Unlock - Wheel Swivels Lock - Wheel Held Straight OM1700 FILLING THE FUEL TANK GASOLINE IMPORTANT: ALWAYS use gasoline that meets the following guidelines: • Clean, fresh gasoline. • A minimum of 87 octane/87 AKI (91 RON). High altitude use may require a different octane. Consult your engine manual. • Gasoline with up to 10% ethanol (gasohol) or up to 15% MTBE (methyl tertiary butyl ether) is acceptable. • Use of any gasoline other than those approved above may void the engine warranty. If the pumps are not marked for the content of alcohol or ethers, check ethanol and MTBE levels with the fuel supplier. • 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 fuel tank: 1. Put unit in open or well-ventilated area. 2. Stop engine and allow to cool. 3. Clean fuel cap and surrounding area. 4. Remove cap. IMPORTANT: See engine manual for correct type and grade of fuel. 5. Fill fuel tank. (see SPECIFICATIONS on page 27page 27 for tank capacity.) Do not overfill. 6. Replace fuel cap and tighten. 7. ALWAYS clean any spilled fuel. MOWER SET-UP CAUTION: DO NOT operate mower unless either side discharge cover or side discharge deflector is installed. Thrown objects may cause damage or injury. Never operate unit with rear door open unless grass bag is in place. CAUTION: If clog or obstruction prevents grass flow, release engine/blade control and disconnect spark plug wire before attempting to clear away any clogs. GB - 14
