Note: Use a flat-head screw driver to unclip the battery cover (Fig. 8). Unclip both ends of the battery cover before removing it to prevent damaging it. Before Starting Filling the Crankcase with Oil The crankcase can hold 22 ounces (0.65 liters) of oil. Use only high-quality, SAE 30 or SAE 10W30 weight detergent oil that has the American Petroleum Institute (API) service classification SF, SG, SH, or SJ.
Filling the Fuel Tank with Gasoline Danger 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. Unleaded gasoline burns cleaner, extends engine life, and promotes good starting.
Reviewing the Maintenance Schedule Note: Do not use the primer to start a warm engine after a brief shutdown. However, cool weather may require you to prime the engine again. Review the Recommended Maintenance Schedule on page 14. You may need to perform one or more additional procedures before or soon after you begin operating the lawn mower. 3. Hold the blade control bail against the upper handle (Fig. 14).
• Do not cut below the D setting unless the grass is sparse or it is late fall when grass growth begins to slow down. When you cut long grass, use a higher cutting height setting and walk slower; then cut the grass again at a normal setting. Mowing the grass when it is too long can plug the lawn mower and cause the engine to stall.
5. Pull the discharge door handle forward and then move it rearward until the pin locks in the bag notch (Fig. 20). 6. Adjust all the wheels to the same letter setting.

Danger Warning If the discharge door does not close completely, the lawn mower could throw objects, causing serious personal injury or death. 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.
• If there are more than 5 inches (12.7 cm) of leaves on the lawn, set the front cutting height one or 2 notches higher than the rear cutting height. This makes it easier to feed the leaves under the lawn mower deck. • If you mow over oak leaves, you can add lime to the grass in the spring to reduce the acidity of the oak leaves. • Slow down your mowing speed if the lawn mower does not cut the leaves finely enough.
