Preparation Safety • Evaluate the terrain to determine what accessories and This lawn mower meets or exceeds the CPSC blade safety requirements for walk-behind rotary lawn mowers and the B71.4 specifications of the American National Standards Institute in effect at the time of production. • Improperly using or maintaining this lawn mower can result in injury. To reduce the potential for injury, comply with these safety instructions.
• Look behind and down before backing up, to be sure of a clear path. • Be aware of the mower discharge direction and do not point it at anyone. • Do not operate the mower under the influence of alcohol or drugs. • Use care when loading or unloading the machine into a trailer or truck. • Use care when approaching blind corners, shrubs, trees, or other objects that may obscure vision. Maintenance and Storage • Wait for all movement to stop before adjusting, cleaning, or repairing.

Filling the Fuel Tank Operation DANGER Note: Determine the left and right sides of the machine from the normal operating position. Gasoline is extremely flammable and explosive. A fire or explosion from gasoline can burn you and others. Each time before you mow, make sure that the self-propel drive and the control bar operate properly. When you release the control bar, the blade and self-propel drive should stop. If they do not, contact an Authorized Service Dealer.
Figure 17 1. Ground speed control 5. Pull the recoil start handle lightly until you feel resistance, then pull it sharply. Allow the rope to return to the handle slowly. 6. When the engine starts, move the throttle control to the Fast position, and set the ground speed control as desired. Figure 15 1. Fuel tank cap Note: If the engine fails to start after 3 pulls, repeat steps 5 through 6. 2. Remove the fuel tank cap. 3.
Note: When grass is thick and lush, clippings may collect on and around the discharge tunnel plug. This may make removing the plug difficult. Clean the plug thoroughly after each use. Checking the Blade Brake Clutch Check the control bar before each use to ensure that the blade brake clutch system is operating properly. G019671 1 Figure 18 Normal Test 1. Raise the control bar to the handle. Service Interval: Before each use or daily 1. Stop the engine and wait for all moving parts to stop. 2.
9. Push the control bar to the right. 10. Lift the control bar up to about 1 inch (2.5 cm) below the handle; refer to position A in Figure 22. Note: The fan-like noise indicates that the blade is turning. Figure 24 Note: This intermediate position (C) is not the normal operating position of the control bar. However, it helps to detect a sticking blade brake clutch system early enough to prevent an unsafe condition later. 5. Release the control bar (Position B in Figure 24).
Installing the Grass Bag 1. Install the empty grass bag on the discharge tunnel. 2. Start the engine. 1. Stop the engine and wait for all moving parts to stop. 3. Push the control bar down to its lowest position. 2. Remove the discharge tunnel plug; refer to Using the Discharge Tunnel Plug (page 15). 4. Push the control bar to the right. 3. Ensure that the discharge door handle is fully forward (Figure 26). 5. Lift the control bar to the normal blade-engaged position about 1 inch (2.
Removing the Grass Bag • Mow only dry grass or leaves. Wet grass and leaves tend to clump on the yard and can cause the machine to plug or the engine to stall. 1. Stop the engine and wait for all moving parts to stop. 2. Raise the discharge door handle and move it forward so the pin clears the bag notch (Figure 26). WARNING 3. Grasp the handles at the front and the rear of the bag and lift the bag off the machine. Wet grass or leaves can cause serious injury if you slip and contact the blade. 4.
• Cut the grass more frequently. • Overlap cutting swaths instead of cutting a full swath with each pass. • Set the cutting height on the front wheels one notch lower than the rear wheels. For example, set the front wheels at 2-1/4 inches (57 mm) and the rear wheels at 2-3/4 inches (70 mm). Cutting Leaves • After cutting the lawn, ensure that half of the lawn shows through the cut leaf cover. You may need to make more than one pass over the leaves.
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 engine oil level. Check the operation of the blade brake clutch. Inspect the air cleaner elements. Inspect the blade for wear or damage. Clean under the machine housing.
Lubrication Engine Maintenance Lubricating the Pivot Arms Servicing the Air Cleaner Service Interval: Every 25 hours Service Interval: Before each use or daily—Inspect the air cleaner elements. Every 25 hours—Clean the air filter elements. Clean them more frequently in dusty operating conditions. Every 250 hours—Replace the air cleaner elements. Replace them more frequently in dusty operating conditions. 1. Move the rear wheel cutting height levers to the center setting. 2.
11. Wipe up any spilled oil. 9. Clean the foam element in warm, soapy water or in a nonflammable solvent. 12. Recycle the used oil according to local codes. Note: Do not use gasoline to clean the foam element because it could create a risk of fire or explosion. Servicing the Spark Plug 10. Rinse and dry the foam element thoroughly. Service Interval: Every 100 hours—Inspect and adjust the spark plug; replace it if necessary. 11.
Drive System Maintenance 1. Stop the engine and wait for all moving parts to stop. 2. Disconnect the wire from the spark plug. 3. Remove the bolt, the wheel spacer, and the locknut mounting the wheel to the pivot arm (Figure 34). Adjusting the Self-propel Drive Service Interval: Every 100 hours If the machine does not self-propel or has a tendency to creep forward when the control bar is more than 1-1/2 inches (3.8 cm) from the handle, adjust the wheel drive control knob on the rear of the gear box. 1.
Controls System Maintenance Blade Maintenance Adjusting the Blade Brake Cable Always mow with a sharp blade. A sharp blade cuts cleanly and without tearing or shredding the grass blades. Maintaining the Blade 1. Stop the engine and wait for all moving parts to stop. Service Interval: Every 100 hours 2. Disconnect the wire from the spark plug. Whenever you install a new blade brake cable assembly or replace the belt, adjust the blade brake cable. 3. Drain the gasoline from the fuel tank. 4.
Note: For the best performance, install a new blade before the cutting season begins. During the year, file down any small nicks to maintain the cutting edge. 2. If either end of the blade rotates downward, file that end (not the cutting edge or the end near the cutting edge). The blade is properly balanced when neither end drops.
Scraping Method Cleaning If washing does not remove all debris from under the machine, scrape it clean. Cleaning under the Machine Housing 1. Disconnect the wire from the spark plug. 2. Drain the fuel from the fuel tank. To ensure the best performance, keep the underside of the machine housing clean. Be especially careful to keep the kickers free of debris (Figure 40). WARNING Tipping the machine may cause the fuel to leak from the carburetor or the fuel tank.
Cleaning under the Belt Cover on the tabs (Figure 43). Rotate the tabs 180° to move them out of the way. Service Interval: Every 100 hours Keep the area under the belt cover free of debris. 1. Stop the engine and wait for all moving parts to stop. 2. Remove the bolts that secure the belt cover (Figure 42) to the machine housing. Figure 43 1. Tabs and nuts 2. Blade nuts 3. Blade brake clutch shield Figure 42 4. Tab and bolt 5. Blade 6. Accelerator 1. Belt cover 7.
Storage 4. Check the condition of the blade. Refer to Inspecting the Blade (page 24). To prepare the machine for off-season storage, perform the recommended maintenance procedures. Refer to Maintenance (page 20). 5. Clean the blade brake clutch shield; refer to Cleaning the Blade Brake Clutch Shield (page 27). 6. Service the air filter; refer to Servicing the Air Cleaner (page 21). Store the machine in a cool, clean, dry place. Cover the machine to keep it clean and protected. 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.
