A device for use in connection with the operation of high pressure equipment, such as a sewer and/or catch basin cleaner which has a hose reel for the water hose, and includes a protective shield which can be located in at least two positions. A first position is an operator protection position used when the machine is pumping fluid. A second position is a position in which access may be had to a hose reel or other machine components. An interlock coupled to the shield prevents high pressure fluid from being passed through the hose when the enclosure is in its second position. The shield of the present invention can be used in conjunction with a second, flexible tubular sleeve to provide head-to-toe protection for the operator of such equipment.
