eign objects. Keep all people, especially children,
away from the front of the machine and out of the area
of operation. Move the shift selector to Neutral, make
sure the mow pedal is disengaged, set the throttle con-
trol 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 posi-
tion. 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 selector 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 reser-
voir 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.
