Kickback Safety Features; Chainsaw Names And Terms - Craftsman CMECS600 Instruction Manual

English
c ) Only use replacement bars and chains specified
by the manufacturer. Incorrect replacement
bars and chains may cause chain breakage and/
or kickback.
d ) Follow the manufacturer's sharpening and
maintenance instructions for the saw chain.
Decreasing the depth gauge height can lead to
increased kickback.
The Following Precautions Should Be
Followed to Minimize Kickback:
1 . Grip Saw Firmly. Hold the chain saw firmly with both
hands when the motor is running. Use a firm grip with
thumbs and fingers encircling the chain saw handles.
Chain saw will pull forward when cutting on the bottom
edge of the bar, and push backward when cutting along
the top edge of the bar.
2 . Do not over reach.
3 . Keep proper footing and balance at all times.
4 . Don't let the nose of the guide bar contact a log, branch,
ground or other obstruction.
5 . Don't cut above shoulder height.
6 . Use devices such as low kickback chain and reduced
kickback guide bars that reduce the risks associated
with kickback.
7 . Only use replacement bars and chains specified by the
manufacturer or the equivalent.
8 . Never let the moving chain contact any object at the tip of
the guide bar.
9 . Keep the working area free from obstructions such as
other trees, branches, rocks, fences, stumps, etc. Eliminate
or avoid any obstruction that your saw chain could hit
while you are cutting through a particular log or branch.
10 . Keep your saw chain sharp and properly tensioned. A
loose or dull chain can increase the chance of kickback.
Check tension at regular intervals with the motor stopped
and tool unplugged, never with the motor running.
11 . Begin and continue cutting only with the chain moving at
full speed. If the chain is moving at a slower speed, there is
a greater chance for kickback to occur.
12 . Cut one log at a time.
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.
14 . Do not attempt plunge cuts or bore cuts.
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 or its own cord. 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.
