RESIDUAL RISKS
Even when the product is used as prescribed, it is still
impossible to eliminate certain residual risk factors. The
following hazards may arise during 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.
■ injury caused by exposure to noise
– Wear hearing protection and limit exposure.
■ injury caused by contact with exposed saw teeth of the
chain (cutting hazards)
■ injury caused by parts ejected from the saw chain
(cutting/injection hazards)
■ injury caused by thrown-out pieces of the workpiece
(wood chips, splinters)
■ injury caused by dust and particles
■ injury to the skin caused by contact with lubricants
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 fingers, 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 product, 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 reduce the effect
of handle vibration.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your physician.
WARNING
Injuries may be caused, or aggravated, by prolonged use
of the product. When using the product for prolonged
periods, ensure to take regular breaks.
SAFETY DEVICES
Low kickback saw chain
A low-kickback saw chain helpsreduce the possibility of a
kickback event.
The rakers (depth gauges) ahead of each cutter can
minimize the force of a kickback reaction by preventing the
cutters from digging in too deeply. Use only replacement
guide bar and chain combinations recommended by the
manufacturer.
As saw chains are sharpened, they lose some of the low
kickback qualities and extra caution is required. For your
safety, replace saw chains when cutting performance
decreases.
Spiked bumper
The integral bumper spike may be used as a pivot when
making a cut. It helps to keep the body of the chainsaw
steady while cutting. When cutting, push the machine
forward until the spikes dig into the edge of the wood, then
by moving the rear handle up or down in the direction of the
cutting line it can help ease the physical strain of cutting
Guide bars
Generally, guide bars with small radius tips have somewhat
lower potential for kickback. Use a guide bar and matching
chain that is just long enough for the job. Longer bars
increase the risk of loss of control during sawing. Regularly
check the chain tension. When cutting smaller branches
(less than the full length of the guide bar), the chain is more
likely to be thrown off if the tension is not correct.
Chain brake
Chain brakes are designed to quickly stop the chain
rotating. When the chain brake lever is pushed towards the
bar, the chain should stop immediately. A chain brake does
not prevent kickback. It only lowers the risk of injury should
the chain bar contact the operator’s body during a kickback
event. The chain brake should be tested before each use
for correct operation in both the run and brake positions.
Chain catcher
A chain catcher prevents the saw chain from being thrown
back towards the operator if the saw chain comes loose
or breaks.
