky's cut like a light saber, which helps, lol!
I’ve seen that on my 372 a handful of times. And yeah it’s dry right now. some years back when I was shooting competitively I was testing some loads on my 200 yard range in dry weather like this. A big ol pine stump served as the backstop. Towards the end of the session I’m looking through the glass and see smoke coming from the stump. Just thin copper and lead at 4000 FPS can set wood and wood dust on fire when it finds an old bolt buried in there LOL It was actually difficult to put out it was so dry and no water around. Scared me a bit. Whole dang forest would have gone up.
Not the same but I was noodling some big 40” pine rounds to help some people out. Using a 590 Echo, they have really big holes in the recoil for air. Got to the bottom of the third cut and notice smoke. Tried blowing it out, no luck. Quick trot to the truck and get tools and tear the top cover off. Sucked in a bunch of chips that were glowing red/burning. Melted the wiring clips for the coil wires, melted the coil bracket, warped a section of the top cover and just started melting the coil wire insulation. No more noodling with a 590.
Saws have been known to start fires so in dry conditions a Five gallon back pack fire water pump (pizz Can) - the orange thing in the middle of the picture - is part of my wood cutting equipment!
Me neither. Ive often wondered how a light saber gets sharpened when it gets dull?...fresh batteries?
Since I only process firewood recreationally, I can afford to jump around to do other tasks while cutting. If I am cutting big rounds that requires me use the dogs for leverage I'll make 4-5 cuts and then use another saw to process tops or start moving the rounds toward the truck/trailer. I also keep the saw about 4" from the wood when noodling. My 372 clears chips better that way. That was a suggestion from someone on this forum. That said, I might NEED to buy big bad dogs. For safety sake of course.
I only went about an inch longer and found that I had to cut the bottom spike back. I like using the dogs on larger saws because that puts a lot less tension on the vibro mounts.
The only time I have had a problem was when I hit some metal and through sparks that started a fire in a pile of noodles. I was able to get it out right away.
