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 control bar operate properly. When you release the control bar, the blade and self-propel drive should stop. If they do not, contact an Authorized Service Dealer. CAUTION 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 DANGER Gasoline is extremely flammable and explosive. A fire or explosion from gasoline can burn you and others. • To prevent a static charge from igniting the gasoline, place the container and/or machine directly on the ground before filling, not in a vehicle or on an object. • Fill the tank outdoors when the engine is cold. Wipe up spills. • Do not handle gasoline when smoking or around an open flame or sparks.
Stopping the Engine 1. Release the control bar and move the throttle control to the Off position. 2. Disconnect the wire from the spark plug if you do not plan to use the machine or if you leave it unattended. 1 Operating the Self-propel Drive and Engaging the Cutting Blade 2 G019672 Figure 15 1. Slide the control bar to the right. This machine is equipped with a blade brake clutch.
2. Move the machine onto a paved surface in a non-windy area. 3. Set all 4 wheels to the 2-3/4 inches (70 mm) cutting height setting; refer to Adjusting the Cutting Height (page 15). 4. Set the ground speed selector to the Neutral (N) position. 5. Take a half sheet of newspaper and crumple it into a ball small enough to go under the deck (about 3 inches or 76 mm in diameter) as shown in Figure 16. Figure 18 1. 1 inch (2.5 cm) 11. Release the control bar; refer to position B in Figure 19.

Release the control bar. If the bag does not immediately deflate, it indicates that the blade is still rotating.
Installing the Grass Bag Mowing with the Grass Bag 1. Stop the engine and wait for all moving parts to stop. WARNING 2. Ensure that the discharge door handle is fully forward and that the pin is engaged in the catch (Figure 22). A worn grass bag could allow small stones and other similar debris to be thrown in the operator's or bystanders’ direction and result in serious personal injury or death to the operator or bystanders. Check the grass bag frequently.
