It also prevents damage to the housing from wear. IMPORTANT: DO NOT allow scraper blade to wear too far or auger/impeller housing will become damaged. The skid shoes control the distance between the scraper blade and the ground. Adjust skid shoes equally to keep blade level with the ground. Refer to Pre-Start on page 15 for recommended settings. FILLING FUEL TANK WARNING: AVOID INJURY. Read and understand the entire Safety section before proceeding. GASOLINE Fuel Recommendations Use unleaded gasoline with a pump octane rating of 86 or higher. These engines operate best on unleaded gasoline.

CAUTION: DO NOT use E85 blended fuels. This engine is not E20/E30/E85 compatible. Maximum recommended ethanol content: 10% Adding a Fuel Stabilizer to Extend Fuel Storage Life NOTE: Fuel stabilizer is recommended for long term storage. 1. Turn the fuel valve off while engine is running and allow the engine to run until it stops. Turn engine OFF when it begins surging to avoid engine damage. 2. Add fuel stabilizer, following the manufacturer’s instructions. 3. Turn fuel valve on after adding fuel stabilizer. 4. Re-start engine. 5.
