English WARNING Use extreme caution when cutting small size brush and saplings which may easily catch the saw chain, be whipped towards you or pull you off balance. To avoid pull-in 1. Always start a cut with the saw chain rotating at full speed and the bumper spike in contact with the wood. 2. The risk of pull-in may also be reduced by using wedges to open the kerf or cut. B = Pushback B Pushback occurs when the saw chain on the top of the bar is suddenly stopped when it is pinched, caught or encounters a foreign object in the wood. The reaction of the saw chain may drive the chain saw rapidly straight back toward the operator and may cause loss of chain saw control, which, in turn, may cause serious or fatal injury. Pushback frequently occurs when the top of the bar is used for cutting. 001BA038 KN 001BA033 KN 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. 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, remove the battery 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. 16 MSA 160 C, MSA 200 C

WARNING
Use extreme caution when cutting small
size brush and saplings which may
easily catch the saw chain, be whipped
towards you or pull you off balance.
To avoid pull-in
1.
Always start a cut with the saw
chain rotating at full speed and the
bumper spike in contact with the
wood.
2.
The risk of pull-in may also be
reduced by using wedges to open
the kerf or cut.
B = Pushback
Pushback occurs when the saw chain on
the top of the bar is suddenly stopped
when it is pinched, caught or encounters
a foreign object in the wood. The
reaction of the saw chain may drive the
chain saw rapidly straight back toward
the operator and may cause loss of
chain saw control, which, in turn, may
cause serious or fatal injury. Pushback
frequently occurs when the top of the bar
is used for cutting.
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.
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
, remove the battery 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.
