Aiming The Headlights; Starting And Stopping The Engine; Checking The Interlock Switches; Pushing Or Towing The Machine - Toro 31598 Operator's Manual

Aiming the Headlights

1. Loosen the mounting nuts and position each headlight
so that it points straight ahead. Tighten the mounting
nut just enough to hold the headlight in position.
2. Place a flat piece of sheet metal over the face of the
headlight.
3. Mount a magnetic protractor onto the plate. While
holding the assembly in place, carefully tilt the headlight
downward 3 degrees, then tighten the nut.
4. Repeat the procedure on the other headlight.
Starting and Stopping the
Engine
1. Ensure that the parking brake is set. Remove your foot
from the traction pedal and ensure that it is in neutral.
2. Set the throttle switch to the low-idle position.
3. Turn the ignition key to the Run position. The air intake
heater icon on the info center will show/disappear.
4. When the glow indicator dims, turn the ignition key
to the Start position. Release the key immediately
when the engine starts and allow it to return to the
Run position. Allow engine to warm up at low speed
(without load) for 3 to 5 minutes, then actuate the
throttle switches to attain the desired engine speed.
Important: Do not run the starter motor more
than 30 seconds at a time or premature starter
failure may result. If the engine fails to start
after 30 seconds, turn the key to the Off position,
recheck the controls and procedures, wait 2
minutes, and repeat the starting procedure.
When the temperature is below -75°C (20°F), let the
machine warm up for a minimum of 10 minutes.
5. To stop the engine, set the throttle switch to low
idle, move the PTO switch 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
CAUTION
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, the traction pedal is in neutral and the
parking brake engaged.
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 traction drive should not function. If the
traction drive still functions 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.
Important: Do not push or tow the machine faster than
3-4.8 km/h (2-3 MPH) because internal transmission
damage may occur. The bypass valves must be open
whenever the machine is pushed or towed.
1. Raise the hood and locate the bypass valves on the
pump (Figure 36).
