13 . Use extreme caution when re‑entering a previous
cut. Engage ribbed bumpers into wood and allow chain to
reach full speed before proceeding with cut.

15 . Watch for shifting logs or other forces that could
close a cut and pinch or fall into chain.
Kickback Safety Features
WARNING: The following features are included
on your saw to help reduce the hazard of kickback;
however such features will not totally eliminate this
dangerous reaction. As a chain saw user do not rely
only on safety devices. You must follow all safety
precautions, instructions, and maintenance in this
manual to help avoid kickback and other forces which
can result in serious injury.
•
Reduced‑Kickback Guide Bar, designed with a small radius
tip which reduces the size of the kickback danger zone on
bar tip. A reduced ‑ kickback guide bar is one which has
been demonstrated to significantly reduce the number and
seriousness of kickbacks when tested in accordance with
safety requirements for electric chain saws.
•
Low‑Kickback Chain, designed with a contoured depth
gauge and guard link which deflect kickback force
and allow wood to gradually ride into the cutter. A
low‑kickback chain is a chain which has met kickback
performance requirements of ANSI B175.1–2012.
•
Do not operate chain saw while in a tree, on a ladder, on a
scaffold, or from any unstable surface.
•
Hold tool by insulated gripping surfaces when performing
an operation where the cutting tool may contact hidden
wiring. Contact with a "live" wire will make exposed metal
parts of the tool "live" and shock the operator.
•
Do not attempt operations beyond your capacity or
experience. Read thoroughly and understand completely all
instructions in this manual.
•
Before you start chain saw, make sure saw chain is not
contacting any object.
•
Do not operate a chain saw with one hand! Serious injury
to the operator, helpers, or bystanders may result from one‑
handed operation. A chain saw is intended for two‑handed
use only.
•
Keep the handles dry, clean, and free of oil or grease.
•
Do not allow dirt, debris, or sawdust to build up on the
motor or outside air vents.
•
Stop the chain saw before setting it down.
•
Do not cut vines and/or small under brush.
•
Use extreme caution when cutting small size brush and
saplings because slender material may catch the saw chain
and be whipped toward you or pull you off balance.

•
into lengths.
Motor Brake (if equipped) ‑ A device used to stop the

Chain Saw Powerhead ‑ A chain saw without the saw
•
chain and guide bar.
Drive Sprocket or Sprocket ‑ The toothed part that drives
•
the saw chain.
Felling ‑ The process of cutting down a tree.
•
Felling Back Cut ‑ The final cut in a tree felling operation
•
made on the opposite side of the tree from the notching cut.
Front Handle ‑ The support handle located at or toward
•
the front of the chain saw.
Front Hand Guard ‑ 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.
Guide Bar ‑ A solid railed structure that supports and
•
guides the saw chain.
Scabbard/Guide Bar Cover ‑ Enclosure fitted over guide
•
bar to help prevent tooth contact when saw is not in use.
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 closes in and pinches
the saw chain in the cut.
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.
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.
Limbing ‑ Removing the branches from a fallen tree.
•
Low‑Kickback Chain ‑ A chain that complies with the
•
kickback performance requirements of ANSI B175.1–2012
(when tested on a representative sample of chain saws).
Normal Cutting Position ‑ Those positions assumed in
•
performing the bucking and felling cuts.
Notching Undercut ‑ A notch cut in a tree that directs the
•
tree's fall.
Rear Handle ‑ The support handle located at or toward
•
the rear of the saw.
Reduced Kickback Guide Bar ‑ A guide bar which has
•
been demonstrated to reduce kickback significantly.
Replacement Saw Chain ‑ A chain that complies with
•
kickback performance requirements of ANSI B175.1–2012
when tested with specific chain saws. It may not meet
the ANSI performance requirements when used with
other saws.
Saw Chain ‑ A loop of chain having cutting teeth, that cut
•
the wood, and that is driven by the motor and is supported
by the guide bar.
Ribbed Bumper ‑ The ribs used when felling or bucking to
