PERSONAL CONDITION & SAFETY EQUIPMENT

W ARNING DANGER

Power Pruner users risk injury to themselves and others if the Power Pruner is used improperly and or safety precautions are not followed. Proper clothing and safety gear must be worn when operating a Power Pruner.

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 --

Eye protection that meet ANSI Z87.1 and CE requirements were included with your Power Pruner. Wear them whenever you operate the Power Pruner.

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 pruner handles. Gloves also reduce the transmission of machine vibration to your hands. Special vibration reducing gloves such as Echo's Pro-Comfort are designed to provide additional comfort.

Hearing Protection --

Wear hearing protection. OSHA requires the use of hearing protection if this unit is used 2 hours per day or more. 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.

Wear sturdy work shoes with non-skid soles;

• DO NOT WEAR OPEN TOED SHOES,

• DO NOT OPERATE UNIT BAREFOOTED.

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.

SAFE OPERATION

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.

POWER PRUNER

OPERATOR'S MANUAL

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 Pruner 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.

Keep A Firm Grip

• Grip Power Pruner with both hands with thumbs and fingers tightly 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 Pruner 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 Pruner 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 Pruner and result in serious injury to the operator or any one standing close by.

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.

Hold the Power Pruner firmly with both hands. Be aware of the down and outward path the pruner will take after the cut is made.

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 Pruner if necessary.

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.

• 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.

POWER PRUNER

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.

• See 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.

POWER PRUNER

OPERATOR'S MANUAL

PRUNING TECHNIQUES

The Power Pruner 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.

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 . 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.

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.

POWER PRUNER

OPERATOR'S MANUAL

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 FIL TER

Level 1.

Parts Required: 90008 REPOWER FILTER KIT

WARNING DANGER

Fuel is VERY flammable. Use extreme care when mixing, storing or handling or serious personal injury may result.

1 . Use a clean rag to remove loose dirt from around fuel cap and

empty fuel tank.

2. Use the “fuel line hook” to pull the fuel line and filter from the tank. 3 . Remove the filter from the line and install the new filter.

SPARK PLUG

COOLING SYSTEM CLEANING

Level 3.

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.

0.65 mm

(0.026 in.)

Removal of cooling passage blockages or cleaning of cooling fins is considered “Normal Maintenance”. Any failure attributed to lack of maintenance is not warranted.

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 pruner.

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.
