To add oil: Danger 1. Move the lawn mower to a level surface. 2. Clean around the dipstick (Fig. 6). 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. 3. Remove the dipstick by rotating the cap counterclockwise and pulling it out. 4. Wipe the dipstick clean with a clean cloth. • Fill the fuel tank outdoors, in an open area, and when the engine is cold. Wipe up any gasoline that spills.
Use a fuel stabilizer/conditioner regularly during operation and storage. A fuel stabilizer/conditioner cleans the engine during operation and prevents gum-like varnish deposits from forming in the engine during periods of storage. Operation Important Do not use fuel additives other than a fuel stabilizer/conditioner . Do not use fuel stabilizers with an alcohol base such as ethanol, methanol, or isopropanol.
Starting the Engine Using the Self-propel Drive 1. Connect the wire to the spark plug (Fig. 7). Self-propel Model only 2. Open the fuel valve by moving the lever to the right (Fig. 9). The lawn mower has three ground speeds. 1 is slow, 2 is medium, and 3 is fast. The ground speed control is located at the rear of the belt cover (Fig. 10). 1 Figure 9 1. Fuel valve 1 224 Figure 10 3. Move the throttle control to the Choke position (Fig. 8). 1.
3. Adjust all the wheels to the same cutting height setting. ground speed. Move the ground speed control to the Neutral position when you use the lawn mower for trimming or whenever you leave the lawn mower. Using the Grass Bag Using the Discharge Tunnel Plug Occasionally, you may want to use the grass bag for bagging extra long grass, lush grass, or leaves. 1. Stop the engine and wait for all moving parts to stop. Installing the Grass Bag 2.
Operating Tips Mowing with the Grass Bag Warning • Review the safety instructions and read this manual carefully before operating the lawn mower. A worn grass bag could allow small stones and other similar debris to be thrown in the operator’s or bystander’s direction and result in serious personal injury or death to the operator or bystanders. • Clear the area of sticks, stones, wire, branches, and other debris that the blade could hit and throw.
Cutting Grass • Grass grows at different rates at different times of the year. In the summer heat, it is best to cut grass at the 2-1/4-inch (5.7 cm), 2-3/4-inch (7.0 cm), or 3-1/4-inch (8.3 cm) cutting height settings. Cut only about a third of the grass blade at a time. Do not cut below the 2-1/4-inch (5.7 cm) 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 Maintenance Service Interval Each Use Maintenance Procedure • Check the engine oil level. Refer to Checking the Engine Oil Level on page 17. • Check the stopping time of the blade brake. The blade must stop within 3 seconds of releasing the control bar; if it does not, contact an Authorized Service Dealer for repair.
Caution If you leave the wire on the spark plug, someone could accidently start the engine and seriously injure you or other bystanders. Disconnect the wire from the spark plug before you do any maintenance. Set the wire aside so that it does not accidently contact the spark plug. Checking the Engine Oil Level Note: The water will splash into the blade and clean out the clippings. Let the water run until you no longer see clippings being washed out from under the housing.
Cleaning the Discharge Tunnel and Plug 1 2 Remove the plug from the discharge tunnel and clean it after each use. Always ensure that the discharge tunnel door closes securely when you release the handle. If the debris prevents the discharge door from closing securely, clean the inside of the discharge tunnel and the door thoroughly. 3 4 5 Warning Grass clippings and other objects can be thrown from an open discharge tunnel and cause serious injury or kill the operator or bystanders.
Maintaining the Blade Danger Always mow with a sharp blade. A sharp blade cuts cleanly and without tearing or shredding the grass blades. A worn or damaged blade can break, and a piece of the blade could be thrown into the operator’s or bystander’s area, resulting in serious personal injury or death. 1. Stop the engine and wait for all moving parts to stop. 2. Disconnect the wire from the spark plug (Fig. 7). 3. Drain the gasoline from the fuel tank. • Inspect the blade periodically for wear or damage.
Lubricating the Pivot Arms 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. Self-propel Model only After every 25 operating hours or when the season ends, lubricate the pivot arms. Installing the Blade 1. Move the rear wheel cutting height levers to the center setting. 1. Install a sharp, balanced Toro blade, the accelerator, the lock washer, and the blade bolt.
Adjusting the Self-propel Drive Changing the Engine Oil Self-propel Model only Change the oil after the first 8 operating hours (or the first month); and then after every 100 operating hours (or every 6 months). If the lawn mower 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 (Fig. 24). 1. Run the engine to warm the engine oil.
Servicing the Spark Plug Lubricating the Gear Case Check the spark plug after every 100 operating hours or yearly; replace it after every 250 operating hours or every 2 years. Use an NGK) BPR5ES or Nippondenso) W16EPR-U spark plug or equivalent. Self-propel Model only 1. Stop the engine and wait for all moving parts to stop. 2. Install a grease gun onto the fitting through the belt cover opening (Fig. 27). After every 100 operating hours, grease the gear case. 1. Remove the grass bag. 2.
Adjusting the Blade Brake Cable 1 Whenever you install a new blade brake cable assembly, adjust it. 1. Stop the engine and wait for all moving parts to stop. 2 2. Disconnect the wire from the spark plug (Fig. 7). 3. Check the adjustment of the cable by moving the control bar toward the handle until you remove the slack in the cable. The gap between the brake lever and the handle must be between 3/16 and 1/4 in. (5 and 6 mm). To adjust the cable, go to step 4. 3. 3/16 to 1/4 in. (5 to 6 mm) 4.
Assembling the Wheels Warning 1. Position the tire onto one wheel half, aligning the lugs on each (Fig. 30). Gasoline can vaporize if you store it over long periods of time and explode if it comes into contact with an open flame. 2. Place the bearing/hub assembly into the center hole of the wheel half. Ensure that the legs of the hub are positioned over the flange of the hole (Fig. 30). • Do not store gasoline over long periods of time.
Removing the Lawn Mower from Storage 6. Fill the fuel in the fuel tank with fresh gasoline. 1. Check and tighten all fasteners. 8. Connect the wire to the spark plug. 2. Remove the spark plug and spin the engine rapidly using the starter to blow the excess oil from the cylinder. Accessories 3. Clean the spark plug or replace it if it is cracked, broken, or if the electrodes are worn. You may purchase the following accessories from an Authorized Service Dealer: 4. Install the spark plug.
Problem Engine runs rough Lawn mower or engine vibrates excessively Uneven cutting pattern Discharge chute plugs Lawn mower does not self-propel (Self-propel model only) Possible Causes Corrective Action 1. The wire is not connected to the spark plug. 1. Connect the wire to the spark plug. 2. The spark plug is pitted, fouled, or the gap is incorrect. 2. Check the spark plug and adjust the gap if necessary. Replace the spark plug if it is pitted, fouled, or cracked. 3.
