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.
If the oil level is below the lower limit mark, add oil. Refer to Filling the Crankcase with Oil. 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. Filling the Fuel Tank with Gasoline • Always place gasoline containers on the ground and away from your vehicle before filling. For best results, use clean, fresh, lead-free gasoline with an octane rating of 87 or higher.
4. Pull the starter handle lightly until you feel resistance, then pull it sharply. Allow the rope to return to the handle slowly. 5.

point where it could result in an unsafe operating condition. Contact an Authorized Service Dealer for an inspection and repair of your mower. Adjusting the cutting height levers could bring your hands into contact with a moving blade and result in serious injury. • Stop the engine and wait for all movement to stop before adjusting the cutting height. If the blade brake clutch system is inoperative, the blade will continue to rotate when you release the blade control bar.
Removing the Grass Bag 1. Stop the engine and wait for all moving parts to stop. 2. Raise the discharge door handle and move it forward to engage the pin with the catch (Figure 22). 3. Grasp the handles at the front and the rear of the bag and lift the bag off the mower. 4. Gradually tip the bag forward to empty the clippings. 5. To install the bag, refer to Installing the Grass Bag. Figure 22 1. Bag frame on retaining post 2. Pin engaged in catch 3.
• Maintain a sharp blade throughout the cutting season. Periodically file down nicks on the blade. the leaves clump on top of the lawn, the mower may plug and cause the engine to stall. • Replace the blade when necessary with an original Toro replacement blade. • Alternate the mowing direction. This helps disperse the clippings over the lawn for even fertilization. • Mow only dry grass or leaves. Wet grass and leaves tend to clump on the yard and can cause the mower to plug or the engine to stall.
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 5 hours • Change the engine oil. Before each use or daily • • • • • • • Check the engine oil level. Check the blade brake clutch operation. Inspect the air cleaner elements. Inspect the mower blades for wear or damage. Clean under the mower housing.
Lubrication Engine Maintenance Lubricating the Pivot Arms Servicing the Air Cleaner Service Interval: Every 50 hours Service Interval: Before each use or daily—Inspect the air cleaner elements. Every 25 hours—Clean the air filter elements. Clean them more frequently in dusty operating conditions. Every 250 hours—Replace the air cleaner elements. Replace them more frequently in dusty operating conditions. 1. Move the rear wheel cutting height levers to the center setting. 2.
8. After draining the oil, return the mower to its operating position. 9. Fill the crankcase to the upper limit mark on the dipstick with fresh oil. Refer to the Filling the Crankcase with Oil. 10. Insert the dipstick into the filler neck and rotate the cap clockwise until it is tight. 11. Wipe up any spilled oil. 12. Recycle the used oil according to local codes. 8. If the paper element is excessively dirty, replace it.
Drive System Maintenance Important: A loose spark plug can become very hot and can damage the engine; overtightening a spark plug may damage the threads in the cylinder head. 8. Connect the wire to the spark plug. Adjusting the Self-propel Drive 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. 1.
Servicing the Wheels tighten. Remove the 2 long screws or bolts and replace them with 2 bolts and 2 locknuts (Figure 30). Removing the Wheels 7. Install the wheel to the pivot arm with the bolts, a spacer, and a locknut. Ensure that the spacer is positioned between the wheel hub and the pivot arm (Figure 30). Service Interval: Every 100 hours 1. Stop the engine and wait for all moving parts to stop. 2. Disconnect the wire from the spark plug. 3.
Controls System Maintenance Blade Maintenance Adjusting the Blade Brake Cable 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. 3. Drain the gasoline from the fuel tank. 4. Tip the mower onto its left side (air cleaner up)(Figure 32).
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. 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.
Scraping Method Cleaning If washing does not remove all debris from under the mower, scrape it clean. Cleaning under the Mower Housing 1. Disconnect the wire from the spark plug. 2. Drain the fuel from the fuel tank. To ensure the best performance, keep the underside of the mower housing clean. Be especially careful to keep the kickers free of debris (Figure 36). Tipping the mower may cause the fuel to leak from the carburetor or the fuel tank.
3. Drain the gasoline from the fuel tank. 4. Tip the mower on its left side. Grass clippings and other objects can be thrown from an open discharge tunnel and cause serious injury or kill the operator or bystanders. 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.
Storage 2. Clean any dirt and chaff from the cylinder, cylinder head fins, and blower housing. To prepare the 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 mower housing. Store the mower in a cool, clean, dry place. Cover the mower to keep it clean and protected. 4. Check the condition of the blade. Refer to Maintaining 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 throttle lever is not in the Choke position. 3. The wire is not connected to the spark plug. 4. The spark plug is pitted, fouled, or the gap is incorrect. 2. Move the throttle lever to the Choke position. 3.
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.
