Safety • Never mow while people (especially children) or pets are nearby. Stop the lawn mower if anyone enters the area. • Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the lawn mower and the mowing activity. Never assume that children will remain where you last saw them. • Keep children out of the mowing area and under the watchful care of a responsible adult. • Be alert and turn the lawn mower off if children enter the area.
any source of ignition until the gasoline vapors have dissipated. – Replace all fuel tank and container caps securely. – If you must drain the fuel from the fuel tank, do it outdoors. • Replace faulty mufflers. • Before using, always visually inspect the blades, blade bolts, and cutter assembly for wear or damage. Replace worn or damaged blades and bolts in sets to preserve balance. • On multibladed lawn mowers, use care as rotating one blade can cause the other blades to rotate.
• Watch for holes, ruts, or bumps. Tall grass can hide obstacles. • Do not change the speed settings on the engine. • Do not mow near drop-offs, ditches, or embankments. You could lose your footing or balance. • If you must drain the fuel from the fuel tank, do it outdoors. • Do not mow on wet grass. Reduced footing could cause slipping. • To ensure the best performance and safety, purchase only genuine Toro replacement parts and accessories.

Operation Filling the Fuel Tank with Gasoline Note: Determine the left and right sides of the machine from the normal operating position. 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.
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. Figure 10 1. 2. 3.

Checking the Blade Brake Clutch Check the blade control bar before each use to ensure that the blade brake clutch system is operating properly. Normal Test Figure 15 1. Stop the engine and wait for all moving parts to stop. 9. Lift the blade control bar up to about one inch (2.5 cm) below the handle; refer to position A in Figure 16. 2. Move the mower onto a paved surface in a non-windy area. 3. Set all 4 wheels in to the 2-1/2 inch (64 mm) cutting height setting.
13. Walk around the mower to check for the newspaper ball. If the ball did not go under the housing, repeat steps 6 through 12. 14. Pull the mower away from the newspaper. If the newspaper ball unravels or is shredded, the blade has not properly stopped, resulting in an unsafe operating condition. Contact an Authorized Service Dealer. A. Place the ball of newspaper 5 inches (12.7 cm) in front of the mower (Figure 14). B. Start the engine. C. Follow steps 2 through 6 above. 8.
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 20 1. Adjusting the cutting height levers could bring your hands into contact with a moving blade and result in serious injury. 2. Bag frame on retaining post Pin engaged in catch 3.
Operating Tips Mowing with the Grass Bag General Tips 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. • Review the safety instructions and read this manual carefully before operating the mower. • Clear the area of sticks, stones, wire, branches, and other debris that the blade could hit and throw. Check the grass bag frequently.
set the front wheels at 2-1/4 inches (57 mm) and the rear wheels at 2-3/4 inches (70 mm). 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. 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.

Lubrication Engine Maintenance Lubricating the Pivot Arms Servicing the Air Cleaner Important: Do not operate the engine without the air filter assembly; extreme engine damage will occur. 1. Stop the engine and wait for all moving parts to stop. 2. Disconnect the wire from the spark plug. 3. Remove the 2 wing bolts that secure the cover (Figure 24). 1. Move the rear wheel cutting height levers to the center setting. 2. Wipe the grease fittings with a clean rag (Figure 22). Figure 22 1. Grease tting 3.
10. Dip the foam element in clean engine oil, then squeeze out the excess oil. 9. Insert the dipstick into the filler neck and rotate the cap clockwise until it is tight. Note: Excess oil in the foam element restricts the air flow through the element and may reach the paper filter and clog it. 11. Wipe dirt from the base and the cover with a moist rag. 10. Wipe up any spilled oil. 11. Connect the wire to the spark plug. 12. Recycle the used oil according to local codes.
Drive System Maintenance Servicing the Wheels Removing the Wheels 1. Stop the engine and wait for all moving parts to stop. 2. Disconnect the wire from the spark plug. 3. Remove the bolt, the wheel spacer, and the locknut mounting the wheel to the pivot arm (Figure 28). Adjusting the Self-propel Drive If the mower does not self-propel or has a tendency to creep forward when the blade control bar is more than 1-1/2 inches (3.
uniform fit, until the wheel halves are drawn together (Figure 28). Do not overtighten the blade brake cable. Overtightening the blade brake cable could cause the blade brake to come off of the brake drum. If the brake does not contact the drum, the blade will not stop rotating when you release the control bar. A rotating blade could cause serious personal injury. 6. Install the 2 bolts and 2 locknuts previously removed in the remaining holes in the wheel halves and tighten.
Inspecting the Blade remain balanced if you remove the same amount of material from both cutting edges. Carefully examine the blade for sharpness and wear, especially where the flat and the curved parts meet (A). Because sand and abrasive material can wear away the metal that connects the flat and curved parts of the blade, check the blade before using the mower. If you notice a slot or wear (Figure 31B and C), replace the blade; refer to Removing the Blade. Figure 32 1. Sharpen at this angle only. 2.
2. Return the mower to its operating position. 4. Stop the engine and wait for all moving parts to stop. 3. Connect the wire to the spark plug. 5. Turn off the water. Cleaning 6. Start the mower and let it run for a few minutes to dry out the mower and its components. Cleaning under the Mower Housing Scraping Method To ensure the best performance, keep the underside of the mower housing clean. Be especially careful to keep the kickers free of debris (Figure 34). 1.
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 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. Never start or operate the mower unless one of the following is true: Tipping the mower may cause the fuel to leak from the carburetor or the fuel tank.
Storage General Information 1. Clean the mower housing. Refer to Cleaning under the Mower Housing. To prepare the mower for off-season storage, perform the recommended maintenance procedures. Refer to Maintenance on page 7. 2. Clean any dirt and chaff from the cylinder, cylinder head fins, and blower housing. Store the mower in a cool, clean, dry place.
