Section 5: Operation
Water cleanliness is very important. Use only clear,
clean, cold water that has been filtered to a minimum of three microns
before the high-pressure pump.
5.1 Use only thoroughly trained operators to perform cleaning operations
with the waterblast setup.
5.2 The person controlling the blast nozzle must be the gun operator. Do
not allow a secondary or remote operator to be the control gun operator.
5.3 The waterblast operator must be made aware that the blast nozzle’s
discharge jet(s) can inflict serious body wounds.
5.4 Place barricades with warning signs or barricade tape around work
area. This includes the waterblast unit and all high pressure hoses.
5.5 Before starting to blast, check for adequate hose length. The water-
blast operator should get into blasting position and move around to make
sure that all hoses (air and high-pressure) from the Multi-Mode Valve are
free from obstructions and are not tangled.
5.6 Make sure that the oil flow through the system from the oiler is set
correctly. To set the oiler, close off the flow control knob by turning it
clockwise; then turn the adjustment knob counter-clockwise approxi-
mately 2 turns.
5.7 Once the system is completely connected, adjust outlet air pressure
to between 80 psi and 90 psi using regulator knob. (90 psi is the maxi-
mum inlet air pressure of the air motor for the Tornado Spinner Gun).
5.8 With no nozzles installed in the gun or the Multi-Mode Valve, start
the waterblast unit and engage the pump according to the unit startup
procedures. Allow the pump to run for a minute or two with water exiting
through the Multi-Mode Valve dump port. Verify that no water is exiting
the gun.
