Usingunapprovedattachments,(especially"stand-

up" riding attachments) may be hazardous.

MAINTENANCE AND STORAGE

1. Disconnect the spark plug wire from the spark

plug to prevent accidental starting of the engine

when servicing, adjusting or storing the machine.

2. If the mower must be tipped to perform mainte-

nance or adjustment, remove the battery, drain

the gasoline from the fuel tank and the oil from

the crankcase.

3. To reduce potential fire hazard, keep the engine

free of excessive grease, grass, leaves and accu-

mulations of dirt.

4. Be sure the machine is in safe operating condition

by keeping nuts, bolts, and screws tight. Check

the blade mounting bolts and nuts frequently to

be sure they are tightened.

5. If the engine must be running to perform a

maintenance adjustment, keep hands, feet, cloth-

ing and other parts of the body away from the

cutter deck blades and other moving parts.

6. Do not overspeed the engine by changing gover-

nor settings. To be sure of safety and accuracy,

have an authorized dealer check maximum engine

speed with a tachometer.

7. The engine must be shut off before checking the

oil or adding oil to the crankcase.

8. Allow the engine to cool before storing the

mower in any enclosure such as a garage or

storage shed. Make sure the fuel tank is empty if

the machine is to be stored in excess of 30 days.

Do not store the mower near any open flame or

where gasoline fumes may be ignited by a spark.

charged or discharged. Keep batteries away

from any source of sparks and/or flame.

INITIAL RUN-IN PROCEDURES

(FIRST DAY OF USE OR APPROXI-

MATELY 10 HOURS)

1. Check the belts for proper tension at 2, 4 and 8

hours. Adjust as needed.

2. Check the steering control rods for neutral

adjustment. (See Adjustments, page 6)

3. Checkthetiresforproperpressure.

CasterWheels 25psi.

DriveWheels 15psi.

6. Applylubricantto allthegrease fittings.

Lubricant was applied at the factory. This is

just a precautionary check to make sure that

allthefittingshavebeenlubricated.

1. Read and understand the safety instructions

before attempting to operate this machine.

2. Before starting the engine:

* Check the oil level in the engine.

* Fill the fuel tank with clean, fresh, lead-free

gasoline.

* Open the fuel valve on the bottom of the

fuel tank.

MOWER OPERATION

-NOTE-

Use gasoline with an octane rating no less than

87.

* The transmission must be in NEUTRAL.

* The blade clutch switch must be in the OFF

position.

* The operator's presence levers must be

released.

* The neutral latches must be in the neutral

lock position.

* The key switch must be on.

3. Start the engine:

* Choke as required. If the engine is cold, pull

the choke knob out. When the engine starts,

slowly push the choke in. If the engine stalls,

repeat the above operation. When the engine

is warm, choking may not be necessary.

390S0138

PULL UP TO ENGAGE

PUSH DOWN TO DISENGAGE

-NOTE-

When PTO is engaged or (possibly) disengaged,

a squealing sound from the underside of the

machine is normal. It is caused by the electric

clutch plates meshing as the cutter blades come

up to speed. For best equipment life, engage the

clutch with the engine at 1/2 throttle, not under

full load.

To avoid serious bodily injury and damage to the

transmission, the machine must be at a full stop

before shifting between gears or shifting between

forward and reverse.

5. Shift the transmission into gear for the desired

mowing speed.

-NOTE-

Top speed is suggested only for transport!

6. While squeezing the steering brake levers with

both hands, release both neutral latches.

7. When the steering brake levers are released, the

machinewill travelstraight. Tomakearightturn,

squeezetheRHlever. Toturnleft,squeezetheLH

8. TO STOP, squeeze both levers, lock the neutral

latches, and shift the transmission into neutral.
