Stihl MSE 250 C Instruction Manual page 17

To avoid pushback
1. Be alert to forces or situations that
may cause material to pinch the top
of the saw chain.
2. Do not cut more than one log at a
time.
3. Do not twist the chain saw when
withdrawing the bar from a plunge
cut or underbuck cut because the
saw chain can pinch.
WARNING
For cutting larger trees, logs or
branches, a more powerful, faster and/or
steady cut may be necessary to reduce
the risk of binding, stalling or a change in
conditions during a longer cutting time
that could lead to a loss of control of the
object being cut and serious personal
injury.
The electric chain saw is of only limited
suitability for felling and limbing.
If, however, a tree is to be felled and
limbed with a an electric chain saw, it is
imperative to observe the following
instructions.
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 contacting
the log or other limbs with the nose of the
guide bar.
MSE 250 C
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,
switch off the motor, move front hand
guard to ƒ, disconnect the plug from the
power supply 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.
Shattered wood should be cut very
carefully. Sharp slivers of wood may be
caught and flung in the direction of the
operator of the saw.
When cutting small logs, place log
through "V"-shaped supports on top of a
sawhorse. Never permit another person
to hold the log. Never hold the log with
your leg or foot.
