tree from twisting and falling in the wrong direction. Do
not cut through the hinge.
As the felling cut gets close to the hinge the tree should
begin to fall. If there is any chance that the tree may not
fall in the desired direction or it may rock back and bind
the saw chain, stop cutting before the felling back cut is
complete and use wedges of wood, plastic or aluminium
to open the cut and drop the tree along the desired line
of fall.
When the tree begins to fall remove the chain saw from
the cut, stop the motor, put the chain saw down, then use
the retreat path planned. Be alert for overhead limbs fall-
ing and watch your footing.
d) Limbing a Tree
Limbing is removing the branches from a fallen tree.
When limbing, leave larger lower limbs to support the log
off the ground. Remove the small limbs in one cut as il-
lustrated in Figure 11. Branches under tension should be
cut from the bottom up to avoid binding the chain saw.
e) Bucking a Log
Bucking is cutting a log into lengths. It is important to
make sure your footing is fim and your weigth is evenly
distributed on both feet. When possible, the log should
be raised and supported by the use of limbs, logs or
chocks. Follow the simple directions for easy cutting.
When the log is supported along its entire length as il-
lustrated in Figure 12, it is cut from the top (over-buck).
When the log is supported on one end, as illustrated in
Figure 13, cut 1/3 the diameter from the underside (un-
derbuck). Then make the finished cut by overbucking to
meet the first cut.
When the log is supported on both ends, as illustrated
in Figure 14, cut 1/3 of that diameter from the top over-
bruck. Then make the finished cut by underbucking to
meet the first cut.
When bucking on a slope always stand on the uphill
side of the log, as illustrated in Figure 15. When "cutting
through", to maintain complete control release the cutting
pressure near the end of the cut without relaxing your
grip on the chain saw handles. Don't let the chain con-
tact the ground. After completing the cut, wait for the saw
chain to stop before you move the chain saw. Always
stop the motor before moving from tree to tree.
f) Spiked bumper (Fig. 16)
• Dig the spiked bumper into the log and use it as a
pivot. Cut with an arched motion to make the bar pen-
etrate the wood.
• Repeat several times if necessary, changing the point
where you plant the spiked bumper.
9. Maintenance and Servicing
Always withdraw the plug when carrying out
maintenance and servicing.
• Always remove wood shavings and oil from your chain
saw after use. Ensure in particular that the motor ven-
