STARTING AND STOPPING PRE-OPERATION INSPECTION Perform the following steps before every use of the machine: • Check fuel mixture level • Check bar lubrication • Check chain sharpness NOTE: Chain sharpening is a complicated task that requires special tools. We recommend that you refer chain sharpening to a professional chain sharpener. • Check chain tension • Inspect and clean the guide bar • Check for damaged parts • Check for loose caps • Check for loose fasteners • Check for loose parts • Check for fuel and oil leaks NOTE: It is normal for a small amount of oil to appear under the saw after the engine stops. Do not confuse this with a leaking oil tank. FUELING THE 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 consumer assistance help line. WARNING! Remove the fuel cap slowly when fueling. This equipment is designed to operate on unleaded gasoline with a minimum 87 octane (R+M/2 method), with ethanol blended up to 10% maximum by volume (E-10). Before operation, gasoline must be mixed with a good quality full synthetic 2-cycle air-cooled engine oil designed to be mixed at a ratio of 50:1. A 50:1 ratio is obtained by mixing 2.6 fluid ounces of full synthetic oil with 1 gallon of unleaded gasoline. DO NOT USE automotive oil or marine oil. These oils will cause engine damage. When mixing fuel, follow the instructions printed on the container. Once the oil is added to the gasoline, shake the container momentarily to assure that the fuel is thoroughly mixed. Fill the fuel tank completely with properly mixed fuel. Always read and follow the safety rules relating to fuel before fueling your unit. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness. HELPFUL TIP During storage of your fuel mixture, the oil will separate from the gasoline. Shake the fuel can weekly to insure proper blending of the gasoline and oil. CAUTION: Never use unmixed gasoline in your unit. This will cause permanent engine damage and void the limited warranty. CAUTION: Do not use alternate fuels such as ethanol blends above 10% by volume (E-15, E85) or any methanol blended fuel. Use of these fuels can cause major engine performance problems and void the limited warranty. 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. Fill the oil tank completely with oil. CAUTION: Never use waste oil for bar and chain lubrication. CAUTION: Always stop the engine before removing the oil cap. STARTING POSITION 1. Lay the chainsaw on a flat surface. The cutting attachment must not be in contact with the ground. 2. Lock the chain brake by pushing forward on the handguard. 3. Place your left hand on the handlebar and your right hand on the starter rope. Push your right foot into the rear handle to stabilize the chainsaw. 4. Follow the starting instructions. 8
