Training Safety • Read the Operator’s Manual and other training material. This lawn mower meets or exceeds the CPSC blade safety requirements for walk-behind rotary lawn mowers and the B71.4 specifications of the American National Standards Institute in effect at the time of production. • If the operator(s) or mechanic(s) cannot read English it is the owner’s responsibility to explain this material to them. • Become familiar with the safe operation of the equipment, operator controls, and safety signs.
Operation Maintenance and Storage • Never run an engine in an enclosed area. • Wait for all movement to stop before adjusting, cleaning or repairing. • Only operate in good light, keeping away from holes and hidden hazards. • Clean grass and debris from cutting unit, muffler, and engine to help prevent fires. • Be sure all drives are in neutral and parking brake is engaged before starting engine. • Clean up oil or fuel spillage. • Only start engine from the operator’s position.
Safety and Instructional Decals Safety decals and instructions are easily visible to the operator and are located near any area of potential danger. Replace any decal that is damaged or lost.

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 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. This machine produces sound levels in excess of 85dBA at the operator’s ear and can cause hearing loss through extended periods of exposure.
Filling the Fuel Tank with Gasoline 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. You may use leaded gasoline if unleaded gasoline is not available. Important: Do not add oil to the 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. • 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.
5. Pull the starter handle lightly until you feel resistance, then pull it sharply. 6. Regulate the throttle and the ground speed control as desired when the engine starts. the Run/Drive position; this can damage the transmission. Move the blade control bar to the Run/Shift position (Figure 16) when you change the ground speed. Note: You can vary the ground speed by increasing or decreasing the distance between the control bar and the handle.
Adjusting the Cutting Height 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. Figure 18 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 blade 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). 1. Move the rear wheel cutting height levers to the center setting. Every 300 hours—Replace the paper air filter (more frequently in dusty conditions). 2. Wipe the grease fittings with a clean rag (Figure 20).
Changing the Engine Oil Changing the Oil Filter Service Interval: After the first 8 hours Service Interval: Every 100 hours 1. Run the engine to warm the oil. Every 50 hours 1. Run the engine to warm the engine oil. Note: Warm oil flows better and carries more contaminants. Oil may be hot after the engine has been run, and contact with hot oil can cause severe personal injury. Avoid contacting the hot engine oil when you drain it.
Fuel System Maintenance 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. 11. Run the engine for about 3 minutes. Emptying the Fuel Tank and Cleaning the Fuel Filter 12. Stop the engine, wait for all moving parts to stop, and check for oil leakage around the filter. Service Interval: Every 50 hours—Check the fuel hose and replace it if necessary. 10.
Drive System Maintenance Controls System Maintenance Adjusting the Self-propel Drive Adjusting the Blade Brake Cable Service Interval: Every 100 hours Service Interval: Before each use or daily—Ensure that the engine stops within 3 seconds after releasing the blade control bar. 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.
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. A worn or damaged blade can break, and a piece of the blade could be thrown into the operator’s or bystander’s area, resulting in serious personal injury or death. 1.
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 Installing the Blade 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 33).
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 13). 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.
General Information Storage 1. Clean the lawn mower housing. Refer to Clean under the Lawn Mower Housing. To prepare the lawn mower for off-season storage, perform the recommended maintenance procedures. Refer to Maintenance. 2. Clean any dirt and chaff from the cylinder, cylinder head fins, and blower housing. Store the lawn mower in a cool, clean, dry place. Cover the lawn mower to keep it clean and protected. 3.
