6 IMPORTANT SAFETY INSTRUCTIONS English 5.9 Causes and Operator Prevention of Kickback a) Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut. b) Tip contact in some cases may cause a sudden reverse reaction, kicking the guide bar up and back towards the operator. c) Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator. d) Either of these reactions may cause you to lose control of the saw which could result in serious personal injury. Do not rely exclusively upon the safety devices built into your saw. As a chain saw user, you should take several steps to keep your cutting jobs free from accident or injury. e) Kickback is the result of chain saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below: 1) Maintain a firm grip, with thumbs and fingers encircling the chain saw handles, with both hands on the saw and position your body and arm to allow you to resist kickback forces. Kickback forces can be controlled by the operator, if proper precautions are taken. Do not let go of the chain saw. 2) Do not overreach and do not cut above shoulder height. This helps prevent unintended tip contact and enables better control of the chain saw in unexpected situations. 3) Only use replacement guide bars and saw chains specified by the manufacturer. Incorrect replacement guide bars and saw chains may cause chain breakage and/or kickback. 4) Follow the manufacturer's sharpening and maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback. 6 IMPORTANT SAFETY INSTRUCTIONS 6.1 Intended Use WARNING ￭ This chain saw is designed for cutting small diameter trees, branches and limbs around the home. It is not designed for felling large trees or cutting large diameter logs. Use of the chain saw for operations different than intended could result in serious injury or death. - Cut wood only. For example, do not use chain saw for cutting metal, plastic or masonry. - Use this chain saw only for light-duty cutting tasks around the home and garden. - Do not use it for any other purposes. ￭ For cutting larger trees, logs or branches, a more powerful, faster saw may be necessary to reduce the risk of binding, stalling or other risks caused by a change in conditions during longer cutting times. This batteryoperated chain saw is not suitable for cutting larger trees and logs, and its use could lead to a loss of control of the object being cut and serious personal injury or death. - A battery-powered chain saw is of only limited suitability for felling and limbing. - Before starting any felling operation, fully charge your STIHL AK battery. ￭ Before starting any bucking, limbing, pruning or felling operation, ensure that all necessary cuts can be completed using the charge remaining in the STIHL AK series battery. If you are unsure: - Have multiple charged batteries available for use; - Select a more powerful chain saw; - Select a more powerful battery; or - Consult a reputable tree removal professional. ￭ Read and follow the operating and use instructions in this manual for approved applications and recommended working techniques. 0458-716-8621-E 9

6 IMPORTANT SAFETY INSTRUCTIONS

5.9

Causes and Operator Prevention of Kickback

a)Kickback may occur when the nose or tip of the guide bar

touches an object, or when the wood closes in and

pinches the saw chain in the cut.

b)Tip contact in some cases may cause a sudden reverse

reaction, kicking the guide bar up and back towards the

operator.

c) Pinching the saw chain along the top of the guide bar may

push the guide bar rapidly back towards the operator.

d)Either of these reactions may cause you to lose control of

the saw which could result in serious personal injury. Do

not rely exclusively upon the safety devices built into your

saw. As a chain saw user, you should take several steps

to keep your cutting jobs free from accident or injury.

e)Kickback is the result of chain saw misuse and/or incorrect

operating procedures or conditions and can be avoided by

taking proper precautions as given below:

Maintain a firm grip, with thumbs and fingers encircling

the chain saw handles, with both hands on the saw and

position your body and arm to allow you to resist

kickback forces.

Kickback forces can be controlled by

the operator, if proper precautions are taken. Do not let

go of the chain saw.

Do not overreach and do not cut above shoulder height.

This helps prevent unintended tip contact and enables

better control of the chain saw in unexpected situations.

Only use replacement guide bars and saw chains

specified by the manufacturer.

Incorrect replacement

guide bars and saw chains may cause chain breakage

and/or kickback.

Follow the manufacturer's sharpening and maintenance

instructions for the saw chain.

Decreasing the depth

gauge height can lead to increased kickback.

6.1

Intended Use

WARNING

￭

This chain saw is designed for cutting small diameter

trees, branches and limbs around the home. It is not

designed for felling large trees or cutting large diameter

logs. Use of the chain saw for operations different than

intended could result in serious injury or death.

–

Cut wood only. For example, do not use chain saw

for cutting metal, plastic or masonry.

–

Use this chain saw only for light-duty cutting tasks

around the home and garden.

–

Do not use it for any other purposes.

￭

For cutting larger trees, logs or branches, a more

powerful, faster saw may be necessary to reduce the risk

of binding, stalling or other risks caused by a change in

conditions during longer cutting times. This battery-

operated chain saw is not suitable for cutting larger trees

and logs, and its use could lead to a loss of control of the

object being cut and serious personal injury or death.

–

A battery-powered chain saw is of only limited

suitability for felling and limbing.

–

Before starting any felling operation, fully charge

your STIHL AK battery.

￭

Before starting any bucking, limbing, pruning or felling

operation, ensure that all necessary cuts can be

completed using the charge remaining in the

STIHL AK series battery. If you are unsure:

–

Have multiple charged batteries available for use;

–

Select a more powerful chain saw;

–

Select a more powerful battery; or

–

Consult a reputable tree removal professional.

￭

Read and follow the operating and use instructions in this

manual for approved applications and recommended

working techniques.
