Before operation, gasoline must be mixed with a good quality synthetic 2-cycle air-cooled engine oil designed to be mixed at a ratio of 40:1. A 40:1 ratio is obtained by mixing 3.2 fluid ounces (95 ml) of oil with 1 gallon (4 liters) of unleaded gasoline. Pour the entire contents of the 3.2 ounce (95 ml) container of oil into 1 gallon (4 liters) of gasoline to achieve the proper fuel mixture. DO NOT USE automotive or marine oil. These oils will cause engine damage. When mixing fuel follow the instructions printed on the container. Once oil is added to gasoline, shake container momentarily to assure that the fuel is thoroughly mixed. Always read and follow the safety rules relating to fuel before fueling your unit. CAUTION: Never use straight gasoline in your unit. This will cause permanent engine damage and void the limited warranty. FUEL REQUIREMENTS This engine requires the use of minimum 87 octane [R+M]/2 clean gasoline. IMPORTANT Use of alcohol blended fuels (called gasohol or using ethanol or methanol) can cause major engine performance and durability problems. WARNING: Alternative fuels (not gasoline) such as E- --15 (15% alcohol), E- --20 (20% alcohol), E- --85 (85% alcohol) are NOT classified as gasoline and are NOT approved for usein2- --strokegasolineengines. Useofalternative fuels will cause problems such as: improper clutch engagements, overheating, vapor lock, power loss, lubrication deficiency, deterioration of fuel lines, gaskets and internal carburetor components, etc. Alternative fuels cause high moisture absorption into the fuel/oil mixture leading to oil and fuel separation. BAR AND CHAIN LUBRICATION The bar and chain require continuous lubrication. Lubrication is provided by the automatic oiler system when the oil tank is kept filled. Lack of oil will quickly ruin the bar and chain. Too little oil will cause overheating shown by smoke coming from the chain and/ or discoloration of the bar. In freezing weather oil will thicken, making it necessary to thin bar and chain oil with a small amount (5 to 10%) of #1 Diesel Fuel or kerosene. Bar and chain oil must be free flowing for the oil system to pump enough oil for adequate lubrication. If bar and chain oil is not available, use a good grade SAE 30 oil. S Never use waste oil for bar and chain lubri cation. S Always stop the engine before removing the oil cap. CHAIN BRAKE Ensure 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 must not move when the engine runs at idle speed. If the chain moves at idle speed refer to CARBURETOR ADJUSTMENT within this manual. Avoid contact with the muffler. A hot muffler can cause serious burns. 9 To stop the engine move the ON/STOP switch to the STOP position. To start the engine hold the saw firmly on the ground as illustrated. Make sure the chain is free to turn without contacting any object. Use only 15. --18. (40 - --45cm)of rope per pull. Hold saw firmly while pulling starter rope. Starter Rope Handle Handle RightFootThroughRearHandle Left Hand on Front WARNING: Do not attempt to throw or drop- --start thechainsaw. Doingso will put the operator at risk of serious injury due to loss of control of the chain saw. 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. NOTE: Do not attempt to cut material with the choke/fast idle lever in the FULL CHOKE position. HELPFULTIPIfyourenginestilldoesnotstartafterfollowingtheseinstructions,pleasecall1--800--554--6723.
