I. GENERAL OPERATION
Read, understand, and follow all instructions on the machine and in the
manual(s) before starting. Be thoroughly familiar with the controls and the proper
use of the machine before starting.
Do not put hands or feet near or under rotating parts. Keep clear of the dis-
charge opening at all times.
Only allow responsible individuals, who are familiar with the instructions, to
operate the machine.
Clear the area of objects such as rocks, toys, wire, bones, sticks, etc., which could be picked up and thrown by the
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.
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 and walk; never run.
Disengage the self-propelled mech- anism or drive clutch on mowers so
equipped before starting the engine (motor).
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 oper- ating mower.
II. SLOPE OPERATION
Slopes are a major factor related to slip and fall accidents which can result in
severe injury. All slopes require extra cau- tion. 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.
III. 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. SERVICE
Use extra care in handling gasoline and
other fuels. They are flammable and vapors are explosive.
-Use only an approved container.
-Never remove gas cap or add fuel with the engine running. Allow engine to cool before refueling.
Do not smoke.
-Never refuel the machine indoors.
-Never store the machine or fuel
container inside where there is an open flame, such as a water heater.
Never run a machine inside a closed area.
Never make adjustments or repairs with the engine (motor) running. Disconnectthe spark plug wire, and keep the wire away from the plug toprevent accidental starting.

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. 4[_CAUTION: DO NOT overfill engine with oil, or itwill 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.
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 OIC' 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. Purchase fuel in quantities that can be used within 30 days to assure fuel fresh-
ness.
CAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near
A an open flame.
CAUTION: Alcohol blended fuels
(called gasohol or using ethanol or metha-
nol) 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. Empty 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 Instructions for additional information. Never use engine
or carburetor cleaner products in the fuel tank or permanent damage may occur.

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 cooler weather it may be neces- sary 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 attempt- ing 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 clip-
pings. _tmay also be necessary to re-
duce 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.
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 left on the right side of a rear discharge mower, mow in
a clockwise direction with a small over-
lap to collect the clippings on the next pass.
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 best results, adjust the lawn mower cutting height so that the lawn mower cuts off only the top one-third of the grass blades. Ifthe 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 grass, reduce your width of cut by overlapping previously cut path and
mow slowly.
MAXI_
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 sec-
ond 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.

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 unit as instructed in this manual. Some adjustments will need to be made
periodically to properly maintain your unit.
At least once a season, check to see if you should make any of the adjustments
described in the Service and Adjustments section of this manual.
At least once a year, replace the spark plug, clean or replace air filter element and check blade for wear. A new spark plug and clean/new air filter element assure proper air-fuel mixture and help 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 "LUBRICATION CHART").

See "ENGINE" in Maintenance section.
IMPORTANT: Do not oil or grease plastic wheel bearings. Viscous lubricants will
attract dust and dirtthatwill shorten the life of the self-lubricating bearings. If you feel they
must be lubricated, use only a dry, powdered
11graphite type lubricant sparingly.
LAWN MOWER
Always observe safety rules when per- forming any maintenance.
TIRES
Keep tires free of gasoline, oil, or insect control chemicals which can harm rubber.
Avoid stumps, stones, deep ruts, sharp objects and other hazards that may cause tire damage.
BLADE CARE
For best results, mower blade must be kept
sharp. Replace bent or damaged blades.
TO REMOVE BLADE
1. Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with spark plug.
2. Turn lawn mower on its side. Make sure air filter and carburetor are up.
3. Use a wood block between blade and mower housing to prevent blade from
turning when removing blade bolt.
NOTE: Protect your hands with gloves
and/or wrap blade with heavy cloth.
4. Remove blade bolt by turning counter- clockwise.
5. Remove blade and attaching hardware (bolt, lock washer and hardened washer).
TO REPLACE BLADE
1. Position blade on the blade adapter aligning the two (2) holes in the blade with the raised lugs on the adapter.
2. Be sure the trailing edge of blade (oppo- site sharp edge) is up toward the engine.
3. Install the blade bolt with the lock washer and hardened washer into
blade adapter and crankshaft.
4. Use block of wood between blade and lawn mower housing and tighten the
blade bolt, turning clockwise.
The recommended tightening torque is
35-40 ft. Ibs.
IMPORTANT: Blade bolt is heat treated. If bolt needs replacing, replace only with
approved bolt shown in the Repair Parts section of this manual.

Key _ keyway
Blade
TO SHARPEN BLADE NOTE: We do not recommend sharpening
the blade - but if you do, be sure the blade is balanced.
Care should be taken to keep the blade balanced. An unbalanced blade will
cause eventual damage to lawn mower or engine.
The blade can be sharpened with a file or on a grinding wheel. Do not attempt to sharpen while on the mower.
To check blade balance, drive a nail into a beam or wall. Leave about one inch of
the straight nail exposed. 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.
GRASS CATCHER
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 SF-SJ. Select the oil's SAE viscosity grade according to your
expected operating temperature.

F -20 0 30 32 40 60 80 100
c -3o -2; -_; ; 1; _o 3o 40
TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, these multi-viscosity oils 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.
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.
