EXTENDED OPERATION/EXTREME CONDITIONS  
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.  
To reduce the risk of RSI/CTS, do the  
following:  
• Avoid using your wrist in a bent, ex-  
tended, 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.  
• Takeperiodicbreakstominimizerepetition  
and rest your hands.  
• Reduce the speed and force with which  
you do the repetitive movement.  
• Do exercises to strengthen the hand and  
armmuscles.  
• Immediately stop using all power equip-  
ment 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 perma-  
nent nerve and muscle damage can be  
prevented.  
• 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). AnextremeRSIconditionisCarpalTunnelSyndrome  
(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.  
EQUIPMENT  
WARNING  
DANGER  
Serious injury may result from the use of non-approved guide bar and saw chain combinations. ECHO, INC. will not  
be responsible for the failure of cutting devices or accessories which have not been tested and approved by ECHO  
for use with this unit. Read and comply with all safety instructions listed in this manual.  
• 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.  
• Keepexhaustareaclearofflammable  
debris. Avoid contact during and immedi-  
ately after operation.  
Guide Bar and Saw Chain  
• Check that the cutting attachment, guide bar, and saw chain is firmly  
attached and in safe operating condition.  
• Use only one Echo-approved extension on the pruner.  
• Do not hit rocks, stones, tree stumps, and other foreign objects with  
the saw chain.  
• Do not cut into the ground with the saw chain.  
• If cutting attachment end strikes an obstruction, stop engine immedi-  
ately and inspect saw chain for damage.  
• Do not operate with a dull, fractured, or discolored saw chain.  
• Remove all foreign objects from work area.  
• Always cover the guide bar and saw chain with guide bar cover  
during transportation and for storage.

SAFE OPERATION  
WARNING  
KeepASolidStance  
• 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.  
DANGER  
All overhead 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.  
• Plan retreat path from falling objects.  
• Cut branches bounce when striking  
ground.  
WARNING  
DANGER  
Do not operate this product indoors or in inadequately ventilated  
areas. Engine exhaust contains poisonous emissions and can cause  
serious injury or death.  
• Check that shoulder harness is adjusted  
for safe, comfortable operation.  
• Turn the Power PrunerTM off when moving  
from tree to tree.  
ReadtheManuals  
• Provide all operators of this equipment with the Operator's Manual,  
and instructions for safe operation.  
• Avoid any contact with saw chain.  
• Avoid all power lines. This unit is not insulated against electrical  
current.  
UseProperClothing&Equipment  
• Always wear head protection with full face shield to help protect  
against falling branches and debris.  
KeepAFirmGrip  
• Grip Power PrunerTM with both hands with thumbs and fingers  
encircling the handle, and shaft tube.  
KICKBACK  
WARNING  
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 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  
engine, inspect and repair the Power PrunerTM if necessary.

PRUNING TECHNIQUES  
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.  
CORRE
• Plancutcarefully. Checkdirectionbranchwillfall.  
• Plan retreat path from falling branch. Cut branches bounce when  
striking ground.  
GUIDE
BR
• Long branches should be removed in several pieces.  
• Do not stand directly beneath branch being cut.  
• When ready to cut:  
NOT  
CORRECT  
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.  
BLADEHITSREARBRANCH  
• 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 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.

Tools required: Cleaning brush 25 or 50 mm (1 or 2 in.)  
Parts required: 90008REPOWERTM AirandFuelFilterKit  
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.  
3. If element can be cleaned and reused, be certain it:  
• properly fits the cavity in the air cleaner cover.  
• is installed with the original side out.  
NOTE  
Carburetor adjustment may be needed after air filter cleaning/  
replacement. See Carburetor Adjustment Section.  
FUEL FILTER  
Level1.  
Tools required: 200-250 mm ( 8 - 10 in.) length of wire with one end  
bent into a hook. Clean rag, funnel, and an approved  
fuel container

COOLING SYSTEM CLEANING  
Level2.  
Tools required: 4mmHexwrench, Cleaning brush 25 - 50 mm  
(1-2in.)  
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.
