S Keep all parts of your body away from the
chain when the engine is running.
S Keep children, bystanders, and animals a
minimum of 10 Meters away from the work
area. Do not allow other people or animals
to be near the chain saw when starting or
operating the chain saw.
S Do not handle or operate a chain saw when
you are fatigued, ill, or upset, or if you have
taken alcohol, drugs, or medication. Y ou
must be in good physical condition and mentally alert. Chain saw work is strenuous. If
you have any condition that might be aggravated by strenuous work, check with your
doctor before operating a chain saw.
S Carefully plan your sawing operation in ad-
vance. Donot start cutting until you have a
clear work area, secure footing, and, if you
are felling trees, a planned retreat path.
OPERATE YOUR SAW SAFELY
WARNING: Long term inhalation of
the engine’s exhaust fumes, chain oil mist and
dust from sawdust can result in serious personal injury.
S Do not operate a chain saw with one hand.
Serious injury to the operator, helpers, bystanders or any combination of these persons may result from one-handed operation.
A chain saw is intended for two-handed use.
S Operate the chain saw only in a well-venti-
lated outdoor area.
S Do not operate saw from a ladder or in a tree,
unless you are specifically trained to do so.
S Make sure the chain will not make contact
with any object while starting the engine.
Never try to start the saw when the guide
bar is in a cut.
3
S Do not put pressure on the saw at the end of
the cut. Applying pressure can cause you to
lose control when the cut is completed.
S Stop the engine before setting the saw
down.
S Do not operate a chain saw that is dam-
aged, improperly adjusted, or not completely and securely assembled. Always
replace bar, chain, hand guard, or chain
brake immediately if it becomes damaged,
broken or is otherwise removed.
S With the engine stopped, hand carry the
chain saw with the muffler away from your
body, and the guide bar and chain to the
rear, preferably covered with a scabbard.
CHAIN SAW SAFETY EQUIPMENT
NOTE:
In this section, the safety feature s of
the chain saw and their function are explained.
For inspection and maintenance, see instructions in the CHECKING, MAINTAINING AND
SERVICING CHAIN SAW SAFETY EQUIPMENT section. See instructions under the
WHAT IS WHAT? section, to find where these
parts are located on your chain saw. The life
span of the machine can be reduced and the
risk of accidents can increase if machine maintenance is not carried out correctly and if service and/or repairs are not carried out professionally. If you need further information, please
contact your nearest service dealer.
S Chain brake. Y our chain saw is equipped
with a chain brake that is designed to stop
the chain from moving.
WARNING: The chain brake is de-
signed to stop the chain immediately if you
get a kickback. The chain brake reduces the
risk of accidents, but only you can prevent
them.DO NOT ASSUME THATTHE CHAIN
BRAKE WILL PROTECT YO U IN THE
EVENT OF A KICKBACK.
S Throttle trigger lock -- out. The thro ttle
lock--out is designed to prevent accidental
operation of the throttle trigger.
S Chain catcher. The chain catcher is de-
signed to catch the saw chain if it breaks.
S Vibration damping system. Your chain
saw is equipped with a vibration damping
systemthat is designed to minimize vibration and make operation easier.
SAFETY NOTICE: Exposure to vibrations
through prolonged use of gasoline powered
hand tools could cause blood vessel or nerve
damage in the fingers, hands, and joints of people prone to circulation disorders or abnormal
swellings. Prolonged use in cold weather has
been linked to blood vessel damage in otherwise healthy people. If symptoms occur such
as numbness, pain, loss of strength, change in
skin color or texture, or loss of feeling in the fingers, hands, or joints, discontinue the use of
this tool and seek medical attention. An antivibration system does not guarantee the avoidance of these problems. Users who operate
power tools on a continual and regular basis
must monitor closely their physical condition
and the condition of this tool.
S ON/STOP switch. The ON/STOP switch
should be used to stop the engine.
CHECKING, MAINTAINING AND
SERVICING CHAIN SAW SAFETY
EQUIPMENT
WARNING: Never use a chain saw
with defective safety equipment. Safety
equipment must be inspected and maintained. If your chain saw does not pass inspection, take the saw to your nearest service dealer for repair.
S Chain brake. Brush off any wood dust, res-
in and dirt from the chain brake and clutch
drum. Dirt and wear can impair operation of
the brake. For additional information, see
OPERATING YOUR UNIT section.
S Throttle trigger lock-- out. Check that the
throttle trigger can not be operated until the
throttle lock--out is pressed.
S Chain catcher. Check that the chain
catcher is not damaged and is firmly attached to the body of the chain saw.
S Vibration damping system. Regularly
check the vibration damping units for
cracks or deformation. Make sure the
vibration damping units are securely attached to the engine unit and handle unit.
S ON/STOP switch. Start the engine and
make sure the engine stops when you
move the ON/STOP switch to the STOP
position.
MAINTAIN YOUR SAW IN GOOD
WORKING ORDER
S Have all chain saw service performed by a
qualified service dealer with the exception of
the items listed in the maintenance section of
this manual. For example, if improper tools
are used to remove or hold the flywheel
when servicing the clutch, structural damage
to the flywheel can occur and cause the flywheel to burst.
S Make certain the saw chain stops moving
when the throttle trigger is released. For
correction, refer to CARBURETOR ADJUSTMENTS.
S Never modify your saw in any way. Use
only attachments supplied or specifically
recommended by the manufacturer.
S Keep the handles dry, clean, and free of oil
or fuel mixture.
S Keep fuel and oil caps, screws, and fas-
teners securely tightened.
S Use only McCulloch accessories and re-
placement parts as recommended.
HANDLE FUEL WITH CAUTION
S Do not smoke while handling fuel or while
operating the saw.
S Eliminate all sources of sparks or flame in
the areas where fuel is mixed or poured.
There should be no smoking, open flames,
or work that could cause sparks. Allow engine to cool before refueling.
S Mix and pour fuel in an outdoor area on bare
ground; store fuel in a cool, dry, well ventilated place; and use an approved, marked
container for all fuel purposes. Wipe up all
fuel spills before starting saw.
S Move at least 10 feet (3 meters) from fuel-
ing site before starting engine.
4
S Turn the engine off and let saw cool in a
non-combustible area, not on dry leaves,
straw, paper, etc. Slowly remove fuel cap
and refuel unit.
S Store the unit and fuel in an area where fuel
vapors cannot reach sparks or open
flames from water heaters, electric motors
or switches, furnaces, etc.
KICKBACK
WARNING: Avoid kickback which
can result in serious injury. Kickback is the
backward, upward or sudden forward motion
of the guide bar occurring when the saw
chain near the upper tip 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. Contacting a foreignobject in the wood can also result in loss of
chain saw control.
S Rotational Kickback can occur when the
moving chain contacts an object at the upper tip of the guide bar. This contact can
cause the chain to dig into the object,
which stops the chain for an instant. The
result is a lightning fast, reverse reaction
which kicks the guide bar up and back toward the operator.
S Pinch-Kickback can occur when the the
wood closes in and pinches the moving
saw chain in the cut along the top of the
guide bar and the saw chain is suddenly
stopped. This sudden stopping of the
chain results in a reversal of the chain
force used to cut wood and causes the
saw tomove in the opposite direction of the
chain rotation. The saw is driven straight
back toward the operator.
S Pull-In can occur when the moving chain
contacts a foreign object in the wood in the
cut along the bottom of the guide bar and the
saw chain is suddenly stopped. This sudden
stopping pulls the saw forward and away
from the operator and could easily cause the
operator to lose control of the saw.
Avoid Pinch--Kickback:
S Be extremely aware of situations or obstruc-
tions that can cause material to pinch the top
of or otherwise stop the chain.
S Do not cut more than one log at a time.
S Do not twist the saw as the bar is with-
drawn from an undercut when bucking.
Avoid Pull -- In:
S Always begin cutting with the engine at full
speed and the saw housing against wood.
S Use wedges made of plastic or wood.
Never use metal to hold the cut open.
Avoid obstructions
Clear the
working area
REDUCETHECHANCEOF
KICKBACK
S Recognize that kickback can happen.
With a basic understanding of kickback,
you can reduce the element of surprise
which contributes to accidents.
S Never let themoving chain contact any ob-
ject at the tip of the guide bar.
S Keep the working area free from obstruc-
tions 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.
S Keep your saw chain sharp and properly
tensioned. A loose or dull chain can increase
the chance of kickback occurring. Follow
manufacturer’s chain sharpening and maintenance instructions. Check tension at regular intervals with the engine stopped, never
with the engine running. Make sure the bar
clamp nuts are securely tightened after tensioning the chain.
S Begin and continue cutting at full speed. If
the chain is moving at a slower speed, there
is greater chance of kickback occurring.
S Cut one log at a time.
S Use extreme caution when re-entering a
previous cut.
S Do not attempt cuts starting with the tip of
the bar (plunge cuts).
S Watch for shifting logs or other forces that
could close a cut and pinch or fall into chain.
S Use the Reduced--Kickback Guide Bar and
Low- -Kickback Chain specified for your saw.
