Hand-held tool for cutting with high pressure water

A method of cutting an object with a cutting apparatus for cutting using a pressurized jet of fluid from a high pressure fluid source, comprising the steps of, in combination:

• providing a cutting apparatus comprising a hand-held tool, a hose for delivering pressurized fluid to said hand-held tool from said high pressure fluid source, and a nozzle at a distal end of said hand-held tool, said nozzle directing the flow of pressurized fluid to create a pressurized jet of fluid when pressurized fluid passes said nozzle having a tapered portion with a frusto-conically shaped outer surface sized and shaped for direct contact with the object and an exit nozzle located at a small diameter end of the tapered portion;
• supplying electrical power to a relay switch;
• contacting the object with the tapered portion of the nozzle;
• depressing a trigger switch on said hand-held tool, thereby supplying power to a pneumatic solenoid valve, said pneumatic solenoid valve opening and supplying air to a pneumatic valve connected to said high pressure fluid source and said pneumatic solenoid valve, said pneumatic preventing flow of high pressure fluid to said hand-held tool when said trigger switch is disengaged, said pneumatic valve being opened by air received from said pneumatic solenoid valve through a hose when said pneumatic solenoid valve is activated by depressing said trigger switch;
• and,
• cutting said object by moving the nozzle along the object while maintaining contact with the object and directing said pressurized jet of fluid from said hand-held tool at said object along a cut path.
