Practice your transitions from down cut to up cut and back down.
A lot of times a really fast saw gets smoked because the operator tries to transition too fast.
Also try to let the saw do the cutting, if you push you run the risk of bogging the saw.
If you run a 16" bar take your dawgs off.
If you run a 16"-20" bar you can probably get away with a 9 tooth sprocket,
As long as your not cutting hardwood or anything over 10" diameter.
Above all else have fun with it and don't be too competitive, if the others like the way you
operate they will offer advice.
Remember there is always something new to learn, so have patience and have fun!
