machine and out of the area of operation. Move the shift
selector to Neutral, make sure the mow pedal is disen-
gaged, set the throttle control at half speed and engage the
parking brake. Hold the steering wheel, brace your feet on
the foot deck and brake pedal, and move the shift selector
to the #1 position. Carefully rise off the seat; the engine
should stop. If the engine stops, the interlock system is
operating correctly. Repeat this check with the shift selec-
tor in the #2 position. If the engine does not stop, stop the
engine and find the problem before operating the machine.
If you need assistance, contact your local TORO dealer.
CHECK THE LEAK DETECTOR'S
OPERATION
The TURF GUARDIAN™ leak detector detects hydraulic oil
system leaks. If the oil level in the main hydraulic reservoir is
lowered by 4 to 6 ounces, the float switch in the tank will close.
After a 1-second delay, the alarm will sound. Expansion of oil,
due to normal heating during machine operation, will cause oil
to transfer into the auxiliary oil reservoir. The oil is allowed to
return to the main tank when the ignition switch is turned off.
To check system operation
1. With the ignition switch in the ON position, move the leak
detector switch rearward and hold. After the one-second
time delay elapses, the alarm should sound.
2. Release leak detector switch.
To check leak detector system operation
1. Move the ignition switch to ON. DO NOT START THE
ENGINE.
2. Remove the hydraulic tank cap and strainer from the neck
of the tank.
3. Insert a clean rod or screw driver into the tank neck and
gently push down on the switch float (Fig. 12). The alarm
should sound after a one-second delay.
4. Release the float; the alarm should stop.
5. Install the strainer screen and the hydraulic tank cap.
Move the ignition switch to OFF.
