BEFORE STARTING ENGINE
OIL (See Fig_ 7)
Your lawn mower is shipped without oil in the engine.
Be sure mower is level and area around oil fill is clean.
o Remove engine oil cap w/dipstick and fill to the full line
on the dipstick.
Use 20 ozs. of oil. Fortypeandgradeofoilto use, see

Check oil level before each use. Add oil if needed. Fill
to full line on dipstick.
-To read proper level, tighten engine oil cap each time.

o After the first two (2) hours of mowing, change the oil,
and every 25 hours thereafter. You may need to
change the oil more often under dusty, dirty conditions.
GAS (See Fig. 7)
o Fill gasoline tank with fresh, clean, unleaded gasoline,
DO NOT USE PREMIUM GASOLINE. BE CAREFUL
NOT TO OVER FILL TANK.
WARNING: Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or methanol) can
attract moisture which leads to separation and formation of
acids 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 stor-
age of 30 days or longer. Drain the fuel tank, start the
engine and let it run until fuel lines and carburetor are
empty. Use fresh fuel next season. See Storage Instruc-
tions for additional information. Never use engine or
carburetor cleaner products in fuel tank or permanent
damage may occur.

trying to start. Use afirm push. This step is not usually
necessary when starting an engine which has already
run for a few minutes.
- Hold operator presence control bar clown to the handle

MOWING TiPS
•Undercertain conditions,such as very tall 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
and raise the rear of the lawn mower housing one (1)
wheel adjuster setting higher than the front for better
discharge of grass,
•Forside discharge mowers, cutting in a counter-clock-
wise direction, starting at the outside of the area to be
cut, spreads grass clippings more evenly and puts less
load on the engine. To keep clippings off of walkways,
flower beds, etc. make the first cuts in a clockwise
direction.
• Keep top of engine around starter clear and clean of
grass clippings and chaff. This will help engine airflow
and extend engine life,

OPERATIO
MULCHING MOWING TiPS
IMPORTANT: FOR BEST PERFORMANCE, KEEP
MOWER HOUSING FREE OF BUILT-UP GRASS AND
TRASH. CLEAN UNDERStDE OF MOWER HOUSING
AFTER EACH USE. SEE"CLEANING" IN CUSTOMER
RESPONSIBILITIES SECTION OF THIS MANUAL.
o The special mulching blade will recur the grass c_ip-
pings many times and reduce them in size so that as
they fail onto the lawn they will disperse into the grass
and not be noticed. Also, the mulched grass will
biodegrade quickly to provide nutrients for the lawn,
Always mulch with your highest engine (blade) speed
as this will provide the best recutting action of the
blades.
= Avoid cutting your lawn when itiswet. Wet grass tends
to form clumps and interferes with the mulching action.
The best time to mow your lawn isthe early afternoon.
At this time the grass has dried and the newly cut area
will not 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. 8). If the lawn is
overgrown itwill be necessary to raise the height of cut
to reduce pushing effort and to keep from overloading
the engine and leaving clumps of mulched grass. For
extremely heavy mulching, reduce your width of cut,
mow slowly and raise the rear of the lawn mower one
wheel adjuster setting higher than the front.
- Certain types of grass and grass conditions may re-
quire 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 to south one week then change to east towest the
next week. This will help prevent matting and graining
of the lawn.
