OIL
Your lawnmower isshippedwithoutoilin
theengine.
• Be sum moweris leveland area aroundoU
fillisofean.
• Remove engine oil plug and fill to the
top of slot in filler hole.
NOTE: Allow oil to settle down into engine
for accurate reading.
• Enginehoids 20ozs. of oil. Fortypeand
grade ofoilto use,see "ENGINE" in
Maintenancesectionofthis manual.
• Pouroil slowly. Do notoverfill.
• Check oillevelbeforeeach use. Addoil if
needed.
• Change theoil afterevery25 hoursof
operationor each season. You may need
tochange the oilmore oftenunderdusty,
dirtyconditions.
ADD GASOMNE
• RII fuel tank. Use fresh, clean, regular
urdeadedgasolinewitha minimumof 87
octane. Do notmixoilwith gasoline.
Purchasefuel in quantitiesthatcan be
usedwithin30 daysto assurefuel
freshness.
AWARNING: 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 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. See Storage Instructionsfor
additional information, Never use engine
or carburetor cleaner products in the fuel
tank or permanent damage may occur.
_CAUTION: Fill to bottom of gas tank
fillerneck. 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 tryingto start.
Use a firm push. This step is not
usually necessary when starting an
engine which has already run for a few
minutes.
• 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.

MOWINGTIPS
• 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
(pushing speed) and/or run the lawn
mower over the area a second time.
• If a trail of clippings is lefton the right
side of a rear discharge mower, mow i=
a clockwise direotion 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 willcollect less gras_
To prevent this, regularly hose catcher
off with water and let dry before using.
• Keep top of engine around starter clea
and clean of grass clippings and chaff.
This will help engine air flow and
extend engine life.

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 warranty,
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,
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").
LUBRICATION CHART

IMPORTANT: Do not oil or grease plastic
wheel bearings. Viscous lubricants will attract
dust and dirtthat willshorten the life of the self
lubricating bearings. If you feel they must be
lubricated, use only a dry, powdered graphite
type lubricant sparingly.

parts such as carburetor, f fuel filter,fuel hose
or tank dudng 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 adds during storage. Acidic gas
can damage the fuel system of an engine
while in storage.
• Drain the fuel tank.
• Stad the engine and let itrun until the fuel
lines and cerburetor 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
aitemative in minimizing the formation of fuel
gum deposits during storage. Add stabilizer
to gasoline in fuel tank or storage container.
Always follow the mix ratiofound 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.
