The electric pump already comes with a substantial amount of electrical cord. We do not recommend using a long, thin
extension cord to operate the electric pump as you may experience significant "amp loss" and harm the motor. If you're
going to use an extension cord, the shorter and thicker the size of the cord, the better.
On the optional electric pump upgrade, the green button will raise the lift, and the red button kills power to the motor,
and the lever with black ball knob at the end will lower the lift.
