navigate and clean 6" pipes with up to 90° bends. The 6" J-Force has
front, side, and rear jets that clear blockages, clean, and provide thrust
to propel the tool down the pipe. The nozzle comes equipped with an
eddy-current braking system which controls rotation speed for maximum
cleaning power and minimum wear.

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. July 2020 PI-178... - 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 11. Properly tighten all high pressure connections. All NPT connections must have a minimum engagement of four (4) threads. Pipe (NPT) connections should be made up hand tight plus two (2) full wrenched turns. Do not tighten NPT threads past two (2) wrenched turns. Use wrench flats (when available) or a properly adjusted smooth jaw plier wrench (JS PN 64119) for tightening components.
- Page 6 18. If equipment malfunctions or a system malfunction is suspected, immediately stop cleaning activity and relieve the pressure in the system before attempting any repairs. Always follow the manufacturer’s repair instructions. 19. Only trained persons should be authorized to perform any mainte- nance or repair.
- Page 7 7. Do not use a pressure relief valve as a combination relief and throttling device. 8. Keep relief valve dry during freezing conditions. NOTE: Pressure relief devices are imperative for the protection of both operator and equipment from dangerous over-pressurization. HIGH PRESSURE HOSE 1.
- Page 8 Wrench connection 1 1/2 - 2 turns past hand tight. A minimal thread engagement of four (4) threads should exist on all Jetstream NPT pipe connections. Use wrench flats (when available) or a properly adjusted smooth jaw plier wrench (JS PN 64119) to tighten nozzle.

Contact JETSTREAM for additional information regarding these products. 9. Use only nozzles designed for use with flex lances (i.e. nozzle drilled with sufficient rearward orifices so nozzle pulls lance through tube.)
- Page 10 this clearance should be greater. Insufficient side clearance may cause lance to blow back toward operator. 4. Be sure nozzle, lance and adapter thread sizes are compatible before installing nozzle and adapter on lance. Do not use a rigid lance that has damaged or missing threads.

If repaired equipment performance is questionable, call manufacturer of repair parts for assistance.

Page 14: Section 3: Preparation For Use
Section 3: Preparation for Use 3.0 The 6” J-Force is mounted to a flexible rubber waterblast hose that allows it to navigate 6” pipes with bends up to 90°. 3.1 Before use, disassemble the 6” J-Force and inspect the mandrel and bushing for wear, damage, o-ring condition, etc. -
Page 15: Section 4: Setup
NOTE: Nozzle configurations must be carefully selected to ensure that they provide the necessary pull and torque. If a non-standard configura- tion is required, contact a Jetstream representative to verify that it is safe and that the tool will function properly. -
Page 16: Section 5: Operation
Section 5: Operation 5.0 OPERATING J-FORCE As per the WJTA-IMCA Recommended Practices, all operators shall follow the OSHA regulations for personal protective equipment. (OSHA guidelines for Personal Protective Equipment are available in document number 3151-12R 2004, which can be obtained from www.osha.gov.)
