SECTION 4 - MACHINE OPERATION
4-6 – JLG Lift – 3121216
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 fuel and
senses when fuel level is getting low. The JLG
Control System automatically 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 ¼
tank indicator will flash once a second and
there will be approximately 5 minutes of
engine run time left. If the system is in this con-
dition and automatically shuts down the engine, or the engine is
manually shut down before the 5 minute run time is complete,
the ¼ tank indicator will flash 10 times a second and the engine
will react according to machine setup. Setup options are as fol-
lows:
• 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 minutes 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 - The engine will shut down. No restarts will
be permitted until fuel is added to the tank.
