If you are using a "circular" type saw, be sure the GUARD DROPS BACK DOWN after the cut.
Many of us use one to fabricate wood parts for cabinets.
I saw one where the saw took off over the hard wood floor, leaving a nice trail behind that.
The carpenter never repaired it either. This was at my parents house.
I came home to find the contractor's crew was working on my home and there was a huge pile of blue jeans shredded in the driveway. I asked what happened, fearing a leg amputation of such, but saw no blood, & one of the guys sheepishly said he was cutting a board with a circular saw and got the blade tangled in his pants leg.
(Talk about a major brown pants moment.)
Thankfully, he was not injured, but is sure scared him & the rest of the crew.
The other time actually happened to me. I had been cutting a lot of material for a project & I put the saw down before the blade had spooled down. The guard stuck and the saw headed off down the drive way.
( Man, a Skill 77 can really scoot!
)
So now I am very careful to be sure the guard is down or let the saw spool down before setting it down.
I was lucky someone was not near me as it could have easily removed a body part in it's travels.
After talking to a few carpenter friends, I found out that this is not an uncommon event!!!
The guard can get gunked up with sawdust & dirt, or the saw dropped or something landing on it to bend the guard. I had dropped mine on it's side from 8 ft up framing a shed in
A quick disassembly job, cleaning and a bit of metal reforming & it didn't happen again. Believe me, I literally tested it 25 times to be sure the guard wouldn't stick again.
