General recommendations

The warranty on this lawn mower does not cover items
that have been subjected to operator abuse or
negligence. To receive full value from the warranty,
operator must maintain mower as instructed in this
manual. Some adjustments will need to be made
periodically to properly maintain your unit. At least once a
season, check to see if you should make any of the
adjustments described in the Maintenance section of this
manual.
• At least once a year, replace the spark plug, clean or
replace air filter element and check blade for wear. A
new spark plug and clean/new air filter element
assure proper air-fuel mixture and help your engine
run better and last longer.
• Follow the maintenance schedule in this manual.

General inspection

• Check that nuts and screws are tight.

General lubrication

CAUTION! Do not oil or grease plastic wheel bearings.
Viscous lubricants will attract dust and dirt that will
shorten the life of the selflubricating bearings. If you feel
they must be lubricated, use only a dry powdered
graphite type lubricant sparingly.
Keep unit well lubricated.

Cleaning

WARNING! Always disconnect the spark
!
plug before performing maintenance or
service.
• Brush leaves, grass and the like off of the lawn mower.
• Keep finished surfaces / wheels free of gasoline, oil,
etc.
• Keep top of engine around starter clear and clean of
grass clippings and chaff. This will help engine air flow
and extend engine life.
• Clean the underside of your lawn mower by scraping
to remove build-up of grass and trash.
• Do not use a high pressure washer to clean the
machine.
• Never flush water directly on the engine.
• Clean the air intake on the starter. Check the starter
and starter cord.
• When cleaning under the cutting cover, empty the fuel
tank and put the machine on its side with the muffler
down.
CAUTION! With the exception of the water washout port
(if equipped), we do not recommend using a garden
hose to clean the outside of your lawn mower unless the
electrical system, muffler, air filter and carburetor are
covered to keep water out. Water in engine can result in
shortened engine life.
Drive wheels
Check wheels each time before you mow to be sure they
move freely. Clean the wheels if not rotating freely.
1 Remove the bolt.
2 Remove wheels from wheel adjusters.
3 Remove any trash or grass cuttings from inside the
dust cover, pinion and/or drive wheel gear teeth.
4 Replace the wheels.
If after cleaning, the drive wheels do not turn freely,
contact a authorized service workshop.
Grass catcher
3
• Pores in cloth grass catchers can become filled with
dirt and dust with use and the catcher will collect less
grass. To prevent this, regularly hose the grass
catcher off with water and let dry before using.
• Check the grass catcher frequently for wear or
deterioration. Replace if necessary.
Gear cases
• To keep your drive system working properly, the gear
cases and area around the drive should be kept clean
and free of trash build-up. Clean under the drive cover
twice a season.
• The gear cases are filled with lubricant to the proper
level at the factory. The only time the lubricant needs
attention is if service has been performed on the gear
case.
