Product Overview Operation Note: Determine the left and right sides of the machine from the normal operating position. Each time before you mow, ensure that the self-propel drive and the blade-control bar operate properly. When you release the blade-control bar, the blade and the self-propel drive should stop. If they do not, contact an Authorized Service Dealer.
Checking the Engine-oil Level • Ethanol: Gasoline with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use. Never use gasoline that contains more than 10% ethanol by volume, such as E15 (contains 15% ethanol), E20 (contains 20% ethanol), or E85 (contains up to 85% ethanol).

Operating the Self-Propel Drive the Run/Shift position (Figure 17) whenever you change the ground speed. Note: You can vary the ground speed by increasing or decreasing the distance between the blade-control bar and the handle. Lower the bar to decrease the ground speed when you are making a turn or if the machine is moving too fast for you. If you lower the bar too far, the machine stops self-propelling. Squeeze the bar closer to the handle to increase the ground speed.
Removing the Grass Bag Bagging the Clippings Use the grass bag when you want to collect grass and leaf clippings from the lawn. DANGER The machine can throw grass clippings and other objects through an opening in the mower housing.
