Stihl MS 460 Instruction Manual page 23

The plunge cut is made with the guide
bar nose. Begin the plunge cut by
applying the lower portion of the guide
bar nose to the tree at an angle. Cut until
the depth of the kerf is about the same
as the width of the guide bar. Next, align
the saw in the direction in which the
recess is to be cut.
With the saw at full throttle, insert the
guide bar in the trunk.
Enlarge the plunge cut as shown in the
illustration.
Warning!
There is an extreme danger of kickback
at this point. Extra caution must be
taken to maintain control of the saw. To
make the felling cut, follow the section-
ing method described previously.
If you are inexperienced with a chain
saw, plunge-cutting should not be
attempted. Seek the help of a
professional.

Warning!
In order to reduce the risk of personal
injury, never stand directly behind the
tree when it is about to fall, since part of
the trunk may split and come back
towards the operator (barber-chairing),
or the tree may jump backwards off the
stump. Always keep to the side of the
falling tree. When the tree starts to fall,
withdraw the bar, shut off the engine
and walk away on the preplanned
escape path. Watch out for falling limbs.
Warning!
Be extremely careful with partially fallen
trees which are poorly supported. When
the tree hangs or for some other reason
does not fall completely, set the saw
aside and pull the tree down with a
cable winch, block and tackle or tractor.
If you try to cut it down with your saw,
you may be injured.
Limbing
Limbing is removing the branches from a
fallen tree.
Warning!
There is an extreme danger of kickback
during the limbing operation. Do not
work with the nose of the bar. Be
extremely cautious and avoid contact-
ing the log or other limbs with the nose
of the guide bar.
Do not stand on a log while limbing it –
you may slip or the log may roll.
Start limbing by leaving the lower limbs
to support the log off the ground. When
underbucking freely hanging limbs, a
pinch may result or the limb may fall,
causing loss of control. If a pinch occurs,
stop the engine and remove the saw by
lifting the limb.
Warning!
Be extremely cautious when cutting
limbs or logs under tension (spring
poles). The limbs or logs could spring
back toward the operator and cause
loss of control of the saw and severe or
fatal injury to the operator.
Bucking
Bucking is cutting a log into sections.
Warning!
When bucking, do not stand on the log.
Make sure the log will not roll downhill. If
on a slope, stand on the uphill side of
the log. Watch out for rolling logs.
Cut only one log at a time.
