Cutting and Installation Tips for Coaxial Hard-Line (indoor only)
Issue 0.3 Not to Scale Figure 2-31 Page 2-69 (2-70 Blank)
Cutback and Installation of Shively Hard Line (indoor only):
Required tools:
 Reed tube cutter TC3Q: 3/8” to 3 ½” - require 1 Pc.
 Reed tube cutter TC6Q: 4” to 6 5/8” - require 1 Pc.
 Replacement cutter wheels, Reed part #63665 – 2PK-30-40 require 4 pack (8 wheels).
 Deburring tools Reed DEB3, require 1 Pc minimum.
 Replacement blade for DEB3, require 2 pack (20 blades).
 3M industrial scotch bright pad require 40 paces.
 Copper files set: round, half round and flat.
 Cotton cloths for cleaning.
Cutting tips:
 Cover both ends with plastic wrap to keep components clean and protected.
 Used gloves while handling the hard line and components to avoid hand grease.
 Avoid bending the hard line and refrain from using any parts that have been bent.
 Ensure there is inner teflon support in you cutting size.
 Check the screws on elbow sections and couplings to ensure they are tight before installation.
 Cut straight, smooth and clean.
 Put a clean cloth inside the tube before cutting to avoid swarf entering the line. Ensure that cutting wheels (or
alternatively hacksaw blades) are appropriate for cutting copper.
 After cutting, use a scotch bright pad to clean and smooth the cutting area.
Cutting and installation (for use with non-pressurized indoor hard line):
 Follow the manufacturer’s instructions.
 Draw a pencil line where the flange or coupling should reach when assembled (based on manufacturer’s
instructions). This will ensure a secure fit when pieced together.
 Starting from a fixed reference point (transmitter output), perform the outer vertical cut first, then clean the cut
end.
 Perform the inner cut according to the Shively instructions (inner cut piece always shorter than the outer cut
piece), clean the cut end, and install the anchor connector. Assemble the flange with the outer cut piece
and tighten the flange screw (be sure there is sufficient Teflon spacer between inner and outer pieces). Check
the rigid line vertically with a level.
 Install a vertical support if required (typically used for sections longer than 1.2 meters).
 Install coupling in the other vertical end and install the elbow section. Tighten the coupling screws well.
 Continue assembly of horizontal hard line sections and supports.
Maintenance:
 During operation and routine maintenance, check the hard line outer temperatures (especially elbow and
coupling sections) for any heat.
 During maintenance, check that the elbow and coupling sections remain securely tightened.
 Keep the assembled pieces clean.
