Hourmeter
The hourmeter, which is located on the right front of
the body, displays operating time accumulated
while the PTO (blade drive) clutch is engaged.
The hourmeter provides maintenance reminders af-
ter certain hours of operation. The hourmeter screen
will start ashing the reminder one hour prior to the
recommended interval and will continue until one
hour after the recommended interval (two hours).
The hourmeter does not have a manual reset
function.

* These intervals reect the actual time that the
reminder will ash (one hour prior to and one
hour after the recommended interval).
** This reminder is only used one time.
*** In normal operating conditions, oil changes in
100-hour intervals are acceptable. Walker and
the engine manufacturers recommend engine
oil changes every 50 hours in extremely dirty or
dusty conditions or for units with less than 100
hours annual use.
NOTE: The blinking hour glass on the display
means that the meter is operating properly.

Ignition Switch
The ignition switch is located on the right front of the
body and is used to start and stop the engine. The
switch has three positions: “O” is the OFF position,
ON (RUN) is the position that the key returns to after
starting, and “S” is the START position. When start-
ing the engine, turn the key clockwise to the “S” po-
sition. Do not hold the key in the “S” position longer
than 10 seconds. If the engine does not start, return
the key to the “O” position for at least 60 seconds
before making a restart attempt. Prolonged crank-
ing can damage the starter motor and shorten bat-
tery life. Release the key when the engine starts,
and it will return to the ON (RUN) position. To stop
the engine, rotate the key counterclockwise to the
“O” position.
Circuit Breakers
A manual reset 5 amp circuit breaker is located
above the hourmeter. The button pops out if the
circuit breaker trips. This circuit breaker protects the
circuits to the safety switch relays and GHS. In ad-
dition, an auto reset 30 amp master circuit breaker
is located in the rear left hand side of the chassis,
and protects the charging system.
