If a blower arrives and will not turn on when plugged in, the air switch may be in the wrong position. If this happens, we can have Evo sent out a air plunger to use to move the switch into the opposite position, or you can simply us a small blast of air to reposition the switch. EVO Blowers are NOT intended to get wet inside. Therefore, the ball valve below the blower should always be in the closed position before the pump is turned on and whenever the pump is running. In the same way, the blower should not be left out in the rain.
