Engine Starting
The mower’s safety start interlock system is also designed
to protect the operator and others from accidental injury due
to unintentional engine starting. The engine starting motor
will not engage until:
1. The park brake lever is in the engaged park brake
position.
2. The steering control levers are in the netural position.
3. The deck clutch switch is in the down (deck blades
disengaged) position.
Start the engine by following these steps. If you encounter
difficulty, contact your Hustler
®
Dealer.
1. Make sure the park brake lever is in the engaged park
brake position, the steering control levers are in the
neutral position and the deck clutch switch is
disengaged (mower blades disengaged).
Start the
engine from the operator’s position only.
2. Use the choke, if the unit is equipped with one, when
the engine is cold, or if a warm engine fails to start
within 5 seconds of cranking. Avoid flooding by
operating the engine without choking as soon as
possible.
3. Set the throttle at approximately the 1/2 open
position.
4. Insert the key in the ignition switch and rotate it
clockwise to engage the starting motor. Release the
key when the engine starts.
IMPORTANT: The engine starter should not be
operated for periods longer than 30 seconds at a time.
At least two minutes between such cranking periods to
protect the starter from overheating and burning-out.
5. As soon as the engine begins to run, check to make
certain all engine warning lights are off. If not, stop the
engine immediately and check for the cause.
6. Perform the test shown in the Safety Start Interlock
System section to make sure the safety start interlock
system operates properly.
7. Allow the engine to idle two minutes before advancing
the throttle and/or engaging the deck clutch.
Stopping the Engine
Use the following procedure to shut the engine off.
1. Place the steering control levers in the neutral
position.
2. Throttle the engine back to low idle, then disengage
the deck clutch. Refer to the
Mower Deck Operation
section for more details.
3. Place the park brake lever in the engaged park brake
position.
4. Let the engine run at low idle for two minutes.
5. Rotate the ignition key counter-clockwise to the “OFF”
position. Remove the key from the switch before
leaving the mower.
