PRODUCT INSTRUCTIONS
The 4” J-ForceTM Gen III is a self-powered rotating nozzle designed
to easily navigate and clean 4” pipes with up to 90° bends. The 4”
J-Force Gen III 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.

SECTION 1: SAFETY
This information was prepared to aid in the identication of potentially
unsafe conditions when using high pressure waterblast equipment. It
should be noted that other potential hazards may exist which might
have not been mentioned in this brochure.
In all cases, JETSTREAM products are sold with the understanding that
the purchaser agrees to thoroughly train all operating and maintenance
personnel in the correct and safe installation, operation of maintenance
of waterblast equipment and to provide adequate supervision of
personnel at all times.
Read the following in its entirety before connecting, operating or
repairing equipment. Purchasers and operators also should be familiar
with the current version of the “Industry Best Practices for the Use
of High 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 [phone] or
[phone].
Incorrect Use of High Pressure Waterblast
Equipment May Cause Serious Injury
Read these instructions in their entirety
before using any JETSTREAM products.

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. Outt 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. Proper
respiratory protection is required where dangerous fumes or dust is
present or created by the waterblasting operation. Follow applicable
OSHA regulations, standards and guidelines regarding the use of
respiratory protection if harmful fumes or dust is present during, or
created by the waterblasting operation.
4. Use products intended for high pressure waterblasting only.
5. No product should be altered without written consent of the
manufacturer.
6. Read and follow all manufacturer’s instructions prior to using any
waterblast product. Contact manufacturer.
7. Thoroughly review alternative methods before initiating any
potentially dangerous waterblasting operation. Fully automated, semi-
automated, and/or mechanized methods should all be considered rst.
Contact the applicable waterblasting manufacturers for assistance and
recommendations.
8. The operator handling the cleaning device (with nozzle) must always
have control of water pressure. A surface cleaning operator should
operate a trigger style control gun capable of instantaneously stopping
pressure to nozzle. A tube cleaning lance operator should operate a foot
gun capable of instantaneously stopping pressure to the lance.
9. Inspect the condition of all components prior to use. Use no items
which are in questionable condition.
10. Check the condition of thread connections prior to the make-up of
any high pressure connection. Use Teon tape and anti-seize on male
pipe (NPT) thread for sealing purposes. Do not let tape overlap the male
pipe thread end. Tape fragments may enter system water stream and
clog nozzle’s orices.
Do Not use a component with missing or damaged threads on the
high pressure connections.

5PI-197January 2022
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 ats (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.
12. All high pressure hose connections require a hose restraint (whip
check), including connection at uid end discharge.
13. Before attaching a nozzle to the control gun or tube cleaning lance,
operate the pump at low speed to purge dirt and debris from system.
Dirt and debris can clog nozzle orice(s) and cause excessive
system pressure which could lead to a lance failure.
14. With nozzle installed, operate the pump at a low speed (low
pressure) for test. Should system repairs or adjustments be necessary,
stop pump and relieve all pressure before making required repairs or
adjustments. The pump operator should watch the nozzle operator
at all times in case any difculty arises and it becomes necessary to
depressurize system. If the pump operator does not have a clear line
of sight to the nozzle operator, it may be necessary to have another
employee available to communicate between the nozzle and pump
operators.
15. With the system operating properly, increase pump speed
slowly until operating pressure is reached and adjusted. Pressure
adjustments should always be made slowly. The nozzle operator shall
be warned before any pressure adjustment is made by the pump
operator. A sudden change in reaction force may cause the nozzle
operator to lose balance.
16. Use minimum pressure required for cleaning. Do not exceed the
operating pressure of the system’s lowest pressure-rated component.
All equipment pressure rating markers and warning tags should be left
intact.
17. Waterblast operators must be made aware that the cleaning
nozzle’s discharge jets(s) can inict serious body wounds.
Supervisors should demonstrate the potential danger of discharge
jet(s) by showing all new operators the effect of a waterjet by cutting a
scrap piece of wood such as a 2” x 4”.
