EXTENDED OPERATION/EXTREME CONDITIONS
Vibration and Cold
To reduce the risk of RSI/CTS, do the
following:
It is believed that a condition called Raynaud’s Phenomenon, which
affects the fingers of certain individual 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.
• 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.
• Keep your body warm, especially the head, neck, feet, ankles, hands,
and wrists.
• 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.
• Maintain good blood circulation by performing vigorous arm exer-
cises during frequent work breaks, and also by not smoking.
• Limit the hours of operation. Try to fill each day with jobs where
operating the blower 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
Before operation a complete check of the unit must be performed:
• 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.

or metal objects.
• Take wind conditions into account: avoid open doors and windows.
• Do not point blower at people or animals.
• Start unit on ground with throttle at idle. Check that blower pipe is
not blocked by the ground or by any objects.
• Be a good neighbor.
ReadtheManuals
• Provide all users of this equipment with the Operator's Manual and
Safety Manual for instructions on Safe Operation.
AvoidHotSurfaces
• During operation, the muffler or catalytic
muffler and surrounding cover may
become extremely hot. Avoid contact
during and immediately after operation.
Always keep exhaust area clear of
flammabledebris.
KeepAFirmGrip
• Hold handle with fingers together encircling the handle.
CleartheWorkArea
• Spectators and fellow workers must be warned, and children and
animals prevented from coming nearer than 15 m (50 ft.) while the unit
is in use.

COOLING SYSTEMS CLEANING
Level2.
Tools required: 25 - 50 mm (1 - 2 in.) Cleaning brush, cross head

Parts Required: None, if you are careful.
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.
B
Cleaning Grill
1. Remove accumulated debris from intake grill (A) between back-
pack frame and blower housing.
Cleaning Cylinder Fins
1. Remove engine cover (five screws), pull cover away from engine.
Clean cylinder fins (B) to allow cooling air to pass freely.
