THROTTLE LOCK--OUT The THROTTLE LOCK--OUT must be pressed before you can squeeze the throttle trigger. This feature prevents you from accidentally squeezing the trigger. CHOKE/FAST IDLE LEVER The choke and fast idle are set by pulling the CHOKE/FAST IDLE LEVER out to the full extent for cold starting or after refueling. The choke provides additional fuel to the engine during cold starting. PRIMER BULB The PRIMER BULB circulates fuel to the carburetor to provide quicker starting. WARNING: Muffler is very hot dur- ing and after use. Do not touch the muffler or allow combustible material such as dry grass or fuel to do so. BEFORE STARTING ENGINE WARNING: Be sure to read the fuel handling information in the safety rules section of this manual before you begin. If you do not understand the fuel handling information do not attempt to fuel your unit. Seek help from someone that does understand the information or call the customer assistance help line at 1-800-554-6723. FUELING ENGINE WARNING: Remove fuel cap slow- ly when refueling. HELPFUL TIP To obtain the correct oil mix ratio, pour 3.2 ounces of 2- cycle synthetic oil into one gallon of fresh gas. This engine is certified to operate on unleaded gasoline. Before operation, gasoline must be mixed with a good quality synthetic 2-cycle aircooled engine oil designed to be mixed at a ratio of 40:1. Poulan/WEED EATER brand synthetic oil is recommended. A 40:1 ratio is obtained by mixing 3.2 ounces (95 ml) of oil with 1 gallon (4 liters) of unleaded gasoline. Included with this saw is a 3.2 ounce (95 ml) container of Poulan/WEED EATER brand synthetic oil. Pour the entire contents of this container 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. Always read and follow the safety rules listed under HANDLE FUEL WITH CAUTION. 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. CHAIN BRAKE The chain brake is a device designed to stop the chain if kickback occurs. The chain brake activates automatically in the event of kickback. The chain brake activates manually if the front hand guard is pushed forward. The chain brake is disengaged by pulling the front hand guard back toward the front handle as far as possible. CHAIN TENSION It is normal for a new chain to stretch during the first 15 minutes of operation. You should check your chain tension frequently. See CHAIN TENSION under the ASSEMBLY section. 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 bar and chain oil is recommended to protect your unit against excessive wear from heat and friction. Poulan oil resists high temperature thinning. If Poulan 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. IMPORTANT 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. 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. 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. 9
