station, local authority centre or where facilities
exist.
9. Do store fuel in an approved container
designed for that purpose.
10. Do ensure that the product is cleaned and
that a complete service is conducted before any
long-term storage.
Causes and operator prevention of kickback
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.
Tip contact in some cases may cause a sudden
reverse reaction, kicking the guide bar up and
back towards the operator.
Pinching the saw chain along the top of the
guide bar may push the guide bar rapidly back
towards the operator.
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

19
cutting jobs free from accident or injury.
Kickback is the result of tool misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below:
1. Maintain a rm grip, with thumbs and
ngers 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 bars and chains
specied by the manufacturer. Incorrect
replacement bars and 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.
Vibration and noise reduction
To reduce the impact of noise and vibration
emission, limit the time of operation, use low-
vibration and low-noise operating modes as well
as wear personal protective equipment.
