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.

■

injury caused by noise

Exposure to noise can cause hearing injury. Wear ear
protection and limit exposure.

■

injury from contact with the exposed saw teeth of the
chain

■

injury caused by kickback or sudden and unforeseen
movement of the guide bar

■

injury caused by ejected parts of the saw chain

■

injury caused by thrown-off parts of the workpiece
(wood chips and splinters)

■

injury caused by dust and particles

■

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

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.

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.

ENVIRONMENTAL PROTECTION

Recycle raw materials instead of disposing
of as waste. The machine, accessories and
packaging should be sorted for environment-
friendly recycling.
