HOWTOUSEYOURMOWER

TO STOP ENGINE

Release blade control handle to stop engine. Discon- nect the spark plug wire and move it away from the

spark plug to prevent accidental startingwhile equip- ment isunattended.

ENGINE SPEED CONTROL

The engine speed is controlledby a lever (red knob) located on the leftside of the engine.The "HI" position is for starting engine, normal cuttingand 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 to stop 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 stopautomatically

when the controlhandle isreleased.

DRIVE CLUTCH CONTROL LEVER

To engage the wheel drive, squeeze the drive clutch

control lever against the handle. Releasing the drive

clutch control lever stops the wheels from driving.

Release the drive clutch control lever to slow down

when negotiatingan obstacle, making a turn or stop- ping.

ADJUST cu'n'ING HEIGHT The height adjuster leversfor the wheels are located

on the left side of the deck. See figure 6. The levers may be placed in one of nine cuttingheightpositions.

Bothleversshouldalways be set to the same position.

• Raise wheels for low Cut and lower wheels for high

cut.

• To change cutting height, move adjuster levers towardwheels. Movewheels upor downto suityour

(The heightadjustersmay seem hardto move when new.They will operateeasier aftersomeuse.)

BEFORESTARTINGENGINE

OIL A 27 ounce bottle of SAE 30 oil is includedwith your

newlawn mower.

Only use high quality detergent oil rated with API ser- vice classification SF, SG or SH. Select the oil's vis-

cosity grade according to your expected operating temperature.

Colder 32° Warmer

SHIFT LEVER The six speed shift lever is located below the drive

clutch control lever. Position1 is the slowest speed; position6 is the fastest. Release the drive clutchcon-

trolleverwhen changingspeeds.

IMPORTANT: Move the shift lever ONLY when the

engine is running. Shifting the speeds with the engine off can cause damage to the unit.

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 possible engine damage from running low on oil.

• Place unit so engine is in a level position.

• Remove oil fill cap and dipstick assembly. Pour oii

slowlyuntil oillevel is to the FULL markon dipstick. Crankcase capacity is approximately 27 ounces.

DO NOT OVERFILL.

NOTE: Crankcase oilshouldbe changedafter first two (2) hours of operation and everytwenty-five (25) hours

thereafter.Refer to ENGINE LUBRICATION section.

• Replace oil fill cap and dipstick. Tighten cap securely.

NOTE: The drive cable has been adjusted at the fac- tory withthe unitin sixthspeed. If the drive slipswhen

mower is operated in first speed, tighten the cable by moving the adjustment wheel away from the operator

slightly. ALWAYS MAKE CERTAIN THE MOWER

DOES NOT DRIVE WITH THE DRIVE CLUTCH CON- TROL LEVER RELEASED. Refer to "Drive Clutch Adjustment" for further information.

Connect spark plug wire to spark plug.Make cer-

tain the metal cap on the end of the sparkplugwire

(inside the rubber boot) is fastened securely over

the metal tipon the spark plug.

GAS

• Fill gastank with about 1-1/2 quarts of clean, fresh,

lead-free grade automotive gasoline. Low-lead or regular gasoline is an acceptable substitute. DO

NOT use Ethylor highoctane gasoline. Be certain containeris clean andfree from rustor foreign parti-

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.

See "STORAGE" Section for additional informa-

tion.

Never use engine or carburetor cleaner products

in the fuel tank or permanent damage may occur.

Pressprimer button as follows (cold starts only).

For each initial start, push primer button three t_mes prior to starter operation. See figure 7. Use sharp

pushes, wait between each push. Repeat the above

for each starter operation as necessary. Do not use

primer for warm engine restarts.

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 clumps of 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.

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 clutch control (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.

SIX SPEEDSHIFTADJUSTMENT

Periodic adjustment may be required due to normal wear. Adjustment is needed ifthe shift lever cannot be moved to all six positions.

• Loosen the nut which secures the adjustable cable

bracket, located on the left side of the engine. See

figure 13.

Place the shift lever in high speed (6) position. Move the bracket to make certain it is loose. Then slide it towards the rear of the unit as far as it willgo,

so that the pulley halves (beneath the deck) are against each other. Make certain the belt does not

interfere.
