This machine can be operated under normal conditions in temperatures of -20°C to 48°C
(0°F to 118°F). Consult JLG for operation outside this range or under abnormal conditions.
1. Make sure all controls are in “Neutral” and all electrical components (lights, heater,
etc.) are turned off. Apply park brake.
2. Turn ignition switch to position II and wait for engine preheat indicator on
instrument panel to go out. If active, enter anti theft code.
3. 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 for a few minutes before trying again.
4. After engine starts, observe indicators. If indicators remain on for more than five
seconds, stop engine and determine cause before restarting engine.
5. Warm up engine at approximately 1/2 throttle.
Note: Engine will not start unless transmission is in neutral and park brake is applied.

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.
