CONTROLS Fuel tank Underneath the tank, there is a fuel filter combined with the fuel valve. The tank volume is 1.72 Gal. (6.5 liters) Fueling Read the safety instructions before fueling. Keep the fuel and fuel tank clean. Avoid filling the machine with dirty fuel. Make sure the fuel cap is properly tightened and the gasket is not damaged, particularly before washing the machine. Use unleaded gasoline with minimum 86 octane rating. Never use gasoline mixed with two-cycle oil. For ethanol and methanol fuel, the following applies: Maximum allowable ethanol 10% (volume). Maximum allowable methanol 5% (volume). Maximum allowable MTBE (Methyl Tertiary Butyl Ether) 15% (volume). If the engine "bolts" at normal load it can be damaged. Change the fuel. If this does not help, contact an authorized service workshop. Do not fill the tank completely; leave space for the fuel to expand as it warms up. 8011-222chg WARNING! Gasoline is highly flammable. Observe caution and fill the tank outdoors. (See the safety instructions.) Centrifugal clutch The engine is equipped with a centrifugal clutch that is connected to the crankshaft. When the engine speed increases, the drive for the cutting wheel engages automatically. The centrifugal clutch is maintenance-free; it is not possible for the user to make adjustments. Cutting unit Dead man's grip bar The bar must be held against the handle for the engine to run. If you release the grip, the ignition system short-circuits and the engine stops. 8011-247 WARNING! Do not bind the bar to the handle. It is there for your safety. 22
