Physical Condition

Your judgment and physical dexterity may not be good:

• if you are tired or sick,

• if you are taking medication,

• if you have taken alcohol or drugs.

Operate unit only if you are physically and mentally well.

Eye Protection

Wear eye protection that meets ANSI Z87.1 or CE requirements whenever you operate the unit.

Hand Protection

Wear no-slip, heavy-duty work gloves to improve your grip on the blower handle. Gloves also reduce the transmission
of machine vibration to your hands.

Breathing Protection

Wear a facemask to protect against dust.

Hearing Protection

ECHO recommends wearing hearing protection whenever unit is used.

Proper Clothing

Wear snug fitting, durable clothing;

• Pants should have long legs, shirts with long sleeves.

• DO NOT WEAR SHORTS,

• DO NOT WEAR TIES, SCARVES, and JEWELRY.

Wear sturdy work shoes with nonskid soles:

• DO NOT WEAR OPEN TOED SHOES,

• DO NOT OPERATE UNIT BAREFOOTED.

Keep long hair away from engine and blower intake. Retain hair with cap or net.

Hot Humid Weather

Heavy protective clothing can increase operator fatigue, which may lead to heat stroke. Schedule heavy work for early
morning or late afternoon hours when temperatures are cooler.

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.

• 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 unit 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.

POWER BLOWER

OPERATOR'S MANUAL

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). An extreme RSI condition is Carpal Tunnel Syndrome (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.

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.

• Take periodic breaks to minimize repetition and rest your hands.

• Reduce the speed and force with which you do the repetitive
movement.

• Do exercises to strengthen the hand and arm muscles.

• 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.

DANGER

Do not operate this product indoors or in inadequately ventilated
areas. Engine exhaust contains poisonous emissions and can
cause serious injury or death.

Read the Manuals

• Provide all users of this equipment with the Operator’s Manual
and Safety Manual for instructions on Safe Operation.

Clear the Work Area

• Spectators and fellow workers must be warned, and children and
animals prevented from coming nearer than 15 m (50 ft.) while the
unit is in use.

• Take wind conditions into account: avoid open doors and
windows.

• Do not point blower at people or animals.

Keep a Firm Grip

• Hold the front and rear handles with both hands, with thumbs
and fingers encircling the handles.

Keep a Solid Stance

• Maintain footing and balance at all times. Do not stand on
slippery, uneven or unstable surfaces. Do not work in odd
positions or on ladders. Do not over reach.

Avoid Hot Surfaces

• Keep exhaust area clear of flammable debris. Avoid contact
during and immediately after operation.

OPERATION

WARNING

Moving parts can amputate fingers or cause severe injuries. Keep hands, clothing and loose objects away from all
openings. Always stop engine, disconnect spark plug, and make sure all moving parts have come to a complete
stop before removing obstructions, clearing debris, or servicing unit.

NOTICE: Use of unmixed, improperly mixed, or fuel older than 90 days, (stale fuel), may cause hard starting, poor
performance, or severe engine damage and void the product warranty. Read and follow instructions in the Storage
section of this manual.

FUEL

W ARNING

Alternative fuels, such as E-20 (20% ethanol), E-85 (85% ethanol) or any fuels not meeting ECHO requirements are
NOT approved for use in ECHO 2-stroke gasoline engines. Use of alternative fuels may cause performance problems,
loss of power, overheating, fuel vapor lock, and unintended machine operation, including, but not limited to, improper
clutch engagement. Alternative fuels may also cause premature deterioration of fuel lines, gaskets, carburetors and
other engine components.

Fuel Requirements

Gasoline - Use 89 Octane [R+M/2] (mid grade or higher) gasoline known to be good quality. Gasoline may contain up to
10% Ethanol (grain alcohol) or 15% MTBE (methyl tertiary-butyl ether). Gasoline containing methanol (wood alcohol) is

NOT approved.

Two Stroke Oil - A two-stroke engine oil meeting ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FC/FD Standards must be

used. Echo brand premium Power Blend XTM Universal 2-Stroke Oil meets these standards. Engine problems due to
inadequate lubrication caused by failure to use an ISO-L-EGD (ISO/CD 13738) and J.A.S.O. FC/FD certified oil, such as
Echo premium Power Blend XTM, 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.)

IMPORTANT

Echo premium Power Blend XTM Universal 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.

After use

• DO NOT store a unit with fuel in its tank. Leaks can occur. Return
unused fuel to an approved fuel storage container.

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.

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.

IMPORTANT

Stored two-stroke fuel may separate. ALWAYS shake fuel
container thoroughly before each use.

4 . Tighten spark plug to 150-170 kg/cm (130-150 in. lb.).

COOLING SYSTEM

Level 2.

Tools required: 25 - 50 mm (1 - 2 in.) medium bristle paint brush, Cross

Head Screwdriver

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.

22

Cleaning Cylinder Fins

1 . Disconnect spark plug lead from spark plug.

2 . Remove engine cover (five screws), pull cover away from engine.
3 . Clean cylinder fins (A) to allow cooling air to pass freely.

4. Replace cover and tighten screws.
5 . Connect spark plug lead.

EXHAUST SYSTEM

Spark Arrestor Screen

Level 2.

Tools required: Cross Head Screwdriver

Parts Required: Spark arrestor screen, Gasket

IMPORTANT

Carbon deposits in muffler will cause a drop in engine output and
overheating. Spark arrestor screen must be checked periodically.

A

1 . Remove spark plug and engine cover (five screws).

2 . Remove spark arrestor cover (A), gasket (B) and spark arrestor

screen (C) from muffler. Replace screen if plugged with carbon
deposits.

NOTE

When cleaning carbon deposits, be careful not to damage the
catalytic element inside muffler.

3. Install spark arrestor screen, gaskets, and cover.

4. Install spark plug and engine cover.

Cylinder Exhaust Port

Level 3.

IMPORTANT

The cylinder exhaust port must be inspected and cleaned of excess
carbon every 3 months or 90 hours of operation in order to maintain
this engine within the emissions durability period. ECHO strongly
recommends that you return your unit to your ECHO dealer for this

important maintenance service.

CARBURETOR

ADJUSTMENT

Engine Break-In

New engines must be operated a minimum duration of two tanks of fuel
break-in before carburetor adjustments can be made. During the break-in
period your engine performance will increase and exhaust emissions will
stabilize. Idle speed can be adjusted as required.

High Altitude Adjustment

This engine has been factory adjusted to maintain satisfactory starting,
emission, and durability performance up to 1,000 feet above mean sea
level (MSL). To maintain proper engine operation above 1,000 feet MSL
the carburetor must be adjusted by an authorized ECHO service dealer.

IMPORTANT

If the engine is adjusted for operation above 1,000 feet MSL, the
carburetor must be re-adjusted when operating the engine below
1,000 feet MSL, otherwise severe engine damage can result.

Level 2.

Tools required: Screwdriver, tachometer (Echo P/N 99051130017)

Parts required: None.

NOTE

Do not adjust carburetor unless necessary. If you have difficulty,
see your ECHO dealer.

Adjustment Screws

Idle Speed (A) Controls throttle opening at idle.

Low (LO) Speed (B) Controls amount of fuel at low speed and

supplementary fuel for smooth progression from
idle to high speed.

High (HI) Speed (C) Controls amount of fuel at full throttle

Before Adjustment

Check that:

• Air filter is clean and properly installed.

• Spark arrestor screen and muffler are free of carbon.

A

C

B

• Blower pipes are installed.

24

Initial Adjustment

1 . With engine off, turn HI speed screw (C) counterclockwise to stop.

2 . Turn LO speed screw (B) midway between stops.

3 . Turn idle screw (A) until tip of screw just touches throttle plate;

then turn three (3) turns clockwise.

Final Adjustment

IMPORTANT

Limiter caps prevent exceeding emission limits and over rich
adjustment, but not over lean adjustment, which can cause
engine failure: Do not exceed recommended HI speed engine
R.P.M. during operation, or for long periods during adjustment.

1 . Start engine, run at idle for one minute.

2 . Complete warm up by running at full throttle for 5 minutes, operat-

ing choke twice to clear air from carburetor chambers.

3 . Run at idle and accelerate to check for smooth transition from idle

to high speed; if engine hesitates, turn LO speed screw (B)
counterclockwise 1/8th of a turn at a time until acceleration is
smooth.

4. Use a tachometer to adjust idle speed to specifications found on
page 27.
