SECTION7: MAKINGADJUSTMENTS
CuttingHeightAdjustment
Cutting Height
ustment Lever
Figure 12
A height adjustment lever at each wheel provides
cutting height adjustment. Each adjuster has nine
height positions. Height of cut will be changed when the
lever is moved from one position to another.
Depress the lever towards wheel and move wheel
and lever assembly to desired position.
To raise the height, push the lever towards the front
of the mower on both front wheels, and push the
lever toward the back of the mower on the rear
wheels.
Refer to Figure 12. All wheels must be placed in the
same relative position. For rough or uneven lawns,
move the wheels to a position which will give a higher
cutting height.
HandleHeightAdjustment
The upper handle may be adjusted to three
different height positions. To adjust the handle at
the desired position, align one of the three marks
on the top of the lower handle insulators with the
mark on the upper handle insulators. Refer to
Figure 4.
Tighten the hand knobs on each side of the handle.
Make sure that carriage bolts are seated properly
into the handle insulators.
ResettingtheCircuitBreaker
The mower isequipped with a circuit breaker, located
on the motor/blade control assembly as shown in
Figure 10. 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 10.
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, slow down 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.
SECTION8: MAINTENANCE
WARNING: Always stop the motor and
disconnect from the power source before cleaning,
lubricating or performing any repairs or
maintenance on the lawn mower.

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 blade and mower
deck to prevent the blade from turning when the
bolt is removed.
Using a 24mm wrench or socket, loosen the blade
bolt and remove the blade.
