Some AVSpare machines may be equipped with auxiliary starting receptacles. All other machines can be equipped with a receptacle from parts service. A permanent receptacle is always available for jump starting.

There are two cable assemblies that can be used to jump start the stalled machine. You can jump start the stalled machine from another machine that is equipped with an auxiliary starting receptacle or with an auxiliary power pack. Your AVSpare dealer can provide the correct cable lengths for your application.
