Before Starting Important Do not overfill the crankcase with oil and run the engine; engine damage will result. Drain the excess oil until the oil level reaches the upper limit mark on the dipstick. Filling the Crankcase with Oil 8. Insert the dipstick into the filler neck and rotate the cap clockwise until it is tight. The engine crankcase can hold 22 ounces (0.65 liters) of oil.
3. Fill the fuel tank with unleaded gasoline to within 1/4 to 1/2 inch (6 to 13 mm) from the top of the tank. Do not fill into the filler neck. Danger When fueling, under certain circumstances, a static charge can develop, igniting the gasoline. A fire or explosion from gasoline can burn you and others and damage property. Note: The fuel tank capacity is 2.1 qt. (2.0 L). 4. Install the fuel tank cap and wipe up any spilled gasoline.
Operation 3. Move the throttle control to the Choke position (Fig. 7). 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. 7). 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. 10). 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 10 1. Run/Drive position 2. Run/Shift position 3. Set all 4 wheels in to the 2-1/2 in.
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. 15). 9. Lift the blade control bail up to about one inch (2.5 cm) below the handle; refer to position A in Figure 13. Note: The fan-like noise indicates that the lawn mower blade is turning. 1 C A B m-5086 Figure 15 B m-5085 Note: This intermediate position (C) is not the normal operating position of the blade control bail.
Test Using the Grass Bag 2. Release the wheel height adjustment lever and seat it securely in the notch. You can use the grass bag to perform an additional test to check the blade brake clutch mechanism: 3. Adjust all the wheels to the same cutting height setting. 1. Install the empty grass bag on the discharge tunnel. 2. Start the engine. Using the Grass Bag 3. Push the blade control bail (Fig. 12) down to its lowest position.
Mowing with the Grass Bag Operating Tips • Review the safety instructions and read this manual carefully before operating the lawn mower. Warning • Clear the area of sticks, stones, wire, branches, and other debris that the blade could hit and throw. 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.
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 3. Hold the running water at handle level and direct the water to flow on the ground just in front of the right rear tire (Fig. 20).
3. Remove the 2 wing bolts that secure the cover (Fig. 21). 4. Remove the dirt and grass clippings with a hardwood scraper. Avoid burrs and sharp edges. 1 5. Return the lawn mower to the operating position. 6. Fill the fuel tank with fresh gasoline. 7. Connect the wire to the spark plug. 2 Cleaning the Discharge Tunnel and Plug 3 4 Remove the plug from the discharge tunnel and clean it after each use. 5 Always ensure that the discharge tunnel door closes securely when you release the handle.
Inspecting the Blade 12. Wipe dirt from the base and the cover with a moist rag. Carefully examine the blade for sharpness and wear, especially where the flat and the curved parts meet (Fig. 23A). Because sand and abrasive material can wear away the metal that connects the flat and curved parts of the blade, check the blade before using the lawn mower. If you notice a slot or wear (Figs. 23B and 23C), replace the blade; refer to Removing the Blade on page 19.
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. 24A) and inner cutting edge radius (Fig. 24B). 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. Lubricating the Pivot Arms 10. Turn the lawn mower upright. After every 25 operating hours or when the season ends, lubricate the pivot arms. 11. Connect the wire to the spark plug. 1. Move the rear wheel cutting height levers to the center setting. Cleaning under the Belt Cover 2. Wipe the grease fittings with a clean rag (Fig. 28). Keep the area under the belt cover free of debris. 1.
12. Connect the wire to the spark plug. 3. Slowly pull the lawn mower rearward while you gradually move the control bar toward the handle. 13. Recycle the used oil according to local codes. Note: The adjustment is correct when the rear wheels stop turning and the control bar is about one inch (2.5 cm) from the handle (Fig. 30). Servicing the Spark Plug Check the spark plug after every 100 operating hours or yearly; replace it after every 250 operating hours or every 2 years.
Lubricating the Gear Case Warning After every 100 operating hours, grease the gear case. Do not overtighten the blade brake cable. Overtightening the blade brake cable could cause the blade brake to come off of the brake drum. If the brake does not contact the drum, the blade will not stop rotating when you release the control bar. A rotating blade could cause serious personal injury. 1. Remove the grass bag. 2. Install a grease gun onto the fitting through the belt cover opening (Fig. 32).
Assembling the Wheels Warning 1. Position the tire onto one wheel half, aligning the lugs on each (Fig. 34). 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. 34). • 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: 7.
