PERSONALCONDITION&SAFETYEQUIPMENT
W ARNING DANGER
Power PrunerTM users risk injury to themselves and others if the Power PrunerTM is used improperly and or safety
precautions are not followed. Proper clothing and safety gear must be worn when operating a Power PrunerTM.
Physical Condition --
Your judgment and physical dexterity may not be good:
• if you are tired or sick,

• 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 Power PrunerTM.
Face & 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
Power PrunerTM 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 protective clothing; chain saw safety pants
or chaps are recommended.
• Pants should have long legs, shirts with long sleeves.
• DO NOT WEAR SHORTS,
• DO NOT WEAR TIES, SCARVES, JEWELRY.
Wear sturdy protective safety shoes or boots with non-skid soles;
• DO NOT WEAR OPEN TOED SHOES,
• DO NOT OPERATE UNIT BAREFOOTED.
Page 7
O
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.
SAFEOPERATION
W ARNING DANGER
All over head electrical conductors and communications wires can
have electricity flow with high voltages. Never touch wires directly
or indirectly when pruning, otherwise serious injury or death may
result.

Determine Operation Area
• Provide all operators of this equipment with the Operator's Manual
and instructions for safe operation.
• Do not operate this product indoors or in inadequately ventilated
areas.
• Review the area to be trimmed. Look for hazards that could contribute
to unsafe conditions. DO NOT operate unit if any wires (power,
telephone, cable, etc.) are closer than 15 M (50 ft.) to any part of the
operator or unit.
• Spectators and fellow workers must be warned, and children and
animals prevented from coming nearer than 15 M (50 ft.) while the
Power PrunerTM is in use.
• Avoid all power lines. This unit is not insulated against electrical
current.
Operation
Use Proper Clothing & Equipment
• Before starting the unit, equip yourself and any other person
working within the 15 M (50 ft.) Safety Zone with the required
Protective Equipment and clothing.
• Always wear head protection with full face shield to help protect
against falling branches and debris.
15 M
(50 ft.)
Avoid Hot Surfaces
• During operation, the complete unit, especially the power head,
muffler area and cutting attachment may become very hot, too hot to
touch. Avoid contact during and immediately after operation.
Page 8

Keep A Firm Grip
• Grip Power PrunerTM with both hands with thumbs and fingers
encircling the handle, and lower shaft tube.
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.
• Cut branches bounce when striking ground.
• Plan retreat path from falling objects.
• 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.
KICKBACK
W ARNING DANGER
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 Pruner
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.
TM
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.

EXTENDEDOPERATION/EXTREMECONDITIONS
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 trimmer 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.

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.

2 .Finish top cut slightly farther out on limb.
3. Flush cut stub at trunk.
• DO NOT use for felling or bucking.

MAINTENANCE
Your ECHO Power PrunerTM is designed to provide many hours of trouble free service. Regular scheduled maintenance
will help your pruner achieve that goal. If you are unsure or are not equipped with the necessary tools, you may want to
take your unit to an ECHO Service Dealer for maintenance. To help you decide whether you want to DO-IT-YOURSELF
or have the ECHO Dealer do it, each maintenance task has been graded. If the task is not listed see your ECHO Dealer for
repairs.
SKILLLEVEL
Level 1 =Easy to do. Most required tools come with unit.
Level 2 =Moderate difficulty. Some specialized tools may be required.
Level 3 =Experience required. Specialized tools are required. ECHO recommends that
the unit be returned to your ECHO dealer for servicing.
ECHO offers REPOWERTM Maintenance Kits and Parts to make your maintenance job easier. Just below each task
heading are listed the various part numbers required for that task. See your ECHO dealer for these parts.
Tools required: 25 or 50 mm (1 or 2 in.) medium bristle paint brush
Parts required: 90008 REPOWERTM FILTER KIT
1 . Close choke (Cold Start Position). This prevents dirt from entering
the carburetor throat when the air filter is removed. Brush accumulated dirt from the air cleaner area.
2 . Remove the air cleaner cover. Clean and inspect the element for
damage. If element is fuel soaked and very dirty, replace.

Level 2.
Tools required: Screwdriver, 3 mm Hex wrench, Pointed Wood Stick,
25 or 50 mm (1 in. or 2 in.) medium bristle paint brush
Parts Required: None.
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.
A
1 .Remove spark plug lead from spark plug and throttle linkage end
from the carburetor swivel.
2 .Remove the four screws that retain the engine cover (A). Two at
the top of the recoil starter, two on either side of the front. Lift the
cover from the engine and lay to the front of the Power PrunerTM.
Page 27
NOTE
The throttle linkage remains assembled to the engine cover and the
spark plug lead and grommet remain installed.
3 .Use the wooden stick or brush to remove dirt form cylinder fins.
4 .Remove grass and leaves from the grid between the recoil starter
and fuel tank.
5.Assemble components in reverse order.
NOTE
When installing the engine cover, be certain the tab of the metal
deflector shield is in the slot of the engine cover.
