Poulan P3816 User Manual - Page 9

WARNING: If the saw is operated with a loose chain, the chain could jump off the guide bar and result in serious injury to the operator and/or damage the chain making it unusable. BEFORE STARTING ENGINE WARNING: Muffler is very hot during and after use. Do not touch the muffler or allow combustible material such as dry grass or fuel to do so. 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 slowly 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 fluid 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. 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 gas- oline) such as E--15 (15% alcohol), E--20 (20% alcohol), E--85 (85% alcohol) are NOT classified as gasoline and are NOT approved for use in 2--stroke gasoline engines. Use of alternative 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. 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. 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. Use only 15″ -- 18″ (40 -- 45 cm) of rope per pull. Hold saw firmly while pulling starter rope. Starter Rope Handle Left Hand on Front Handle Right Foot Through Rear Handle WARNING: Do not attempt to throw or drop--start the chain saw. Doing so will put the operator at risk of serious injury due to loss of control of the chain saw. 9
