MUFFLER
Inspect and replace corroded muffl er as it
could create a fi re hazard and/or dam age.
SPARK PLUG
Replace spark plug at the beginning of
each mowing season or after every 100
hours of operation, whichever occurs
fi rst. Spark plug type and gap setting are
shown in "PROD UCT SPEC I FI CA TIONS"
in Maintenance section of this manual.
CLEANING
IMPORTANT: For best performance, keep
mower housing free of built-up grass and
trash. Clean the underside of your mower
after each use.

SERVICE AND ADJUSTMENTS

before per form ing any service or ad just -
ments:

LAWN MOWER
TO ADJUST CUTTING HEIGHT
See "TO ADJUST CUTTING HEIGHT" in
the Operation sec tion of this manual.
REAR DEFLECTOR
The rear defl ector, attached between the
rear wheels of your mower, is provided to
minimize the possibility that objects will
be thrown out of the rear of the mower
into the operator mowing position. If the
defl ector becomes dam aged, it should be
replaced.
TO ADJUST HANDLE
The handle on your lawn mower has three
(3) height positions - adjust to height that
suits you.
NOTE: The upper handle has an "anti-
fold" bracket located on the left side of the
handle. This bracket prevents the upper
handle from folding forward, which helps
protect control cable(s) from damage.
• Squeeze the bottom ends of lower
handle towards each other until the pin
in handle can be inserted into one of the
three height adjustment holes.
CAUTION: Disconnect spark plug wire
from spark plug and place wire where it
cannot come in contact with the spark plug.
• Clean the underside of your lawn mower
by scraping to remove build-up of grass
and trash.
• Clean engine often to keep trash from
accumulating. A clogged engine runs
hotter and shortens engine life.
• Keep fi nished surfaces and wheels free
of all gasoline, oil, etc.
• We do not recommend using a garden
hose to clean lawn mower unless the
electrical system, muffl er, air fi lter and
carburetor are covered to keep water
out. Water in engine can result in short-
ened engine life.

ENGINE SPEED
Your engine speed has been factory set.

repair and adjustment.

CARBURETOR
Your carburetor has a non-adjustable fi xed
main jet for mixture control. If your engine
does not operate properly due to sus pect ed
carburetor problems, take your lawn mower
to a Sears or other qualifi ed service center
for repair and/or ad just ment.
Immediately prepare your lawn mower for
storage at the end of the season or if the
unit will not be used for 30 days or more.
LAWN MOWER
When lawn mower is to be stored for a
period of time, clean it thor oughly, remove
all dirt, grease, leaves, etc. Store in a
clean, dry area.
1. Clean entire lawn mower (See
"CLEANING" in the Maintenance sec-
tion of this manual).
2. Lubricate as shown in the Main te nance
section of this manual.
3. Be sure that all nuts, bolts, screws, and
pins are securely fas tened. Inspect
moving parts for damage, breakage
and wear. Replace if necessary.
4. Touch up all rusted or chipped paint
surfaces; sand lightly before painting.
HANDLE
You can fold your lawn mower handle for
Handle
storage.
bracket
NOTE: The upper handle has an "anti-
fold" bracket located on the left side of the
handle. This bracket prevents the upper
handle from folding forward, which helps
protect control cable(s) from damage.
1. Loosen the two (2) handle knobs on
sides of the upper handle and allow
handle to fold down to the rear.
2. Squeeze the bottom ends of lower
handle toward each other until pins
in handle clear the brackets and pivot
entire handle assembly forward and
allow it to rest on mower.
• When setting up your handle from the
storage position, the lower handle will
require manually locking into the mow-
ing position.
IMPORTANT: When folding the handle for
storage or trans por ta tion, be sure to fold
the handle as shown or you may damage
the control cables.
IMPORTANT: Never tamper with the engine
governor, which is factory set for proper en-
gine speed. Over speed ing 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 qualifi ed service center, which has
proper equip ment and ex pe ri ence to make
any nec es sary adjustments.

FUEL SYS TEM
IMPORTANT: It is important to prevent
gum deposits from forming in essential
fuel system parts such as carburetor, fuel
fi lter, fuel hose or tank during storage.
Also, 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.
