STARTING/STOPPING INSTRUCTIONS
WARNING: Operate this unit only in a
outdoor area. Carbon
monoxide exhaust fumes can be lethal in a confined area.
WARNING: Never operate the saw without the bar and
chain properly
installed.
BEFORE STARTING ENGINE
WARNING: Be sure to read the Oil and Fuel Information Section of this manual before you begin. If you do not
understand the oil and fuel information, do not attempt to fuel your unit. For more information contact your local Sears service center at
GUIDE BAR AND CHAIN OIL
The bar and chain require lubrication. The chain oiler provides continuous lubrication to the chain and guide bar. Be sure to fill the bar oil tank when you fill the fuel tank. (Capacity = 6.8 fl. oz.). Lack of oil will quickly ruin the bar and chain. Too little oil will cause over- heating with smoke coming from the chain and discol- oration of the bar. For maximum guide bar and chain life, we recommend you use Craftsman chain saw bar oil. If Craftsman bar oil is not available, you may use a good grade SAE 30 oil until you are able to obtain the Craftsman brand. The oil output is automatically metered during operation. Your saw will use approxi- mately one tank of bar oil for every tank of fuel mix. Always fill the bar oil tank when you fill the fuel tank.
FUELING THE ENGINE
WARNING: Remove fuel cap slowly when refueling.
This engine is certified to operate on unleaded gaso- line. Before operation, gasoline must be mixed with a good quality synthetic
We recommend Craftsman brand synthetic oil. Mix gasoline and oil at a ratio of 40:1. 40:1 ratio is obtained by mixing 3.2 ounces of oil with 1 gallon of unleaded gasoline. Included with this saw is a 3.2 ounce container of oil. Pour the entire contents of this container into one gallon of gasoline to achieve the proper fuel mixture. DO NOT use automotive oil or boat oil. These oils will cause engine damage. When mixing fuel, follow the instructions printed on the oil container. Once oil is added to the gasoline, shake container momentarily to assure that the fuel is thor- oughly mixed. Always read and follow the safety rules relating to fuel before fueling your unit.
IMPORTANT:
Experience indicates that alcohol blended with fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and forma- tion of acids during storage. Acidic gas can damage the fuel system of an engine when in storage. To avoid engine problems, the fuel system should be emptied before storage for 30 days or longer. Drain the gas tank, start the engine and let it run until fuel lines and carburetor are empty. Use fresh fuel next season. Never use engine or carburetor cleaner products in the fuel tank or permanent damage can occur. See STOR- AGE instructions for additional information.
CHAIN BRAKE
Be sure the chain brake is disengaged by pulling the front hand guard back toward the front handle as far as possible. The chain brake must be disengaged before cutting with the saw.
WARNING: The chain brake must not move when the engine runs at idle speed. If the chain brake moves at idle speed, refer to CARBURETOR ADJUSTMENT in this manual. Avoid contact with the muffler. A hot muf- fler can cause serious burns.
IMPORTANT POINTS TO REMEMBER
When pulling the starter rope, do not use the full extent of the rope as this can cause the rope to break. Do not let starter rope snap back. Hold the handle and let the rope rewind slowly. For cold weather starting, start the unit at FULL CHOKE; allow the engine to warm up before squeezing the throttle trigger.
DO NOT attempt to cut material with the choke/fast idle lever in the FULL CHOKE position.
