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 should stop. If it does 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 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.
Operating the Blade Engaging the Blade When you start your engine, the blade does not turn. You must engage the blade to mow. 1. Push the control bar lock forward (Figure 12). Figure 11 1. Fuel tank cap 2. Oil fill/dipstick 3. Air cleaner 2. Remove the cap from the tank. 3. Fill the fuel tank with unleaded gasoline to within 1/4 to 1/2 inch (6 to 13 mm) from the top of the tank. Do not fill into the filler neck. Figure 12 2. Pull the blade control bar to the handle and hold it (Figure 13).
Disengaging the Blade Disengaging the Traction Drive Release the blade control bar. Release the traction control bar. Important: When you release the blade control bar, the blade should stop within 3 seconds. If it does not stop properly, stop using your mower immediately and contact an Authorized Service Dealer. Checking the Blade Brake Clutch Check the blade control bar before each use to ensure that the blade brake clutch system is operating properly. Operating the Traction Drive 1.
Adjusting the Cutting Height Using the Grass Bag Each wheel is adjusted individually with a wheel height adjustment lever. Cutting heights are 1-1/4 inches (32 mm), 1-3/4 inches (44 mm), 2-1/4 inches (57 mm), 2-3/4 inches (70 mm), 3-1/4 inches (83 mm), and 3-3/4 inches (95 mm). Installing the Grass Bag 1. Wait for all moving parts to stop. 2. Raise and hold up the rear door (Figure 17).
The mower can throw grass clippings and other objects through an open discharge tunnel. Objects thrown with enough force could cause serious personal injury or death to the operator or bystander. Operating a mower with its engine running at a speed greater than the factory setting can cause the 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. Do not operate the mower without a grass bag installed.
• For light leaf coverage, set all the wheels at the same cutting height setting. • If there are more than 5 inches (12.7 cm) of leaves on the lawn, set the front cutting height 1 or 2 notches higher than the rear cutting height. This makes it easier to feed the leaves under the mower housing. • Slow down your mowing speed if the mower does not cut the leaves finely enough. • If you mow over oak leaves, you can add lime to the grass in the spring to reduce the acidity of the oak 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 first 8 hours • Change the engine oil. Before each use or daily • Check the engine oil level. • Inspect the mower blades for wear or damage. • Clean under the mower housing. Every 25 hours • Clean the foam pre-cleaner (more frequently in dusty conditions).
Lubrication Engine Maintenance Lubricating the Pivot Arms Servicing the Air Filter Service Interval: Every 50 hours 1. Move the rear wheel cutting height levers to the center setting. 2. Wipe the grease fittings with a clean rag (Figure 19). 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). Clean the foam pre-cleaner every 25 operating hours.
Changing the Engine Oil Service Interval: After the first 8 hours Every 50 hours Oil Capacity With oil filter 29 ounces (0.85 liters) Without oil filter 22 ounces (0.65 liters) Note: The oil capacities in the table above account for the empty crankcase to contain a small amount of residual oil. 1. Run the engine to warm the engine oil. Figure 21 1. Cover 2. Paper air filter Note: Warm oil flows better and carries more contaminants. 3. Air filter base 4.
Changing the Oil Filter 9. Fill the crankcase to the Full line on the dipstick with fresh oil. Refer to Filling the Crankcase with Oil. Service Interval: Every 100 hours 1. Run the engine to warm the 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. Oil may be hot after the engine has been run, and contact with hot oil can cause severe personal injury. 13.
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 11). 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 Adjusting the Self-propel Drive If the 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 self-propel drive. 1. Loosen the nut that secures the adjuster (Figure 25). Figure 26 1. Upper belt cover 2. Lower belt cover 7. Remove the screws from the lower anchor bracket (Figure 27). Figure 25 1. Adjuster 2. Nut 3. Cable 4. 1-1/2 inches (3.8 cm) 2.
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 11). 3. Remove the fuel tank from the tank bracket. Note: You do not need to disconnect the fuel line from the fuel tank. Figure 29 4.
Blade Maintenance Do not overtighten the blade brake cable. Overtightening the blade brake cable could prevent the blade brake from contacting the brake drum when you release the control bar. If the blade brake does not contact the brake drum, the blade will not stop rotating, which could cause serious personal injury. Maintaining the Cutting Blade Always mow with a sharp blade. A sharp blade cuts cleanly and without tearing or shredding the grass blades. 1.
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 34). Figure 32 Figure 34 3. Wear 4. Slot formed 1. Sail 2. Flat part of the blade Note: You can also check the balance using a commercially manufactured blade balancer. 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. 2.
Cleaning Tipping the 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. Cleaning under the Mower Housing To ensure the best performance, keep the underside of the mower housing clean. Avoid fuel spills by running the engine dry or by removing the gasoline with a hand pump; never siphon. Washing Method Service Interval: Before each use or daily 3.
Storage To prepare the mower for off-season storage, perform the recommended maintenance procedures. Refer to Maintenance. Store the mower in a cool, clean, dry place. Cover the mower to keep it clean and protected. Preparing the Fuel System Gasoline can vaporize if you store it over long periods of time and explode if it comes into contact with an open flame.
