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.
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 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.
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.
Engine Care
A list of key engine maintenance jobs required for good
performance by the mower is given below. Follow the
accompanying engine manual for a detailed list and instructions.
•
Maintain oil level as instructed in engine manual.
•
Service air cleaner every 25 hours under normal conditions.
Clean every few hours under extremely dusty conditions.
Poor engine performance and flooding usually indicates
that the air cleaner should be serviced. To service the air
cleaner, refer to the engine manual.
•
Clean spark plug and reset the gap once a season. Spark
plug replacement is recommended at the start of each
mowing season. Check engine manual for correct plug
type and gap specifications.
•
Clean engine regularly with a cloth or brush. Keep the
top of the engine clean to permit proper air circulation.
Remove all grass, dirt, and combustible debris from muffler
area.
•
Engines stored between 30 and 90 days need to be treated
with a gasoline stabilizer such as STA-BIL® to prevent
deterioration and gum from forming in fuel system or on
essential carburetor parts.
