Quote HistoryQuoted: Psi set too high? Yeah that's what I'm thinking. Hydraulics overheated shortly after and truck almost caught on fire. Pretty neat.  |

Not holding the blade square and steady in the cut?
Always rest part of the guard on the object and pivot the blade into the cut. Especially important if the cut is very deep or long. |

Chop saw blades scare the shit outta me.
One of my buddies constantly sideloads his to clean the shavings off his workpiece. Makes me nervous every time he does it. |

Looks like your saw has some hatred for your right foot too.
 Be safe out there and remember safety third. |

I bought one of these 6 years ago and couldn't be happier. I've only changed the blade twice and I use it a lot.

check the RPM rating of the blade vs the saw I wonder if he put the blade in a miter saw ( designed for cutting wood ) ???? Even so they have blades rated for those ..... because I use a miter say and a abrasive blade with no issues. |

I've had all kinds of grinding stones and cutting blades blow up on me over the years. Not fun at all.

Had a diamond blade blow up on me once while cutting 60" elliptical concrete pipe with one of those Stihl chopsaws. That was pretty interesting. Had to dig shrapnel out of my stomach area and side.
We went back and looked at our other blades and noticed they were all fatigued in the notch area of the teeth. That, combined with cutting an angle in to the pipe to negotiate a curve under an intersection, caused the kaboom. I got lucky as the only PPE I had on was leather gloves, steel toe boots and safety glasses. ETA: Now that I think about it, I remember watching the blade "flexing" while I was cutting. Like a wave in the blade as it was spinning. In the back of my head thinking "Hmmmm...." |

Back in the day, we (fire dept) would not store rescue blades with fuel. Someone in the know suggested that fuel may breakdown the composite material used in the blades causing failures like you had. Not saying that's the cause but you never know.

Scary stuff--at least you didn't get hurt, and are now, without a doubt, a believer in PPE. That's a good day by any standard.

Did it chop your dick off?
...sorry, I couldn't resist. A big part of my work is investigating work related accidents for major insurance companies. Grinder operators are often leaning too hard on the grinders or overclocking them...and the explosion usually happens at about crotch level 
Sorry, wifey...work comp does NOT pay for "Loss of Consortium" in most states. |

Not saying that's the cause but you never know. The above is actually something I have gone by for years and still a practiced standard in the fire service. Our mix and regular fuel is always located in another separate compartment. Have cut some crazy stuff through the years but daily operational checks, matching saw blade to the saw, for intended purpose and keeping saw in good shape are of primary importance. |

Quote HistoryQuoted: Scary stuff--at least you didn't get hurt, and are now, without a doubt, a believer in PPE. That's a good day by any standard. I was wearing all my PPE (face shield, goggles, welding jacket, leather leggings) and the guard on the saw deflected everything away from me. Good story to remind people about safety, especially people who walk in front of the saw. Quoted: metal or masonry? Carbon steel. Quoted: I wonder if he put the blade in a miter saw ( designed for cutting wood ) ???? Even so they have blades rated for those ..... because I use a miter say and a abrasive blade with no issues. Saw and blade are specifically designed to go together and for the purpose I was using them for. |
