motor oil). If wheels are removed for any reason, lubricate
surface of the pivot arm and inner surface of the wheel
with light oil. See Fig. 6-1.
3. Lubricate the torsion spring and pivot points on the rear
discharge door and side mulch plug periodically with light
oil to prevent rust. See Fig. 6-1.
4. The transmission is pre-lubricated and sealed at the factory
and does not require lubrication.

schedule and instruction for engine lubrication.
DeckCare
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.
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. Keep the side
with the air cleaner facing up. Hold mower firmly.
WARNING:
Never tip the mower more than 90 ° 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. Ifyou had
put plastic under the gas cap earlier, make sure to remove it
now.
