Operator

WARNING

■ Working with the trimmer / brushcutter can be

strenuous. The operator must be in good

physical condition and mental health. To

reduce the risk of personal injury:

► Check with your doctor before using the

trimmer / brushcutter if you have any health

condition that may be aggravated by stren‐

uous work.

► Do not operate the trimmer / brushcutter

while under the influence of any substance

(drug, alcohol or medication, etc.) that

might impair vision, balance, dexterity or

judgment.

► Be alert. Do not operate the trimmer /

brushcutter when you are tired. Take a

break if you become tired.

► Do not permit minors to use the trimmer /

brushcutter.

► Bystanders, especially children, and ani‐

mals should not be allowed in the area

where the trimmer / brushcutter is in use.

■ Prolonged use of a trimmer / brushcutter (or

other power tools) exposing the operator to

vibration may produce white finger disease

(Raynaud's phenomenon) or carpal tunnel

syndrome. These conditions reduce the hand's

ability to feel and regulate temperature. They

produce numbness and burning sensations

and may also cause nerve and circulation

damage as well as tissue necrosis.

■ All factors which contribute to white finger dis‐

ease are not known. Cold weather, smoking

and diseases or physical conditions that affect

blood vessels and blood transport, as well as

high vibration levels and long periods of expo‐

5 IMPORTANT SAFETY INSTRUCTIONS

sure to vibration, are mentioned as factors in

the development of white finger disease.

■ STIHL trimmer / brushcutters are equipped

with an anti-vibration ("AV") system designed

to reduce the transmission of vibration from

the trimmer / brushcutter to the operator's

hands. To reduce the risk of white finger dis‐

ease and carpal tunnel syndrome:

► Wear gloves while working and keep your

hands warm.

► Keep the trimmer / brushcutter and its AV

system well maintained. A trimmer / brush‐

cutter with loose components or with dam‐

aged or worn AV elements will tend to have

higher vibration levels.

► Maintain a firm grip at all times, but do not

squeeze the handles with constant, exces‐

sive pressure. Take frequent breaks.

■ These precautions do not guarantee that you

will not sustain white finger disease or carpal

tunnel syndrome.

► Closely monitor the condition of your hands

and fingers if you are a regular operator.

► Seek medical advice immediately if any of

the above symptoms appear.

■ The ignition system of this machine produces

an electromagnetic field of a very low intensity.

This field may interfere with some pacemakers

or implanted medical devices. To reduce the

risk of injury:

► Persons with a pacemaker or other implan‐

ted medical device should consult their

physician and the device manufacturer

before operating this trimmer / brushcutter.
