Operation Note: Determine the left and right sides of the machine from the normal operating position. Each time before you mow, ensure that the self-propel drive and the blade-control bar operate properly. When you release the blade-control bar, the blade and the self-propel drive should stop. If they do not, contact an Authorized Service Dealer. CAUTION This machine produces sound levels in excess of 85 dBA at the operator's ear and can cause hearing loss through extended periods of exposure.
Adjusting the Cutting Height engine damage which may not be covered under warranty. • Do not use gasoline containing methanol. You can change the cutting height at each wheel by adjusting a cutting-height lever. Cutting heights are 25 mm (1 inch), 38 mm (1-1/2 inches), 51 mm (2 inches), 64 mm (2-1/2 inches), 76 mm (3 inches), 89 mm (3-1/2 inches), 102 mm (4 inches), 114 mm (4-1/2 inches). • Do not store fuel either in the fuel tank or in fuel containers over the winter unless you use a fuel stabilizer.
Operating the Self-Propel Drive and Engaging the Cutting Blade Starting the Engine 1. Connect the spark-plug wire to the spark plug. 2. Open the fuel valve (Figure 15). This machine is equipped with a blade-brake clutch. Important: To ensure that the blade-brake clutch is working properly, refer to Checking the Blade-Brake Clutch (page 14). The machine has 3 ground speeds: 1 (slow), 2 (medium), and 3 (fast). The self-propel-drive lever is located below and behind the fuel tank (Figure 16).
Checking without the Grass Bag 1. 2. 3. 4. g019672 Figure 18 1. Move the blade-control bar to the right. Move the machine onto a paved surface in a non-windy area. Set all 4 wheels to the 76 mm (3 inch) cutting-height setting; refer to Adjusting the Cutting Height (page 12). Take a half sheet of newspaper and crumple it into a ball small enough to go under the machine housing (about 76 mm or 3 inches in diameter). Place the newspaper ball about 13 cm (5 inches) in front of the machine (Figure 19). 2.
Installing the Grass Bag the rear-discharge chute until the latch locks into place (Figure 20). 1. Shut off the engine and wait for all moving parts to stop. 2. Raise and hold up the rear door (Figure 21). g024300 Figure 20 1. Rear-discharge plug 2. Rear door g024302 Figure 21 1. Rear door WARNING 3. Notch (2) 2. Bag-rod end (2) Operating the machine to recycle lawn clippings without the plug in place allows objects to be thrown toward you or bystanders.
Cutting Grass Operating Tips • Grass grows at different rates at different times of the year. In the summer heat, it is best to cut grass at the 64 mm (2-1/2 inch), 76 mm (3 inch), or 89 mm (3-1/2 inch) cutting-height settings. Cut only about a third of the grass blade at a time. Do not cut below the 64 mm (2-1/2 inch) setting unless the grass is sparse or it is late fall when grass growth begins to slow down.
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 8 hours • Change the engine oil and the oil filter. After the first 25 hours • Tighten any loose fasteners. Before each use or daily • • • • • Check the engine-oil level. Inspect the mower blades for wear or damage. Inspect the accelerator for wear or damage.
Engine Maintenance Servicing the Air Cleaner 8. Install the foam pre-cleaner and paper air filter onto the air-cleaner base. 9. Install the cover. Changing the Engine Oil Service Interval: Every 25 hours—Clean the foam pre-cleaner (more frequently in dusty conditions). Service Interval: After the first 8 hours Every 300 hours—Replace the paper air filter (more frequently in dusty conditions).
Changing the Engine-Oil Filter Service Interval: Every 200 hours 1. Run the engine to warm the oil. WARNING Oil may be hot after the engine has been run, and contact with hot oil can cause severe personal injury. g002805 Figure 24 Avoid contacting the hot engine oil when you drain it. 2. Shut off the engine and wait for all moving parts to stop. 3. Disconnect the wire from the spark plug. 4. Drain the gasoline from the fuel tank. 5.
Servicing the Spark Plug Drive System Maintenance Service Interval: Every 100 hours—Inspect, clean, and adjust the spark plug gap; replace the spark plug if necessary. Adjusting the Self-Propel Drive Use an NGK BPR5ES spark plug or equivalent. 1. Shut off the engine and wait for all moving parts to stop. 2. Disconnect the wire from the spark plug. 3. Clean around the spark plug. 4. Remove the spark plug from the cylinder head.
8. Brake Maintenance For a new traction belt, rotate the drive cable adjustment knob clockwise 1 additional turn to allow for the normal stretching of the belt during the break-in period. Adjusting the Blade-Brake Cable Note: You can skip this step if you are adjusting a used belt. If the blade brake cable needs to be replaced or is not adjusted properly, adjust the blade brake cable. 1. Shut off the engine and wait for all moving parts to stop. 2. Disconnect the wire from the spark plug. 3.
Blade Maintenance Maintaining the Blade Always mow with a sharp blade. A sharp blade cuts cleanly and without tearing or shredding the grass blades. 1. Shut off the engine and wait for all moving parts to stop. g002278 Figure 29 2. Disconnect the wire from the spark plug. 3. Close the fuel valve by moving the fuel-valve lever to the left (Figure 15). 4. Drain the gasoline from the fuel tank. 5. Tip the machine onto its right side (air cleaner up) as shown in Figure 28. 1. Sail 2.
Balancing the Blade WARNING 1. A worn or damaged accelerator can break, and a piece of the accelerator could be thrown toward you or bystanders, resulting in serious personal injury or death. Check the balance of the blade by placing the center hole of the blade over a nail or screwdriver shank clamped horizontally in a vise (Figure 32). • Inspect the accelerator periodically for wear or damage. • Replace a worn or damaged accelerator. Removing the Blade g002280 Figure 32 1.
2. greater than 8 mm (5/16 inch), the belt will not properly drive the blade. Install the new blade-brake cable, but do not tighten the cable clamp on the top of the mower housing (Figure 33). g024466 3. 2. Cable clamp and screw Insert a 8 mm (5/16-inch) thick spacer between the blade-brake-control lever and the control bracket on the handle (Figure 34). g024467 Figure 34 1. Handle 2.
Cleaning Note: The blade will draw in water and wash out the clippings. Let the water run until you no longer see clippings being washed out from under the machine. Cleaning under the Machine To ensure the best performance, keep the underside of the machine clean. Be especially careful to keep the kickers free of debris (Figure 35). 4. Shut off the engine and wait for all moving parts to stop. 5. Turn off the water. 6.
Cleaning under the Belt Cover WARNING Tipping the machine may cause the fuel to leak from the carburetor or the fuel tank. Gasoline is extremely flammable, highly explosive, and, under certain conditions, can cause personal injury or property damage. Service Interval: Every 50 hours—Remove grass clippings and debris from under the belt cover. 1. Shut off the engine and wait for all moving parts to stop. 2. Disconnect the wire from the spark plug. 3.
Storage To prepare the machine for off-season storage, perform the recommended maintenance procedures; refer to Maintenance (page 17)d. Store the machine in a cool, clean, dry place. Cover the machine to keep it clean and protected. Preparing the Fuel System WARNING Gasoline can vaporize if you store it over long periods of time and explode if it comes into contact with an open flame. • Do not store gasoline over long periods of time.
2. Clean any dirt and chaff from the cylinder, cylinder head fins, and blower housing. 3. Remove grass clippings, dirt, and grime from the external parts of the engine, the shrouding, and the top of the mower housing. 4. Check the condition of the blade; refer to Inspecting the Blade (page 22). 5. Clean the blade-brake-clutch shield; refer to Cleaning the Blade-Brake-Clutch Shield (page 26). 6. Service the air cleaner; refer to Servicing the Air Cleaner (page 18). 7.
Troubleshooting Problem The engine does not start. The engine starts hard or loses power. Possible Cause 1. The fuel tank is empty or the fuel system contains stale fuel. 1. Drain and/or fill the fuel tank with fresh gasoline. If the problem persists, contact an Authorized Service Dealer. 2. The throttle lever is not in the Choke position. 3. The wire is not connected to the spark plug. 4. The spark plug is pitted, fouled, or the gap is incorrect. 2. Move the throttle lever to the Choke position. 3.
