PLEASE READ Dear Customer, Thank you for purchasing a McCulloch product. With proper operation and maintenance, it will provide you with years of service. In order to make the best use of your investment, be CERTAIN to familiarize yourself with the contents of the ENTIRE user manual before attempting to operate and maintain your unit.
1- IMPORTANT SAFETY PRECAUTIONS - PRÉCAUTIONS DE SECURITE IMPORTANTES - PRECAUCIONES DE SEGURIDAD IMPORTANTES Your McCulloch Chain Saw is provided with a safety label located on the CHAIN BRAKE with the safety instructions on these pages, should be carefully read before attempting to operate your saw. 1-1.
WARNING (Figure 2-1A) 1. Avoid bar nose contact. 2. Beware of kick back. 3. Do not attempt to hold saw with one hand. 1-2. IMPORTANT SAFETY INSTRUCTIONS 1. REPLACEMENT PARTS - When servicing use only identical replacement parts. 2. POLARIZED PLUGS - To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider than the other).
4. CONSIDER THE WORK AREA ENVIRONMENT: Use extreme caution when cutting small sized brush and saplings because the slender material may catch the saw chain and be whipped toward you or pull you off bal- ance. Do not operate a chain saw in a tree unless specifically trained to do so. When cutting a limb that is under tension, be alert for spring back so that you will not be struck when the tension in the wood fibers is released.
10. DRESS PROPERLY: Do not wear loose clothing or jewelry. They can get caught in moving parts. Rubber gloves and non-skid footwear are recommended when working outdoors. Wear protective hair covering to contain long hair. 11. USE SAFETY GLASSES: Also use safety footwear; snug fitting clothing; protective gloves; head and protection. 12.
16. STAY ALERT: Watch what you are doing. Use common sense. Do not operate the chain saw when you are tired. Keep all parts of the body away from the saw chain when the motor is operating. Before you start the saw, make sure the saw chain is not contacting anything.
B. Do not over reach. C. Keep proper footing and balance at all times. D. Don’t let the nose of the guide bar contact a log, branch, ground or other obstruction. E. Do not cut above shoulder height. F. Use devices such as low kickback chain, guide bar nose guards, chain brakes and special guide bars that reduce the risks associated with kickback.
4. TO REDUCE potential for electric shock, do not operate the saw on wet or slippery surfaces, or during snow storms, rain storms, and other adverse weather conditions. 5. Keep the handles dry, clean, and free of oil or grease. 6.
15. All chain saw service, other than the items listed in the user manual safety and maintenance instructions, should be performed by competent chain saw personnel. Do not attempt to repair it yourself; there are no user servicea- ble parts inside. 16.
1-4. GENERAL SAFETY PRECAUTIONS FOR CHAIN SAW USERS 1. Fatigue causes carelessness. Be more cautious before rest periods and towards the end of your shift. 2. Personal protective clothing required by your safety organizations, government regulations, or your employer should be used. At all times when using a chain saw, snug-fitting clothing, protective eye wear, safety footwear, and hand, leg, and hearing protection should be worn.
8. Do not attempt a pruning or limbing operation in a standing tree unless specifically trained to do so. 9. Guard against kickback. Kickback is the upward motion of the guide bar that occurs when the saw chain, at the nose of the guide bar, contacts an object.
1-5. MORE ABOUT KICKBACK WARNING DANGER! BEWARE OF KICKBACK! Kickback can lead to dangerous loss of control of the chain saw and result in serious or fatal injury to the saw opera- tor or to anyone standing close by. Always be alert because rotational kickback and pinch kickback are major chain saw operational dangers and the leading cause of most accidents.
KICKBACK may occur when the NOSE or TIP of the guide bar touches an object, or when wood closes in and pinch- es the saw chain in the cut. Tip contact in some cases may cause a lightening-fast reverse reaction, kicking the guide bar up and back toward the operator.

WARNING Do not operate your chain saw in a wet or damp environment. Do not expose the saw to rain, snow or sleet. Moisture will cause short circuits. Replace or repair any damaged or frayed extension cords before using your saw. Keep the cord away from the cutting area and position the cord so that it will not be caught on branches or other objects during cutting.
5 - GENERAL CUTTING INSTRUCTIONS - INSTRUCCIONES POUR LA COUPE - INSTRUCCIONES DE CORTADO GENERALES 5-1. FELLING Felling is the term for cutting down a tree. Small trees up to 6-7” (15-18cm) in diameter are usually cut in a single cut. Larger trees require notch cuts. Notch cuts determine the direction the tree will fall.
WARNING Do not cut down a tree during high or changing winds or if there is a danger to property. Consult a tree professional. Do not cut down a tree if there is a danger of striking utility wires; noti- fy the utility company before making any cuts.
Never saw completely through the trunk. Always leave a hinge. The hinge guides the tree. If the trunk is completely cut through, control over the felling direction is lost. Insert a wedge or felling lever in the cut well before the tree becomes unstable and starts to move. This will prevent the guide bar from binding in the felling cut if you have misjudged the falling direction.
WARNING As the felling cut gets close to the hinge, the tree should begin to fall. When tree begins to fall, remove saw from cut, stop engine, put chain saw down, and leave area along retreat path (Figure 5-1A). page 29 5-2.
5-3B 5-3. BUCKING Bucking is cutting a fallen log into lengths. Make sure you have a good footing and stand uphill of the log when cut- ting on sloping ground. If possible, the log should be supported so that the end to be cut off is not resting on the ground.
5-4. BUCKING USING A SAWHORSE For personal safety and ease of cutting, the correct position for vertical bucking is essential (Figure 5-4A). VERTICAL CUTTING: A. Hold the saw firmly with both hands and keep the saw to the right of your body while cutting. B Keep the left arm as straight as possible.
6 - BAR / CHAIN MAINTENANCE - ENTRETIEN DU GUIDE-CHAINE ET DE LA CHAINE - MANTENIMIENTO DE LA BARRA / CADENA 6-1. GUIDE BAR MAINTENANCE WARNING Ensure that the power cord is disconnected before performing any maintenance on your saw. Proper maintenance of the guide bar, as explained in this section, is essential to keep your saw in good work- ing order.
The disposable Lube Gun is packed with grease. For information on where to purchase a lube gun, contact the MTD Product Service Department toll-free number listed on the back cover of this manual. To Lubricate Sprocket Tip: WARNING Wear heavy duty work gloves when performing this application to reduce risk of personal injury. 1.
GUIDE BAR MAINTENANCE Most guide bar problems can be prevented merely by keeping the chain saw well maintained. Incorrect filing and non-uniform cutter and depth gauge settings cause most guide bar problems, primarily resulting in uneven bar wear. As the bar wears unevenly, the rails widen, which may cause chain clatter and difficulty in making straight cuts.
2. Using a screwdriver, putty knife, wire brush or other similar instrument, clear residue from the rails on the guide bar. This will keep the oil passages open to provide proper lubrication to the bar and chain (Figure 6-1B). 3. Reinstall the bar, chain, sprocket cover and bar bolt knob. (See Section 3-3, page 20). 6-2.
What is a Low-Kickback Saw Chain? A low-kickback saw chain is a chain which has met the kickback performance requirements of ANSI B175.1. By keeping the CHAIN BRAKE this manual, you will be able to maintain the safety system of your chain saw over the life of the product. WARNING Never remove, modify or make inoperative any safety device furnished with your unit.
BREAKING IN A NEW SAW CHAIN A new chain and bar will need readjustment after as few as 5 cuts. This is normal during the break-in period, and the interval between future adjustments will begin to lengthen quickly. Over a period of time, however, the moving parts of the saw chain will become worn, resulting in what is called CHAIN STRETCH.
7- PREVENTIVE MAINTENANCE - ENTRETIEN PREVENTIF - INSTRUCCIONES DE MANTENIMIENTO 7-1.
