Toro GT Classic 73450 - Indicator Lights; Checking the Safety Interlock System

17
Hour Meter
The hour meter records the number of hours the engine
has operated (Fig. 12). It is turned on when the ignition
switch is in the run position. Use these times for
scheduling regular maintenance.
Voltmeter
The voltmeter shows the electrical system battery voltage
(Fig. 12). When you turn the ignition key to run, the
gauge should read 12 volts or slightly higher. After the
engine starts, the gauge should read between 12 and 15
volts. If the gauge reads less than 12 volts, the battery is
discharging. If the gauge reads 15 volts for long periods of
time, check the battery water more often.

Indicator Lights
The indicator lights (Fig. 13) illuminate when certain
controls are activated and when certain conditions occur
that need immediate attention. Under normal operating
conditions the lights should be off.

Operating–in–Reverse
The reverse mowing selected light (Fig. 13) will
illuminate whenever the Keychoice switch is used to
deactivate the operating–in–reverse interlock. It is a
reminder that the interlock system is deactivated. The
light goes out whenever the power take off (PTO) is
disengaged or the engine is shut off.
PTO (Power Take Off) Clutch
When the PTO clutch light is on it indicates the PTO
clutch must be disengaged before the engine will start
(Fig. 9).
Engine Oil
When the oil light blinks it indicates the engine oil
pressure is low (Fig. 9). After the engine starts the light
should go out. When the engine is running if the oil
pressure drops below a safe operating level the light
blinks. Stop engine immediately and correct the cause
of low oil pressure.
Checking the Safety Interlock
System
If safety interlock switches are disconnected or
damaged the machine could operate unexpectedly
causing personal injury.
• Do not tamper with the interlock switches.
• Check the operation of the interlock switches
daily and replace any damaged switches before
operating the machine.
Caution
Understanding the Safety Interlock
System
The safety interlock system is designed to prevent the
engine from starting unless:
• You are sitting on the seat.
• The gear shift lever is in neutral.
• The power take off (PTO) is disengaged.
The safety interlock system is designed to stop the engine
if:
• You rise from the seat when the power take off (PTO)
is engaged.
• You rise from the seat when the gear shift lever is not
in neutral.
