Bleeding The Fuel System; Testing The Safety Interlock System - Toro 04383 Operator's Manual

4. Insert the key into the switch and rotate it to On. Hold it
in the On position until the glow plug indicator light
goes off (approximately 6 seconds).
5. Immediately turn the ignition key to the Start position.
Release the key when the engine starts and allow it to
move to the On position. Move the throttle control to
Slow.
Important To prevent overheating of the starter motor,
do not engage the starter longer than 10 seconds. After 10
seconds of continuous cranking, wait 60 seconds before
engaging the starter motor again.
6. When the engine is started for the first time, or after an
overhaul of the engine, operate the machine in forward
and reverse for one to two minutes. Turn the steering
wheel to the left and right to check the steering
response. Then shut the engine off (see Stopping in
Starting and Stopping the Engine, page 27) and wait for
all moving parts to stop. Check for oil leaks, loose parts
and any other noticeable malfunctions.
Stopping
1. Move the throttle control to Slow, disengage the
raise/lower mow control, and move the functional
control to neutral.
2. Rotate the starter key to Off to shut the engine off.
Remove the key from the switch to prevent accidental
starting.
3. Close the fuel shut-off valves before storing the
machine.

Testing the Safety Interlock
System
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.
Replace switches every two years regardless of
whether they are operating properly or not.
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
