•ReadtheECHO“CHAINSAWSAFETYMANUAL”
included with your chain saw for additional
cutting and safety instructions.
•Wearsuitablehearingprotectionsuchas
earmuffs or earplugs to protect against
objectionable or uncomfortable loud noises.
•Donotletthetipofthebartouchanythingwhile
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 difcult 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 nger.
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 cut-
ting 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 cut-
ting will actually be more difcult.
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.
