Pressure Waterjetting Equipment” published by the Waterjet Technology Association, as well as any applicable OSHA regulations, standards and guidelines. Should any questions arise concerning safe and proper procedure, contact JETSTREAM prior to the installation or use at (800) 231-8192 or (832) 590-1300. March 2020 PI-120... - Page 4 GENERAL WATERBLAST 1. Use only clear, clean water in high pressure system. 2. Place barricades with warning signs or barricade tape around work area. 3. Outfit all operators with Personal Protective Equipment (PPE). Hard hat with plastic face shield, rainsuit, non-skid knee boots with metatarsal protection, gloves, ear protection and body armor rated for operating pressures are considered minimum safety equipment.
- Page 5 Use wrench flats (when available) or a properly adjusted smooth jaw plier wrench (JS PN 64119) for tightening components. Avoid using pipe wrench as wrench marks will cause high pressure components to crack and fail. 11. All high pressure hose connections require a hose restraint (whip check), including connection at fluid end discharge.
- Page 6 18. Only trained persons should be authorized to perform any mainte- nance or repair. 19. Following any repairs, the system should be operated at low pressure for test. Bring equipment up to operating pressure slowly. 20. For shutdown in freezing conditions, even for brief periods, drain water from all components.
- Page 7 3. Prior to use, thoroughly check control gun or control device for smooth and proper operation. Control guns and control devices should also be checked for proper operation before each operating shift. Do not use any control gun or control device that has not been checked before your operating shift.
- Page 8 13. All electric throttle control cords should be rated for wet conditions. All cord connections and switches should be kept out of water. 14. Any hose used for transporting dump water back to pump should have a large enough diameter and short enough length so that potentially dangerous back pressure is kept low.
- Page 9 HIGH PRESSURE HOSE 1. Read General Safety section prior to connecting high pressure hose. 2. Do not use a high pressure hose with a burst rating less that 2.5 time the pressure at which it will operate. 40,000 psi operating pressure high pressure must have a minimum 100,000 psi burst rating.
- Page 10 Use wrench flats (when available) or a properly adjusted smooth jaw plier wrench (JS PN 64119) to tighten nozzle. Avoid using pipe wrench as wrench marks will cause nozzles to crack and fail. 7. Blocked orifice(s) can cause excessive system pressure and failure. If orifice(s) appear clogged or partially blocked with dirt or debris, remove nozzle from MagJet and clean immediately.
- Page 11 6. Test repaired equipment carefully and thoroughly before putting it into service. Do not put any piece of repaired equipment into service if its performance is questionable. If repaired equipment performance is questionable, call manufacturer of repair parts for assistance. This section includes most of information included in the yellow JET- STREAM SAFETY WARNING pamphlet (PI-082), with the exception of the flexible and rigid tube cleaning sections.

Section 3: Preparation for Use 3.0 BEFORE PUTTING TORNADO GUN INTO SERVICE NEW TORNADO GUN 3.1 Check the gun carefully upon removal from its shipping container for damage. DO NOT assemble or use the gun if any damage is apparent or the condition of any component is questionable. - Page 15 3.4 The FXG2 Tornado Gun must be inspected in conjunction with the 40K Remote Control Valve. With the nozzles removed from the nozzle head, the system water should be turned on and both triggers of the Tornado Gun should be squeezed and released. The 40K Remote Control Valve should be checked for air leaks, and checked to make sure that the Control Valve opens and closes correctly.

Page 16: Section 4: Setup
Section 4: Setup 4.0 CONNECTING TORNADO GUN 4.1 Use only 40,000 psi rated fittings and hose for connecting the gun. They should have a minimum burst rating of 100,000 psi. 4.2 Use of a 6’ safety whip hose is recommended. Safety whip hoses can be replaced frequently for high operator safety. -
Page 17: Section 5: Operation
Call Jetstream for assistance if two or more Tornado Guns must be used in the waterblast system. - Page 18 5.3 Make sure that the air regulator is set correctly. The pressure should be set for no lower than 80 psi and no higher than 120 psi while the gun is in operation (not at rest). To set the proper air pressure, pull up on the air regulator adjustment knob and turn clockwise for more air pressure and counter-clockwise for less air pressure.
- Page 19 require seal replacement. Do not blast with a leaking HP seal as this will allow hot water to drip onto operator’s hands and cause water to flush grease from the swivel bearings and damage the swivel shaft. 5.10 Make sure that no water is flowing out of the dump port of the Remote Control Valve while blasting.

- Page 22 6.0 FXG2 TORNADO GUN MAINTENANCE 6.1 REPLACING THE HIGH PRESSURE SEAL If water begins to leak from weep holes at rear of gun during operation, replace high pressure seal as follows: 1. Remove hose support burst shield (6) and disconnect high pressure hose.
- Page 23 3. Remove seal adapter (4b) by pulling back away from gun. Push out worn seal from adapter ID using blunt object. Be careful not to dam- age seal adapter. 4. Clean all dirt and debris from rotary swivel body and check condition of the swivel shaft.
- Page 24 5. Install seal (PN 53707) onto shaft cone-end first. O-ring should face away from gun as shown. 6. Push seal adapter over seal until face bottoms on swivel body. Install and tighten retaining nut. Be sure the retaining nut is seated against the housing shoulder before operating.
- Page 25 7. Connect supply hose to back of seal adapter and re-install hose sup- port burst shield. Do not operate without hose support burst shield. 8. The gun should now be ready to use. Increase pressure slowly until desired blast pressure is reached. 6.2 REPLACING THE DRIVE BELT If barrel stops rotating, or rotates erratically, the drive belt may be dam- aged.
- Page 26 7. Pull shaft/bearing assembly from body using four jacking setscrews or Jetstream puller kit (PN 67540) and inspect shaft and/or bearings for damage or improper operation. Removing Shaft 8. To replace bearings, press bearings off shaft using an arbor press or Jetstream puller.
- Page 27 Removing Large Bearing Removing Small Bearing Pressing New Bearings On Shaft 9. Replace lip seals in mounting plate if necessary. 10. Re-assemble shaft/bearing assembly into body and install to mount- ing plate using the six 10-32 capscrews. Torque capscrews to 60 In-Lbs.
- Page 28 Use only the correct seal kit to repair your control gun. Failure to use the correct pressure-rated seal kit could result in seal fail- ure and possible control gun damage and operator injury. See YouTube for videos showing FXG2 Tornado Gun service. PI-120 March 2020...
