Please read the operator's manual carefully and make sure you understand the instructions before using the machine.

ThankyouforchoosingaMcCullochproduct.Youaretherebypartofastorythatstartedlong ago,when the McCulloch Corporation started its manufacturing of engines during World War II. In 1949, when McCulloch introduced its first light one-man chain saw, woodworking would never be thesame again.

The line of innovative chain saws would continue over the decades, and business was expanded, first by airplane and kart engines in the 1950s, then by mini chainsaws in the 1960s. Later, in the 1970sand80s,trimmersand blower/vacswereaddedtothe range.

Today, as a part of the Husqvarna group, McCulloch continues the tradition of powerful engines, technical innovations, and strong designs that have been our hallmarks for more than half a century. Lowering fuel consumption, emissions and noise levels are of top priority to us, as is improving safety and user-friendliness.

We certainly hope that you will be satisfied with your McCulloch product, as it is designed to be your companion for a long time. By following this operators manual's advice on usage, service, and maintenance, its lifespan can be extended. If you should need professional help with repair or service, please use the Service Locator at www.mcculloch.com.

CHECKING, MAINTAINING AND SERVICING CHAIN SAW SAFETY EQUIPMENT

WARNING: Never use each chainsaw defective safety equipment. Safety equipment must be inspected and maintained. If your chainsaw does not pass-inction, takes the purpose to your nearest dealer for repair.

• Chainbrake.Brushoffanywooddust,resinanddirtfromthechainbrakeandclutchdrum.Dirtandwearcanimpairoperationofthebrake.For additional information,see OPERATINGYOURUNITsection.
• Throttletriggerlock--out. Check that the throttle trigger can not be operated until the throttlelock--out is pressed.
• Chain catcher. Check that the chain catcher is not damaged and is firmly attached to the body of the chainsaw.
• Vibration damping system. Regularly check the vibration damping units for cracks or deformation. Makes sure the vibration damping units are securely attached to the engine unit and handle unit.

- ON/STOP switch. Start the engine and makesuretheenginestopswhenyoumove theON/STOPswitchtotheSTOPposition.

MAINTAIN YOURSAW IN GOODWORKING ORDER

• Have all chains awservice performed by a qualified service dealer with the exception of the items listed in the maintenance section of this manual. Forexample, if impropertools are used to remove or hold the flywheel whenservicing the clutch, structural damage to the flywheel can occur and cause the flywheel to burst.
- Make certain the saw chain stops moving when the throttle trigger is released. For correction, refer to CARBURETORADJUSTMENTS.
- Nevermodify yoursawinanyway. Use onlyattachments suppliedorspecifically recommendedbythemanufacturer.
- Keep the handles dry, clean, and free of oil or fuel mixture.
- Keepfuelandoilcaps, screws, and fasteners securely tightened.
- Use only McCulloch accessories and replacement parts as recommended.

HANDLEFUEL WITHCAUTION

• Donotsmokewhilehandlingfuelorwhile operatingthesaw.
• Eliminate all sources of spark 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-ginetocool before refueling.
• Mixandpourfuelinanoutdoorareaonbare ground;storefuel inacool,dry,wellventilatedplace;and usean approved,marked containerforallfuelpurposes. Wipeupall fuelspillsbeforestartingsaw.
• Moveatleast10feet(3meters)fromfuelingsitebeforestartingengine.
• Turntheengineoffandletsawcoolina non-combustiblearea, notondryleaves, straw, paper, etc. Slowlyremovefuelcap andrefuelunit.
• Store the unit and fuel in an area where fuel vapors cannot reach sparks or open flames from waterheaters, electric motors or switches, furnaces, etc.

KICKBACK

WARNING: Avoid kickback which

canresultinserious injury. Kickbackisthe 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 objects such as a logarithor branch, or when the wood closes in and pinches the saw chain in the cut. Contacting a foreign object in the wood can also result in loss of chainsaw control.

- Rotational Kickback can occur when the movingchaincontactsanobjectatthe up-pertipoftheguidebar. This contactcan causethechaintodigintotheobject,

CHAINOIL

• We recommend the use of special oil (chainoil) with good adhesion characteristics.
• Neverusewasteoil. This results in damagetotheoilpump, the bar and the chain.
• It is important to use oil of the right grade (suitable viscosity range) to suit the air temperature.
• In temperatures below 0°C (32°F) some oilsbecometooviscous. This can overload the oil pump and result in damage to the oil pump components.
• Contactyourservicedealerwhenchoosingchainoil.

CHAIN BRAKE

WARNING: If the brake band is worn

too thin it may break when the chain brake is triggered. With abrokenbrakeband, the chain brakewill not stop the chain. The chain brake should be replaced by an authorized service dealer if any part is worst than 0,02" (0,5 mm) thick. Repair on a chain brakes should be made by an authorized service dealer. Take your unit to the place of purchase if purchased from servicing dealer, or to the arest a authorized masters serviced dealer.

AIR FILTER

CAUTION: Donotcleanfilteringaso-

Cleaning theair filter:

A dirty air filter decreases engine performance and increases fuel consumption and harmful emissions. Always clean after every 5 hour of operation.

STORAGE

WARNING: Stopengineandallowto cool, and secure the unit before storing or transporting in a vehicle. Store unit and fuel in an area where fuel vapors cannot reach sparks or open flames from water heaters, electric motors or switches, furnaces, etc. Store unit with all guards in place. Position so that any sharp object cannot accidentally cause injury to passers by. Store the unit out of reach of children.

• Beforestoring, drainallfuelfromthe unit. Start engine and allow to run until it stops.
• Clean the unit before storing. Pay particular attention to the air intake area, keeping itfreeofdebris.Useamild detergent and spongetocleantheplasticsurfaces.

• Donotstoretheunitorfuelinaclosedarea where fuel vapors can reach sparks or an openflamefromhotwaterheaters,electric motorsorswitches,furnaces,etc.
