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.

Using the Self-propel Drive Note: You can vary the ground speed by increasing or decreasing the distance between the control bar and the handle. Lower the control bar to slow the lawn mower when making a turn or if the lawn mower is moving too fast for you. If you lower the control bar too far, the lawn mower stops self-propelling. Squeeze the control bar closer to the handle to increase the ground speed.
Adjusting the Cutting Height 2. Ensure that the discharge door handle is fully forward and that the pin is engaged in the catch (Figure 18). Each wheel is adjusted individually with a wheel height adjustment lever. Cutting heights are 1 inch (25 mm), 1-1/2 inches (38 mm), 2 inches (51 mm), 2-1/2 inches (64 mm), 3 inches (76 mm), and 3-1/2 inches (89 mm). Adjusting the cutting height levers could bring your hands into contact with a moving blade and result in serious injury.
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 lawn mower. • Clear the area of sticks, stones, wire, branches, and other debris that the blade could hit and throw.
