Product Overview 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 control bar operate properly. When you release the control bar, the blade, the engine, and the self-propel drive should stop. If they do not, contact an Authorized Service Dealer. This machine produces sound levels in excess of 85dBA at the operator’s ear and can cause hearing loss through extended periods of exposure.
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. You may use leaded gasoline if unleaded gasoline is not available. Important: Do not add oil to the gasoline. Important: Do not use methanol, gasoline containing methanol, gasohol containing more than 10% ethanol, premium gasoline, or white gas. Using these fuels can damage the engine’s fuel system.
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. • Always place gasoline containers on the ground and away from your vehicle before filling. • Do not fill gasoline containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.

This may make removing the plug difficult. Clean the plug thoroughly after each use. Adjusting the Cutting Height Each wheel is adjusted individually with a wheel height adjustment lever. Cutting heights are 3/4 inch (19 mm), 1-1/4 inches (32 mm), 1-3/4 inches (44 mm), 2-1/4 inches (57 mm), 2-3/4 inches (70 mm), and 3-1/4 inches (83 mm). Figure 17 1. Bag frame on retaining post 2.
Mowing with the Grass Bag Operating Tips General Tips • 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 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. 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. • For light leaf coverage, set all the wheels at the same cutting height setting.
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 first 8 hours • Change the engine oil without the oil filter. Before each use or daily • • • • • Check the engine oil level. Ensure that the engine stops within 3 seconds after releasing the control bar. Inspect the mower blades for wear or damage. Clean under the lawn mower housing.
Lubrication Engine Maintenance Lubricating the Pivot Arms Servicing the Air Filter Service Interval: Every 25 hours Service Interval: Every 25 hours—Clean the foam pre-cleaner (more frequently in dusty conditions). Every 300 hours—Replace the paper air filter (more frequently in dusty conditions). 1. Move the rear wheel cutting height levers to the center setting. 2. Wipe the grease fittings with a clean rag (Figure 19).
4. Drain the engine oil; refer to Changing the Engine Oil. Every 50 hours—Change the engine oil (more often in dusty conditions). 1. Run the engine to warm the engine oil. 5. Place a rag under the oil filter to catch any oil that may leak out as you remove the filter. Note: Warm oil flows better and carries more contaminants. 6. Remove the oil filter (Figure 22). Oil may be hot after engine has been run, and contact with hot oil can cause severe personal injury.
Servicing the Spark Plug Fuel System Maintenance Service Interval: Every 100 hours—Check the spark plug. Use an NGK BPR5ES spark plug or equivalent. Emptying the Fuel Tank and Cleaning the Fuel Filter 1. Stop the engine and wait for all moving parts to stop. 2. Disconnect the wire from the spark plug (Figure 12). Service Interval: Every 50 hours—Check the fuel hose and replace it if necessary. 3. Clean around the spark plug. 4. Remove the spark plug from the cylinder head.
Drive System Maintenance Controls System Maintenance Adjusting the Self-propel Drive Adjusting the Blade Brake Cable Service Interval: Every 100 hours Service Interval: Every 100 hours 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. Whenever you install a new blade brake cable assembly, adjust it. 1.
Blade Maintenance 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. 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. 2. Disconnect the wire from the spark plug (Figure 12). 3.
Cleaning 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). The blade is properly balanced when neither end drops. Cleaning under the Lawn Mower Housing To ensure the best performance, keep the underside of the lawn mower housing clean. Be especially careful to keep the kickers free of debris (Figure 32). Installing the Blade 1.
Scraping Method If washing does not remove all debris from under the lawn mower, scrape it clean. 1. Disconnect the wire from the spark plug (Figure 12). 2. Drain the fuel from the fuel tank. Refer to Emptying the Fuel Tank and Cleaning the Fuel Filter. Grass clippings and other objects can be thrown from an open discharge tunnel and cause serious injury or kill the operator or bystanders.
Storage 2. Clean any dirt and chaff from the cylinder, cylinder head fins, and blower housing. To prepare the lawn mower for off-season storage, perform the recommended maintenance procedures. Refer to Maintenance. 3. Remove grass clippings, dirt, and grime from the external parts of the engine, the shrouding, and the top of the lawn mower housing. Store the lawn mower in a cool, clean, dry place. Cover the lawn mower to keep it clean and protected. 4. Check the condition of the blade.
Troubleshooting Problem Engine does not start Engine starts hard or loses power Possible Cause 1. The fuel tank is empty or the fuel system contains stale fuel. 1. Drain and/or fill the fuel tank with fresh gasoline. If the problem persists, contact an Authorized Service Dealer. 2. The engine has not been primed. 3. The wire is not connected to the spark plug. 4. The spark plug is pitted, fouled, or the gap is incorrect. 2. Prime the engine. 3. Connect the wire to the spark plug. 1.
Problem Lawn mower does not self-propel Possible Cause Corrective Action 1. The self-propel drive cable is out of adjustment or is damaged. 1. Adjust the self-propel drive cable. Replace the cable if necessary. 2. There is debris under the belt cover. 2. Clean the debris from under the belt cover.
