Section 3: Preparation for Use
3.0 The 3” J-Force is mounted to a flexible rubber waterblast hose that
allows it to navigate 3” pipes with bends up to 90°.
3.1 Check that the 3” J-Force is free of debris and rotates smoothly. If
not, disassemble the 3” J-Force and inspect the mandrel and bushing for
wear, damage, o-ring condition, etc. and repair or rebuild as necessary.
3.2 Check the condition of the wear ring and attaching screws. Replace if
worn excessively.
3.3 See Flow Charts in Appendix C to choose nozzle configuration, flow
rate, and desired operating pressure. The 3” J-Force is equipped with
two forward-facing ports at 10°, two forward-facing ports at 45°, two
radial ports at 100°, and two rearward-facing ports at 135°. Choose the
nozzle configuration based on the type of cleaning application and desired
operating pressure and flow.
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.
3.4 Install P1 nozzles into the rotor. Apply Loctite 545 Thread Sealant to
seal and retain the P1 nozzles. Torque nozzles to 100 lb∙in. For leak free
operation, wait 12-24 hours for thread sealant to cure.
