straw, paper, etc. Slowly remove fuel cap and refuel unit.
SStore the unit and fuel in an area where fuel vapors cannot reach sparks or open flames from water heaters, electric motors or switches, furnaces, etc.
KICKBACK
WARNING: Avoid kickback which can result in serious injury. Kickback is the backward, upward or sudden forward motion of the guide bar occurring when the saw chain near the upper tip of the guide bar con- tacts any object such as a log or branch, or when the wood closes in and pinches the saw chain in the cut. Contacting a foreign ob- ject in the wood can also result in loss of chain saw control.
SRotational Kickback can occur when the moving chain contacts an object at the up- per tip of the guide bar. This contact can cause the chain to dig into the object, which stops the chain for an instant. The result is a lightning fast, reverse reaction which kicks the guide bar up and back to- ward the operator.

Avoid Pinch-Kickback:
SBe extremely aware of situations or obstruc-
tions that can cause material to pinch the top of or otherwise stop the chain.
SDo not cut more than one log at a time.
SDo not twist the saw as the bar is with- drawn from an undercut when bucking.
Avoid Pull-In:
SAlways begin cutting with the engine at full speed and the saw housing against wood.
S Use wedges made of plastic or wood. Never use metal to hold the cut open.

Clear the working area
REDUCE THE CHANCE OF
KICKBACK
S Recognize that kickback can happen. With a basic understanding of kickback, you can reduce the element of surprise which contributes to accidents.
SNever let the moving chain contact any ob- ject at the tip of the guide bar.
SKeep the working area free from obstruc- tions such as other trees, branches, rocks, fences, stumps, etc. Eliminate or avoid any obstruction that your saw chain could hit while you are cutting through a particular log
or branch.
S Keep your saw chain sharp and properly tensioned. A loose or dull chain can increase the chance of kickback occurring. Follow manufacturer’s chain sharpening and main- tenance instructions. Check tension at regu- lar intervals with the engine stopped, never with the engine running. Make sure the bar clamp nuts are securely tightened after ten- sioning the chain.
SBegin and continue cutting at full speed. If
the chain is moving at a slower speed, there is greater chance of kickback occurring.
SCut one log at a time.
SUse extreme caution when
previous cut.
SDo not attempt cuts starting with the tip of the bar (plunge cuts).
SWatch for shifting logs or other forces that
could close a cut and pinch or fall into chain.
