FUEL SYS TEM
IMPORTANT: It is important to prevent gum
deposits from forming in essential fuel system
parts such as carburetor, fuel fi lter, fuel hose,
or tank during storage. 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 car bu re tor are empty.
• Never use engine or carburetor cleaner
prod ucts in the fuel tank or permanent
damage may occur.
• Use fresh fuel next season.

NOTE: Fuel stabilizer is an acceptable alternative in min i miz ing the formation of fuel
gum deposits during stor age. Add stabilizer
to gasoline in fuel tank or storage container.
Always follow the mix ratio found on stabilizer
container. Run engine at least 10 min utes
after adding stabilizer to allow the stabilizer
to reach the car bu re tor. Do not drain the gas
tank and car bu re tor if using fuel stabilizer.
ENGINE OIL
Drain oil (with engine warm) and replace
with clean oil. (See “ENGINE” in the Maintenance section of this manual).
CYLINDER
• Remove spark plug.
• Pour one ounce (29 ml) of oil through
spark plug hole into cylinder.
• Pull starter handle slowly to dis trib ute oil.
• Replace with new spark plug.
BATTERY (IF EQUIPPED)
Disconnect the battery from the engine
connector and charge battery 48 hours.
OTHER
• Do not store gasoline from one sea son
to another.
• Replace your gasoline can if your can
starts to rust. Rust and/or dirt in your
gasoline will cause problems.
• If possible, store your unit indoors and
cover it to protect it from dust and dirt.
• Cover your unit with a suitable pro tec tive
cover that does not retain mois ture. Do
not use plastic. Plas tic cannot breathe,
which allows con den sa tion to form and
will cause your unit to rust.
IMPORTANT: Never cover mower while
engine and exhaust areas are still warm.
CAUTION: Never store the lawn mow er
with gaso line in the tank in side a build ing
where fumes may reach an open fl ame
or spark. Allow the engine to cool before
storing in any en clo sure.
34
SAFETY RULES
• Stop the engine (motor) whenever you
leave the equip ment, before clean ing the
mower or unclogging the chute.
• Shut the engine (motor) off and wait until
the blade comes to complete stop before
removing grass catcher.
• Mow only in daylight or good artifi cial
light.
• Do not operate the machine while under
the infl uence of alcohol or drugs.
• Never operate machine in wet grass.
Always be sure of your footing: keep a
fi rm hold on the handle; walk, never run.
• Disengage the self-propelled mech a nism or drive clutch on mowers so
equipped before starting the engine.
• If the equipment should start to vi brate
abnormally, stop the engine (motor) and
check immediately for the cause. Vibration is generally a warning of trouble.
• Always wear safety goggles or safe ty
glasses with side shields when op er at ing
mower.
II. SLOPE OPERATION
Slopes are a major factor related to slip &
fall accidents which can result in severe
injury. All slopes require extra caution. If
you feel uneasy on a slope, do not mow it.
DO:
• Mow across the face of slopes: nev er
up and down. Exercise extreme caution
when changing direction on slopes.
• Remove obstacles such as rocks, tree
limbs, etc.
• Watch for holes, ruts, or bumps. Tall
grass can hide obstacles.
DO NOT:
• Do not trim near drop-offs, ditches or
embankments. The operator could lose
footing or balance.
• Do not trim excessively steep slopes.
• Do not mow on wet grass. Reduced
footing could cause slipping.
III. CHILDREN
Tragic accidents can occur if the op er a tor is not alert to the presence of children.
Children are often attracted to the ma chine
and the mowing activity. Never assume
that children will remain where you last
saw them.
• Keep children out of the trimming area
and under the watchful care of an oth er
re spon si ble adult.
• Be alert and turn machine off if chil dren
enter the area.
• Before and while walking back wards,
look behind and down for small chil dren.
• Never allow children to operate the
machine.
• Use extra care when approaching blind
corners, shrubs, trees, or other objects
that may obscure vision.
WARNING: CHILDREN CAN BE
INJURED BY THIS EQUIPMENT. The
American Academy of Pediatrics recommends that children be a minimum of 12
year of age before operating a pedestrian
controlled lawn mower and a minimum of
16 years of age before operating a riding
lawn mower.
• When loading or unloading this machine,
do not exceed the maximum recommended operation angle of 15°.
• Wear proper Personal Protective Equip-
ment (PPE) while operating this machine, including (at a minimum) sturdy
footwear, eye protection, and hearing
protection. Do not mow in shorts or
open toed footwear.
Always let someone know you are outside
mowing.
IV. SAFE HANDLING OF GASOLINE
Use extreme care in handling gasoline.
Gasoline is extremely fl ammable and the
vapors are explosive.
• Extinguish all cigarettes, cigars, pipes
and other sources of ignition.
• Use only an approved container.
• Never remove gas cap or add fuel with
the engine running. Allow engine to cool
before refueling.
• Never refuel the machine indoors.
• Never store the machine or fuel contain-
er where there is an open fl ame, spark
or pilot light such as a water heater or
on other appliances.
• Never fi ll containers inside a vehicle, on
a truck or trailer bed with a plastic liner.
Always place containers on the ground
away from your vehicle before fi lling.
• Remove gas-powered equipment from
the truck or trailer and refuel it on the
ground. If this is not possible, then
refuel such equipment with a portable
container, rather than from a gasoline
dispenser nozzle.

Page 4
SAFETY RULES
• Keep the nozzle in contact with the rim
of the fuel tank or container opening at
all times until fueling is complete. Do
not use a nozzle lock-open device.
• If fuel is spilled on clothing, change
clothing immediately.
• Never overfi ll fuel tank. Replace gas
cap and tighten securely.
V. GENERAL SERVICE
• Never run a machine inside a closed

MAINTENANCE
GEAR CASE
• To keep your drive system working
properly, the gear case 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 case is fi lled 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.
ENGINE
Read the maintenance section of your
engine manual.
LUBRICATION
Change the oil after the fi rst two hours of
operation and every 25 hours there af ter or
at least once a year if the lawn mower is
not used for 25 hours in one year. Refer to
engine manual.
TO CHANGE ENGINE OIL
(SEE ENGINE MANUAL)
• Be sure lawn mower is on level surface.
• Oil will drain more freely when warm.
• Catch oil in a suitable container.
• For engines without dipstick, re move
bottom oil drain plug.
• For engines with oil fi ll cap/dipstick,
remove bottom drain plug or remove engine oil cap and turn mower on its side.
• After oil has drained completely, re place
oil drain plug and tighten se cure ly.
• Refi ll engine with oil. Pour slowly. Do
not overfi ll.
• Fill to top of slot inside of fi ller hole or
to “FULL” line on dipstick on models so
equipped. Keep oil at proper level.
AIR FILTER
Your engine will not run properly and may
be damaged by using a dirty air fi lter.
Clean the element after every 25 hours
of operation or every season. Replace
the air fi lter every 100 hours of operation
or every season, whichever occurs fi rst.
Service air cleaner more often under dusty
conditions. See the maintenance section
of your engine manual.
IN-LINE FUEL FILTER (KOHLER or B&S
PRO / ENDURANCE ENGINES ONLY)
The fuel fi lter should be replaced once
each season. If fuel fi lter becomes
clogged, ob struct ing fuel fl ow to car bu re tor,
re place ment is re quired.
1. With engine cool, remove fi lter and plug
fuel line sec tions.
2. Place new fuel fi lter in position in fuel
line with arrow pointing towards carburetor.
3. Be sure there are no fuel line leaks and
clamps are properly positioned.
4. Immediately wipe up any spilled gasoline.
Clamp Clamp
Fuel
Filter
MUFFLER
Inspect and replace corroded muffl er as it
could create a fi re hazard and/or damage.
SPARK PLUG
Replace spark plug at the beginning of
each mowing season or after every 100
hours of operation, whichever occurs fi rst.
Set spark plug gap according to engine
manual specifi cations.
CLEANING
IMPORTANT: For best performance, keep
mower housing free of grass build-up and
trash. Clean the underside of your mower
after each use.
• Clean the underside of your lawn mower
by scraping to remove buildup of grass
and trash.
• Clean engine often to keep trash from
accumulating. A clogged engine runs
hotter and shortens engine life.
• Keep fi nished surfaces and wheels free
of all gasoline, oil, etc.
We do not recommend using a garden
hose to clean the outside of your lawn
mower unless the electrical system, muffl er, air fi lter, and carburetor are covered
to keep water out. Water in engine can
shorten engine life.

MAINTENANCE
BLADES WITH ROUND HOLE:
• To check blade balance, drive a nail into
a beam or wall. Leave about one inch of
the straight nail ex posed. Place center
hole of blade over the head of the nail.
If blade is balanced, it should remain in
a horizontal position. If either end of the
blade moves downward, sharpen the
heavy end until the blade is balanced.
BLADES WITH “STAR” HOLE:
• To check blade balance, you will need
a 5/8" diameter steel bolt, pin, or a cone
balancer. (When using a cone bal anc er,
follow the in struc tions supplied with

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 war ranty, operator must maintain mower as instructed in this manual.
Some adjustments will need to be made
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,
clean or replace air fi lter element, and
check blade for wear. A new spark plug
and clean/new air fi lter element assures
proper air-fuel mixture and helps your
en gine run better and last longer.
• Follow the Maintenance Sched ule in this
manual.
BEFORE EACH USE
• Check engine oil level.
• Check for loose fasteners.
LUBRICATION
Keep unit well lubricated
(See “LUBRICATION CHART”).
IMPORTANT: Do not oil or grease plastic

MOWING TIPS
CAUTION: Do not use de-thatcher
blade attachments on your mower. Such
attachments are hazardous, will damage
your mower and could void your warranty.
• For most cutting conditions and bet ter
bagging per form ance, the engine speed
should be set in the FAST po si tion.
• Under certain conditions, such as when
mowing very tall grass, raise the mower
height on the fi rst cut to reduce pushing
effort, to avoid over heat ing the engine,
and to avoid leaving clumps of grass
clippings. Make the second cut to the
desired height.
• For extremely heavy cutting, reduce the
width of cut.
• For side discharge lawn mowers, cut in
a coun ter clock wise di rec tion, start ing at
the outside of the area to be cut, in order
to spread grass clip pings more evenly
and to put less load on the engine. To
keep clip pings off of walkways, fl ower
beds, etc., make the fi rst cuts in a clock wise direction.
• 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 grass clipping is left on the
right side of a rear discharge lawn 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 fi lled with dirt and dust with use
and the catcher will collect less grass.
To prevent this, regularly hose catcher
off with water and let dry before use.
FOR MULCHING MOWERS ONLY
- MULCHING MOWING TIPS
IMPORTANT: For best performance, keep
mower housing free of built-up grass and
trash. See "CLEANING" in the Maintenance section of this manual.
• The special mulching blade will recut the
grass clip pings 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 bio de grade quickly to provide
nu tri ents 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 it is wet.
Wet grass tends to form clumps and
in ter feres with the mulch ing action. The
best time to mow your lawn is the early
afternoon. At this time the grass has
dried, yet the newly cut area will not be
exposed to direct sunlight.
• 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 over load ing the engine and leaving
clumps of mulched grass. For ex tremely
heavy grass, reduce your width of cut
by overlapping previously cut path and
mow slowly.
MAX 1/3
• Certain types of grass and grass
con di tions may re quire that an area be
mulched a second time to com pletely
hide the clip pings. When doing a sec ond
cut, mow across (per pen dic u lar) to the
fi rst cut path.
• Change your cutting pattern 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.

• Remove engine oil fi ller plug (oil fi ll cap/
dipstick on models so equipped).
• Slowly add oil. For type and grade of
oil to use, see “ENGINE” in the Maintenance section of this manual.
• Fill to the top of slot in fi ller hole (to
“FULL” line on dipstick on models so
equipped). Do not overfi ll.
• Replace plug (oil fi ll cap/dipstick on
models so equipped) and tighten.
• Check oil level before each use. Add oil
as needed.
• To change oil, see Maintenance section

FILL GASOLINE TANK
• Fill gasoline tank with fresh, clean,
unleaded gaso line. DO NOT USE PREMIUM GASOLINE. BE CARE FUL NOT
TO OVERFILL TANK.
WARNING: Al co hol blended fuels (called
gaso hol or using ethanol or metha nol) can
at tract mois ture which leads to sepa ra tion
and for ma tion of acids during storage. Acidic
gas can damage the fuel system of an en gine
while in stor age. To avoid engine prob lems,
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 car bu re tor are empty. Use fresh
fuel next season. See Stor age In struc tions
