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 requirements 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 transmission of machine vibration to your hands.

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, 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 field 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 information, ECHO does not recommend the use of ECHO products by anyone who has a pacemaker.

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 PrunerTM
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

All over head electrical conductors and communications wires can
have electricity flow 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 fingers encircling the handle, and shaft tube.

6
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 approved 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 operation. 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 flammable 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 firmly. Failure to do so could result in
damage or injury.

kickback

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 firmly with both hands with thumbs and fingers encircling the
front and rear handles. Be aware of the down and outward path the pruner will take after the cut is made.
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 obstructions which could cause kickback or damage to the saw chain.
If the saw chain does strike a foreign object, immediately stop the engine, inspect and repair the Power PrunerTM if necessary.

fuel
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.

WARNING

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 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)

• NEVER refuel a unit when the engine is HOT or RUNNING!
• DO NOT fill fuel tanks indoors. ALWAYS fill fuel tanks outdoors over bare ground.
• DO NOT overfill 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.
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 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.

pruning techniques

WARNING

Engine exhaust IS HOT, and contains Carbon Monoxide (CO), a
poison gas. Breathing CO can cause unconsciousness, serious injury, 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.

CORRECT

• 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.

GUIDE AGAINST
BRANCH

• 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.

NOT
CORRECT

• 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.

BLADE HITS REAR BRANCH

• Ease cutting pressure when nearing end of cut to maintain control.
• When pruning a limb 102 mm (4 in.) diameter or larger, cut as follows:
1.
2.
3.

Under cut 1/4 limb diameter near tree trunk.
Finish top cut slightly farther out on limb.
Flush cut stub at trunk.

• DO NOT use for felling or bucking.
NOT
CORRECT

performance. To help ensure the performance of the unit, it is required to use two-stroke oil which meets the ISO-L-EGD Standard per ISO/CD
13738 and JASO M345FD Standards. ECHO Power Blend™ Two-Stroke Oil is a premium two-stroke oil specifically formulated to meet ISOL-EGD (ISO/CD 13738) and JASO M345FD Standards. The use of two-stroke oils designed for other applications, such as for outboard motors

oil, will void the two-stroke engine limited warranty. ECHO Power Blend™ Two-Stroke Oil meets the ISO-L-EGD and JASO M345FD
Standard. Emission related parts are covered for 5 years residential use or 2 years commercial use regardless of two-stroke oil used, per
the statement listed in the EPA or California Emission Defect Warranty Explanation.
•
damage caused by use of gasohol, containing methanol (wood alcohol), or gasoline containing less than 89 octane. Only use gasoline which
contains 89 octane or higher. Gasohol which contains a maximum 10% ethanol (grain alcohol) or 15% MTBE (methyl/tertiary/butyl/ether)
is also approved. The prescribed mixing ratio of gasoline to oil is listed on the ECHO oil label and covered in your operator’s manual.
•
Engine damage caused by use of ether or any starting fluids.
•
damage caused by tampering with engine speed governor or emission components, or running engines above specified and recommended
engine speeds as listed in your operator’s manual.
•
Operation of the unit with improperly maintained/removed cutting shield or removed/damaged air filter.
•
damage caused by dirt, pressure or steam cleaning the unit, salt water, corrosion, rust, varnish, abrasives, and moisture.
•
defects, malfunctions or failures resulting from abuse, misuse, neglect, modifications, alterations, normal wear, improper servicing, or use
of unauthorized attachments.
•
Incorrect storage procedures, stale fuel, including failure to provide or perform required maintenance services as prescribed in the operator's
manual. Preventative maintenance as outlined in the operators manual is the customer’s responsibility.
•
Failures due to improper set-up, pre-delivery service or repair service by anyone other than authorized ECHO servicing dealer during the
warranty period.

Manuals.
•
Overheating or carbon scoring failures due to restricted, clogged exhaust port or combustion chamber, including damage to spark arrester
screen.
•
Adjustments after the first (30) thirty days and beyond, such as carburetor adjustment and throttle cable adjustment.
•
damage to gears or gear cases caused by contaminated grease or oil, use of incorrect type or viscosity of lubricants, and/or failure to comply
with recommended grease or oil change intervals.
•
damage caused by loading SHREd 'N' VAC® beyond recommended capacity.
•
damage caused by pump or sprayer running dry, pumping or spraying caustic or flammable materials, or lack of or broken strainers.
•
Additional damage to parts or components due to continued use after operational problem or failure occurs. Should operational problem or
failure occur, the product should not be used, but delivered as is to an authorized ECHO servicing dealer.
