Friend took kickback to the face. **WARNING** Pictures not for the faint

[Dave D]

wish him a speedy recovery. all things considered hes probably had a very lucky escape.

lucky to get away with limited injury - bet his he was in shock, problem his saw would still be running after the accident.

 

I always assumed a kickback was the saw lifting up when in both hands with too much power to hold the saw, relying on the brake, so I work with my left hand tipped forward to ensure the brake will apply quickly but I had a minor incident a while ago when the end of a 20" bar 'touched' when unexpected and the saw lifted pulling my right hand off the saw. The saw pivoted on my left hand flicking up, I was totally taken by suprise and didn't have time to tip my left hand forward OK nothing happened but it was abit of a shock, I only mention it if helps stop the unexpected.

The chain brake should come on automatically due too inertia in a kick back situation, the chain brake handle is there so you can apply the brake, take the brake off and it acts as a hand guard.

If you take a look at my thread reply about my table saw kickback it will give you an idea about how a spinning blade at 1200rpm, I believe that when these things happen your body, mental state and reactions go into overdrive, meaning you will do things very quickly to preserve yourself.

 

People have died from the injury in this thread, and from table saws.

 

I will say that this was a very lucky getaway!

 

:confused1:How do you get kickback from a table saw???????

 

Its fastened to a table and you present the timber to the saw, not the saw to the timber??

 

I know you can get timber throw at you if its not presented correctly, but that not really kickback.

Tree work a bit slow

 

Hi Tom, Only do trees at weekends on an estate. Medical engineering in the week, I have seen alot of recontructed skulls from gunshot wounds. The front of the skull is full of small bone and tissue, so is quite weak.

 

The photos got me thinking, I assumed a kickback with no brake cutting in would give a very deep wound but the two pictures shown are shallow?

 

For a large saw to kick back, it would be one of three situations;

 

1, saw kicked up with brake coming on = face contact with static chain giving small cuts and brusing.

 

2, saw kicking up with right hand pulled off saw, no brake applied = a freewheeling chain to contact the face giving shallow say 25mm rough wound.

 

3, saw kicking up throttle open, no brake = a chain contacting face under full power = say in contact with face for 1 second, I would expect a very deep wound say 50mm or more, possibly fatal.

 

my dog killed a pheasant this morning while 'helping' the gamekeeper, so may give it a go and test it with a freewheeling chain as the bone/tissue is simular.

 

will let you all know what happens when I get home - better not do it in the hospital carpark:sneaky2:

As I stated in my earlier post, if you need to apply the chain brake in a kickback your saw needs fixing!!! it should come on automatically!!!

To follow on from my last post.

 

I tested out a saw on over-run only and it practically cut the pheasant in half. I assumed a free running chain would have less kinetic energy. From this I assume the injuries shown could have been the result of a saw kicking back with the right hand being pulled free and the brake not coming on.

 

Like most I assumed a kickback was the result of a saw lifting under power and being saved by the brake. From what I have found I now wonder how much research & testing on PPE has been done on 'kickbacks'. It's only too easy to blame it on 'pilot error' - when the pilot gets all the blame letting off the owners/makers etc off the hook, or in the case of a kickback to blame the person for not 'doing it right'. From what I found it's easy for a saw to be pulled from the right hand.
