RULES FOR SAFE OPERATION
A. Kickback Safety Precaution for Chain Saw Users
WARNING!
KICKBACK may occur when the nose or tip of the
guide bar touches an object, or when the wood
closes in and pinches the saw chain in the cut.
Tip contact in some cases may cause a lightning
fast reverse REACTION, Kicking the guide bar up
and back towards the operator . Pinching the saw
chain along the top of the guide bar may push the
guide bar rapidly back towards the operator. Either of these reactions may cause you to lose control of the saw which could result in serious personal injury .
Do not rely exclusively upon the safety devices built
into your saw. As a chain saw user , you should take
several steps to keep your cutting jobs free from
accident or injury .
1. With a basic understanding of kickback, you
can reduce or eliminate the element of surprise.
Sudden surprise contributes to accidents.
2. Keep a good firm grip on the saw with both
hands, the right hand on the rear handle, and
the left hand on the front handle, when the engine is running. Use a firm grip with thumbs and
fingers encircling the chain saw handles. A firm
grip will help you reduce kickback and maintain control of the saw . Don’t’ let go.
3. Make sure that the area in which you are cutting is free from obstructions. Do not let the
nose of the guide bar contact a log, branch, or
any other obstruction which could be hit while
you are operating the saw.
4. Cut at high engine speeds.
5. Do not overreach or cut above shoulder height.
6. Follow manufacturer’s sharpening and maintenance instructions for the saw chain.
7. Only use replacement bars and chains specified by the manufacturer or the equivalent.
B. Other Safety Precautions
1. Do not operate a chain saw with one hand! Serious injury to the operator, helpers, byst anders, or any combination of these persons may
result from one-handed operation. A chain saw
is intended for two-handed use.
2. Do not operate a chain saw when you are fatigued.
3. Use safety footwear; snug-fitting clothing; protective gloves; and eye, hearing and head protection devices.
4. Use caution when handling fuel. Move the chain
saw at least 10 feet (3 m) from the fueling point
before starting the engine.
5. Do not allow other persons to be near the chain
saw when starting or cutting with the chain saw .
Keep bystanders and animals out of the work
area.
6. Do not start cutting until you have a clear work
area, secure footing, and a planned retreat path
from the falling tree.
2
7. Keep all parts of your body away from the saw
chain when the engine is running.
14.Keep the handles dry , clean, and free of oil or
fuel mixture.
8. Before you start the engine, make sure that
the saw chain is not contacting anything.
9. Carry the chain saw with the engine stopped,
the guide bar and saw chain to the rear , and
the muffler away from your body .
10.Do not operate a chain saw that is damaged,
improperly adjusted, or not completely and
securely assembled. Be sure that the saw
chain stops moving when the throttle control
trigger is released.
11.Shut off the engine before setting the chain saw
down.
12.Use extreme caution when cutting small size
brush and saplings because slender material
may catch the saw chain and be whipped toward you or pull you off balance.
13.When cutting a limb that is under tension, be
alert for spring back so that you will not be
struck when the tension in the wood fibers is
released.
15.Operate the chain saw only in well-ventilated
areas.
16.Do not operate a chain saw in a tree unless
you have been specifically trained to do so.
17.All chain saw service, other than the items listed
in the Instruction Manual maintenance instructions, should be performed by competent chain
saw service personnel. (For example, if improper tools are used to remove the flywheel
or if an improper tool is used to hold the flywheel in order to remove the clutch, structural
damage to the flywheel could occur and could
subsequently cause the flywheel to burst.)
18.When transporting your chain saw, use the
appropriate guide bar scabbard.
19.Spark arrester mufflers approved to SAE Standard J335b are Standard on ECHO Chain
saws to reduce the possibility of forest fires.
Do not operate the chain saw with a loose or
defective muffler . Do not remove the spark arrester screen.

FUEL STATEMENT
Gasoline - Use 89 Octane [R+M/2] (mid grade or higher)
gasoline known to be good quality. Gasoline may contain up to
15% MTBE (methyl tertiary-butyl ether). Gasohol containing
methyl (wood) alcohol is NOT approved.
Oil
Two Stroke Oil - A two-stroke engine oil meeting ISO-L-EGD
(ISO/CD 13738) and J.A.S.O.
Echo brand Premium 50:1 oil meets these standards. Engine
problems due to inadequate lubrication caused by failure to use
an ISO-L-EGD and J.A.S.O.
Premium 50:1 Two-stroke Oil, will void the two-stroke engine
warranty. (Emission related parts
years, regardless of two-stroke oil used, per the statement
listed in the EPA Phase I Emission Defect Warranty Explanation.)
IMPORTANT
Echo Premium 2-Stroke Oil may be mixed at 50:1 ratio
for application in all Echo engines sold in the past regardless of ratio specified in those manuals.
Mixing Instructions
1. Fill an approved fuel container with half of the required
amount of gasoline.
2. Add 2-stroke oil to gasoline.
3. Close container and shake to mix oil with gasoline.
4. Add remaining gasoline and remix.
5. Install fuel container cap and wipe any spilled fuel from
container and surrounding area.
IMPORTANT
Stored fuel ages. Do not mix more fuel than you expect to
use in thirty (30) days, ninety (90) days when a fuel stabilizer is added.
FC Standards, must be used.
FC certified oil, such as Echo
only are covered for two

Gasoline
Fuel Mix Chart
50:1
Stored two-stroke fuel may sep arate. ALWAYS shake fuel
container thoroughly before each use.
IMPORTANT
Spilled fuel is a leading cause of hydrocarbon emissions.
Some states may require the use of automatic fuel shutoff containers to reduce fuel spillage. Contact your ECHO
dealer for ordering information.
CHAIN LUBRICANT
Proper lubrication of the chain while in operation reduces friction
between the chain and the guide bar to a minimum and assures
a longer service life.
• Use high quality ECHO bar and chain oil for this purpose.
• Do not use used or reclaimed oil to avoid various oiler
problems.
• Use bar and chain oil of the following grades:
SAE NO. 30 ..... in summer
SAE NO. 10 ..... in winter or when cutting resinous trees.
• When refueling, also refill chain oil.
