Shutdown Procedure
IF AN ENGINE MALFUNCTION CAUSES AN UNSCHEDULED SHUTDOWN, DETERMINE
THE CAUSE AND CORRECT IT BEFORE RESTARTING THE ENGINE.
1. Remove all load and allow engine to operate at low speed
for 3-5 minutes; this allows further reduction of internal
engine temperature.
2. Push Power/Emergency Stop switch in.
3. Turn Platform/Ground Select switch to Off.
Refer to Engine Manufacturer’s manual for detailed
information.
Fuel Reserve / Shut-Off System
NOTE: Reference the Service and Maintenance Manual along with a
qualified JLG Mechanic to verify your machine setup.
The Fuel Shutoff System monitors the fuel in the tank and senses
when the fuel level is getting low. The JLG Control System auto-
matically shuts the engine down before the fuel tank is emptied
unless the machine is set up for Engine Restart.
If fuel level reaches the Empty range, the Low Fuel
light will begin to flash once a second and there will
be approximately 60 minutes of engine run time
left. If the system is in this condition and automati-
cally shuts down the engine or if the operator man-
ually shuts down the engine before the 60 minute run time is
complete, the Low Fuel light will flash 10 times a second and the
engine will react according to machine setup. Setup options are
as follows:
• Engine One Restart - When the engine shuts down, the
operator will be permitted to cycle power and restart the
engine once with approximately 2 minutes of run time.
After the 2 minute run time is complete or if the engine is
shut down by the operator prior to the completion of the 2
minute run time, it cannot be restarted until fuel is added
to the tank.
