Page 7: Kickback Safety Precautions
2. Kickback safety precautions DANGER Kickback safety precaution for chain saw users: 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. In some cases, tip contact may cause a lightning-fast reverse reaction, kicking the guide bar up and back toward the operator (this is called a rotational kickback). -
Page 8: Other Safety Precautions
It is believed that a condition called Raynaud's Phenomenon, which affects the fingers of certain individuals, may be brought about by exposure to cold and vibration. Accordingly, your ECHO chain saw has shock mounts designed to reduce the intensity of vibration received through the handles. - Page 9 WARNING Do not modify a chain saw in any way. Only attachments and parts supplied by ECHO or expressly approved by ECHO for use with the specific ECHO chain saw models are authorized. Although certain unauthorized attachments are useable with the ECHO powerhead, their use may, in fact, be extremely dangerous.
