2.Tip mower so that it rests on the housing. Keep the side with the air cleaner facing up. Hold mower firmly.

WARNING: Never tip the mower more than 90º in any direction and do not leave the mower tipped for any length of

time. Oil can drain into the upper part of the engine causing a starting problem.

3.Scrape and clean the underside of the deck with a suitable tool. Do not spray with water.

4.Put the mower back on its wheels on the ground. If you had put plastic under the gas cap earlier, make sure to remove it now.
