Abstract: This invention allows a painter to use a sprayer 12 to reach objects or surfaces that would otherwise be out of reach for them. A step 10 is provided on the sprayer 12 which provides a quick and easy solution for users when prepping and cleaning a room. This feature would easily allow an average sized man to reach the ceiling in an 8 foot room and other similar heights. In this function the step 10 would allow the sprayer frame 14 to act as a step stool or step ladder.

Abstract: A system provides electrical power and compressed air includes a wheeled hand truck frame, an engine, a compressor, a generator, and a reservoir having several horizontally disposed cylindrical tanks in fluid communication and arranged in one or a few vertical planes. A portion of a lower-most tank of the reservoir is below the plane including the axle for the wheels; and the respective centers of gravity of the engine, the fuel tank, and the reservoir are arranged for relatively greater stability. A control system for the engine, generator, and compressor provides priority response to air demand and/or priority response to electrical power demand by reducing lower priority loads on the engine prior to increasing engine speed. A throttle controller moves the engine throttle from high speed to low speed in response to low demand for compressed air in combination with low demand for electrical power. The throttle controller includes a low demand valve and throttle positioning air cylinder.
