English ￭ The saw chain has many sharp cutters. If they contact your flesh, they will cut you even if the chain is not moving. - Always wear heavy-duty work gloves when handling the saw or its chain. - Keep hands, feet and other parts of your body away from the chain. ￭ Reactive forces, including kickback, can be dangerous. - Pay special attention to the sections of this instruction manual dealing with reactive forces. ￭ Observe all applicable federal, state and local safety regulations, standards and ordinances. - When using a chain saw for logging purposes, for instance, refer to the OSHA regulations for "logging operations" at 29 Code of Federal Regulations 1910.266. ￭ Improper use could result in personal injury or property damage, including damage to the chain saw. - Use the chain saw, battery and charger only as described in this manual. - Never attempt to modify or override the chain saw's controls or safety devices in any way. - Never use a chain saw that has been modified or altered from its original design. ￭ The STIHL AK series battery is designed for use only with compatible STIHL power tools. ￭ The STIHL AL 101, AL 300 or AL 500 series charger is designed for charging STIHL AK and AP series batteries only. 6 IMPORTANT SAFETY INSTRUCTIONS 6.2 Operator WARNING ￭ Working with the chain saw can be strenuous. The operator must be in good physical condition and mental health. To reduce the risk of personal injury from fatigue and loss of control: - Check with your doctor before using the chain saw if you have any health condition that may be aggravated by strenuous work. - Do not operate the chain saw 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 chain saw when you are tired. Take a break if you become tired. - Do not permit minors to use the chain saw. - Bystanders, especially children, and animals should not be allowed in the area where the chain saw is in use. ￭ Prolonged use of a chain saw (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 disease 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 exposure to vibration, are mentioned as factors in the development of white finger disease. ￭ To reduce the risk of white finger disease and carpal tunnel syndrome: - Wear gloves while working and keep your hands warm. - Keep the chain saw well maintained. An improperly maintained chain saw or one with loose components will tend to have higher vibration levels. 10 0458-716-8621-E

6 IMPORTANT SAFETY INSTRUCTIONS

￭

The saw chain has many sharp cutters. If they contact

your flesh, they will cut you even if the chain is not moving.

–

Always wear heavy-duty work gloves when handling

the saw or its chain.

–

Keep hands, feet and other parts of your body away

from the chain.

￭

Reactive forces, including kickback, can be dangerous.

–

Pay special attention to the sections of this

instruction manual dealing with reactive forces.

￭

Observe all applicable federal, state and local safety

regulations, standards and ordinances.

–

When using a chain saw for logging purposes, for

instance, refer to the OSHA regulations for "logging

operations" at 29 Code of Federal Regulations

1910.266.

￭

Improper use could result in personal injury or property

damage, including damage to the chain saw.

–

Use the chain saw, battery and charger only as

described in this manual.

–

Never attempt to modify or override the chain saw's

controls or safety devices in any way.

–

Never use a chain saw that has been modified or

altered from its original design.

￭

The STIHL AK series battery is designed for use only with

compatible STIHL power tools.

￭

The STIHL AL 101, AL 300 or AL 500 series charger is

designed for charging STIHL AK and AP series batteries

only.

6.2

Operator

WARNING

￭

Working with the chain saw can be strenuous. The

operator must be in good physical condition and mental

health. To reduce the risk of personal injury from fatigue

and loss of control:

–

Check with your doctor before using the chain saw if

you have any health condition that may be

aggravated by strenuous work.

–

Do not operate the chain saw 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 chain saw when you are

tired. Take a break if you become tired.

–

Do not permit minors to use the chain saw.

–

Bystanders, especially children, and animals should

not be allowed in the area where the chain saw is in

use.

￭

Prolonged use of a chain saw (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 disease 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

exposure to vibration, are mentioned as factors in the

development of white finger disease.

￭

To reduce the risk of white finger disease and carpal

tunnel syndrome:

–

Wear gloves while working and keep your hands

warm.

–

Keep the chain saw well maintained. An improperly

maintained chain saw or one with loose components

will tend to have higher vibration levels.
