CARBURETOR ADJUSTMENT WARNING: The chain will be moving during most of this procedure. Wear your protective equipment and observe all safety precautions. The chain must not move at idle speed. The carburetor has been carefully set at the factory. Adjustments may be necessary if you notice any of the following conditions: S Chain moves at idle. See IDLE SPEED--T adjusting procedure. S Saw will not idle. See IDLE SPEED--T adjusting procedure. Idle Speed--T Allow engine to idle. If the chain moves, idle is too fast. If the engine stalls, idle is too slow. Adjust speed until engine runs without chain movement (idle too fast) or stalling (idle too slow). The idle speed screw is located in the area above the primer bulb and is labeled T. S Turn idle screw (T) clockwise to increase engine speed. S Turn idle screw (T) counterclockwise to decrease engine speed. If you require further assistance or are unsure about performing this procedure, contact your authorized service dealer or call our customer assistance help line at 1--800--554--6723. COOLING SYSTEM To keep the working temperature as low as possible the machine is equipped with a cooling system. The cooling system consists of: S Air intake on the starter S Air guide plate S Fins on the flywheel S Cooling fins on the cylinder S Cylinder cover (directs cold air over the cylinder) Clean the cooling system with a brush after each use, more often in demanding conditions. A dirty or blocked cooling system results in the machine overheating which causes damage to the piston and cylinder. STORAGE WARNING: Perform the following steps after each use: S Allow the engine to cool, and secure the unit before storing or transporting. S Store chain saw and fuel in a well venti- lated area where fuel vapors cannot reach sparks or open flames from water heaters, electric motors or switches, furnaces, etc. S Store chain saw with all guards in place and position chain saw so that any sharp object cannot accidentally cause injury. S Store chain saw well out of the reach of children. SEASONAL STORAGE Prepare your unit for storage at the end of the season or if it will not be used for 30 days or more. If your chain saw is to be stored for a period of time: S Clean saw thoroughly before storage. S Store in a clean dry area. S Lightly oil external metal surfaces and guide bar. S Oil the chain and wrap it in heavy paper or cloth. FUEL SYSTEM Under FUELING ENGINE in the OPERATION section of this manual, see message labeled IMPORTANT regarding the use of gasohol in your chain saw. Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add stabilizer to the gasoline in the fuel tank or fuel storage container. 17
