An improved system whereby a high pressure hydraulic hose can be unwound from a hose reel while under pressure, and moved laterally to a remote manhole, without manual restraint. The total system utilizes: an improved down the manhole sewer guide for the hose, a self-contained manhole feed frame which can be slid under the hose and which utilizes the pressure in the hose to lock it in place, a stationary rotary guide wheel positioned on one side of the hose reel, and an improved traverse mechanism which will accommodate lateral movement of the hose between the guide wheel and the hose reel.
