JLG approved starting aids employ ether. If your telehandler is equipped with an
ether starting aid, the following applies:
• Injection of ether is triggered by temperature sensor located on engine.
• At start-up, temperature sensor on engine will detect if ether is needed. Follow
normal start-up procedure.
• Ether will be automatically injected if needed, to keep engine running.
• A second battery is added for additional cold-cranking capacity.

Perkins and Cummins engines are equipped with preheat for cold weather starting.
Refer to “Starting the Engine” on page 4-1 for cold weather starting procedure.

spray additional ether into air cleaner. If machine is not equipped with cold start
aid, follow instructions listed in the engine manual supplied with the telehandler.
