Moving the control levers outward from the center position engages the parking brake and allows the operator to exit the machine (Figure 13). Always position the motion control levers into the park position when you stop the machine or leave it unattended. Note: Determine the left and right sides of the machine from the normal operating position.
Recommended Gasoline Use UNLEADED Regular Gasoline suitable for automotive use (87 pump octane minimum). Leaded regular gasoline may be used if unleaded regular is not available. 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.
Add the correct amount of gas stabilizer/conditioner to the gas. 4 Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times. 2 1 3 Gasoline/Alcohol blends Gasohol (up to 10 percent ethyl alcohol, 90 percent unleaded gasoline by volume) is approved for fuel use by the engine manufacturer. Other gasoline/alcohol blends are not approved.

Mowing Direction grass brown at the edges, which slows growth and increases the chance of disease. Check the cutter blades daily for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary. If a blade is damaged or worn, replace it immediately with a genuine Toro replacement blade. Alternate mowing direction to keep the grass standing straight. This also helps disperse clippings which enhances decomposition and fertilization.
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 Before each use or daily • • • • • • Check the safety interlock system. Check the air cleaner for dirty, loose or damaged parts. Check the engine oil level. Check air intake and cooling areas, clean as necessary. Check the cutting blades. Clean the mower housing.
Premaintenance Procedures Lubrication Raising the Seat Service Interval: Every 25 hours—Grease all lubrication points. Greasing the Bearings Make sure the motion control levers are locked in the park position. Lift the seat forward and lower it to the floor board. Grease Type: No. 2 General Purpose Lithium Base Grease The following components can be accessed by raising the seat: 1. Park the machine on a level surface and disengage the blade control switch. • Serial plate 2.
Engine Maintenance 4. Connect a grease gun to each fitting (Figure 19 and Figure 20). Pump grease into the fittings until grease begins to ooze out of the bearings. Servicing the Air Cleaner 5. Wipe up any excess grease. Service Interval: Before each use or daily—Check the air cleaner for dirty, loose or damaged parts. This engine is equipped with a replaceable, high density paper air cleaner element. Check the air cleaner daily or before starting the engine.
Replace a dirty, bent, or damaged element. Handle new elements carefully; do not use if the rubber seal is damaged. 1 4. Clean all air cleaner components of any accumulated dirt or foreign material. Prevent any dirt from entering the carburetor. 5. Install the air cleaner element with the pleated side “out” and seat the rubber seal onto the edges of the air cleaner base (Figure 21). 2 6. Reinstall the air cleaner cover and secure with the two knobs (Figure 21).
2. Park the machine so that the drain side is slightly lower than the opposite side to assure the oil drains completely. 3. Disengage the blade control switch and move the motion controls outward to the park position. 4. Stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 5. Clean the area around the drain plug and on the machine frame.

Drive System Maintenance Mower Maintenance Checking the Tire Pressure Maintain sharp blades throughout the cutting season because sharp blades cut cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. Servicing the Cutting Blades Service Interval: Every 25 hours—Check tire pressure. Maintain the air pressure in the front and rear tires as specified. Uneven tire pressure can cause uneven cut.
Removing the Blades The blades must be replaced if a solid object is hit, if the blade is out of balance, or the blade is bent. To ensure optimum performance and continued safety conformance of the machine, use genuine Toro replacement blades. Replacement blades made by other manufacturers may result in non-conformance with safety standards. Figure 33 1. Cutting edge 2. Curved area 3. Wear/slot forming Hold the blade end using a rag or thickly-padded glove.
Figure 37 1. Blade 2. Balancer Installing the Blades 1. Install the blade onto the spindle shaft (Figure 35). Important: The curved part of the blade must be pointing upward toward the inside of the mower to ensure proper cutting. Figure 38 1. Blades side to side 2. Outside cutting edges 2. Install the blade stiffener, the curved washer (cupped side toward the blade) and the blade bolt (Figure 35). 3. Measure here 6. Measure between the outside cutting edges and the flat surface (Figure 38).
