• 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 chain saw 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 handlebar 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.
Note: Some material may adversely affect the housings of your
ECHO chain saw.(Example: Palm Tree Acid, fertilizer,
etc.) To avoid housing deterioration, carefully remove all
packed saw dust around clutch and guide bar area and
wash with water. Coat metal parts with light oil.
Felling The Tree
A falling tree can seriously damage anything it may hit - a
car, a house, a fence, a power line, or another tree. There
are ways to make a tree fall where you want it, so first
decide where that is!
Before cutting, clear the area around the tree. You will need
good footing while working and you should be able to work the
saw without hitting any obstacles. Next, select a path of retreat.
When the tree begins to fall you should retreat away from the
direction of fall at a 45-degree angle and at least 3 m (10 feet)
from the trunk to avoid the trunk kicking back over the stump.
