NOTE: The transmission plunger on the side of the transmission case (activated by the LOCKOUT LEVER ) must be completely released during operation of the mower, otherwise operation of the transmission 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 3to5PSI(21 to34kPa)]. Thishornwill come on when the ignition is turned ON, but should go off after the engine 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 condition exists).

Circuit Breaker (7 Amp)

A7-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).
