Operating Tips Avoid Cutting Too Low Fast Throttle Setting If the cutting width of the mower is wider than the mower you previously used, raise the cutting height to ensure that uneven turf is not cut too short. 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 in uncut grass.
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 the cutting blades. Inspect the grass deflector for damage. After each use • Clean the mower-deck housing.
Pre-Maintenance Procedures Lubrication Raising the Seat Service Interval: Every 25 hours—Grease all the lubrication points. Make sure that the motion-control levers are locked in the PARK position. Lift the seat forward. Grease Type: No. 2 lithium grease Greasing the Bearings You can access the following components by raising the seat: • Serial plate 1. Park the machine on a level surface and disengage the blade-control switch. 2.
5. Engine Maintenance Pump grease into the fittings until grease begins to ooze out of the bearings. Servicing the Air Cleaner Service Interval: Before each use or daily—Check the air cleaner for dirty, loose or damaged parts. Every 50 hours—Service the air-cleaner paper element (more often under extremely dusty, dirty conditions). Every 100 hours—Replace the air-cleaner paper element (more often under extremely dusty, dirty conditions).

Changing the Engine Oil and the Engine-Oil Filter Service Interval: Every 100 hours—Change the engine oil and the engine-oil filter. Note: The drain plug is attached to the drain hose. Note: Dispose the used oil at a recycling center. Fill with oil as specified in the “Viscosity Grades” table (Figure 28). 1. Park the machine so that the drain side is slightly lower than the opposite side to ensure that the oil drains completely. 2.
g027478 Figure 33 Checking the Spark Plug Important: Do not clean the spark plug(s). Always replace the spark plug(s) when it has: a black coating, worn electrodes, an oily film, or cracks. Note: If you see light brown or gray on the insulator, the engine is operating properly. A black coating on the insulator usually means the air cleaner is dirty. Set the gap to 0.76 mm (0.030 inch).
Installing the Spark Plug Fuel System Maintenance Tighten the spark plug to 25 to 29 N·m (18 to 22 ft-lb). DANGER 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. • Perform any fuel-related maintenance when the engine is cold. Do this outdoors in an open area. Wipe up any gasoline that spills.
Electrical System Maintenance WARNING CALIFORNIA Proposition 65 Warning Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling. g027959 Charging the Battery Removing the Battery WARNING 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.
Charging the Battery WARNING Incorrect battery-cable routing could damage the machine and cables causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury. Service Interval: Before storage—Charge the battery and disconnect the battery cables. • Always disconnect the negative (black) battery cable before disconnecting the positive (red) cable. 1. Remove the battery from the chassis; refer to Removing the Battery (page 35). 2.
Servicing the Fuses Drive System Maintenance The electrical system is protected by fuses. It requires no maintenance; however, if a fuse blows, check the component or circuit for a malfunction or short. Checking the Tire Pressure Fuse type: • Main—F1-30 amp, blade-type Service Interval: Every 25 hours—Check tire pressure. • Charge Circuit—F2-25 amp, blade-type 1. Maintain the air pressure in the front and rear tires as specified. Uneven tire pressure can cause uneven cut.
Mower Maintenance Releasing the Electric Brake Servicing the Cutting Blades The electric brake releases by manually rotating the link arms forward. Once the electric brake is energized the brake resets. Maintain sharp blades throughout the cutting season, because sharp blades cut cleanly without tearing or shredding the grass blades. Tearing and shredding the grass turns it brown at the edges, which slows growth and increases the chance of disease.
