top of the guide bar. The saw chain pushes the
product in the direction of the operator.
(Fig. 52)
WARNING: If the saw chain is caught in
the trunk, the product can be pushed at
you. Hold the product tightly and make
sure that the kickback zone of the guide
bar does not touch the tree and causes a
kickback.
(Fig. 53)

To use the cutting technique

WARNING: Use full throttle when you cut
and decrease to idle speed after each cut.
CAUTION: Engine damage can occur if the
engine runs for too long at full throttle
without load.
1. Put the trunk on a saw horse or runners. (Fig. 54)
WARNING: Do not cut trunks in a pile.
That increases the risk of kickback and
can result in serious injury or death.
2. Remove the cut pieces from the cutting area.
WARNING: Cut pieces in the cutting
area increase the risk of kickback and
that you can not keep your balance.
To use the spiked bumper
1. Push the spiked bumper into the trunk of the tree.
2. Apply full throttle and rotate the product. Keep the
spiked bumper against the trunk. This procedure
makes it easier to apply the force necessary to cut
through the trunk. (Fig. 55)
To cut a trunk on the ground
1. Cut through the trunk on the pull stroke. Keep full
throttle but be prepared for sudden accidents. (Fig.
56)
WARNING: Make sure that the saw
chain does not touch the ground when
you complete the kerf.
2. Cut approximately ⅔ through the trunk and then
stop. Turn the trunk and cut from the opposite side.
