Do not let the tip of the
bar touch anything while
the engine is running. At
cutting speed the chain is
moving at a high rate of
speed. Should the tip
contact a limb or log while
the chain is moving, the
tip will be pushed upward
with considerable force.
This is known as kickback. Avoid it!
In all circumstances the operation of the chainsaw is a one-man job. It is
difficult at times to take care for your own safety, so don’t assume the
responsibility for a helper as well. After you have learned the basic
techniques of using the saw, your best aid will be your own good common
sense.
The accepted way to hold the saw is
to stand to the left of the saw with
your left hand on the front handle
and your right hand on the rear
handle so you can operate the
throttle trigger with your right index
finger. Before attempting to fell a
tree, cut some small logs or limbs.
Become thoroughly familiar with the
controls and the responses of the
saw.
Start the engine, see that it is
running properly. Squeeze the
trigger to open the throttle wide
open and start the cut. If the chain is
properly sharpened, the cutting
should be relatively effortless. It is
not necessary to press down hard to
make the saw cut. Pushing the saw
too hard will slow the engine and
cutting will actually be more difficult.
