FUELING & LUBRICATION FUELING ENGINE This engine is certified to operate on unleaded gasoline. Before operation, gasoline must be mixed with a good quality 2-cycle air-cooled engine oil. We recommend POULAN/WEED EATERR brand oil. If you do not use this oil, use a good quality 2-cycle air-cooled oil designed to be mixed at a ratio of 40:1 (A 40:1 ratio is obtained by mixing 3.2 ounces of oil with 1 gallon of unleaded gasoline). When mixing fuel follow the instructions printed on the container. Always read and follow the safety rules relating to fuel before fueling your unit. 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. Genuine POULAN or POULAN PRO bar and chain oil is recommended to protect your unit against excessive wear from heat and friction. POULAN or POULAN PRO oil resists high temperature thinning. If POULAN or POULAN PRO 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. MPORTANT Experience indicates that alcohol--blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while 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 the fuel lines and carburetor are empty. Use fresh fuel next season. See STORAGE section for additional information. STARTING WARNING: he 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. 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" of rope per pull. Hold saw firmly while pulling starter rope 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. NOTE: Do not attempt to cut material with the fast idle lock button in the locked position. STARTING A COLD ENGINE (or warm engine after running out of fuel). S Move ON/STOP switch to the ON position. S Pull choke knob out to the full extent. S Slowly press primer bulb 6 times. S Squeeze and hold throttle trigger. With thumb press fast idle lock down; then release throttle trigger. S Sharply pull the starter rope handle 5 times with your right hand. S Push the choke knob in completely (to the OFF position); pull the starter rope until the engine starts. S Allow the engine to run for approximately 5 seconds. Then, squeeze and release throttle trigger to allow engine to return to idle speed. Fast idle lock button Throttle lock--out Throttle trigger Choke knob IGNITION SWITCH SIDE VIEW ON STOP 9
