It hasn't been used much, so I presume I "must" have gotten it into the
dirt, but I don't recall doing that.
Is it possible it came dull?

I realize there is no accurate answer to this, but how many cuts through 12"
fresh pine should it be able to do before it needs to be sharpened, if dirt
is avoided?
1? 10? 100? 1000?


You should be cutting for half a day or a day before you are worrying
about sharpening anything.

Just a few questions. First, forget the diagram. Go get and saw and
look at it. The teeth have two elements: a rake and a cutting
surface. The chain spins from the top to the tip to the bottom. The
chain cuts on the bottom and pulls the saw towards you.

On the top of the bar, when you look at the teeth, there should be a
rake in the front of the tooth, a small gap then the sharpened
surface. The sharpened surface should be pointing forward, on the top
of the chain.

On the bottom of the bar, the teeth should form a slight sag and be
slightly away from the chain, but the guides should still be inside
the bar.

Got get the chainsaw and push the safety shield all of the way away
from you. Now pull it all of the way back towards you. Next, go
start the chainsaw and open it up full throttle. It should make a
heck of a noise and sound like a chainsaw. The blade should be
spinning WAY beyond what you can see and their shouldn't be any
apparent drag on the motor -- it shouldn't sound like it's working.

Also, when you gas it up, do you add oil to the chain's reservoir?
How much oil gets used when you burn a tank of gas?

Try this, look at the saw, and get back to us and someone will be able
to help.


50 or so then sharpen with a chain saw file and do another 50.
