the Port Cutting Guide<\/h2>\n<p>Slide the Port Cutting Guide over the CMT tubing down to Port 1. Align the notch stamped &#8220;1 &#8221; on the Port Cutting Guide with the line you drew along the Channel 1 identifier. Position the Port Cutting Guide so that the depth mark &#8220;+&#8221; (indicating the centre of the Port) is visible in the window in the centre of the Port Cutting Guide (Figure 8). Secure the Port Cutting Guide to the CMT tubing by tightening the knurled Locking Bolts on the underside of the guide (Figure 9). Tighten the bolts, by hand only, to prevent the Port Cutting Guide from moving.    <\/p>\n<p>[\/et_pb_text][et_pb_image src=&#8221;https:\/\/www.solinst.com\/wp-content\/uploads\/2024\/11\/fig5-cmt-port-cutting-guide-at-correct-position.webp&#8221; alt=&#8221;figure 8 cmt port cutting guide&#8221; title_text=&#8221;Figure 8 &#8211; CMT Port Cutting Guide&#8221; align=&#8221;center&#8221; _builder_version=&#8221;4.27.2&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][\/et_pb_image][et_pb_text _builder_version=&#8221;4.27.2&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<p style=\"text-align: center;\"><span>Figure 8 &#8211; CMT Port Cutting Guide<\/span><\/p>\n<p>[\/et_pb_text][et_pb_text _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;e910b435-fe18-45d2-b351-bda808b1a267&#8243; hover_enabled=&#8221;0&#8243; border_width_all=&#8221;1px&#8221; border_color_all=&#8221;rgba(0,0,0,0.23)&#8221; global_colors_info=&#8221;{}&#8221; sticky_enabled=&#8221;0&#8243;]<\/p>\n<div class=\"boxColumn\">\n<div class=\"boxContent\">\n<h3><strong>Note:  <\/strong><\/h3>\n<div class=\"boxWrapper\">\n<div class=\"boxColumn\">\n<div class=\"boxContent\">\n<div class=\"boxWrapper\">\n<div class=\"boxColumn\">\n<div class=\"boxContent\">\n<p>When using the Port Cutting Guide, ensure that the cutting bolts are located below the number 1 on the front of the Guide.

Use the hex wrench to tighten the Cutting Bolt. Tighten the bolt a few revolutions, then loosen it one revolution. Continue doing this until the Cutting Bolt &#8220;bottoms out&#8221; (Figure 10). Remove the Cutting Bolt. There should be a plastic disc inside of the cutting bolt. If there isn&#8217;t, re-insert the cutting bolt and repeat the cutting process (make sure that the knurled Locking Bolts are tight). Push out the piece of plastic from the inside of the Cutting Bolt by inserting an Allen wrench through the small hole drilled in the head of the Cutting Bolt (Figure 11 ). Repeat this process to cut all three holes. The two upper holes will provide the port plug access and the lowest hole is the vent hole (Figure 12).         <\/span><\/p>\n<p>[\/et_pb_text][et_pb_text _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;e910b435-fe18-45d2-b351-bda808b1a267&#8243; hover_enabled=&#8221;0&#8243; border_width_all=&#8221;1px&#8221; border_color_all=&#8221;rgba(0,0,0,0.23)&#8221; global_colors_info=&#8221;{}&#8221; sticky_enabled=&#8221;0&#8243;]<\/p>\n<div class=\"boxColumn\">\n<div class=\"boxContent\">\n<h3><strong>Note:  <\/strong><\/h3>\n<div class=\"boxWrapper\">\n<div class=\"boxColumn\">\n<div class=\"boxContent\">\n<div class=\"boxWrapper\">\n<div class=\"boxColumn\">\n<div class=\"boxContent\">\n<p><span>For easy effective cutting, advance the cutter bolt in alternating increments of ~1.5 turns clockwise, and then 0.5 turn counter-clockwise, repeatedly.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p>[\/et_pb_text][et_pb_image src=&#8221;https:\/\/www.solinst.com\/wp-content\/uploads\/2024\/11\/fig7-cutting-port-holes-in-cmt-tubing.webp&#8221; alt=&#8221;figure 10 cmt port cutting guide &#8211; cutting out sampling port hole&#8221; title_text=&#8221;Figure 10 &#8211; CMT Port Cutting Guide &#8211; Cutting Out Sampling Port Hole&#8221; align=&#8221;center&#8221; _builder_version=&#8221;4.27.2&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][\/et_pb_image][et_pb_text _builder_version=&#8221;4.27.2&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<p style=\"text-align: center;\"><em>Figure 10 &#8211; CMT Port Cutting Guide &#8211; Cutting Out Sampling Port Hole<\/em><\/p>\n<p>[\/et_pb_text][et_pb_image src=&#8221;https:\/\/www.solinst.com\/wp-content\/uploads\/2024\/11\/fig8-removing-cmt-port-cuttings.webp&#8221; alt=&#8221;figure 11 cmt removing ldpe cutting plug&#8221; title_text=&#8221;Figure 11 &#8211; CMT Removing LDPE Cutting Plug&#8221; align=&#8221;center&#8221; _builder_version=&#8221;4.27.2&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][\/et_pb_image][et_pb_text _builder_version=&#8221;4.27.2&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<p style=\"text-align: center;\"><em>Figure 11 &#8211; CMT Removing LDPE Cutting Plug<\/em><\/p>\n<p>[\/et_pb_text][et_pb_image src=&#8221;https:\/\/www.solinst.com\/wp-content\/uploads\/2024\/11\/fig9-marked-cmt-tubing.webp&#8221; alt=&#8221;figure 12 cmt tubing port cutting setup&#8221; title_text=&#8221;Figure 12 &#8211; CMT Tubing Port Cutting Setup&#8221; align=&#8221;center&#8221; _builder_version=&#8221;4.27.2&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;][\/et_pb_image][et_pb_text _builder_version=&#8221;4.27.2&#8243; _module_preset=&#8221;default&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<p style=\"text-align: center;\"><em>Figure 12 &#8211; CMT Tubing Port Cutting Setup<\/em><\/p>\n<p>[\/et_pb_text][et_pb_text _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;e910b435-fe18-45d2-b351-bda808b1a267&#8243; hover_enabled=&#8221;0&#8243; border_width_all=&#8221;1px&#8221; border_color_all=&#8221;rgba(0,0,0,0.23)&#8221; global_colors_info=&#8221;{}&#8221; sticky_enabled=&#8221;0&#8243;]<\/p>\n<div class=\"boxColumn\">\n<div class=\"boxContent\">\n<h3><strong>Note:  <\/strong><\/h3>\n<div class=\"boxWrapper\">\n<div class=\"boxColumn\">\n<div class=\"boxContent\">\n<div class=\"boxWrapper\">\n<div class=\"boxColumn\">\n<div class=\"boxContent\">\n<p>If installing numerous systems, spare cutting bolts can be ordered, as they may become dull after repeated use.

Fit the &#8216;jaw tips&#8217; of the Oetiker pliers into each of the clamp&#8217;s &#8216;tunnels&#8217;. Squeezing\/closing the Oetiker pliers simultaneously draws the two tunnels together. With the two tunnels drawn together, push down on the tail of the clamp, so that the furthest retaining hook passes through the last slot.
