SMake 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.

SDo 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 and

may cause serious personal injury.

S Stop the engine before setting the saw down.

SDo not operate a chain saw that is dam- aged, improperly adjusted, or not com- pletely and securely assembled. Always replace bar, chain, hand guard, or chain

brake immediately if it becomes damaged, broken or is otherwise removed.

SWith 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 features of the chain saw and their function are explained. For inspection and maintenance, see instruc- tions in the CHECKING, MAINTAINING AND SERVICING CHAIN SAW SAFETY EQUIP- MENT 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 informa- tion, please contact your nearest service dealer.

SChain 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.

SThrottle trigger lock-out. The throttle lock--out is designed to prevent accidental operation of the throttle trigger.

SChain catcher. The chain catcher is de-

signed to catch the saw chain if it breaks.

SVibration damping system. Your chain saw is equipped with a vibration damping system that is designed to minimize vibra- tion 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 peo- ple prone to circulation disorders or abnormal swellings. Prolonged use in cold weather has been linked to blood vessel damage in other- wise healthy people. If symptoms occur such as numbness, pain, loss of strength, change in skin color or texture, or loss of feeling in the fin- gers, hands, or joints, discontinue the use of this tool and seek medical attention. An anti- vibration system does not guarantee the avoid-

ance 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.

SON/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 main- tained. If your chain saw does not pass in- spection, take the saw to your nearest ser- vice dealer for repair.

S Chain brake. Brush off any wood dust, resin and dirt from the chain brake and clutch drum. Dirt and wear can impair op- eration of the brake. For additional infor- mation, see OPERATING YOUR UNIT section.

SThrottle 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 at- tached 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 at- tached 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

SHave 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 fly- wheel to burst.

SMake certain the saw chain stops moving when the throttle trigger is released. For correction, refer to CARBURETOR AD-

JUSTMENTS.

SNever modify your saw in any way. Use

only attachments supplied or specifically recommended by the manufacturer.

SKeep the handles dry, clean, and free of oil

or fuel mixture.

SKeep 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

SDo not smoke while handling fuel or while operating the saw.

SEliminate 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 en- gine to cool before refueling.
