BEFORE STARTING
OIL

ENGINE

Your lawn mower is shipped without oil in the
engine.
• Be sure mower is level and area around oil
fill is clean.
• Remove engine oil cap and fillto the full
line on the dipstick.
NOTE: Allow oil to settle down into
engine for accurate dipstick reading.

• Engine holds 20ozs. of oil. Fortypeand
grade of oil to use, see "ENGINE" in
Maintenance section of this manual.
• Pour oil slowly. De 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.
ADD GASOUNE
NOTE: Before filling fuel tank, remove
and discard the debris plug that is inside
the tank.
• 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.
A, WARNING:
Experience indicates that
alcohol blended fuels (catted 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 fuel tank, start the
engine and let it run until fuel lines and
carburetor are empty. Use fresh fuel next
season. See Storage Instructions for
additional information.
Never use engine
or carburetor cleaner products in fuel tank
or permanent
damage may occur.
_I=CAUTION:
Fill to bottom of gas tank
filler neck. Do not overfill. Wipe off any
spilled oil or fuel. Do not store, spill or use
gasoline near an open flame.

TO START

ENGINE

• To start a cold engine, push primer
three (3) times before trying to start.
Use a firm push. This step is not
usually necessary when starting an
engine which has already run for a few
minutes.
• Move throttle control lever to fast
position.
• Hold operator presence control bar
down to the handle and pull starter
handle 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.
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.
• For side discharge lawn mowers,
cutting in a counter-clockwise 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.
• Pores in cloth grass catchers can
become filled with dirt and dust with

Engine oil cap

cap

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.

(Discard
debris plug
inside)

MULCHING MOWING TIPS

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

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 d_erse
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 recurring action of the
blades.
• Avoid cutting your lawn when it is wet. Wet
grass tends to form clumps 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, ad)ust the lawn mower

change to east to west the next week. This
will help prevent matting and graining of
the lawn.

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 engine is running too fast or
too slow, take your mower to an authorized service center for repair and
adjustment.
CARBURETOR
Your carburetor has a non-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
the proper engine speed.
Overspeeding
the engine above the factory high speed
scan be dangerous,
if you think the
engine-governed
high speed needs
adjusting, contact your nearest authorized
service center, which has proper equipment and experience
to make any
necessary
adjustments.

• Squeeze lower handle in and position
holes onto mounting pins on handle
bracket.
• Reassemble
upper handle and all
parts removed from lower handle.

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.
LAWN MOWER

of time, clean it thoroughly, remove all dirt,
grease, leaves, etc. Store in a clean, dry
area.

ENGINE
FUELSYSTEM
IMPORTANT: It is important to prevent gum
deposits from forming in essential fuel system
parts such as carburetor, 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 if 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
altemative 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.
ENGINEOIL
Drain oil (with engine warm) and replace with
clean engine oil. (See"ENGINE"
inthe
Maintenance section of this manual).
