SECTION 4 - MACHINE OPERATION
4-4 – JLG Lift – 3121289
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 get-
ting low. The JLG Control System automati-
cally 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 min-
utes of engine run time left. If the system is in this condition and
automatically shuts down the engine or if the operator manually
shuts down the engine before the 60 minute run time is com-
plete, 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.
• Engine Restart - When the engine shuts down, the opera-
tor will be permitted to cycle power and restart the engine
for approximately 2 minutes of run time. After the 2 min-
utes of run time is complete, the operator may cycle power
and restart the engine for an additional 2 minutes of run
time. The operator can repeat this process until there is no
more fuel available.
• Engine Stop - When the engine shuts down, no restarts
will be permitted until fuel is added to the tank.
