Fuel Shutoff System (Reserve) - JLG 1850SJ Operation & Safety Manual

4.7

FUEL SHUTOFF SYSTEM (RESERVE)

Note: Reference the Service and Maintenance Manual along with a qualified JLG Me-
chanic 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 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 Low Fuel 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
condition 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 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 operator 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.
Contact a qualified JLG mechanic if the machine needs restarted after no more fuel
is available.
• Engine Stop - The engine will shut down. No restarts will be permitted until fuel is
added to the tank.
