Dull chains...does it really kill saws....how?

[dustinwilt68]

I don't care what engine it is, heat is the always the enemy, and a dull chain puts a longer load on the engine creating more heat, add in the additional load of the operator pushing the saw to try and make it cut, operator error has to the number 1 factor in killing good saws, ie. Bad fuel mix, dull chains, poor maintenance.

I had an old farmer once tell me ,son a sharp tool will always make you money ,a dull one will cost you .

Holding one wfo tuning it makes my hair stand up.
I don't do it but just a second.
I see guys hold one wfo forever,no load rpm is bad for things.

Am I that guy? Lol

It scares me a bit too, but I hold me for 2-3 seconds at WFO to get high tune. That's after a few blips to make sure nothing comes apart. Never without a bar and chain on a saw, so there is some slight load.

Good question Mattyo. I've wondered the same about what part actually does hurt the saw. I don't run dull chains because it's a waste of time.

A blunt chain doesn't load the saw up and drop revs like a sharp one.
Imagine piss reeving your saw for 3 tanks of fuel.

I got an 034 super from a bloke who also gave me about 15 chains that were about 1/4 used and had been run in dirt.
I will have to get a picture of the cutters. Its horriffic.
The bar was a solid GB pro bar and he had been pushing on those chains with rounded off cutting edged so hard trying to get them to cut, he had flared the bar rails out at 30* angles.

The entire saw was cooked.
It looked like it had been put in an oven and roasted till crispy.
Every rubber part was brittle.
All the saw dust and oil under the plastic cover around the clutch had been on fire at one point.

I will agree with blunt chains being the No.1 saw killer.

Ok....completely serious question...as raised on my youtube channel.

How does a dull chain kill a saw?

Doesn't it put less load on the engine? Sure it revs high for long without doing any work...but what is the actual mechanism of failure....

This makes me feel more retarded.

Friction. Pure and simple. Dull cutters don't cut, they RUB. That causes friction which builds heat on the chain. Lean on the saw and you're adding more friction. The chain carries the heat to the crank and so on.

I bought a nice 066 from a bloke who sold it cheap cause it didnt cut any good
I saved his chain to try one day

 

[peter92]

Now this brings in another point of getting hot
Those that just use engine oil as bar oil
Whats your thoughts on this

When I was in boy scouts they alway said you get cut with a dull knife not a sharp one .

[peter92]

Did you watch the video?

Part of it , ill watch it all

 

[Brewz]

Tomorrow I will fit one of the dirt dulled chains to an 036 and try it.
Will get a video.

 

[peter92]

Did you watch the video?

yes i did , but what do you think of it

 

[Moparmyway]

Did you watch the video?

WOW !!
Muh dull ones cut better than that sharpened one

Also read the comments,

Stupid idea if you ask me

I once had a local bring me a saw asking me to fix it cause it would not cut.
It was a nice little Husky 136 that was his dads saw.
He had paid to have it sharpened 3 time at $30 a hit and it still wouldn't cut

The morons in the shop were not taking down the rakers.
I filed the rakers and he was over the moon. Gave it a muffler mod for free too..... couldn't help myself.
Also told him I could get him a new chain for half the price he was paying to sharpen the chain.

He bought files and I have been teaching him how to use them
