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 first 5 hours • Change the engine oil. Before each use or daily • • • • • Check the safety-interlock system. Clean and check the air cleaner foam element. Clean the engine air-intake screen. Check the cutting blades. Inspect the grass deflector for damage.
Lubrication Engine Maintenance Greasing the Bearings Servicing the Air Cleaner Service Interval: Every 25 hours—Grease all the lubrication points. Service Interval: Before each use or daily—Clean and check the air cleaner foam element. Grease Type: No. 2 General Purpose, Lithium-Base Grease 1. Park the machine on a level surface, and disengage the blade-control switch. 2.
Servicing the Engine Oil Oil Type: Detergent oil (API service SF, SG, SH, SJ, or higher) Crankcase Capacity: 1.0 L (34 oz) when you do not change the filter; 1.05 L (36 oz) when you change the filter. Viscosity: See the table below. Figure 28 1. Foam element 2. Paper element 6. Separate the foam and paper elements. Cleaning the Foam and Paper Elements Figure 29 Foam Element: 1. Wash the foam element in liquid soap and warm water. 2. When the element is clean, rinse it thoroughly.
Important: Do not overfill the crankcase with oil and run the engine; engine damage may result. 11. Change the engine-oil filter; refer to Changing the Engine-oil Filter (page 26). Changing the Engine Oil 12. Slowly pour approximately 80% of the specified amount of oil into the fill hole (Figure 31). Service Interval: After the first 5 hours 13. Check the oil level; refer to Checking the Engine-oil Level (page 25). Every 100 hours (change it more often under a heavy load or in high temperatures). 14.
Checking the Spark Plug Servicing the Spark Plug 1. Inspect the spark plug (Figure 34). Service Interval: Every 50 hours—Check the spark plug. Note: If you see light brown or gray on the insulator, the engine is operating properly. A black coating on the insulator usually means that the air cleaner is dirty. Every 100 hours—Replace the spark plug. Ensure that the air gap between the center and side electrodes is correct before installing the spark plug.
Fuel System Maintenance 5. Remove the filter from the fuel lines. 6. Install a new filter with the flow direction arrow coming from the fuel tank and pointing to the engine. Note: Move the hose clamps close to the filter (Figure 35) to secure it in place. 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.
Electrical System Maintenance 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. WARNING • Always disconnect the negative (black) battery cable before disconnecting the positive (red) cable. 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.
Charging the Battery Servicing the Fuses Service Interval: Before storage—Charge the battery and disconnect battery cables. The electrical system is protected by fuses. It requires no maintenance; however, if a fuse blows, check the component/circuit for a malfunction or short. 1. Remove the battery from the chassis; refer to Removing the Battery (page 29). Fuse type: 2. Charge the battery for a minimum of 1 hour at 6 to 10 amps.
Releasing the Electric Brake Drive System Maintenance The electric brake releases by manually rotating the link arms forward. Once the electric brake is energized the brake will reset. Checking the Tire Pressure To release the brake: 1. Locate the shaft on the electric brake where the brake-link arms are connected (Figure 40). 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.
Cooling System Maintenance Mower Maintenance Cleaning the Engine Screen 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: Before each use or daily—Clean the engine air-intake screen. Check the cutter blades daily for sharpness, and for any wear or damage.
Inspecting the Blades 3. Measure from the tip of the blade to the flat surface (Figure 43). Service Interval: Before each use or daily—Check the cutting blades. 1. Inspect the cutting edges (Figure 41). Note: If the edges are not sharp or have nicks, remove and sharpen the blades; refer to Sharpening the Blades (page 34). 1 2. Inspect the blades, especially the curved area (Figure 41).
