Operating Instructions

Lockout Lever Location
NOTE: The transmission plunger on the side of the
transmission case (activated by the LOCKOUT LE-
VER) must be completely released during operation
of the mower, otherwise operation of the transmis-
sion will be erratic.
Hourmeter
The hourmeter, which is located on the left front of
the body, displays operating time accumulated
while the ignition switch is in the ON position.
The hourmeter provides maintenance reminders
after certain hours of operation. The hourmeter
screen will start flashing 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 reflect the actual time that the
reminder will flash (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.
Hourmeter
Oil Pressure Warning Horn
The oil pressure warning horn indicates that engine
oil pressure is below the safe operating range [below
3 to 5 PSI (21 to 34 kPa)]. This horn will come on when
the ignition is turned ON, but should go off after the en-
gine is started. If the horn fails to come on when the
ignition switch is turned ON, it could indicate a faulty
horn. If the horn comes on during engine operation,
stop the engine immediately and correct the source
of the problem before further engine operation.
IMPORTANT: Continued operation of the engine
with oil pressure warning horn sounding MAY cause
severe engine damage (if a low oil pressure condi-
tion exists).
Circuit Breaker (7 Amp)
A 7-amp, manual-reset circuit breaker is located be-
low the ignition switch. The button pops up if the cir-
cuit breaker trips. This circuit breaker protects the
circuits to the safety switch relays, time delay mod-
ule, and GHS.
Light Switch (For Optional Lights)
Operates headlights (when installed).
