Primarily: They don't want you to know the angle of the cutting edge to be sharpened.

My Ozito Chainsaw's Instruction Manual says nothing about the angle.

The Googled info of my chainsaw says nothing about what the angle is.

There is no embossed marking on my chainsaw chain to let me know what the angle is.

On the packet of a chainsaw chain I bought a while back there is no info about the angle the cutting edge must be sharpened at.

Other searches on Google just vaguely give the information that the angle is anything from 10 degs to 36 degs.

Unbelievable.

In fact it's criminal.

I'm thinking of blacking-up and going on a rampage of looting through my local shopping strip.

The angle of chain sharpening depends on if its to be used for cross cut or rip sawing, and the type of timber to be cut.

It's a manual, 45 degree "go by eye" operation - and a few degrees either way matters neither here nor there

That said - the GREATEST of chain sharpeners will let you know your chain 'has a life of FOUR to FIVE sharpenings, at BEST

The TRICK is ...

DON'T HIT THE DIRT

ALL said and done - you can NEVER sharpen a chain up to "as new"

... and being a lazy bastard, I fork out the thirty odd bucks ' and shout myself a NEW ONE, every couple of months

Thanks all! Good advice.

But!

I've learnt a couple of things since.

If you want your chainsaw to cut slowly while maintaining the sharpness of the teeth edges longer, then set the angle to 25deg.

For fast cutting but at the cost of needing to sharpen the teeth edges more often ~ set the angle to 35degs.

This latter is what I did ~ and it worked like a beaudy, and didn't blunt the teeth. That was a fallen tree trunk 35cm in diameter.

Yes, Buzz ~ it's the soil dust on these pieces of timber that act like emery paper filing down the cutting edges.

That's why I used my water-blaster m'c to hose off as much dust as possible before doing the chainsawing.

All good.

I also fixed my disc brake assembly as never before. Took it apart and finally understood how it works. I wonder if that's asbestos padding there.
