After the first two (2) hours of mowing, change the oil

You may need to
change the oil more often under dusty, dirty conditions.

Fill fuel tank, Use fresh, clean, regular unleaded
gasoline with a minimum of 87 octane. Do not mix oil
with gasoline. Purchase fuel in quantities that can be
used within 30 days to assure fuel freshness..
WARNING:
Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or methanol) can
attract moisture which leads to separation and formation of
scids during storage. Acidic gas can damage the fuel
system of an engine while in storage, To avoid engine
problems, the fuel system should be emptied before storage of 30 days or longer. Drain the fuel tank, start the
engine and let it run until fue! lines and carburetor are
empty. Use fresh fuel next season. See Storage Instructions for additional information.
Never use engine or
carburetor cfeaner products in fuel tank or permanent
damage may occur.

Under certain conditions, such as very ta!l grass, itmay
be necessary to raise the height of cut to reduce
pushing effort and to keep from overloading the engine
and leaving clumps of grass clippings.
For extremely heavy cutting, reduce the width of cut by
overlapping previously cut path and mow Slowly,
For better grass bagging and most cutting conditions,
the engine speed should be set in the high (_)
position.
When using a rear discharge lawn mower in moist,
heavy grass, clumps of cut grass may not enter the
grass catcher. Reduce ground speed (pushing speed)
and/or run the lawn mower over the area a secOnd time.

FIG. t2

MULCHING

If a trail of clippings is left on the right side of a rear
discharge mower, mow in a clockwise direction with a
small overlap to collect the clippings on the next pass.

IMPORTANT:
FOR BEST PERFORMANCE,
KEEP
MOWER HOUSING FREE OF BUILT-UP GRASS AND
TRASH.
SEE
"CLEANING '
IN
CUSTOMER
RESPONSIBILiTiES SECTION OF THIS MANUAL.

Pores in ctoth grass catchers can become filled with dirt
and dustwith use and catchers will collect less grass.
To prevent this_ regularly hose catcher off with water
and let dry before using.
Keep top of engine around starter clear and ctean of
grass clippings and chaff. This will help engine airflow
and extend engine life.

10•

The special mulching blade will recut the'grass clippings many times and reduce them in size so that as
they fall onto the lawn they will disperse into the grass
and not be noticed. Also, the mulched grass wil!
biodegrade quickly to provide nutrients for the !awn.
Always mulch with your highest engine (blade) speed
as this will provide the best recutting action of the,
blades.

Avoid cutting your lawn when it is wet. Wet grass tends
to form clumps and interferes with the muiching action.
The best time to mow your lawn is the early afternoon,
At this time the grass has dried and the newly cut area
wili net be exposed to the direct sun.
For best results, adjust the lawn mower cutting height
so that the lawn mower cuts off only the top one-third
of the grass blades (See Fig. 12). tf the fawn is
overgrown it will be necessary to raise the height of cut
to reduce pushing effort and to keep from overloading
the engine and leaving clumps of rnulched grass. For
extrer_ely heavy mulching, reduce your width of cut by
overlapping previously cut path and mow slowly:

Certain types of grass and grass conditions may require that an area be mulched a second time to completely hide the clippings. When doing a second cut,
mow across or perpendicular to the first cut path.

Change your cutting pattern from week to week. Mow
north tOsouth one week then change to east to west the
next week. This will help prevent matting and graining
of the lawn.

possible engine damage from running low on oil.
Change the oil after the first two hours of operation and
every 25 hours thereafter or at least once a year if the lawn
mower is not used for 25 hours in one y®ar.

NOTE:
Fuel stabilizer is an acceptable alternative in
minimizing the formation of fuel gum deposits during storage. Add stabilizer to gasoline in fuel tank or storage
container. Always follow the mix ratio found on stabilizer
container. Run engine at least 10 minutes after adding
stabilizer to allow the stabilizer to reach the carburetor. Do
not drain the gas tank and carburetor if using fuel stabilizer.
