RESIDUAL RISK
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. Restrict working time and exposure.
■ Exposure to noise can cause hearing injury.
–
Wear hearing 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 or emission from
the petrol engine.
■ Skin contact with petrol/oil.
RISK REDUCTION
It has been reported that vibrations from handheld 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 also 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 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
minimize 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.
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 product
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 kick-back. You should use a guide bar
and matching chain, which 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 from
rotating. When the chain brake lever/hand guard 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 operators
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.
