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 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.

Note: To disengage the traction drive but keep the blade engaged, gradually release the blade control bar to the B position. To self-propel with the blade disengaged, squeeze the blade control bar against handle to the C position without sliding the blade control bar to the right. The lawn mower has 3 ground speeds. 1 is slow, 2 is medium, and 3 is fast. The ground speed control is located at the rear of the belt cover (Figure 13). Normal Test 1. Stop the engine and wait for all moving parts to stop. 2.
Note: The fan-like noise indicates that the lawn mower blade is turning. 3. Bring the blade control bar up into the middle position about 5 inches (12.7 cm) below the handle cross bar (Position C in Figure 19). Figure 19 Figure 17 1. 1 inch (2.5 cm) Note: This intermediate position (C) is not the normal operating position of the blade control bar. However, it helps to detect a sticking blade brake clutch system early enough to prevent an unsafe condition later. 10.
If the blade brake clutch system is inoperative, the blade will continue to rotate when you release the blade control bar. Contact with blade could occur, causing serious injury. 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. • Check the blade brake clutch system operation before each use.
Mowing with the Grass Bag 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. Check the grass bag frequently. If it is damaged, install a new Toro replacement bag. Figure 21 1. Bag frame on retaining post 2. Pin engaged in catch 3.

Operating Tips General Tips 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. • Review the safety instructions and read this manual carefully before operating the lawn mower. • Clear the area of sticks, stones, wire, branches, and other debris that the blade could hit and throw.
set the front wheels at 2 inches (51 mm) and the rear wheels at 2-1/2 inches (64 mm). 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. • 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.
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 rst 8 operating hours • Change the engine oil without the oil lter. Before each use or daily • • • • • Check the engine oil level. Check the operation of the blade brake clutch. Inspect the mower blades for wear or damage. Clean under the lawn mower housing.
