BEFORE STARTING ENGINE ADD OIL Your lawnmower is shipped withoutoil in
the engine. Engine holds 20 oz. of oil.
For type and grade of oil to use, see =ENGINE" in Maintenance section of this
manual.
1. Be sure lawnmower is level and area around oilfill is clean.
2. Remove engine oil cap and fill to the full line on the dipstick. Pour oil slowly. Do not over fill.
NOTE: Allow oil to settle down into engine for accurate reading. To read proper level,
tighten engine oil cap, then remove it to read the dipstick,
3. Reinstall engine oil cap and tighten.
Check oil level before each use. Add
oil it needed. Fillto 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.
ADD GASOLINE
Fill fuel tank. Use fresh, clean, regular
unleaded gasoline with a minimum of
87 octane. Do not mix oil with gaso-
line. Purchase fuel in quantities that can be used within 30 days to assure
fuel freshness.
A,WARNING: Experience indicatesthat 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 untilthe fuel lines and carburetor are empty. Use fresh fuel
next season. See Storage Instructionsfor additional information. Never use engine or carburetor cleaner productsin the fuel
tank or permanent damage may occur. _, CAUTION: Fill to bottom of gas tank
filler neck. Do not overfill. Wipe off any spilled oil or fuel, Do not store, spillor use gasoline near an open flame.

TO START ENGINE NOTE: Due to protective coatingson the
engine, a small amount of smoke may be present during the inkial use of the product and should be considered normal.
I. To start a cold engine, push pdmer
three (3) times before trying to start.
Usa e firm push. This step is net
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.
8
TO STOP ENGINE
To stop engine, release operator presence control bar.
NOTE: In ccoler weather it may be necessary to repeat pdmingsteps. In
warmer weather over pdming may cause flooding and engine willnot start. If you
do flood engine, wait a few minutes before attempting to startand 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 push ng
effortand to keep from overloading the engine and leaving clumps of grass clippings. It may also be necessary to
reduce groundspeed 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 roar discharge lawn
mower in moist, heavy grass, clumps of cutgrass may not enter the grass catcher. Reduce ground speed (pushing speed) and/or runthe lawn
mower over the area a second time.
If a trail of clippingsis left on the dght side of e rear discharge mower, mow in
a clockwise direction with a small overlap to collectthe clippingson the
next pass.
Pores in cloth grass catchers can
become filled with dirt and dust with use and catchers will collect lessgrass.
To prevent this, regularly hose catcher
off with water end let dry before using.
Keep top of engine around starter clear and clean of grass clippingsand chaff. This will help engine air flow and extend engine life.
MULCHING MOWINGTIPS IMPORTANT: For bestperformance,
keep mower housing free of built-up grass and trash. See =CLEANING" in the
Maintenance section of this manuel.
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 intothe
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 recuttingaction of the blades.
Avoid cuttingyour lawn when it is wet.
Wet grass tends to form clumps and
interferes with the mulching action. The best time to mow your lawn isthe
early aftemcon. At this time the grass has dried and the newly cut area will
notbe exposed to the direct sun.
For best results, adjust the lawn mower cutting height so that the lawn mower
cutsoff only the top one-third of the grass blades. If the lawn Is overgrown it will be necessary to raise the height ef cut to reduce pushing effort and to keep from overloading the engine and
leaving clumps of mulched grass. For extremely heavy mulching, reduce your width of cut by overlapping previously
cut path and mow slowly.
Certain types of grass and grass
conditionsmay require that an area be
mulched a second time to completely
hide the clippings. When doing a
second cut, mow across or perpendicu-
lar to the firstcut path.
Change your cutting pattern from week
to week. Mow northto south one week
then change to east to west the next
week. This will help prevent matting
and graining of the lawn.

TO SHARPEN BLADE
NOTE: We do not recommend sharpen- ing blade - but ff 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 grindingwheel. Do not attempt
to sharpen while on the mower.
To check blade balance, drive a nail
into a beam or wall. Leave about one inchof 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 drywhen used.
Check your grass catcher often for
damage or detedoration. Through normal use it will wear. If catcher
needs replacing, replace only with a manufacturer approved replacement
catcher. Give the lawn mower model number when ordedng.
DRIVE WHEELS Check front drive wheels each time beforeyou mow to be sure they move
freely.
The wheels notturning freely means trash, grass cuttings, etc. are inthe ddve
wheel area and must be cleaned to free drive wheels,
If necessary to clean the ddve wheels,
check beth front wheels.
1. Remove hubcaps, hairpin cotters and 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 turnfreely, contact a Sears or other qualified service center.
GEAR CASE
To keep your drive system working prepedy, the gear case and area around the drive should be kept clean and free of trash build-up. Clean under
the ddve cover twice a season.
The gear case is filled with lubdcant to the proper level at the factory. The only
time the lubdcant needs attentionis if service has been performed on the gear case.
If lubdcant is required, use only Texaco Starplex Premium 1 Grease, Part No.
750369. Do not substitute.
ENGINE LUBRICATION
Use only high quality detergent oil rated with API service classification SF-SJ.
Select the oil's SAE viscositygrade according to yourexpected operating
temperature,
NOTE: Although multi-viscosifyoils (5W30, 10W30 etc.) improve startingin cold weather, these multi-viscosityoils 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
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
startingthe engine and after each five (5) hours of continuous use. Tighten oil plug securely each time you check the oil
level.
