RESIDUAL RISKS

Even when the product is used as prescribed, it is still
impossible to completely eliminate certain residual risk
factors. The following hazards may arise in use and the
operator should pay special attention to avoid the following:
■ Injury caused by vibration. Always use the right tool for
the job, use designated handles and restrict working
time and exposure.
■ Exposure to noise can cause hearing injury. Wear ear
protection and limit exposure
■ Contact with exposed saw teeth of the chain (cutting
hazards).
■ Unforeseen, abrupt movement or kickback of the guide
bar (cutting hazards).
■ Parts ejected from the saw chain (cutting/injection
hazards).
■ Thrown out pieces of the work piece (wood chips,
splinters)
■ Inhalation of saw dust and particles.
■ Skin contact with lubricant/oil.

RISK REDUCTION

It has been reported that vibrations from hand-held tools
may contribute to a condition called Raynaud's Syndrome
in certain individuals. Symptoms may include tingling,
numbness and blanching of the fi ngers, usually apparent
upon exposure to cold. Hereditary factors, exposure to
cold and dampness, diet, smoking and work practices
are all thought to contribute to the development of these
symptoms. There are measures that can be taken by the
operator to possibly reduce the effects of vibration:
■ Keep your body warm in cold weather. When operating
the unit wear gloves to keep the hands and wrists
warm. It is reported that cold weather is a major factor
contributing to Raynaud's Syndrome.
■ After each period of operation, exercise to increase
blood circulation.
■ Take frequent work breaks. Limit the amount of
exposure per day.
■ Protective gloves available from professional chainsaw
retailers are designed specifically for chainsaw use
which give protection, good grip and also reduce the
effect of handle vibration.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your doctor about
these symptoms.
WARNING
Injuries may be caused, or aggravated, by prolonged
use of a tool. When using any tool for prolonged periods,
ensure you take regular breaks.
SAFETY DEVICES
LOW KICKBACK SAW CHAIN
A low-kickback saw chain helps to reduce the possibility of
a kickback event.
The rakers (depth gauges) ahead of each cutter can
minimise the force of a kickback reaction by preventing the
cutters from digging in too deeply. Only use replacement
guide bar and chain combinations recommended by the
manufacturer.
As saw chains are sharpened, they lose some the low
kickback qualities and extra caution is required. For your
safety, replace saw chains when cutting performance
decreases.
GUIDE BARS
Generally, guide bars with small radius tips have somewhat
lower potential for kickback. Only use replacement
guide bar and chain combinations recommended by the
manufacturer. The use of unrecommended guide bars
increase the risk of loss of control during sawing.
