Install spacers on the wheel spindle above or below the wheel support as shown. Turn the spacers so the slot in the spacer does not align with the flat sides on the wheel spindle. Secure the spacers with the lock pin. (7). NOTE: Set both wheels at the same height for a level cut. Secure spacers above the caster arm with the lock pin. • Do not modify the fuel system to use different fuels. • Never mix oil and gasoline. NOTE: All gasoline is not the same. If the engine experiences starting or performance problems after using a new gasoline, switch to a different fuel provider or fuel brand. IMPORTANT: Excessively oxygenated or reformulated fuels (fuels blended with alcohols or ethers) can damage the fuel system or cause performance problems. If any undesirable operating problems occur, use a gasoline with a lower percentage of alcohol or ether. Fuel Stabilizer Gasoline left in the fuel system for extended periods without a stabilizer will deteriorate, resulting in gum deposits in the system. These deposits can damage the carburetor and the fuel hoses, filter and tank. Prevent deposits from forming in the fuel system during storage by adding a quality fuel stabilizer to the fuel. Follow the recommended mix ratio found on the fuel stabilizer container. To add fuel to the tank: 1. ALWAYS place unit in an open, wellventilated area. 2. Stop engine and allow to cool. Align open end of the spacers with the flat cut sides on the caster fork. Remove the spacers from the bottom of the stack. Figure 7 OS6080 FILLING FUEL TANK GASOLINE IMPORTANT: ALWAYS use gasoline that meets the following guidelines: • Clean, fresh gasoline. • A minimum of 87 octane/87 AKI (91 RON).
