Hold the chainsaw firmly with both hands and maintain a secure grip. 2. Be aware of the location of the guide bar nose at all times. 3. Never let the nose of the guide bar contact any object. Do not cut limbs with the nose of the guide bar. Be especially careful when cutting small, tough limbs, small size brush and saplings which may easily catch the chain. 4 Don't overreach. 5. Don't cut above shoulder height. 6. Begin cutting and continue at full throttle. 7. Cut only one log at a time. 8. Use extreme caution when reentering a previous cut. 9. Do not attempt to plunge cut if you are not experienced with this cutting technique. 10. Be alert for shifting of the log or other forces that may cause the cut to close and pinch the chain. 11. Maintain saw chain properly. Cut with a correctly sharpened, properly tensioned chain at all times. 12. Stand to the side of the cutting path of the chainsaw. A A = Pull-in: Pull-in occurs when the chain on the bottom of the bar is suddenly stopped when it is pinched, caught or encounters a foreign object in the wood. The reaction of the chain pulls the saw forward and may cause the operator to lose control. Pull-in frequently occurs when the bumper spike of the saw is not held securely against the tree or limb and when the chain is not rotating at full speed before it contacts the wood. !Warning! Use extreme caution when cutting small size brush and saplings which may easily catch the chain and pull you off balance. To avoid pull-in 1. Always start a cut with the chain rotating at full speed and the bumper spike in contact with the wood. 2. Pull-in may also be prevented by using wedges to open the kerf or cut. B B = Pushback: Pushback occurs when the 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 chain drives the saw straight back toward the operator and may cause loss of saw control. 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 chain. 2. Do not cut more than one log at a time. 3. Do not twist the saw when withdrawing the bar from a plunge cut or underbuck cut because the chain can pinch. 16 MSE 140 C, MSE 160 C, MSE 180 C, MSE 200 C

that may result from kickback is to avoid
kickback situations:
1.
Hold the chainsaw firmly with both
hands and maintain a secure grip.
2.
Be aware of the location of the guide
bar nose at all times.
3.
Never let the nose of the guide bar
contact any object. Do not cut limbs
with the nose of the guide bar. Be
especially careful when cutting
small, tough limbs, small size brush
and saplings which may easily catch
the chain.
4
Don't overreach.
5.
Don't cut above shoulder height.
6.
Begin cutting and continue at full
throttle.
7.
Cut only one log at a time.
8.
Use extreme caution when
reentering a previous cut.
9.
Do not attempt to plunge cut if you
are not experienced with this cutting
technique.
10.
Be alert for shifting of the log or
other
forces that may cause the cut
to close and pinch the chain.
11.
Maintain saw chain properly. Cut
with a correctly sharpened, properly
tensioned chain at all times.

of the chainsaw.
A = Pull-in:
Pull-in occurs when the chain on the
bottom of the bar is suddenly stopped
when it is pinched, caught or encounters
a foreign object in the wood. The
reaction of the chain pulls the saw
forward and may cause the operator to
lose control.
Pull-in frequently occurs when the
bumper spike of the saw is not held
securely against the tree or limb and
when the chain is not rotating at full
speed before it contacts the wood.
!
Warning!
Use extreme caution when cutting small
size brush and saplings which may
easily catch the chain and pull you off
balance.
To avoid pull-in
1.
Always start a cut with the chain
rotating at full speed and the
bumper spike in contact with the
wood.
2.
Pull-in may also be prevented by
using
wedges to open the kerf or
cut.
B = Pushback:
Pushback occurs when the 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 chain drives the saw straight back
toward the operator and may cause loss
of saw control. 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 chain.
2.
Do not cut more than one log at a
time.
3.
Do not twist the saw when
withdrawing the bar from a plunge
cut or underbuck cut because the
chain can pinch.
