SECTION 7:  MAINTAINING YOUR LAWN MOWER
Cleaning Mower
The underside of the mower deck should be cleaned 
after each use to prevent any build-up of grass 
clippings, leaves, dirt, or other debris. If this debris is 
allowed to accumulate, it will result in rust and 
corrosion.
NOTE:  We do not recommend the use of pressure
washers or garden hose to clean your unit. These may
cause damage to electric components, spindles,
pulleys, bearings, or the engine. The use of water will
result in shortened life and reduce serviceability.
Disconnect spark plug wire.
Drain the gasoline from the lawn mower, or place a 
piece of plastic under the gas cap.
Tip the mower so that it rests on the housing. Keep 
the side with the air cleaner facing up. Hold the 
mower firmly.
Scrape and clean the underside of the deck with a 
suitable tool. Do not spray with water. 
Put the mower back on its wheels on the ground. If 
you had put plastic under the gas cap, make sure to 
remove it now.
Engine Care
A list of key maintenance jobs required for good 
performance by the mower is given below. Follow the 
accompanying engine manual for detailed list and 
instructions. 
Change engine oil regularly, as instructed in the 
engine manual. Check oil level before starting 
engine every time.
Service foam filter in the air cleaner every 25 hours 
of use and replace the paper filter component every 
100 hours. You may have to service the air filter 
more frequently if you are operating the mower 
under extremely dusty conditions.
Clean the engine periodically. Remove dirt and 
debris with a cloth or brush. 
Clean the spark plug and reset the gap to .030” at 
least once a season. Refer to the engine manual for 
correct spark plug type.
Inspect muffler periodically, and replace if 
necessary. Damaged mufflers or spark arresters 
can create a fire hazard. Make sure to avoid muffler 
and surrounding areas while the mower engine is 
hot because temperature of these areas of the 
engine may exceed 150
o
 F. 
Lubrication 
Refer to the lubrication chart in Figure 16.
Blade Control Handle
Lubricate the pivot points on the blade control 
handle at least once a season with light oil. The 
blade control must operate freely in both directions. 
Wheels
Lubricate the wheels and bearings, if so equipped, 
at least once a season with light oil or engine oil. 
Also, if the wheels are removed for any reason, 
lubricate the surface of the axle bolt and the inner 
surface of the wheel with light oil. 
Rear Discharge Door
Lubricate the torsion spring and the pivot point on 
each end of the rear discharge door using a light oil. 
This will prevent rusting of the discharge door.
Engine
Follow the engine manual instructions and 
recommended schedule for lubricating engine 
components.

WARNING: 
Always stop the engine and 
disconnect the spark plug wire before

adjustments on your lawn mower.
WARNING: 
Never tip the mower more than 
90 degrees in any directions and do not leave
