closes. Tip contact in some cases may cause a
lightning fast reverse reaction, kicking the guide
bar up and back towards the operator.
4.7.2 Pinching the chainsaw 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 chainsaw which
could result in serious personal injury.
4.7.3. Do not rely exclusively on the safety devices
built into your saw. As a chainsaw user you should
take several steps to keep cutting jobs free from
accident or injury.
4.7.4. With basic understanding of kickback you
can reduce or eliminate the element of surprise.
4.7.5. Keep good grip on the saw with both hands,
the right hand on the rear handle, and the left on
the front handle when the engine is running. Use
a firm grip with thumbs and fingers encircling the
chainsaw handles. A firm grip will help you reduce
kickback and maintain control of the saw.
4.7.6. Make certain that the area in which you are
cutting is free from obstructions. Do not let the
nose of the guide bar contact the log, branch or
any other obstruction which could be hit while you
are operating the saw.
4.7.7. Cut at high engine speeds.
4.7.8. Do not overreach or cut above shoulder
height.
4.7.9. Follow manufacturers sharpening and main-
tenance instructions for saw chains.
4.7.10. Only use replacement bars and chains
specified.
