Maintenance
General Recommendations
Always observe safety rules when performing any 
maintenance.
The warranty on this lawn mower does not cover items that 
have been subjected to operator abuse or negligence. To 
receive full value from warranty, operator must maintain 
the lawn mower as instructed here.
Changing of engine-governed speed will void engine 
warranty.
All adjustments should be checked at least once each 
season.
Periodically check all fasteners and make sure these are 
tight.
WARNING: 
Always stop engine, disconnect spark 
plug, and ground against engine before performing 
any type of maintenance on your machine.
Lubrication
Lubricate pivot points on the blade control at least once 
a season with light oil. This control must operate freely in 
both directions. See Fig. 6-1.
Lubricate the wheels at least once a season with light oil (or 
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.
Lubricate the torsion springs and pivot points on the rear 
discharge door periodically with light oil to prevent rust. 
See Fig. 6-1.

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 
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 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.
Engine Care
NOTE: Refer to the Engine Operation and Maintenance sections 
in this manual for detailed instructions.
Maintain oil level.
Service air cleaner every 25 hours under normal conditions. 
Clean every few hours under extremely dusty conditions.
Clean spark plug and reset the gap once a season.
Clean engine regularly with a cloth or brush. Keep the area 
around the top of the engine clean to permit proper air 
circulation. Remove all grass, dirt, and combustible debris 
from muffler area.
