Extended Operation / Extreme Conditions
Prolonged exposure to cold and/or vibration may result in injury.
Read and follow all safety and operation instructions to minimize
risk of injury. Failure to follow instructions may result in painful
wrist/hand/arm injuries.
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 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 (RSI)
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 exercise 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.
All over head electrical conductors and communications wires can
have electricity flow with high voltages. This unit is not insulated
against electrical current. Never touch wires directly or indir ectly,
otherwise serious injury or death may result.
Do not operate this product indoors or in inadequately ventilated
areas. Engine exhaust contains poisonous emissions and can
cause serious injury or death.

prevented from coming nearer than 15 m (50 ft.) while the unit is in use.
Keep a Firm Grip
• Always hold throttle handle and support handle with thumbs and fingers
tightly encircling the handles.
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 over
reach.
Avoid Hot Surfaces
• Keep exhaust area clear of flammable
debris. Avoid contact during and
immediately after operation.

4.Tighten spark plug to 150 -170
kgf•cm (130-150 in•lbf).
T o maintain proper engine operatin g 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.
