Always Start Mowing with Sharp Blades A sharp blade cuts cleanly and without tearing or shredding the grass blades like a dull blade. Tearing and shredding causes the grass to turn brown at the edges which impairs growth and increases susceptibility to diseases. Make sure blade is in good condition and a full sail is present. Check Condition of Deck Make sure that the cutting chambers are in good condition. Straighten any bends in the chamber components to ensure the correct blade tip/chamber clearance.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval After the first hour Maintenance Procedure • Torque the wheel lug nuts to 70 to 90 ft-lb (94 to 122 N⋅m). After the first 8 hours • Check the condition and tension of the alternator belt. After the first 10 hours • Torque the wheel lug nuts to 70 to 90 ft-lb (94 to 122 N⋅m).

Engine Maintenance Servicing the Air Cleaner Check the air cleaner body for damage which could cause an air leak. Replace if damaged. Check the whole intake system for leaks, damage or loose hose clamps. Service the air cleaner filter only when the service indicator (Figure 38) requires it. Changing the air filter before it is necessary only increases the chance of dirt entering the engine when the filter is removed. Important: Be sure the cover is seated correctly and seals with the air cleaner body. 1.
3. Remove the oil filter (Figure 41). 3. Hold the injection pump lever arm against the high idle stop (Figure 42). 4. While pulling the throttle cable, to remove any slack, tighten the throttle cable connector. Note: When tightened, the cable pivot must be free to swivel on the injection pump lever arm. 5. If the throttle does not stay in position during operation, increase the torque on the locknut, used to set the friction device on the throttle lever. Figure 41 1. Oil filter 4.
Fuel System Maintenance DANGER Under certain conditions, diesel fuel and fuel vapors are highly flammable and explosive. A fire or explosion from fuel can burn you and others and can cause property damage. • Use a funnel and fill the fuel tank outdoors, in an open area, when the engine is off and is cold. Wipe up any fuel that spills. Figure 43 1. Water separator filter canister • Do not fill the fuel tank completely full. Add fuel to the fuel tank until the level is 1/4 to 1/2 in.
Electrical System Maintenance Important: Before welding on the machine, disconnect both cables from the battery, both wire harness plugs from the electronic control module, and the terminal connector from the alternator to prevent damage to the electrical system. Servicing the Battery Figure 44 WARNING 2. Turn the key in the key switch to the On position and watch the fuel flow around the connector. When you observe a solid flow of fuel, turn the key to the Off position.
