wARNING: When using an electric
chain saw, basic safety precautions
should always be followed to reduce the risk
of fire, electric shock, and injury to persons,
including the following:
1. CAUTION! Do not use a replacement saw
chain unless:
a) It has been designated as meeting
the ANSI B175 kickback performance
requirements on that specific power head;
b) It has been designated as "low- Kickback"
saw chain in accordance with ANSI B175.1;
or
c) It is the saw manufacturer's replacement
catalogue (or equivalent) number.
low-Kickback saw chain is a chain which has
met the kickback performance requirements
of ANSI B175.1 when tested on the
representative sample of chain saws.
2. Use the extension cord to be a type
acceptable for outdoor use, for example –
SJTW, and the size should be 14AWG or
larger. An undersized cord will cause a drop
in line voltage resulting in loss of power and
overheating. Make sure the extension cord
is in good condition before using; and keep
the cord away from the cutting area and to
position cord so that it will not be caught on
branches, and the like, during cutting.
3. NOMENClATUER (See Fig A1)
a) Bucking – The process of cross cutting a
felled tree or log into lengths.
b) Chain Brake – A device used to stop the
chain saw.
c) Chain saw power head – A chain saw
without the saw chain and guide bar.
d) Clutch – A mechanism for connecting and
disconnecting a driven member to and
from a rotating source of power.
e) Drive Sprocket or Sprocket – The toothed
part that drives the saw chain.
f) Felling – The process of cutting down a
Electric chain saw
tree.
g) Felling Back Cut – The final cut in a tree
felling operation made on the opposite
side of the tree from the notching
undercut.
h) Front Handle (6)– The support handle
located at or toward the front of the chain
saw.
i) Hand guard (5)– A structural barrier
between the front handle of a chain saw
and the guide bar, typically located close
to the hand position on the front handle
and sometimes employed as an activating
lever for a chain brake.
j) Chain bar(7) – A solid railed structure that
supports and guides the saw chain.
k) Kickback – The backward or upward
motion, or both of the guide bar occurring
when the saw chain near the nose of the
top area of the guide bar contacts any
object such as a log or branch, or when the
wood closed in the pinches the saw chain
in the cut.
l) Kickback, Pinch – The rapid pushback of
the saw which can occur when the wood
closes in and pinches the moving saw
chain in the cut along the top of the guide
bar.
m) Kickback, Rotational – The rapid upward
and backward motion of the saw which can
occur when the moving saw chain near the
upper portion of the tip of the guide bar
contacts an object, such as a log or branch.
n) low-Kickback Chain – A chain that
complies with the kickback performance
requirements of ANSI B175.1-1991 when
tested on a representative sample of chain
saws.
o) Normal Cutting Position – Those positions
assumed in performing the bucking and
felling cuts.
p) Notching Undercut – A notch cut in a tree
that directs the tree's fall.
q) Oiler Control – A system for oiling the
guide bar and saw chain.
r) Rear Handle (1)– The support handle
located at or toward the rear of the saw.
s) Reduced Kickback Guide Bar – A guide bar
which has been demonstrated to reduce
kickback significantly.
