Deck Care
Clean underside of the mower deck after each use to prevent
build-up of grass clippings or other debris. Follow steps below
for this job.

Disconnect spark plug wire. Drain gasoline from lawn
mower or place a piece of plastic under the gas cap.

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

of the engine causing a starting problem.

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.
