reduce the risk of severe or fatal injury from an
improperly sharpened chain.
WARNING
■ Depth gauges that are too low increase the
potential and force of kickback and other reac‐
tive forces, which can increase the risk of seri‐
ous personal injury. Always maintain the
proper distance (a) between the depth gauge
and the top of the cutter.
The depth gauge determines the depth to which
the cutter penetrates the wood and thus the chip
thickness.
A depth gauge that is too low will increase the
kickback tendency of the chain saw and can
increase kickback forces.
A depth gauge that is too high will prevent the
cutter from entering the workpiece and will lead
to poor cutting performance. Always keep the
