are familiarwith the instructions, to oper-
ate the machine.
• Clear the area of objects such as rocks,
toys, wire, bones, sticks, etc., which
could be picked up and thrown by blade.
Be sure the area is clear of other people
before mowing. Stop machine if anyone
enters the area.
Do not operate the mower when bare-
foot or wearing open sandals. Always
wear substantial foot wear.
Do not pull mower backwards unless
absolutely necessary. Always look down
and behind before and while moving
backwards.
• Never direct discharged material toward
anyone. Avoid discharging material
against a wall or obstruction. Material
may richochet back toward the opera-
tor. Stop the blade when crossing gravel
surfaces.
• Do not operate the mower without
proper guards, plates, grass catcher or
other safety protective devices in place.
• See manufacturer's instructions for
proper operation and installation of
accessories. Only use accessories ap-
proved by the manufacturer.
• Stop the blade(s) when crossing gravel
drives, walks, or roads.
• Stop the engine (motor) whenever you
leave the equipment, before cleaning 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 artificial
light.
• Do not operate the machine while under
the influence of alcohol or drugs.
• Never operate machine in wet grass.
Always be sure of your footing: keep a
firm hold on the handle; walk, never run.
• Disengage the self-propelled mech-
anism or drive clutch on mowers so
equipped before starting the engine.
• If the equipment should start to vibrate
abnormally, stop the engine (motor) and
check immediately for the cause. Vibra-
tion is generally a warning of trouble.
• Always wear safety goggles or safety
glasses with side shields when operating
mower.
il, SLOPE OPERATION
Slopes are a major factor related to slip &
fall accidents which can result in severe in-
jury. All slopes require extra caution. If you
feel uneasy on a slope, do not mow it.
DO:
• Mow across the face of slopes: never
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 foot-
ing could cause slipping.
i11. CHILDREN
Tragic accidents can occur if the operator
is not alert to the presence of children.
Children are often attracted to the machine
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 another
responsible adult.
• Be alert and turn machine off if children
enter the area.
• Before and while walking backwards,
look behind and down for small children.
• Never allow children to operate the ma-
chine.
• Use extra care when approaching blind
corners, shrubs, trees, or other objects
that may obscure vision.
IV. SAFE HANDLING OF GASOLINE

BEFORE STARTING ENGINE
ADD OIL
Your lawnmower is shipped without oil in
the engine. For type and grade of oil to
use, see "ENGINE" in the Maintenance
section of this manual.
A CAUTION: DO NOT overfill engine with
oil, or it will smoke heavily from the muffler
on startup.
1. Be sure lawnmower is level.
2. Remove oil dipstick from oil fill spout.
3. You receive a container of oil with the
unit. Slowly pour the entire container
down the oil fill spout into the engine.
NOTE: Initial oil fill requires only 18 oz.
due to residual oil in engine from the
manufacturers 100% quality testing. When
changing oil you may need 20 oz.
4. Insert and tighten dipstick.
IMPORTANT:
• Check oil level before each use. Add oil
if needed. Fill to full line on dipstick.
• 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. See "TO
CHANGE ENGINE OIL" in the Mainte-
nance section of this manual.
ADD GASOLINE
• Fill fuel tank to bottom of tank filler neck.
Do not overfill. Use fresh, clean, regular
unleaded gasoline with a minimum of 87
octane. Do not mix oil with gasoline. Pur-
chase fuel in quantities that can be used
within 30 days to assure fuel freshness.
• i, CAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open flame.

TO STOP ENGINE
• To stop engine, release operator pres-
ence control bar.
TO START ENGINE
NOTE: Due to protective coatings on the
engine, a small amount of smoke may be
present during the initial use of the prod-
uct and should be considered normal.
1. 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.
2. Hold operator presence control bar
down to the handle and pull starter
handle quickly. Do not allow starter rope
to snap back.
NOTE: In coolerweather 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
_i, CAUTION: Do not use de-thatcher
blade attachments on your mower. Such
attachments are hazardous, will damage
your mower and could void your warranty.
• 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 cut-
ting conditions, the engine speed should
be set in the FAST position.
• For side discharge lawn mowers, cutting
in a counter-clockwise direction, start-
ing 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 clock-
wise direction.
• Pores in cloth grass catchers can be-
come 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 the
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 biodegrade quickly
to provide nutrients for the lawn. Always
mulch with your highest engine (blade)
speed as this will provide the best recut-
ting 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, yet the newly cut area will not be
exposed to direct sunlight.
For bestresults, adjustthe lawnmower
cutting heightso thatthe lawn mower
cuts offonlythe top one-thirdof the
grass blades, Ifthe lawnis overgrownit
will be necessaryto raisethe heightof
cut to reducepushingeffort and tokeep
fromoverloadingthe engineand leaving
clumpsof mulchedgrass,For extremely
heavygrass,reduceyourwidth of cut
byoverlappingpreviouslycutpath and
mow slowly,
• Certain types of grass and grass conditions
may require that an area be mulched a sec-
ond time to completely hide the clippings.
When doing a second cut, mow across
(perpendicular) to the first 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.

GRASS CATCHER
(If purchased as an accessory)
• The grass catcher may be hosed with
water, but must be dry when used.
• Check your grass catcher often for dam-
age or deterioration. Through normal
use it will wear. If catcher needs replac-
ing, replace only with approved replace-
ment catcher shown in the Repair Parts
section of this manual. Give the lawn
mower model number when ordering.
ENGINE
LUBRICATION
Use only high quality detergent oil rated with
API service classification SG-SL. Select the
oil's SAE viscosity grade according to your
expected operating temperature.
SAE VISCOSITY GRADES t
40
NOTE: Although multi-viscosity oils (5W30,
10W30 etc.) improve starting in cold weather,
they will result in increased oil consumption
when used above 32°F. Check your engine
oil level more frequently to avoid possible
engine damage from running low on oil.
Change the oil after every 25 hours of opera-
tion orat least once a year if the lawn mower
is not used for 25 hours in one year.
Check the crankcase oil level before
starting the engine and after each five (5)
hours of continuous use. Tighten oil plug
securely each time you check the oil level.
TO CHANGE ENGINE OIL
1. Disconnect spark plug wire from spark
plug and place wire where it cannot
come in contact with plug.
2. Be sure lawn mower is on level surface.
NOTE: Oil will drain more freely when
warm. Catch oil in a suitable container.
3. Remove bottom oil drain plug.
"___ SEAL WHEN
4. Afteroil has drained completely, replace
oil drain plug and tighten securely.
5. Fill engine with oil. (See "ADD OIL" in
the Operation section of this manual).
6. Reconnect spark plug wire to plug.
AIR FILTER
Your engine will not run properly and may
be damaged by using a dirty air filter.
