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 armexercises
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). 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.
• 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.
EQUIPMENT
• 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.
• Never adjust blades when the engine is operating.
• Inspect hand guard for damage. Replace if damaged or missing.
• Check that the blade assembly is firmly attached and in safe operating
condition. Dull, loose or damaged blades should not be used.
• Keep exhaust area clear of flammable debris. Avoid contact during
and immediately after operation.
