CUTTING TIPS (CONT'D)
,Just as the chain completes the cut, Jet off of the throttle
and let the engine idle. Cutting should always be done
at futl throttle. Do not, however, run the engine at full
throttle out of the cut. Remember to push the oil button
every 5 to t0 seconds white cutting with model 358-
350840. Listed below are brief instructions on how to make
the most common cuts with your chain saw.
FELLING
(CUTTING DOWN A TREE)
Before felling a tree, select a safe path of retreat and clear a
wor_king area around the tree. Observe the way the tree is
leaning, if at all, and then decide where you want the tree
to fall. Trees of up to 6 or 7 inches in diameter can usually
be cut through in one pass. Under-cutting is required on
Jarger trees. See Figure 30.
To undercut, notch about 1/3 the way through the tree, on
the side you want the tree to fall. Then make the felling
cut about 2" above the notch and on the opposite side of
the felling cut, don't cut all the way through to the under-
cut. This leaves a small section of wood to act as a hinge
while the tree is falling, and allows the tree to fall in the
desired direction. If the tree is larger in diameter than the
length of the bar, the felling cut should be made from both
sides of the tree.
H
BUCKING
If you have to cut in the middle of a log which is supported
at both ends, cut halfway through the topside of the log, or
until the saw cut begins to close, see Figure 3t, then puEI
the guide bar out and undercut from the bottom side of log
using the top edge of the guide bar. See Figure 32.
