In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property. 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. • Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any gasoline that spills.
tank (Figure 9). This space in the neck of the tank allows gasoline to expand. Do not fill the fuel tank completely full. Add the correct amount of gas stabilizer/conditioner to the gas. 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. 4. Install the fuel tank cap securely. Wipe up any gasoline that may have spilled.

The Safety Interlock System If safety interlock switches are disconnected or damaged the machine could operate unexpectedly causing personal injury. 2 • Do not tamper with the interlock switches. G005185 1 • Check the operation of the interlock switches daily and replace any damaged switches before operating the machine. Figure 13 1. Control panel 2.
Driving Forward or Backward To turn, release pressure on the motion control lever toward the direction you want to turn (Figure 15). The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Place the throttle control in the Fast position for best performance. Always operate in the full throttle position. The farther you move the motion control levers in either direction, the faster the machine will move in that direction.
Adjusting the Height of Cut Adjusting the Motion Control Levers 1. Raise the height-of-cut lever to the transport position, cutting height position G (also the 4-1/2 inch [115 mm]) (Figure 16). Adjusting the Height The motion control levers can be adjusted higher or lower for maximum operator comfort. 1. Remove the 2 bolts holding the control lever to the control arm shaft (Figure 18). 2. Move the control lever to the next set of holes. Secure the lever with the 2 bolts (Figure 18).
To Push the Machine 1. Park the machine on a level surface and disengage the blade control switch. 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. 2.
Operating Tips Fast Throttle Setting For best mowing and maximum air circulation, operate the engine at the Fast position. Air is required to thoroughly cut grass clippings, so do not set the height-of-cut so low as to totally surround the mower by uncut grass. Always try to have one side of the mower free from uncut grass, which allows air to be drawn into the mower.
Long Grass If the grass is ever allowed to grow slightly longer than normal, or if it contains a high degree of moisture, raise the cutting height higher than usual and cut the grass at this setting. Then cut the grass again using the lower, normal setting. When Stopping If the machine’s forward motion must be stopped while mowing, a clump of grass clippings may drop onto your lawn. To avoid this, move onto a previously cut area with the blades engaged.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval Before each use or daily Maintenance Procedure • • • • • • • 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. Inspect the grass deflector for damage 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. 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 22 and Figure 23). 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.
Servicing Paper Element Checking the Oil Level Service Interval: Every 50 hours—Service the paper element. (more often under extremely dusty, dirty conditions) Service Interval: Before each use or daily—Check the engine oil level. 1. Park the machine on a level surface, disengage the blade control switch, stop the engine, and remove the key. Every 100 hours—Replace the paper element.

low, add oil of the proper type up to the full mark. Reinstall oil fill cap/dipstick and screw tight. Changing the Oil and the Filter 4 Service Interval: Every 100 hours—Change the engine oil and filter. Refill with service class SG, SH, SJ or higher oil as specified in the “Viscosity Grades” table. Change the oil and filter while the engine is still warm. The oil will flow more freely and carry away more impurities. Make sure the engine is level when filling, checking, or changing the oil.
12. Install the replacement oil filter to the adapter. Turn the oil filter clockwise until the rubber gasket contacts the pad, then tighten the filter an additional 3/4 to 1 turn (Figure 28). Wipe up any excess oil on the frame. 13. When oil has drained completely, install the oil drain plug. Tighten the plug to 14 N-m (125 in-lb) torque. Wipe up any excess oil (Figure 27). Note: Dispose of the used oil at a recycling center. 14.
Cleaning the Blower Housing Fuel System Maintenance To ensure proper cooling, make sure the grass screen, cooling fins, and other external surfaces of the engine are kept clean at all times. Annually or every 100 hours of operation (more often under extremely dusty, dirty conditions), remove the blower housing and any other cooling shrouds. Clean the cooling fins and external surfaces as necessary. Make sure the cooling shrouds are reinstalled. Torque the blower housing screws to 5.5 ft-lb (7.5 N-m).
Electrical System Maintenance 6 Charging the Battery 1 Removing the Battery 3 5 Battery terminals or metal tools could short against metal machine components causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury. G005071 2 4 • When removing or installing the battery, do not allow the battery terminals to touch any metal parts of the machine. Figure 31 1. Fuel line from tank 2. Hose clamp 3. Filter 4.

Drive System Maintenance Checking the Tire Pressure 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. Check the pressure at the valve stem (Figure 35). Check the tires when they are cold to get the most accurate pressure reading. G005073 Rear Tires: 13 psi (90 kPa) 1 2 Front Tires (caster wheels): 35 psi (241 kPa) Figure 34 1. Main-30 amp 2. Charge circuit-25 amp Figure 35 1.
Mower Maintenance Servicing the Cutting Blades 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. Figure 36 1. Cutting edge 2. Curved area Check the cutter blades daily for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary.
A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders. Figure 39 1. Sharpen at original angle • Always replace bent or damaged blade with a new blade. 2. Check the balance of the blade by putting it on a blade balancer (Figure 40). If the blade stays in a horizontal position, the blade is balanced and can be used. If the blade is not balanced, file some metal off the end of the sail area only (Figure 39). Repeat this procedure until the blade is balanced.
5. Carefully rotate the blade(s) side to side (Figure 41). If both measurements are not within 3/16 inch (5 mm), an adjustment is required; continue with this procedure. 4 1 3 6 2 5 Figure 41 1. Blades side to side 2. Outside cutting edges G005074 3. Measure here 6. Measure between the outside cutting edges and the flat surface (Figure 41). If both measurements are not within 3/16 inch (5 mm), an adjustment is required; continue with this procedure. Figure 42 1. Hanger bracket 2.
is 1/16-5/16 inch (1.6-7.9 mm) lower than the rear blade tip (Figure 43). 6. Measure from the tip of the front blade to the flat surface and the tip of the rear blade to the flat surface (Figure 43). If the front blade tip is not 1/16-5/16 inch (1.6-7.9 mm) lower than the rear blade tip, adjust the front locknut. 10. When the front-to-rear blade slope is correct check the side-to-side level of the mower again; refer to Leveling the Mower from Side-to-Side. Removing the Mower 1.
