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.

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.
_l_ 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.
Engine
oil cap
Gasoline
filler cap
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.
i, CAUTION: Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open flame.
i, 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 product and should be considered normal.
NOTE: Your engine is equipped with an automatic choke system. No priming or choking is required before starting.
To start engine, hold operator presence
control bar down to the handle and pull starter handle quickly. Do not allow starter rope to snap back.
MOWING TIPS
CAUTION: Donotuse de-thatcher
bladeattachmentson your mower.Such attachmentsare hazardous,will damage
your mower andcould 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 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 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.
MAX 1/3
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").

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.
DRIVE WHEELS Check front drive wheels each time before
you mow to be sure they move freely. The wheels not turning freely means
trash, grass cuttings, etc. are in the drive wheel area and must be cleaned to free
drive wheels.
If necessary to clean the drive wheels, be
sure to clean both front wheels.
1. Remove hubcaps, Iocknuts & washers.
2. Remove wheels from wheel adjusters.
3. Remove any trash or grass cuttings
from inside the dust cover, pinion and/ or drive wheel gear teeth.
4. Put wheels back in place. NOTE: If after cleaning, the drive wheels
do not turn freely, contact a Sears or other qualified service center.
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 filled 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.
If lubricant is required, use only ELF
Multis EP00. Do not substitute.
BLADE CARE For best results, mower blade must be kept
sharp. Replace a bent or damaged blade. _, CAUTION: Use only a replacement
blade approved by the manufacturer of
your mower. Using a blade not approved
by the manufacturer of your mower is hazardous, could damage your mower and
void your warranty. TO REMOVE BLADE
1. Disconnect spark plug wire from spark
plug and place wire where it cannot come in contact with 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, hardened washer).
NOTE: Remove the blade adapter and
check the key inside hub of blade adapter. The key must be in good condition to work
properly. Replace adapter if damaged.
TO REPLACE BLADE
1. Position the blade adapter on the en- gine crankshaft. Be sure key in adapter and crankshaft keyway are aligned.
2. Position blade on the blade adapter aligning the two (2) holes in the blade
with the raised lugs on the adapter.
3. Be sure the trailing edge of blade (oppo- site sharp edge) is up toward engine.
4. Install the blade bolt with the lock
washer and hardened washer into
blade adapter and crankshaft.
5. 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.

TO SHARPEN BLADE
NOTE: We do not recommend sharpening 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 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.12

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
4O
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 run-
ning low on oil. Change the oil after every
25 hours of operation or at 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
NOTE: Before tipping lawn mower to drain oil, empty fuel tank by running engine until fuel tank is empty.
1. Disconnect spark plug wire from spark plug and place wire where it cannot
come in contact with plug.
2. Remove engine oil cap; lay aside on a clean surface.
3. Tip lawn mower on its side as shown and drain oil into a suitable container.
Rock lawn mower back and forth to re- move any oil trapped inside of engine.
4. Wipe off any spilled oil from lawn mower or side of engine.
5. Slowly pour oil down the oil fill spout, stopping every few ounces to check the oil level with the dipstick.
6. Stop adding oil when you reach the FULL mark on the dipstick. Wait a
minute to allow oil to settle.
7. Continue adding small amounts of oil, rechecking the dipstick until oil level
settles at FULL. DO NOT overfill, or engine will smoke heavily from the muffler on startup.
8. Always be sure to retighten oil dipstick before starting engine.
9. Reconnect spark plug wire to plug.
AIR FILTER Your engine will not run properly and may
be damaged by using a dirty air filter. Replace the air filter cartridge every 100
hours of operation or every season, which-
ever occurs first. Service air cleaner more often under dusty conditions.
TO CLEAN AIR FILTER
i
/
1. Loosen screw and tilt cover to remove.
2. Carefully remove cartridge.
3. Clean by gently tapping on a flat sur-
_i face. If very dirty, replace cartridge.
CAUTION: Petroleum solvents, such as

ENGINE 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 a Sears or other qualified
service center for repair and adjustment. CARBURETOR
Your carburetor is not adjustable. If your engine does not operate properly due to sus-
pected carburetor problems, take your lawn
mower to a Sears or other qualified service center for repair and/or adjustment.
IMPORTANT: Never tamperwith the engine governor, which is factory set for proper en- gine speed. Overspeeding the engine above
the factory high speed setting can be danger- ous. If you think the engine-governed high speed needs adjusting, contact a Sears or other qualified service center, which has
proper equipment and experience to make any necessary adjustments.
