GENERAL SAFETY PRECAUTIONS
S Chain brake. Your 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 THAT THE CHAIN BRAKE
WILL PROTECT YOU IN THE EVENT OF A
KICKBACK.
S Throttle trigger lock--out. The throttle
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. Y our 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 SA W
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 triggerlock--out. Check thatthe
throttle trigger cannot beoperated 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 beno smoking, openflames,
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.
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 Storethe unitand fuel in anarea wherefuel
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 orsudden forward motion
of the guide bar occurring when the saw
chain near theupper tip of the guidebar contacts any object such as a log or branch, or
when the wood closes in and pinches the
saw chain in the cut. Contacting aforeign object in the wood can also result in loss of
chain saw control.
S Rotational Kickback can occ ur whenthe
moving chain contacts an object at theupper tip of the guide bar. This contact can
cause the chain to dig into the object,
