3. Push the plug all the way in until the spring clip on the bottom of the plug clicks into place, locking the plug securely into the discharge tunnel (Fig. 5). To add oil: 1. Move the lawn mower to a level surface. 2. Clean around the dipstick (Fig. 6). 3. Remove the dipstick by rotating the cap counterclockwise and pulling it out. 1 4. Wipe the dipstick clean with a clean cloth. 5. Insert the dipstick into the filler neck (but do not rotate the cap clockwise to secure it), then remove it. 6.
1. Clean around the fuel tank cap (Fig. 7). Danger 1 2 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 • Fill the fuel tank outdoors, in an open area, and when the engine is cold. Wipe up any gasoline that spills. • Do not fill the fuel tank completely full. Add gasoline to the fuel tank until the level is 1/4 to 1/2 inch (6 to 13 mm) below the bottom of the filler neck.
Operation 3. Move the throttle control to the Choke position (Fig. 8). Note: Do not use the choke when the engine is warm. Note: Determine the left and right sides of the machine from the normal operating position. 4. Hold the control bar to the handle (Fig. 8). Each time before you mow, ensure that the self-propel drive and the control bar operate properly. When you release the control bar, the engine and the blade should stop within 3 seconds. If they do not, contact an Authorized Service Dealer. 5.
Checking the Blade Brake Clutch 3. Squeeze the control bar against the handle to the Run/Drive position (Fig. 11). 1 Check the blade control bail before each use to ensure that the blade brake clutch (BBC) system is operating properly. 2 3 Normal Test 1. Stop the engine and wait for all moving parts to stop. 2. Move the lawn mower onto a paved surface in a non-windy area. m-3769 Figure 11 1. Run/Drive position 2. Run/Shift position 3.
3. Bring the blade control bail up into the middle position about 5 inches (12.7 cm) below the handle cross bar (Position C in Fig. 16). 9. Lift the blade control bail up to about one inch (2.5 cm) below the handle; refer to position A in Figure 14. Note: The fan-like noise indicates that the lawn mower blade is turning. 1 C A B m-5086 Figure 16 B m-5085 Note: This intermediate position (C) is not the normal operating position of the blade control bail.
Test Using the Grass Bag 3. Adjust all the wheels to the same cutting height setting. You can use the grass bag to perform an additional test to check the blade brake clutch mechanism: Using the Grass Bag 1. Install the empty grass bag on the discharge tunnel. Occasionally, you may want to use the grass bag for bagging extra long grass, lush grass, or leaves. 2. Start the engine. 3. Push the blade control bail (Fig. 13) down to its lowest position. Installing the Grass Bag 4.
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 18. • 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 3. Attach the coupling to the washout fitting (Fig. 21). Before you use the lawn mower, ensure that the oil level is between the lower limit and the upper limit marks as shown on the dipstick (Fig.
Servicing the Air Cleaner Warning Inspect the air cleaner elements after every time you use the lawn mower. Tipping the lawn mower 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. Clean the cover, base, and foam and paper elements after every 25 operating hours.
9. Clean the foam element in warm, soapy water or in a nonflammable solvent. the blade, check the blade before using the lawn mower. If you notice a slot or wear (Figs. 24B and 24C), replace the blade; refer to Removing the Blade on page 20. Note: Do not use gasoline to clean the foam element because it could create a risk of fire or explosion. 1 10. Rinse and dry the foam element thoroughly. A 11. Dip the foam element in clean engine oil, then squeeze out the excess oil.
Sharpening the Blade 3. Connect the wire to the spark plug. File the top side of the blade to maintain its original cutting angle (Fig. 25A) and inner cutting edge radius (Fig. 25B). The blade will remain balanced if you remove the same amount of material from both cutting edges. Cleaning the Blade Brake Clutch Shield A B 1 Clean the BBC (blade brake clutch) shield at the end of each mowing season to ensure the best performance and to prevent parts from degrading.
9. Install the blade, the accelerator, the anti-scalp cup, and the 2 blade nuts. 3. Install a grease gun onto the fitting and gently apply 2 or 3 pumps of #2 multi-purpose lithium base grease (Fig. 29). 10. Turn the lawn mower upright. 11. Connect the wire to the spark plug. Note: Applying grease with excessive pressure may damage the seals. Cleaning under the Belt Cover Adjusting the Self-propel Drive Keep the area under the belt cover free of debris.
Note: Warm oil flows better and carries more contaminants. 1 Warning m-110 Oil may be hot after engine has been run, and contact with hot oil can cause severe personal injury. Figure 32 1. 0.030 inch (0.76 mm) Avoid contacting the hot engine oil when you drain it. 6. Carefully install the spark plug by hand (to avoid cross threading) until it is hand tight. 2.
