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.
• Spectators and fellow workers must be warned, and children and
animalspreventedfromcoming nearer than 15 M(50ft.)while the
Power PrunerTM 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 PrunerTM with both hands with thumbs and fingers
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 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
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
ismoving.
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.

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
recommendedbecausethe minimum exposure whichmighttriggerthe
ailmentisunknown.
• 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.
• 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.
