Typical Power Tower
The power tower can be hinged forward for clearance purposes.
Normally one of the switches at the helm area is designated as arch
or tower. It connects to a lift motor and a set of hydraulic rams that
raise or lower the wakesport tower through the switch.
Always keep body parts away from the hinge mechanisms
while raising and lowering the Power Tower. Body parts may
become entangled within the hinge mechanisms, which could
result in death or serious injury.
Make sure the operator and all aboard read and understand the above warning.
