4. The line that connects the sampling needle to the sample syringe is
clipped to the upper-right side of the needle arm (see Figure 5-10 ).
Using a 2.5-mm Allen wrench, remove the M3 screw that attaches the
clip to the sampling arm. Remove the clip, and then remove the
tubing from the clip.
NOTE Some needle arms have a clip that is open at the
top. This type of clip does not need to be
removed. To remove the tubing from the clip,
pull the clip out slightly and push the tubing up
and out of the clip.
5. Measure the distance from the yellow sleeve on the sampling needle
assembly line (see Figure 5-10 ) to the needle. When installing the
new sampling needle assembly, position the sleeve on the new line
the same distance from the needle.
