Checking The Interlock Switches; Pushing Or Towing The Machine - Toro 30410 Operator's Manual

start after 15 seconds, turn the key to the Off
position, recheck the controls and procedures,
wait 15 additional seconds, and repeat the
starting procedure.
When the temperature is less than 20°F (-75C),
preheat glow plugs twice prior to initial cranking
attempt. The starter motor can be run for 30
seconds on then 60 seconds off for 2 attempts.
5. When the engine is started for the first time, or after
an overhaul of the engine, transmission, or axle,
operate the machine in forward and reverse, off
the ground, for a minimum of two minutes. Also
operate the lift lever and PTO lever to ensure proper
operation of all parts. Turn the steering wheel to
the left and right to check steering response. Then
shut the engine off and check for oil leaks, loose
parts, and any other noticeable difficulties.
Shut the engine off and wait for all moving
parts to stop before checking for oil leaks, loose
parts, and other malfunctions.
6. To stop the engine, move the throttle control
backward to the Slow position, move the PTO lever
to the Off position, set the parking brake, and rotate
the ignition key to Off. Remove the key from the
switch to prevent accidental starting.
Important: Allow engine to idle for 5 minutes
before shutting it off after a full load operation.
Failure to do so may lead to turbo-charger trouble.
Checking the Interlock
Switches
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.
The machine has interlock switches in the electrical
system. These switches are designed to stop the engine
when operator gets off of the seat when the traction
pedal is depressed. However, the operator may get off
of the seat while the engine is running and the traction
pedal is in neutral. Although the engine will continue
to run if the PTO lever is disengaged and the traction
pedal is released, it is strongly recommended that the
engine be stopped before rising from the seat.
To check the operation of the interlock switches,
perform the following procedure:
1. Drive the machine slowly to a large, relatively open
area. Lower the cutting unit, stop the engine, and
apply the parking brake.
2. Sit on the seat and depress the traction pedal. Try
to start the engine. The engine should not crank.
If the engine cranks, there is a malfunction in the
interlock system that should be corrected before
beginning operation.
3. Sit on the seat and start the engine. Rise from the
seat and move the PTO lever to On. The PTO
should not engage. If the PTO engages, there is a
malfunction in the interlock system that should be
corrected before beginning operation.
4. Sit on the seat, engage the parking brake and start
the engine. Move the traction pedal out of the
neutral position. The engine should kill. If the
engine does not kill, there is a malfunction in the
interlock system that should be corrected before
beginning operation.
Pushing or Towing the
Machine
In an emergency, the machine can be moved forward by
actuating the bypass valve in the variable displacement
hydraulic pump and pushing or towing the machine.
Do not push or tow the machine for more than 1/4
mile (0.4 km).
Important: Do not push or tow the machine
faster than 2-3 MPH (3-4.8 km/h) because internal
transmission damage may occur. The bypass valve
must be open whenever the machine is pushed or
towed.
1. Raise the seat and remove the battery cover. The
bypass valve is located in front of the battery
(Figure 28).
2. Rotate the valve 1/4 turn in either direction to open
and allow oil to bypass internally. Because fluid is
bypassed, the machine can be slowly moved without
damaging the transmission. Note the position of
the valve when opening or closing.
3. Close the bypass valve before starting the engine.
However, do not exceed 5 to 8 ft-lb (7 to 11 N⋅m)
torque to close the valve.
