BEFORE STARTING ENGINE
OIL
Your lawn mower is shipped without oil in the
engine.
• Be sure mower is level and area around oil
fill is dean.
•Remove engine oil cap and fill to the full
line on the dipstick.
NOTE: Allow oil to settle down into engine
for accurate dipstick reading
• Engine holds 27 ozs. of oil. For type and
grade of oil to use, see "ENGINE" in
Maintenance section of this manual.
• Pour oil slowly. Do not over fill.
• 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.
• Reinstall engine oil cap and tighten.
• Change the oil after every 25 hours of
operation or each season. You may need
to change the oil more often under dusty,
dirty conditions.
GAS
• Fill fuel tank. Use fresh, clean, regular
unleaded gasoline with a minimum of 87
octane. Do not mix oil with gasoline.
Purchase fuel in quartzes that can be
used within 30 days to assure fuel
freshness.
WARNING: Experience indicates that
alcohol blended fuels (called gasohot 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
storage of 30 days or longer. Drain the gas
tank, start the engine and let it run until the
fuel lines and carburetor are empty. Use
fresh fuel next season. Sea Storage
InstTuctions for additional information. Never
use engine or carburetor cleaner products in
the fuel tank or permanent damage may
occur.

quickly. Do not allow starter rope to snap
back.
• To stop engine, release operator presence
control bar.
NOTE: In cooler weather it may be
necessary to repeat priming steps. In
warmer weather over priming may cause
flooding and engine will not start. If you
do flood engine, wait a few minutes
before attempting to start and do not
repeat priming steps.

![](asset-9.png)
MOWING TIPS
•Under certain conditions, such as very
tall grass, it may 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. It
may also be necessary to reduce
ground speed and/or run the lawn
mower over the area a second time,
• 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 fast 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 (push-
ing speed) and/or run the lawn mower
over the area a second time.
•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.
•Pores in cloth grass catchers can
become filled with dirt and dust with 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 clean of grass clippings and chaff.
This will help engine air flow and extend
engine life.
MULCHING MOWING TIPS
IMPORTANT: For best performance, keep
mower housing free of built-up grass and
trash. See "Cleaning" in Maintenance section
of this manual.
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 will
biedegrade quickly to provide nutrients for
the lawn. Always mulch with your highest
engine (blade) speed as this will provide the
best recuttJng action of the blades.
Avoid cutting your lawn when it is wet. Wet
grass tends to form dumps and interferes
with the mulching action. The best time to
mow your lawn is the 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.
If the lawn 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 mulched
grass. For extremely 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 pattem from week to
week. Mow north to south one week then
change to east to west the next week. This
will help prevent matting and graining of the
lawn.

periodically to properly maintain your unit.
All adjustments in the Service and
Adjustments section of this manual should
be checked at least once each season.
• Once a year, replace the spark plug,
replace air filter element and check
blade for wear. A new spark plug and
clean/new air filter element assures
proper air-fuel mixture and helps your
engine run better and last longer.
• Follow the maintenance schedule in this
manual.
BEFORE EACH USE
• Check engine oil level.
• Check for loose fasteners.
LUBRICATION
Keep unit well lubricated (See "LUBRICA-
TION CHART").

spark plug.
• Turn lawn mower on its side. Make sure air
filter end carburetor are up. Clean the
underside of your lawn mower by scraping
to remove build-up of grass end trash.
• Clean engine often to keep trash from
accumulating. A dogged engine runs
hotter and shortens engine life.
• Keep finished surfaces end wheels free of
all gasoline, oil,etc.
• We do not recommend using a garden
hose to clean lawn mower unless the
electrical system, muffler, air filter end
carburetor are covered to keep water out.
Water in engine can result in shortened
engine life.
CLEAN UNDER DRIVE COVER
Clean under drive cover at least twice a
season. Scrape unders'de of cover with putty
knife or similar tool to remove any build-up of
trash or grass on underside of drive cover.

ENGINE SPEED
Your engine speed has been factory set.
Do not attempt to increase engine speed
or it may result in personal injury. If you
believe that the engine is running too fast
or too slow, take your lawn mower to an
authorized service center for repair and

Your carburetor has anon-adjustable
fixed main jet for mixture control. If your
engine does not operate properly due to
suspected carburetor problems, take your
lawn mower to an authorized service
center for repair and/or adjustment.
IMPORTANT: never tamper with the
engine governor, which is factory set for
proper engine speed. Overspeeding the
engine above the factory high speed
setting can be dangerous, if you think the
engine-governed high speed needs
adjusting, contact your nearest authorzed
service center, which has proper
equipment and experience to make any
necessary adjustments.

Immediately prepare your lawn mower for
storage at the end of the season or if the unit
will not be used for 30 days or more.
LAWNMOWER
When lawn mower is to be stored for a period
of time, clean it thoroughly, remove all dirt,
grease, leaves, etc. Store in a clean, dry area,
•Clean entire lawn mower (See "CLEAN-
ING" in the Maintenance section of this
manual).
• Lubricate as shown in the Maintenance
section of this manual.
•Be sure that all nuts, bolts, screws, and pins

FUELSYSTEM
IMPORTANT: It is important to prevent gum
deposits from forming in essential fuel system
parts such as carburetor, f fuel filter, fuel hose
or tank during storage. Also, 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.
• Drain the fuel tank.
• Start the engine and let it run until the fuel
lines and carburetor are empty.
• Never use engine or carburetor cleaner
products in the fuel tank or permanent
damage may occur,
• Use fresh fuel next season,
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
a_er adding stabilizer to allow the stabilizer to
reach the carburetor. Do not drain the gas
tank and carburetor if using fuel stabilizer.
