Vibration and Cold
It is believed that a condition called Raynaud’s Phenomenon, which affects the ngers of certain individuals may be
brought about by exposure to vibration and cold. Exposure to vibration and cold may cause tingling and burning sen-
sations followed by loss of color and numbness in the ngers. 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 ll 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 ngers
followed by whitening and loss of feeling, consult your physician
before further exposing yourself to cold and vibration.
personal CondITIon and safeTy equIpmenT
WARNING
Users of this product risk injury to themselves and others if the unit is used improperly and/or safety precautions
are not followed. Proper clothing and safety gear must be worn when operating unit.
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 re-
quirements whenever you operate the unit
Face and Head Protection
When trimming overhead, always wear head protection
meeting ANSI Z89.1 or CE requirements with a full face
shield. Head protection with full face shield will help
protect you from falling branches and debris.
Hand Protection
Wear no-slip, heavy duty work gloves to improve your
grip on the unit handles. Gloves also reduce the transmis-
sion of machine vibration to your hands.
Proper Clothing
Wear snug tting, durable clothing;
• Pants should have long legs, shirts with long sleeves.
• DO NOT WEAR SHORTS,
• DO NOT WEAR TIES, SCARVES, JEWELRY,
or clothing with loose or hanging items that could
become entangled in moving parts or surrounding
growth.
Wear sturdy work shoes with nonskid soles;
• DO NOT WEAR OPEN TOED SHOES,
• DO NOT OPERATE UNIT BAREFOOTED.
Wear no-slip, heavy duty work gloves.
Keep long hair away from engine and air 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.
WARNING
The ignition components of this machine generate an electromagnetic eld during operation which may interfere
with some pacemakers. To reduce the risk of serious or fatal injury, persons with pacemakers should consult with
their physician and the pacemaker manufacturer before operating this machine. In the absence of such informa-
tion, ECHO does not recommend the use of ECHO products by anyone who has a pacemaker.
Hearing Protection
ECHO recommends wearing hearing protection whenever
unit is used.
Power PrunerTM
oPeraTor's Manual 5
DANGER
All over head electrical conductors and communications wires can
have electricity ow with high voltages. This unit is not insulated
against electrical current. Never touch wires directly or indirectly
when pruning, otherwise serious injury or death may result.
WARNING
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.
Use Proper Clothing & Equipment
• Always wear head protection with full face shield to help protect
against falling branches and debris.
Keep A Firm Grip
• Grip Power PrunerTM with both hands with thumbs and ngers encir-
cling the handle, and shaft tube.
Repetitive Stress Injuries
It is believed that overusing the muscles and tendons of the ngers, 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. In-
stead try to maintain a straight wrist position. Also, when grasping,
use your whole hand, not just the thumb and index nger.
• Take periodic breaks to minimize repetition and rest your hands.
• Reduce the speed and force with which you do the repetitive move-
ment.
• 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 ngers, hands, wrists or
arms. The sooner RSI/CTS is diagnosed, the more likely permanent
nerve and muscle damage can be prevented.

WARNING
Kickback can lead to dangerous loss of control of the Power PrunerTM and result in serious injury to the operator or
any one standing close by. Hold the Power PrunerTM rmly with both hands with thumbs and ngers encircling the
front and rear handles. Be aware of the down and outward path the pruner will take after the cut is made.
kICkbaCk
Kickback may occur when the moving saw chain at 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. In some cases this may cause a lightning-fast
reverse action, kicking the guide bar and saw chain up and back or
down and back towards the operator. Either of these reactions may
cause the operator to lose control of the Power PrunerTM which could
result in serious personal injury.
With a basic understanding of kickback, you can reduce or eliminate
the element of surprise which contributes to accidents.
Avoid contact of the guide bar tip with any object while the saw chain
is moving.
Cut only wood. Avoid striking concrete, metal, wire, or other obstruc-
tions which could cause kickback or damage to the saw chain.
If the saw chain does strike a foreign object, immediately stop the en-
gine, inspect and repair the Power PrunerTM if necessary.
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 overreach.
• Operate the Power PrunerTM only from the ground or out of an ap-
proved bucket lift.
• Always evaluate the branches to be pruned for hazards such as loose
dead branches which may fall and strike the operator or helpers.
Remove hazards before pruning.
• Plan retreat path from falling objects.
• Cut branches bounce when striking ground.
• Check that shoulder harness is adjusted for safe, comfortable opera-
tion. See picture at right for proper adjustment.
• Turn the Power PrunerTM off when moving from tree to tree.
• Avoid any contact with saw chain.
Avoid Hot Surfaces
• Keep exhaust area clear of ammable debris. Avoid contact during
and immediately after operation.
Transporting Unit
• When transporting the unit, empty the fuel tank, put the unit in an
upright position, and secure it rmly. Failure to do so could result in
damage or injury.

Alternative fuels, such as E-15 (15% 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 prob-
lems, 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, carbure-
tors 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. FD Standards must be
used. Echo brand premium Power Blend X TM Universal 2-Stroke Oil meets these standards. Engine problems due to
inadequate lubrication caused by failure to use an (ISO/CD 13738) and J.A.S.O. FD certied oil, such as Echo premium
Power Blend X TM, will void the two-stroke engine warranty.
IMPORTANT
Echo premium Power Blend X TM Universal 2-Stroke Oil may be mixed at 50:1 ratio for application in all Echo en-
gines sold in the past regardless of ratio specied in those manuals.

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, close fuel container, and remix.
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.
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 gov-
ernment 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 ames.
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 con-
tainer thoroughly before each use.
Handling Fuel
DANGER
Fuel is VERY ammable. Use extreme care when mixing, storing or handling or serious personal injury may result.
• Use an approved fuel container.
• DO NOT smoke near fuel.
• DO NOT allow ames or sparks near fuel.
• Fuel tanks/cans may be under pressure. Always loosen fuel caps slowly allowing pressure to equalize.
• NEVER refuel a unit when the engine is HOT or RUNNING!
• DO NOT ll fuel tanks indoors. ALWAYS ll fuel tanks outdoors over bare ground.
• DO NOT overll fuel tank. Wipe up spills immediately.
• Securely tighten fuel tank cap and close fuel container after refueling.
• Inspect for fuel leakage. If fuel leakage is found, do not start or operate unit until leakage is repaired.
• Move at least 3m (10 ft.) from refueling location before starting the engine.

1. Wipe debris from around oil ll cap.
2. Remove oil ll cap and ll reservoir with a quality, low viscosity
guide bar and saw chain oil.
IMPORTANT
To prevent plastic deterioration, do not use synthetic or silicone
based oil.
adjusTIng auTomaTIC oIler
1. From bottom of gear case, turn adjustment screw (A) clockwise to
decrease oil volume - counter clockwise to increase oil volume.
NOTE
The automatic oiler is preset to deliver a sufcient oil discharge
volume during normal operating conditions. During heavy or dry
cutting conditions, the oil discharge volume may be increased to as-
sure adequate lubrication. If oil is leaking from the bar cover area,
reduce the oil discharge volume. Rell the oil reservoir with each
tank of fuel.
NOTE
Very little visible oil on the saw chain will provide sufcient lubri-
cation.

WARNING
Engine exhaust IS HOT, and contains Carbon Monoxide (CO), a
poison gas. Breathing CO can cause unconsciousness, serious in-
jury, or death. Exhaust can cause serious burns. ALWAYS position
unit so that exhaust is directed away from your face and body.
The Power PrunerTM is designed for light to medium trimming of limbs
and branches up to 203 mm (8 in.) in diameter. Follow these tips for
successful operation.
• Plan cut carefully. Check direction branch will fall.
• Plan retreat path from falling branch. Cut branches bounce when
striking ground.
• Long branches should be removed in several pieces.
• Do not stand directly beneath branch being cut.
• When ready to cut:
Hold "cutting shoe" against branch. This will prevent whipping of the
branch. DO NOT use back and forth sawing action.
• Look out for branch immediately behind the branch being cut. If saw
chain hits rear branch damage to saw chain may occur.
• Accelerate to full throttle.
• Apply cutting pressure.
• Ease cutting pressure when nearing end of cut to maintain control.
• When pruning a limb 102 mm (4 in.) diameter or larger, cut as fol-
lows:
1. Under cut 1/4 limb diameter near tree trunk.
2. Finish top cut slightly farther out on limb.
3. Flush cut stub at trunk.
• DO NOT use for felling or bucking.

CoolIng sysTem
Level 2.
Parts Required: None if you are careful.
IMPORTANT
To maintain proper engine operating temperatures, cooling air
must pass freely through the cylinder n area. This ow 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 ns is
considered “Normal Maintenance.” Any failure attributed to lack of
maintenance is not warranted.
1. Remove spark plug lead.
2. Remove air cleaner cover.
3. Remove mufer cover (A).
