7. If the oil level reading is below the Add mark on the dipstick, slowly pour only enough oil into the filler hole to raise the oil level to the Full mark on the dipstick. Before Starting Filling the Crankcase with Oil Important Do not overfill the crankcase with oil and run the engine; engine damage will result. Drain the excess oil until the oil level on the dipstick reads Full. The crankcase can hold 20 ounces (0.59 liters) of oil.
Operation Danger Note: Determine the left and right sides of the machine from the normal operating position. 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. Each time before you mow, ensure that the self-propel drive (self-propel model only) and the blade control bail operate properly. When you release the blade control bail, the engine and the self-propel drive should stop.
Adjusting the Cutting Height 3. Hold the blade control bail against the upper handle (Fig. 8). 2 The SmartWheel has 2 cutting scales: Sparse/Normal and Lush—to ensure the best cutting height setting in any mowing condition (Fig. 12). Use the Sparse/Normal scale during the warm summer season for the majority of your mowing. The Lush scale is for thick, moist, and succulent grass that grows most often in the spring. 1 3 m-4207 Figure 10 1. Blade control bail 2. Upper handle 3. Starter handle 4.
Using the Grass Bag 3. Use the SmartWheel design to compare the tips of the grass blades to the letters on the wheel. The letter on the SmartWheel that matches the tips of the grass blades is the proper cutting height. Occasionally, you may want to use the grass bag for bagging lush grass or collecting leaves. 4. Squeeze the cutting height lever toward the wheel and move it to the corresponding letter on the lawn mower housing (Fig. 13). Installing the Grass Bag 1.
• Avoid striking trees, walls, curbs, or other solid objects. Never deliberately mow over any object. Mowing with the Grass Bag • If the lawn mower strikes an object or starts to vibrate, immediately stop the engine, disconnect the wire from the spark plug, and examine the lawn mower for damage. Warning 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.
• When cutting grass over 6 inches (15 cm) tall, first mow at the highest cutting height setting and walk slower; then mow again at a lower setting for the best lawn appearance. If the grass is too long and the leaves clump on top of the lawn, the lawn mower may plug and cause the engine to stall. • Alternate the mowing direction. This helps disperse the clippings over the lawn for even fertilization. If the finished lawn appearance is unsatisfactory, try one or more of the following: • Sharpen the blade.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule Each Use 5 Hours • Check the blade and the engine mounting fasteners. Tighten them if they are loose. 25 Hours • Replace the air filter; replace it more frequently in dusty or dirty operating conditions. Refer to Replacing the Air Filter on page 16. • Inspect the spark plug and replace it if necessary. Refer to Servicing the Spark Plug on page 17.
Checking the Engine Oil Level Before you use the lawn mower, ensure that the oil level is between the Add and the Full marks as shown on the dipstick (Fig. 7). If the oil level is below the Add mark, add oil. Refer to Filling the Crankcase with Oil on page 18. 1 2 Cleaning the Underside of the Lawn Mower Housing Keep the underside of the lawn mower housing clean. Be especially careful to keep the kickers free of debris (Fig. 16). m-3044 Figure 17 1 1. Washout fitting 2. Hose 4.
Scraping Method 1. Stop the engine and wait for all moving parts to stop. 2. Disconnect the wire from the spark plug (Fig. 7). Warning 3. Loosen the screw that secures the air filter cover to the engine (Fig. 18). 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.
Servicing the Spark Plug 4. Push the drive bracket down until it contacts the lawn mower, then hold it in place (Fig. 21). Check the spark plug after every 25 operating hours. Use a Champion RJ19LM spark plug or equivalent. 2 1 1. Stop the engine and wait for all moving parts to stop. 2. Disconnect the wire from the spark plug (Fig. 7). 3. Clean around the spark plug and remove it from the cylinder head. m-4273 Important Replace a cracked, fouled, or dirty spark plug.
Changing the Engine Oil Warning Change the oil after the first 5 operating hours and then after every 50 hours or every season. Run the engine just before changing the oil to warm the oil. Warm oil flows better and carries more contaminants. The blade is sharp; contacting the blade can result in serious personal injury. Wear gloves or wrap the sharp edges of the blade with a rag. Note: Change the oil after every 25 hours when operating under a heavy load or in high temperatures. 1. Remove the grass bag.
Sharpening the Blade blade, check the blade before using the lawn mower. If you notice a slot or wear (Figs. 25B and 25C), replace the blade; refer to Removing the Blade on page 19. 1 File the top side of the blade to maintain its original cutting angle (Fig. 26A) and inner cutting edge radius (Fig. 26B). The blade will remain balanced if you remove the same amount of material from both cutting edges. A A 2 1 B 1 2 m 4783 153 B Figure 26 1 3 1. Sharpen at this angle only 2.
Cleaning Under the Belt Cover Storage Keep the area under the belt cover free of debris. To prepare the lawn mower for off-season storage, perform the recommended maintenance procedures. Refer to Maintenance on page 14. 1. Stop the engine and wait for all moving parts to stop. 2. Remove the bolts that secure the belt cover to the lawn mower housing (Fig. 28).
