EXTENDED OPERATION/EXTREME CONDITIONS
Vibration and Cold
It is believed that a condition called Raynaud’s Phenomenon, which
affects the fingers of certain individuals may be brought about by
exposure to vibration and cold. Exposure to vibration and cold may
cause tingling and burning sensations followed by loss of color and
numbness in the fingers. The following precautions are strongly
recommended because the minimum exposure which might trigger the
ailment is unknown.
To reduce the risk of RSI/CTS, do the
following:
•
Avoid using your wrist in a bent,
extended or twisted position. Instead try
to maintain a straight wrist position.
Also, when grasping, use your whole
hand, not just the thumb and index finger.
Takeperiodicbreakstominimizerepeti-
tion and rest your hands.
•
•
•
Keep your body warm, especially the head, neck, feet, ankles, hands
and wrists.
Maintain good blood circulation by performing vigorous arm
exercises during frequent work breaks and also by not smoking.
Limit the hours of operation. Try to fill each day with jobs where
operating the blower or other hand-held power equipment is not
required.
If you experience discomfort, redness and swelling of the fingers
followed by whitening and loss of feeling, consult your physician
before further exposing yourself to cold and vibration.
•
•
•
•
Reduce the speed and force in which you
do the repetitive movement.
Do exercises to strengthen the hand and
armmuscles.
Immediately stop using all power
equipment and consult a doctor if you
feel tingling, numbness or pain in the
fingers, hands, wrists or arms. The
sooner RSI/CTS is diagnosed, the more
likely permanent nerve and muscle
damage can be prevented.
•
Repetitive Stress Injuries
It is believed that overusing the muscles and tendons of the fingers,
hands, arms and shoulders may cause soreness, swelling, numbness,
weakness and extreme pain in those areas. Certain repetitive hand
activities may put you at a high risk for developing a Repetitive Stress
Injury(RSI). AnextremeRSIconditionisCarpalTunnelSyndrome
(CTS), which could occur when your wrist swells and squeezes a vital
nerve that runs through the area. Some believe that prolonged exposure
to vibration may contribute to CTS. CTS can cause severe pain for
months or even years.
EQUIPMENT
• Check unit for loose/missing nuts, bolts and screws. Tighten
and/or replace as needed.
• Inspect fuel lines, tank and area around carburetor for fuel leaks. DO
NOT operate unit if leaks are found.
• Do not use blower if any part is missing or damaged.
• Have repairs done only by an authorized ECHO Service dealer.
• Do not use any attachment, accessory or replacement part unless it is
recommended in this Operator's Manual.
• Avoid contact during and immediately after operation. Always keep
exhaust area clear of flammable debris. Allow the engine and muffler
to completely cool before performing any maintenance activity.

PRE-OPERATION
FUEL
Fuel Requirements
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.
IMPORTANT
Spilled fuel is a leading cause of
hydrocarbon emissions. Some states
may require the use of automatic fuel
shut-off containers to reduce fuel
spillage. Contact your ECHO dealer
fororderinginformation.
TwoStrokeOil-Atwo-strokeengineoilmeetingISO-L-EGD(ISO/CD
13738) and J.A.S.O. FC Standards must be used. Echo brand premium
Power Blend TM Universal 2-Stroke Oil meets these standards. Engine
problems due to inadequate lubrication caused by failure to use an
ISO-L-EGDandJ.A.S.O.FCcertifiedoil,suchasEchopremiumPower
Blend TM, will void the two-stroke engine warranty. (Emission related
parts only are covered for two years, regardless of two-stroke oil used,
per the statement listed in the Emission Defect Warranty Explanation.)
AfterRefueling
• Wipe any spilled fuel from the unit.
• Move at least 3 m (10 ft.) from refueling
location before starting the engine.
IMPORTANT
After use
EchopremiumPowerBlendTM Universal2-StrokeOilmaybemixed
at 50:1 ratio for application in all Echo engines sold in the past
regardless of ratio specified in those manuals.
• DO NOT store a unit with fuel in its tank.
Leaks can occur. Return unused fuel to an
approved fuel storage container.
Mixing Instructions
1. Fill an approved fuel container with half of the required amount of
gasoline.
2. Add the proper amount of 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.
Storage - Fuel storage laws vary by locality.
Contact your local government for the laws
affecting your area. As a precaution, store
fuel in an approved, airtight container. Store
in a well-ventilated, unoccupied building,
away from sparks and flames. Do not store
fuel longer than 30 days.
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.

COOLING SYSTEMS CLEANING
Level2.
Tools required: 25 - 50 mm (1 - 2 in.) medium bristle paint brush, Cross
Head Screwdriver, Pointed Wood Stick.
Parts Required: None, if you are careful.
IMPORTANT
To maintain proper engine operating temperatures, cooling air must
pass freely through the cylinder fin area. This flow of air carries
combustion heat away from the engine.
Overheating and engine seizure can occur when:
• Air intakes are blocked, preventing cooling air from reaching the
cylinder.
• Dust and grass build up on the outside of the cylinder. This build up
insulates the engine and prevents the heat from leaving.
Removal of cooling passage blockages or cleaning of cooling fins is
considered “Normal Maintenance”. Any failure attributed to lack of
maintenance is not warranted.
Cleaning Grill
1. Remove accumulated debris from intake grill between backpack
frame and blower housing.
