Checking The Safety Interlock System; Checking The Leak Detector - Toro 04357 Operator's Manual

Checking the Safety Interlock
System
If the 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.
The purpose of the safety interlock system is to prevent
operation of the machine where there is possible injury
to the operator or the machine.
The safety interlock system prevents the engine from
starting unless:
• The traction pedal is in neutral.
• The functional control lever is in neutral.
The safety interlock system prevents the machine from
moving unless:
• The parking brake is off.
• The operator is seated.
• The functional control lever is in Mow or Transport.
The safety interlock system prevents the reels from
operating unless the functional control lever is in the
Mow position.
Perform the following system checks daily to be sure
the interlock system is operating correctly:
1. Sit on the seat, move the traction pedal to Neutral,
move the functional control lever to Neutral, and
engage the parking brake. Try to depress the
traction pedal. The pedal should not depress,
which means that the interlock system is operating
correctly. Correct the problem if it is not operating
properly.
2. Sit on the seat, move the traction pedal to Neutral,
move the functional control lever to Neutral, and
engage the parking brake. Move the functional
control lever to mow or transport and try to start the
engine. The engine should not crank, which means
that the interlock system is operating correctly.
Correct the problem if it is not operating properly.
3. Sit on the seat, move the traction pedal to Neutral,
move the functional control lever to Neutral,
and engage the parking brake. Start the engine
and move the functional control lever to mow or
transport. The engine should kill, which means that
the interlock system is operating correctly. Correct
the problem if it is not operating properly.
4. Sit on the seat, move the traction pedal to Neutral,
move the functional control lever to Neutral, and
engage the parking brake. Start the engine. Release
the parking brake, move the functional control
lever to mow, and rise from the seat. The engine
should kill, which means that the interlock system
is operating correctly. Correct the problem if it is
not operating properly.
5. Sit on the seat, move the traction pedal to Neutral,
move the functional control lever to Neutral, and
engage the parking brake. Start the engine. Move
the raise/lower mow control forward to lower the
cutting units. The cutting units should not start
rotating. If they do, the interlock system is not
operating correctly. Correct the problem.

Checking the Leak Detector

The leak detector system is designed to assist in early
detection of hydraulic oil system leaks. If the oil level
in the main hydraulic reservoir, is lowered by 4 to 6
ounces (118-177 ml), the float switch in the tank will
close. After a one second delay, the alarm will sound,
alerting the operator (Figure 29). Expansion of oil, due
to normal heating during machine operation, will cause
the 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.
