Ether Cold Start Button
The ether cold start button (4) is used to inject ether,
a highly combustible substance, into the engine
intake manifold. Ether will ignite in the engine at
temperatures far below those needed to ignite diesel
fuel.
Use the ether to assist the engine starting in
temperatures at or below 0° C (32° F).
Note: See cold-weather starting on page 3-51 for
detailed operation.
