Ryobi 136 - Manual (Page 13)

• 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 ail wheels, being certain
to mount them all in the same position at each
corner. Failing to do this will produce an uneven
cut.
Resetting the Circuit Breaker
The mower is equipped with a circuit breaker, located
on the motor/biade 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 Your Lawn Mower
section. If the cord is correct and is also not
damaged, take the machine to an authorized
service dealer for repair.
SECTION 7: MAINTENANCE
A
WARNINGi
Always stop the motor and
disconnect from the power source before cleaning,
lubricating or performing any repairs or
maintenance on the lawn mower.
Cutting Blade Replacement
A
WARNING: Always protect hands by wearing
heavy gloves and/or wrapping cutting edges with
newspapers or other materials when performing
any blade maintenance. Be certain to disconnect
the power supply.
Removing the 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.
Installing die Blade
A 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. lbs. To insure safe operation of your unit, all nuts
and bolts must be checked periodically for correct
tightness.
