English Low kickback chain will not significantly reduce the risk of kickback injury when used on a bow guide. To Avoid Kickback The best protection from personal injury that may result from kickback is to avoid kickback situations: 1. Hold the chain saw firmly with both hands and maintain a secure grip. Don't let go. 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 near wire fences and 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 these cutting techniques. 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 chain saw. A = Pull-in A 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, be whipped towards you or 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. The risk of pull-in may also be reduced by using wedges to open the kerf or cut. 001BA037 KN 001BA038 KN B = Pushback B 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 may drive the saw rapidly 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. 4. Do not underbuck freely hanging limbs because the chain may get pinched and cause pushback and loss of control. WARNING This chain saw equipped with a top handle is designed specifically for tree surgery and maintenance. Due to the 16 MS 150 TC

Low kickback chain will not significantly
reduce the risk of kickback injury when
used on a bow guide.
To Avoid Kickback
The best protection from personal injury
that may result from kickback is to avoid
kickback situations:
1.
Hold the chain saw firmly with both
hands and maintain a secure grip.
Don’t let go.
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 near wire fences
and 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 these
cutting techniques.
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 chain saw.
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, be whipped
towards you or 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.
The risk of pull-in may also be
reduced 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 may drive the saw rapidly
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.
4.
Do not underbuck freely hanging
limbs because the chain may get
pinched and cause pushback and
loss of control.
