Operation Note: Determine the left and right sides of the machine from the normal operating position. Each time before you mow, make sure that the self-propel drive and the blade control bar operate properly. When you release the blade control bar, the blade and self-propel drive should stop. If they do not, contact an Authorized Service Dealer. Figure 11 1. Dipstick 2.
Filling the Fuel Tank with Gasoline 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. For best results, use clean, fresh, lead-free gasoline with an octane rating of 87 or higher. To ensure freshness, purchase only the quantity of gasoline that you expect to use in 30 days. Using unleaded gasoline results in fewer combustion deposits and longer engine life.

If the blade brake clutch system is inoperative, the blade will continue to rotate when you release the blade control bar. Contact with blade could occur, causing serious injury. Figure 20 • Check the blade brake clutch system operation before each use. • Never use a lawn mower equipped with a blade brake clutch that has an inoperative safety system. Note: This intermediate position (C) is not the normal operating position of the blade control bar.
Adjusting the Cutting Height 2. Ensure that the discharge door handle is fully forward and that the pin is engaged in the catch (Figure 22). Each wheel is adjusted individually with a wheel height adjustment lever. Cutting heights are 1 inch (25 mm), 1-1/2 inches (38 mm), 2 inches (51 mm), 2-1/2 inches (64 mm), 3 inches (76 mm), and 3-1/2 inches (89 mm). Adjusting the cutting height levers could bring your hands into contact with a moving blade and result in serious injury.
Operating Tips Mowing with the Grass Bag General Tips 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. • Review the safety instructions and read this manual carefully before operating the lawn mower. • Clear the area of sticks, stones, wire, branches, and other debris that the blade could hit and throw. Check the grass bag frequently.
set the front wheels at 2 inches (51 mm) and the rear wheels at 2-1/2 inches (64 mm). Operating a lawn mower with its engine running at a speed greater than the factory setting can cause the lawn mower to throw a part of the blade or engine into the operator’s or bystander’s area and result in serious personal injury or death. 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 rst 8 operating hours • Change the engine oil without the oil lter. Before each use or daily • • • • • Check the engine oil level. Check the operation of the blade brake clutch. Inspect the mower blades for wear or damage. Clean under the lawn mower housing. Clean the discharge tunnel and plug.
Important: Do not operate the engine without the air filter assembly; extreme engine damage will occur. 1. Stop the engine and wait for all moving parts to stop. 2. Disconnect the wire from the spark plug (Figure 13). 3. Remove the screw that secures the air cleaner cover (Figure 26). Figure 24 1. Grease tting 3. Install a grease gun onto the fitting and gently apply 2 or 3 pumps of #2 multi-purpose lithium-base grease. Important: Excessive grease pressure may damage the seals.
Changing the Oil Filter 7. Saturate the pre-cleaner with oil, then squeeze it (do not twist) to remove the excess oil. Replace the oil filter (Figure 28) after every 100 operating hours or yearly, whichever comes first. 8. Install the foam pre-cleaner. 9. Install the paper air filter. Note: Install a new paper air filter if you discarded the old one. 10. Install the cover and secure it with the screw.
8. Install the new filter and hand tighten it 2/3 turn only. 9. Fill the crankcase to the Full line on the dipstick with fresh oil Refer to Filling the Crankcase with Oil. 10. Connect the wire to the spark plug. 11. Run the engine for about 3 minutes. 12. Stop the engine, wait for all moving parts to stop, and check for oil leakage around the filter. 13. Add oil to compensate for the oil in the oil filter. Refer to Checking the Engine Oil Level. 14. Recycle the used oil filter according to local codes.
Fuel System Maintenance Emptying the Fuel Tank and Cleaning the Fuel Filter The fuel filter (screen) element is located inside the fuel tank. Clean the fuel filter element every 100 operating hours. Figure 31 1. Stop the engine and wait for it to cool down. Note: Drain gasoline from a cold engine only. 1. 2. Disconnect the wire from the spark plug (Figure 13). Control knob 3. Slowly pull the lawn mower backward while you gradually move the control bar toward the handle. 3.
Controls System Maintenance Adjusting the Blade Brake Cable Whenever you install a new blade brake cable assembly or replace the belt, adjust the blade brake cable. 1. Stop the engine and wait for all moving parts to stop. 2. Disconnect the wire from the spark plug (Figure 13). 3. Loosen the cable clamp screw until the brake cable conduit slides (Figure 34). Figure 33 1. Locknuts 6. 2. 3. 4. 5. 7. 8. 9.
Blade Maintenance Maintaining the Cutting Blade Always mow with a sharp blade. A sharp blade cuts cleanly and without tearing or shredding the grass blades. 1. Stop the engine and wait for all moving parts to stop. Figure 36 1. 2. 2. Disconnect the wire from the spark plug (Figure 13). Sail Flat part of the blade 3. 4. Wear Slot formed 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. 3.
Balancing the Blade 1. Check the balance of the blade by placing the center hole of the blade over a nail or screwdriver shank clamped horizontally in a vise (Figure 38). especially careful to keep the kickers free of debris (Figure 39). Figure 38 Figure 39 Note: You can also check the balance using a commercially manufactured blade balancer. 2. If either end of the blade rotates downward, file that end (not the cutting edge or the end near the cutting edge).
1. Disconnect the wire from the spark plug (Figure 13). Grass clippings and other objects can be thrown from an open discharge tunnel and cause serious injury or kill the operator or bystanders. 2. Drain the fuel from the fuel tank. Refer to Emptying the Fuel Tank and Cleaning the Fuel Filter. Never start or operate the lawn mower unless one of the following is true: Tipping the lawn mower may cause the fuel to leak from the carburetor or the fuel tank.
6. Loosen the tabs that secure the blade brake clutch shield to the deck by loosening the nuts or the bolts on the tabs (Figure 41). Rotate the tabs 180° to move them out of the way. Figure 42 1. Belt cover 3. Lift off the cover and brush out all the debris around the belt area. Figure 41 1. Tabs and nuts 2. Blade brake clutch shield 3. 4. Install the belt cover. Tab and bolt 7.
