WARNING
KICKBACK DANGER (Fig. 1)
One of the most severe dangers when working with a chain saw is
the possibility of kickback. Kickback may occur when the upper 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 lightning fast reverse reaction, kicking the guide bar up and
back toward you. Pinching the saw chain along the top of the guide
bar may also push the guide bar rapidly back towards you. Either of
these reactions may cause you to lose control of the saw which could
result in serious personal injury. Even though your saw has safety
built into its design, you should not rely on these safety features
exclusively. Know where your bar tip is at all times. Kickback does
occur if you allow the kickback zone (1) of the bar to touch an object.
Do not use that area. Kickback from pinching is caused by a cut
closing and pinching the upper side of the guide bar. Study your cut
and make sure it will open as you cut through. Maintain control when
the engine is running by always keeping a
fi
rm grip on the saw with
your right hand on the rear handle, your left hand on the front handle
and your thumbs and
fi
ngers encircling the handles. Always hold the
saw with both hands during operation and cut at high engine speed.
Follow manufacturer's sharpening and maintenance instructions
for the saw chain. The lack of this maintenance may increase the
possibility of kickback.
