FUEL RESERVE / SHUT-OFF SYSTEM
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 Empty range, the Low Fuel Indicator or remaining level of the
Fuel Gauge 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 automatically shuts
down the engine or if the operator manually shuts down the engine before the 60
minute run time is complete, the Low Fuel Indicator or remaining level of the Fuel
Gauge 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 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 - When the engine shuts down, no restarts will be permitted until fuel is
added to the tank.

DIESEL PARTICULATE FILTER (IF EQUIPPED)
Diesel Particulate Filter (DPF) is an emissions control system used in diesel engines and
requires operator interaction to ensure proper operation of the system.
For peak operation, the DPF system must be cleaned using one of two methods,
Standstill Cleaning and Maintenance Standstill Cleaning. Standstill Cleaning is any
cleaning requested by the engine outside of the regular maintenance window (for
example, if the system detects excessive soot in the DPF canister). Maintenance
Standstill Cleaning is cleaning requested by the engine on the regular maintenance
interval.
