CleaninG deCk
Clean underside of the mower deck once a season to prevent build-up
of grass clippings or other debris. Follow steps below for this job.
1. Disconnect spark plug wire. Drain gasoline from lawn mower or place a
piece of plastic under the gas cap.
2. Tip mower so that it rests on the housing,
down. 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.
IMPORTANT: Do not use a pressure washer or garden hose to clean
your unit. These may cause damage to bearings, or the engine. The
use of water will result in shortened life and reduce serviceability.
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.
