• 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
pivot the saw and maintain position while sawing.
• Switch ‑ A device that when operated will complete or interrupt
an electrical power circuit to the motor of the chain saw.
• Switch Linkage ‑ The mechanism that transmits motion
from a trigger to the switch.
• Switch Lockout ‑ A movable stop that prevents the
unintentional operation of the switch until manually actuated.
Additional Safety Information
WARNING: Never modify the power tool or any part of it.
Damage or personal injury could result.
WARNING: ALWAYS use safety glasses. Everyday
eyeglasses are NOT safety glasses. Also use face or dust
mask if operation is dusty. ALWAYS WEAR CERTIFIED
SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.
WARNING: Some dust contains chemicals known to
State of California to cause cancer, birth defects or other
reproductive harm. Some examples of these chemicals are:
• compounds in fertilizers,
• compounds in insecticides, herbicides and pesticides,
• arsenic and chromium from chemically treated lumber.
To reduce your exposure to these chemicals, wear approved
safety equipment such as dust masks that are specially
designed to filter out microscopic particles.
• Avoid prolonged contact with dust from power sanding,
sawing, grinding, drilling, and other construction activities.
Wear protective clothing and wash exposed areas with
soap and water. Allowing dust to get into your mouth, eyes, or
lie on the skin may promote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or
disperse dust, which may cause serious and permanent
respiratory or other injury. Always use NIOSH/OSHA
approved respiratory protection.
WARNING: Always wear proper personal hearing
protection that conforms to ANSI S12.6 (S3.19) during
use. Under some conditions and duration of use, noise from
this product may contribute to hearing loss.
CAUTION: When not in use, place tool on its side
on a stable surface where it will not cause a tripping
or falling hazard. Some tools with a large battery pack will
stand upright but may be easily knocked over.
• Air vents often cover moving parts and should be avoided.
Loose clothes, jewelry or long hair can be caught in moving parts.
• The maximum speed of the saw chain is less
than 20 m/s
