Product Overview Operation Controls Note: Determine the left and right sides of the machine from the normal operating position. Become familiar with the controls (Figure 4) before you start the engine and operate the machine. Adding Fuel 2 1 Use unleaded regular gasoline suitable for automotive use (87 pump octane minimum). You may use leaded, regular gasoline if unleaded gasoline is not available.
Using Stabilizer/Conditioner 1 Use a fuel stabilizer/conditioner in the traction unit to provide the following benefits: • It keeps gasoline fresh during storage of 90 days or less. For longer storage it is recommended that the fuel tank be drained. G015675 Figure 5 • It cleans the engine while it runs 1. Parking brake switch • It eliminates gum-like varnish buildup in the fuel system, which causes hard starting Note: The clutch/brake pedal should stay in the depressed (locked) position.

Operating Tips • For the best performance, operate the engine at the maximum speed. The mower requires air to thoroughly cut grass clippings, so do not set the height-of-cut too low or completely surround the mower in uncut grass. Always leave one side of the mower free from uncut grass to allow the air to be drawn into the mower. • Cut the grass slightly longer than normal to ensure that the cutting height of the mower does not scalp any uneven ground.
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. Check the engine oil level. Check the battery electrolyte level. Check the brake. Check the blades. Clean the mower housing. Every 25 hours • Grease and lubricate the machine.
Where to Add Grease 7. Wipe up any excess grease.
Removing the Foam and Paper Elements Cleaning the Foam and Paper Elements Foam Element 1. Clean around the air cleaner to prevent dirt from getting into the engine and causing damage. 1. Wash the foam element in liquid soap and warm water, and rinse it thoroughly. 2. Unscrew the knobs and remove the air cleaner cover (Figure 22). 2. Dry the element by squeezing it in a clean cloth. 3. Saturate the element in engine oil. 4. Squeeze the element in a clean, absorbent cloth to remove the excess oil.
13. Check the oil level again and add oil if necessary. Important: Do not overfill the crankcase with engine oil and run the engine; engine damage may result. Changing the Engine Oil Service Interval: After the first 5 hours Every 50 hours (Change the engine oil more frequently when operating the machine in extremely dusty or sandy conditions.) 1. Start the engine and let it run for 5 minutes. Figure 24 2. Checking the Engine Oil Level 3. 4. 5. 6. 7. 8. 9. Service Interval: Before each use or daily 1.
Servicing the Spark Plug 1. Drain the oil from the engine; refer to Changing the Engine Oil. Service Interval: Every 25 hours—Check the spark plug. 2. Remove the old filter and wipe off the adapter gasket surface (Figure 27). Every 100 hours—Replace the spark plug. Use a Champion RC12YC or equivalent spark plug. Ensure that the air gap between the center and side electrodes is 0.030 inch (0.76 mm) before installing the spark plug.
Fuel System Maintenance Draining the Fuel Tank Drain the fuel tank when you will not be using the machine for more than 30 days. Figure 29 1. Center electrode insulator 3. Air gap (not to scale) DANGER 2. Side electrode 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. Important: Do not clean the spark plug.
Electrical System Maintenance Note: Now is the best time to install a new fuel filter because the fuel tank is empty. 9. Install the fuel line onto the fuel filter. 10. Slide the hose clamp close to the fuel filter to secure both the fuel line and the fuel filter (Figure 30). Replacing the Headlight Bulbs 1. Disengage the blades (PTO). Replacing the Fuel Filter 2. Set the parking brake. Service Interval: Every 100 hours/Yearly (whichever comes first) 3.
Replacing the Fuses 4. Remove the ignition key. The electrical system is protected by fuses. They are located beneath the hood, near the fuel tank (Figure 34). If a fuse goes out, check the circuit wiring for a short. 5. Lift up the seat to see the battery. 1 6. Lift the rubber cover up off the negative (black) cable. 7. Disconnect the negative (black) ground cable from the battery post (Figure 35). 2 G012460 Figure 34 1.
4. Using the bolt and wing nut, connect the negative (black) cable to the negative (–) battery post (Figure 35). Slide the rubber cover over the battery post. 4. Replace the filler caps. Charging the Battery Checking the Electrolyte Level WARNING Service Interval: Before each use or daily Charging the battery produces gasses that can explode. Never smoke near the battery and keep sparks and flames away from the battery. 1. Tip the seat forward to see the battery. 2. Look at the side of the battery.
Checking the Brake Drive System Maintenance Service Interval: Before each use or daily 1. Park the machine on a level surface. 2. Disengage the blades (PTO). Checking the Tire Pressure 3. Set the parking brake. Service Interval: Every 25 hours/Yearly (whichever comes first) 4. Stop the engine and wait for all moving parts to stop. 5. Remove the ignition key. Maintain the air pressure in the front tires at 120 kPa and in the rear tires at 100 kPa. Check the pressure at the valve stem (Figure 37).
Cleaning the Grass Collector and Tunnel Servicing the Grass Collector 1. Disengage the blades (PTO). 2. Set the parking brake. Removing the Grass Collector 3. Stop the engine and wait for all moving parts to stop. 1. Lock the locking latch on the grass collector (Figure 39). 4. Remove the ignition key. 1 5.

Mower Deck Maintenance Removing the Blades 1. Remove the mower; refer to Removing the Mower. 2. Carefully tip the mower over. 3. Remove the bolts, washers, and blades (Figure 41). Wedge a block of wood between each blade and the mower to lock the blade when you are removing each bolt. Servicing the Blades Service Interval: Before each use or daily Note: Determine the left and right sides of the machine from the normal operating position. Note: The right blade has a left-hand threaded bolt. 4.
11. Remove the pin between the front arm linkage and the mower housing (Figure 45). 12. Remove the V-belt from the engine pulley (Figure 45). 13. Slide the mower out from beneath the machine. Installing the Mower Reverse the procedure for Removing the Mower. Figure 44 3. Tighten the blade bolts to 37 ft-lb (50 N-m). Removing the Mower 1. Park the machine on a level surface. 2. Disengage the blades (PTO). 3. Set the parking brake. 4. Stop the engine and wait for all moving parts to stop. 5.
Storage 13. Remove and inspect the spark plug; refer to Servicing the Spark Plug. With the spark plug removed from the engine, pour 2 tablespoons of engine oil into the spark plug hole. Use the electric starter to crank the engine and distribute the oil inside the cylinder. Install the spark plug, but do not connect the wire to the spark plug. 1. Disengage the blades (PTO). 2. Set the parking brake. 3. Stop the engine and wait for all moving parts to stop. 4. Remove the ignition key. 14.
Troubleshooting Problem The starter does not crank. The engine overheats. The machine does not drive. The engine will not start, starts hard, or fails to keep running. Possible Cause 1. The blade control (PTO) knob is engaged. 1. Move the blade control (PTO) knob to the Disengaged position. 2. The parking brake is not on. 3. The battery is dead. 4. The electrical connections are corroded or loose. 5. A fuse is blown. 6. A relay or switch is damaged. 2. Set the parking brake. 3. Charge the battery. 4.
