Operation Recommended Gasoline Note: Determine the left and right sides of the machine from the normal operating position. Use UNLEADED Regular Gasoline suitable for automotive use (87 pump octane minimum). Leaded regular gasoline may be used if unleaded regular is not available. Think Safety First Important: Never use methanol, gasoline containing methanol, or gasohol containing more than 10% ethanol because the fuel system could be damaged. Do not mix oil with gasoline.
• Cleans the engine while it runs • Eliminates gum-like varnish buildup in the fuel system, which causes hard starting In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. Important: Do not use fuel additives containing methanol or ethanol. Add the correct amount of gas stabilizer/conditioner to the gas.

Raise the seat and loosen the adjustment knobs enough to move the seat (Figure 13). Important: Make sure that the spacers stay in place when loosening the knobs to move the seat. Loss of the spacers can result in damage to the seat. 2. Move the seat to the desired position and tighten the knobs. Figure 14 1. 2. Control lever Bolt 3.
Side Discharge The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. Without the grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris will cause injury or death. Figure 15 1. Bypass levers 3. 2.
Cut 1/3 of the Grass Blade inside the mower, cutting quality will eventually become unsatisfactory. It is best to cut only about 1/3 of the grass blade. Cutting more than that is not recommended unless grass is sparse, or it is late fall when grass grows more slowly. Blade Maintenance Maintain a sharp blade throughout the cutting season because a sharp blade cuts cleanly without tearing or shredding the grass blades.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the rst 8 operating hours • Change the engine oil. Before each use or daily • • • • Check the safety interlock system. Check the engine oil level. Check the cutting blades. Clean the mower housing. Every 25 hours • • • • Grease all lubrication points.
