Safety • Do not operate the mower without either the entire grass catcher or the guard in place. • Be alert, slow down and use caution when making turns. Look behind and to the side before changing directions. • Never leave a running machine unattended. Always turn off blades, set parking brake, stop engine, and remove key before dismounting. • Turn off blades when not mowing.
• Reduce speed and use extreme caution on slopes. • Do not make sudden turns or rapid speed changes. • Use a walk behind mower and/or a hand trimmer near drop-offs, ditches, steep banks or water. • Remove or mark obstacles such as rocks, tree limbs, etc. from the mowing area. Tall grass can hide obstacles. • Avoid sudden starts when mowing uphill because the mower may tip backwards. • Be aware that loss of traction may occur going downhill.
• Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until the fueling is complete. Do not use a nozzle lock-open device. • Engine exhaust contains carbon monoxide, which is an odorless, deadly poison that can kill you. Do not run engine indoors or in an enclosed area. • If fuel is spilled on clothing, change clothing immediately. • Stop the engine, disconnect spark plug wire(s) and remove key before performing any service, repairs, maintenance or adjustments.

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.
Stopping the Engine 1. Move the throttle lever to Fast (Figure 8). 2. Disengage the blades by moving the blade control switch to Off (Figure 7). 3. Turn the ignition key to Off (Figure 9).

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.
