Operation Recommended Gasoline Note: Determine the left and right sides of the machine from the normal operating position. Use UNLEADED Regular Gasoline suitable for automotive use (87 pump octane minimum). Leaded regular gasoline may be used if unleaded regular is not available. Think Safety First Important: Never use methanol, gasoline containing methanol, or gasohol containing more than 10% ethanol because the fuel system could be damaged. Do not mix oil with gasoline.
• Cleans the engine while it runs • Eliminates gum-like varnish buildup in the fuel system, which causes hard starting In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. Important: Do not use fuel additives containing methanol or ethanol. Add the correct amount of gas stabilizer/conditioner to the gas.

does not operate as described below, have an Authorized Service Dealer repair the safety system immediately. 1. While sitting on the seat, with the control levers in park position, and move the blade control switch to On. Try starting the engine; the engine should not crank. 2. While sitting on the seat, move the blade control switch to Off. Move either motion control lever to the center, unlocked position. Try starting the engine; the engine should not crank. Repeat with the other motion control lever.
Forward Stopping the Machine 1. Move the levers to the center, unlocked position. To stop the machine, move the motion control levers to neutral and outward to the park position, disengage the blade control switch, ensure the throttle is in the fast position, and turn the ignition key to off. Remember to remove the key from the ignition switch. 2. To go forward, slowly push the motion control levers forward (Figure 11).
Positioning the Seat The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable. 1. Raise the seat and loosen the adjustment knobs enough to move the seat (Figure 13). Important: Make sure that the spacers stay in place when loosening the knobs to move the seat. Loss of the spacers can result in damage to the seat. 2. Move the seat to the desired position and tighten the knobs. Figure 14 1. Control lever 2. Bolt 3.
Side Discharge The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. Without the grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris will cause injury or death. Figure 15 1. Bypass levers 3. 2.
Cut 1/3 of the Grass Blade inside the mower, cutting quality will eventually become unsatisfactory. It is best to cut only about 1/3 of the grass blade. Cutting more than that is not recommended unless grass is sparse, or it is late fall when grass grows more slowly. Blade Maintenance Maintain a sharp blade throughout the cutting season because a sharp blade cuts cleanly without tearing or shredding the grass blades.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval After the rst 10 operating hours Before each use or daily Maintenance Procedure • Change the engine oil. • • • • • Check the safety interlock system. Check the air lter. Check the engine oil level. Check the cutting blades. Clean the mower housing. Every 25 hours • Grease all lubrication points. • Check tire pressure.
Premaintenance Procedures 1. Park the machine on a level surface and disengage the blade control switch. 2. Move the motion control levers outward to the park position, stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. Removing and Installing the Engine Hood 3. Clean the grease fittings (Figure 19 and Figure 20) with a rag. Make sure to scrape any paint off of the front of the fitting(s). 1.
Note: Service the air filter more frequently if used in dusty areas. Cleaning the Foam Element 1. Wash the foam element in warm, soapy water or nonflammable solvent. Squeeze the element, but do not twist, and allow it to dry thoroughly (Figure 22). Do not use gasoline as a cleaning solvent. Removing the Foam and Paper Elements 1. Park the machine on a level surface and disengage the blade control switch. 2.
Crankcase Capacity: • 0.95 qt (0.9 l) when the filter is not changed; • 1.11 qt (1.05 l) when the filter is changed Viscosity: 10W-30 is recommended for general use. Other viscosities shown in the chart below may be used when the average temperature in you area is within the indicated range. Figure 24 1. Paper element 2. Compressed air at 30 psi or lower. Important: Never try to brush dirt from the paper filter; brushing will force dirt into the fibers.
Note: Dispose of the used oil at a recycling center. 4. Insert oil dipstick fully onto the fill hole, but do not screw it in. 5. Pull the dipstick out, and look at the end. If the oil level is near or below the lower limit mark, slowly pour only enough oil into the fill hole to raise the level to the upper limit mark on the dipstick. Do not overfill. (Figure 26). 9. Change the oil filter, if necessary (Figure 28). 10. Clean around the oil dipstick and unscrew the cap (Figure 26). 11.
Checking the Spark Plug 5. Add the specified amount of the recommended oil; refer to Changing and Draining the Oil in Engine Maintenance, page 22. 6. Start the engine and check the filter for leaks. 7. Stop the engine and check the oil level; refer to Checking the Oil Level in Engine Maintenance, page 22. Add oil if necessary. 1. Look at the center of the spark plug (Figure 30). If you see light brown or gray on the insulator, the engine is operating properly.
Fuel System Maintenance Draining the Fuel Tank In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property. • Drain gasoline from the fuel tank when the engine is cold. Do this outdoors in an open area. Wipe up any gasoline that spills. Figure 32 1. 2. • Never smoke when draining gasoline, and stay away from an open flame or where a spark may ignite the gasoline fumes.
Electrical System Maintenance Incorrect battery cable routing could damage the machine and cables causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury. Servicing the Battery Check the electrolyte level in the battery every 25 hours. Always keep the battery clean and fully charged. Use a paper towel to clean the battery case. If the battery terminals are corroded, clean them with a solution of four parts water and one part baking soda.
Checking the Battery Electrolyte Level 4. Slowly pour distilled water into each battery cell until the electrolyte level is up to the Upper line (Figure 34) on the battery case. Important: Do not overfill the battery because electrolyte (sulfuric acid) can cause severe corrosion and damage to the chassis. Battery electrolyte contains sulfuric acid which is a deadly poison and causes severe burns. • Do not drink electrolyte and avoid contact with skin, eyes or clothing.

sharpen the blades; refer to Sharpening the Blades. 2. Inspect the blades, especially the curved area (Figure 38). If you notice any damage, wear, or a slot forming in this area (item 3 in Figure 38), immediately install a new blade. Figure 37 1. Valve stem Mower Maintenance Figure 38 Servicing the Cutting Blades 1. 2. Maintain sharp blades throughout the cutting season because sharp blades cut cleanly without tearing or shredding the grass blades.
A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders. Figure 41 1. Sharpen at original angle • Always replace bent or damaged blade with a new blade. • Never file or create sharp notches in the edges or surfaces of blade. 2. Check the balance of the blade by putting it on a blade balancer (Figure 42). If the blade stays in a horizontal position, the blade is balanced and can be used.
Adjusting the Front-to-Rear Blade Slope 3. Check the air pressure of all four tires. If needed, adjust to the recommended inflation; refer to Checking the Tire Pressure in Drive System Maintenance, page 30. 4. Set the height-of-cut lever to position D [3 inch (76 mm)]. 5. Carefully rotate the blade(s) side to side (Figure 43). Measure between the outside cutting edges and the flat surface (Figure 43).
9. Set the height-of-cut at position D [3 inch (76 mm)] and carefully rotate the blades so they are facing front to rear (Figure 46). 10. Measure from the tip of the front blade to the flat surface and the tip of the rear blade to the flat surface (Figure 46). If the front blade tip is not 1/16-5/16 inch (1.6-7.9 mm) lower than the rear blade tip, adjust the front locknuts. Figure 47 1. Locknut and adjusting nut 2. Front tire 3. 4. Adjustment nut Lock nut 14.
Check the belts for cracks, frayed edges, burn marks, or any other damage. Replace damaged belts. Replacing the Mower Belt Squealing when the belt is rotating, blades slipping when cutting grass, frayed belt edges, burn marks, and cracks are signs of a worn mower belt. Replace the mower belt if any of these conditions are evident. 1. Park the machine on a level surface and disengage the blade control switch. Figure 48 1. Hairpin cotter and clevis pin 2. Support rod 2.
Replacing the Grass Deector The spring is under tension when installed and can cause personal injury. Be careful when removing the spring. An uncovered discharge opening could allow the lawn mower to throw objects in the operator’s or bystander’s direction and result in serious injury. Also, contact with the blade could occur. 6. Route the new belt around the engine pulley and mower pulleys (Figure 50). 7.
