This machine can be operated in temperatures of -20°C to 40°C (0°F to 104°F).
Consult JLG for operation outside this range.
1. If equipped, turn on the battery disconnect switch located in engine
compartment.
2. Make sure all controls are in “Neutral” and all electrical components (lights,
heater, defroster, etc.) are turned off. Set parking brake and ensure emergency
stop button is pulled out.
3. Turn ignition switch to position I. Wait approximately four seconds as the control
system performs diagnostics as indicated by “DIAG” and hourglass symbols on
the display. Enter anti theft code if anti theft device is activated.
4. Turn ignition switch to the position II. If temperature is below 0°C, wait for
preheat symbol on display to disappear.
5. Turn ignition switch to position III to engage starting motor. Release key
immediately when engine starts. If engine fails to start within 20 seconds,
release key and allow starting motor to cool a few minutes before trying again.
Note: After engine starts, all controls are inoperable for four seconds while
diagnostics are run.
6. After engine starts, if engine oil pressure does not rise for more than ten
seconds, the engine oil pressure symbol will show on display screen and buzzer
will sound. Stop engine and determine cause before restarting engine.
Reference engine manual for minimum pressure at operating temperature.
7. Warm up engine at approximately 1/2 throttle.
Note: Engine will not start unless transmission control lever is in “Neutral” and park
brake is applied.

lever is in neutral and the service brake is applied before releasing park brake.
Releasing park brake in either forward or reverse could cause the machine to
move abruptly, causing an accident resulting in death or serious injury.
