Adjusting the tension: Chain tension is very important. Chain stretches during use. This is especially true during the first few times you use your saw. Always check chain tension each time you use and refuel your saw. You can adjust chain tension by loosening the bar clamp nuts and turning adjusting screw 1/4 of a turn while lifting up on the bar. S If chain is too tight, turn adjusting screw 1/4 turn counterclockwise. S If chain is too loose, turn adjusting screw 1/4 turn clockwise. S Lift up the tip of the bar and tighten the bar clamp nuts with the assembly tool. S Recheck chain tension. Tension is correct when chain does not sag below the bar but still can be moved around the bar. 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 lubrication. S Always stop the engine before removing the oil cap. Oil Cap Fuel mix cap STARTING Lifts only 1/8 of an inch from bar. Adjusting Screw 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 Eater 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 onces 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. 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 switch to the STOP or OFF position. To start the engine hold the saw firmly on the ground as illustrated below. Make sure the chain is free to turn without contacting any object. S Move switch to the START or ON position. IGNITION SWITCH (START) ON OFF (STOP) 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. For cold weather starting, start the unit at full choke; allow the engine to warm up before squeezing the throttle trigger. Do not cut material with the choke lever at the FULL position. 6
