changing accessories. Improperly tensioned or lubricated
chain may either break or increase the chance for
kickback.
• Keep handles dry, clean, and free from oil and grease.
Greasy, oily handles are slippery causing loss of control.
• Cut wood only. Do not use chain saw for purposes not
intended. For example: do not use chain saw for cutting
plastic, masonry or non-wood building materials. Use of
the chain saw for operations different than intended could
result in a hazardous situation.
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
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:
• 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. (Fig.1) 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 bars and chains specified by the
manufacturer. Incorrect replacement bars and 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.
• The first time user should request an experienced operator
in the use of the chainsaw and the protective equipment,
and should be have the initial practice cutting logs on a
saw horse or cradle.
• This appliance is not intended for use by persons (including
children) with reduced physical, sensory or mental
