Original instructions | English

■ Any part that is damaged should be properly repaired or

replaced by an authorised service centre.

■ Check all nuts, bolts, and screws at frequent intervals

for proper tightness to ensure the product is in a safe
working condition.

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
– Hold the product by designated handles and restrict

working time and exposure.

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

■ Eye injury due to flying debris
– Wear eye protection at all times.

RISK REDUCTION

It has been reported that vibrations from handheld tools
may contribute to a condition called Raynaud’s Syndrome.
Symptoms may include tingling, numbness and blanching

of the 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 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.

If you experience any of the symptoms of this condition,
immediately discontinue use and see your physician.

Wear eye, hearing, and head protection
when operating the product.

Beware of thrown or ying objects. Keep

all bystanders, especially children and
pets, at least 15 m from the operating
area.

Wear non-slip safety footwear when
using the product.

Wear non-slip, heavy duty gloves.

Do not use blade(s) on the product.
