Cold Weather Starting Aids
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.
WARNING
ENGINE EXPLOSION. If your telehandler is equipped with a cold start aid, do
not 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.
