Remove a wheel assembly and reinstall it in a

different position in order to achieve a higher or

lower position. Refer to the Assembly section also.

Repeat this procedure for all wheels, being certain

to mount them all in the same position at each

corner. Failing to do this will produce an uneven

cut.

Resettingthe CircuitBreaker

The mower is equipped with a circuit breaker, located

on the motor/blade control assembly as shown in

Figure 9. This circuit breaker may trip when too much

strain is placed on the mower. The circuit breaker may

have been tripped if the mower will not run.

If this occurs, unplug the mower, wait

approximately five minutes, then depress the reset

button. Refer to Figure 9.

Plug the mower back in, restart the mower, but be

sure to reduce the strain on the mower (i.e., mow at

a higher cutting height, reduce cutting speed, or

take a smaller width of cut).

If the circuit breaker does not reset, or if it trips

repeatedly under normal cutting conditions, unplug

the mower from the extension cord and unplug the

extension cord from the power source. Then check

to make certain your cord is the correct length and

rating as listed in the Operating YourLawn Mower

section. If the cord is correct and is also not

damaged, take the machine to an authorized

service dealer for repair.

heavy gloves and/or wrapping cutting edges with

newspapers or other materials when performing

any blade maintenance. Be certain to disconnect

the power supply.

Removingthe Blade

Stop the motor and disconnect the power supply to

the mower. Turn the mower on its side.

Use a block of wood between the blade and the

mower deck to prevent the blade from turning when

removing the bolt.

Using a 15/16" wrench or socket, loosen the blade

bolt and remove the blade.

InstallingtheBlade

WARNING: The blade hardware is not only

used to attach the blade assembly, but is also an

insulated safety device and should never be altered

in any way. If replacement is necessary, use

original equipment parts as shown in the parts list

on page 16.

Place the cutting blade, locking plate, and blade

bolt on the motor shaft and thread the blade bolt in

finger tight. Refer to Figure 12.

NOTE: Make certain to replace the parts in the exact

order in which they were removed. When installing the

cutting blade, be sure it is installed with the curved ends

pointing towards the mower deck and not towards the

ground.

Torque the blade bolt down using a torque wrench

to assure the bolt is tightened properly. The

recommended torque for the blade bolt is 450-600

in. Ibs. To insure safe operation of your unit, all nuts

and bolts must be checked periodically for correct

tightness.
