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  
WARNING  
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.  
15 M  
(50ft.)  
• 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  
UseProperClothing&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.  
AvoidHotSurfaces  
• 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.

KeepAFirmGrip  
• Grip Power Pruner with both hands with thumbs and fingers tightly  
encircling the handle, and lower shaft tube.  
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 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  
WARNING  
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 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 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.  
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.  
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.

PRUNING TECHNIQUES  
CORRECT  
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 success-  
ful operation.  
• Plancutcarefully. Checkdirectionbranchwillfall.  
AGAINST  
BRANCH  
• Plan retreat path from falling branch. Cut branches bounce when  
striking ground.  
NOT  
• 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.  
BLADEHITSREARBRANCH  
• 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 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.  
NOT  
CORRECT  
• DO NOT use for felling or bucking.

COOLING SYSTEM CLEANING  
Level3.  
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.  
A
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.
