ment isunattended.
ENGINE SPEED CONTROL
The engine speed is controlledby alever (red knob)
located on the leftside of the engine.The "HI" position
is for starting engine, normal cutting and best perfor-
mance. The "LOW" position is for light cutting,trim-
mingand fuel economy.
BLADE CONTROL HANDLE
Your mower has a control handle which requires the
operator to be behindthe handle to start and run the
mower.When the operator releases the control han-
dle, the engine will stop and an internal brake helps
the blade tostop quickly.
When the operator leaves the operating position to
change the cutting height, pick up sticks or other
objects in the way, the engine will stop automatically
when the controlhandle isreleased.
DRIVE CLUTCH CONTROL LEVER

vice classification SF, SG or SH. Select the oil's vis-
cosity grade according to your expected operating
temperature.
Colder 32° Warmer
NOTE: Although multi-viscosity oil (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 oil level more fre-
quently to avoid possibleengine damage from running
low on oil.

cles. Never use gasoline that may be stale from
long periodsof storage inthe container.
WARNING: Experience indicates that alcohol
blended fuels (called gasohol or using ethanol or
methanol) can attract moisture which leads to sep-
aration 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
for 30 days or longer. Use fresh fuel next season.

MULCHINGORMOWINGTIPS
• For best results in normal and heavy mowing,
always run engine in "HI" speed position. "LOW"
speed is only for light cutting, trimming and fuel
economy.
• The grass condition at the time of mowing deter-
mines the proper mower cutting height setting for
best lawn appearance. For a healthy lawn, always
cut one-third or less of the total length of the grass
at any one cutting.
• 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 clumpsof grass clippings.
• For extremely heavy cutting, use a slow ground
speed, and reduce the width of cut.
• Under heavy conditions cross cut for additional
mulching of surface debris.
GENERALRECOMMENDATIONS
• In order to maintain the warranty on your mower,
the customer is expected to perform the mainte-
nance as outlinedbelow.
• Once a year you shouldreplace the spark plug,air
filter, and check blade for wear. A new spark plug
and air filter assures proper air-fuel mixture and
helpsyourengine runbetter and lastlonger.

Use onlya Sears authorizedreplacament blade to get
thebest cuttingresults.
NOTE: We do not recommend sharpeningthe blade--
but ifyou do, be sure blade isbalanced.
TO SHARPEN BLADE
•The blade can be sharpened with a file or on a
grindingwheel. Do not attemptto sharpen while on
the mower,
11

• Care should be taken to keep the blade balanced.
An unbalanced blade will cause excessive vibration
when running and eventual damage to mower and
engine.
• 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, blade is not balanced. Sharpen the
heavy end until the blade is balanced.

DRIVECLUTCHADJUSTMENT
The correct drive clutch adjustment varies with the
speed of the mower. The drive clutch adjustment may
be checked as follows. Without starting the engine,
engage the ddve clutchcontrol(squeeze control lever
against the handle) and pull the mower backward. The
wheels should lock. Then release the drive clutch con-
trol and pull the mower backward. It should move
freely (or with only a small amount of resistance).
If the wheels lock up when pulled backward with the
drive clutch control released (engine off), or if mower
moves forward with the drive clutch control released
(engine running), turn the adjustment wheel, located
beneath the drive clutch control housing, toward the
operator to loosen the cable. See figure 12. Recheck
the adjustment as instructed above.
If the mower does not drive in low speed, tighten the
cable by turning the adjustment wheel away from the
operator. Recheck the adjustment.
Periodic adjustment may also be necessary due to
normal stretch and wear on the belt. Adjustmentmay
be needed if the wheels seem to hesitate, but the
engine maintains the same speed. To tighten the
cable, move the adjustment wheel toward the right.
Alwaysbe certaintorecheckthe adjustment.
