WARNING: Always stop engine, disconnect spark
plug, and ground against engine before performing
any type of maintenance on your machine.

any direction and do not leave the mower tipped for
any length of time. Oil can drain into the upper part

Scrape and clean the underside of the deck with a suitable
tool. Do not spray with water.
IMPORTANT: Do not use a pressure washer or garden hose
to clean your unit. These may cause damage to bearings,

and reduce serviceability.
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.
