OPERATION n Clean the surface around the fuel cap to prevent contamination. n Loosen the fuel cap slowly. n Carefully pour the fuel mixture into the tank. Avoid spillage. n Prior to replacing the fuel cap, clean and inspect the o-ring. n Immediately replace the fuel cap and hand tighten. Wipe up any fuel spillage. NOTE: It is normal for the engine to emit smoke during and after the first use. WARNING: Always shut off engine before fueling. Never remove fuel cap or add fuel to a machine with a running or hot engine. Make sure unit is sitting on a flat, level surface and only add fuel outdoors. If the engine is hot, allow to cool for at least five minutes before adding fuel. Immediately replace fuel cap after fueling and tighten securely. Move at least 30 ft. from refueling site before starting the engine. Do not smoke and stay away from open flames and sparks. Failure to heed this warning can result in possible personal injury. Fig. 2 BAR AND CHAIN LUBRICATION See Figure 3. The bar and chain require continuous lubrication. Lubrication is provided by the automatic oiler system when the oil tank is kept filled. Lack of lubricant will quickly ruin the bar and chain. Too little lubricant will cause overheating shown by smoke coming from the chain and/or discoloration of the bar. Lubrication can be increased or decreased by turning (up to 1/4 turn maximum) the adjustment screw located on the bottom of the crankcase with the screwdriver end of the included combination wrench. WARNING: NEVER adjust the automatic oiler system when the engine is running. Failure to do so could cause serious personal injury. INCREASE DECREASE ADJUSTMENT SCREW SCREWDRIVER Fig. 3 ADDING BAR AND CHAIN LUBRICANT See Figure 3. Use a bar and chain lubricant designed for lubricating chain saw chains. They are formulated to extend bar and chain life by protecting against wear and reducing friction and heat. Chain saw should use approximately one tank of lubricant per tank of fuel. Page 13 - English
