     ASSEMBLY INSTRUCTIONS – TUBE BITE HOSE COUPLINGS (END STYLE 850)
 ASSEMBLY INSTRUCTIONS FOR:
TUBE BITE HOSE COUPLINGS (END STYLE 850) CONT.
If safe to do so, the bent tube part can be cut from the old assembly and reused. (NOTE: for combined hose and tubing assemblies with Metric Tubing, Male DKL or DKS Hose Coupling can be used with M6L or M6S Metric Nut and Cutting Ring).
   STEP SEVEN
                                                        • Disassemble the Nut from the Coupling.
• Inspect the front edge of the Compression Olive. For correct assembly, the
cutting edge of the Compression Olive must have formed a shoulder on the tube at least 50% as high as the cutting edge, all the way around the tube3.
  STEP EIGHT
                            • Attach the T2850, T4850 or 6850 coupling onto the hose, without the tube, Nut and Compression Olive connected to it.
• Refer to the appropriate Assembly Instructions for the Hose Series and Coupling Series being assembled.
• Do not assemble the coupling onto the hose until Steps One to Seven are completed.
    STEP NINE
                                                      • Re-assemble the tube, Nut and Compression Olive onto the T2850, T4850 or 6850 end of the hose assembly.
• Nut will turn easily until an increase in force is required. At this point, orient the bent tube assembly pointing to the correct direction if required.
• Holding the Hex of the T285, T485 or 685 coupling insert with one spanner, with another spanner tighten the Nut down a further 1/6 of a turn as a minimum, but no more than 1/3 of a turn, to complete tightening operation.
  NOTES
   1 This is a general rule, and may vary slightly with different tubing materials.
2 In some instances (especially when using soft or thin-walled tube), to
prevent excessive tube collapse, it may be necessary to support the inside
of the tube with a mandrel prior to setting the Compression Olive.
3 Note that the maximum allowable radial collapse of the inner tube
diameter is 0,25 mm (.010”).
