• if you are tired or sick,
Hearing Protection
ECHO recommends wearing hearing protection whenever
unit is used.
• if you are taking medication,
• if you have taken alcohol or drugs.
Operate unit only if you are physically and mentally well.
Proper Clothing

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.
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.
EQUIPMENT
Before operation a complete check of the unit must be performed:
• 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.

SAFE OPERATION
W ARNING DANGER
Do not operate this product indoors or in inadequately ventilated
areas. Engine exhaust contains poisonous emissions and can cause
serious injury or death.
Determine Operation Area
• Review area to be cleared. Look for potential hazards such as stones
or metal objects.
• Take wind conditions into account: avoid open doors and windows.
• Do not point blower at people or animals.
• Start unit on ground with throttle at idle. Check that blower pipe is
not blocked by the ground or by any objects.
Read the Manuals
• Provide all users of this equipment with the Operator's Manual and
Safety Manual for instructions on Safe Operation.
Keep A Firm Grip
• Hold handle with fingers together encircling the handle.
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.
Noise Control
• Follow local noise regulations on sound
levels and hours of operations. Use only
during appropriate hours.
• Never use a higher speed setting then
necessary to perform a task. The higher
the engine speed the louder the blower
noise.
• Be a good neighbor.
Avoid Hot Surfaces
• During operation, the muffler or catalytic
muffler and surrounding cover may
become extremely hot. 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.
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 perform Maintenance or Assembly procedures with engine
running.

Parts Required: None, if you are careful.
0.65 mm
(0.026 in.)
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.

CARBURETOR
ADJUSTMENT
Engine Break-In
New engines must be operated for a minimum duration of two tanks of
fuel 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
High altitude adjustment may be required for proper operation of this
engine.
IMPORTANT
For engine operation above 2,000 feet, turn the high-speed needle
lean (CW) until the engine runs between 7,000 and 8,000 RPM. Then
turn the low-speed needle lean (CW) until the engine does not
hesitate on acceleration.
For engine operation below 2,000 feet, turn the high-speed needle
rich (CCW) until the engine runs between 7,000 and 8,000 RPM.
Then turn the low-speed needle rich (CCW) until the engine does
not hesitate on acceleration.
DO NOT REMOVE LIMITER CAPS!
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) Control 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.
• Blower pipes are installed.
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 C.A.R.B. and E.P.A. 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 9.
