1. Identify pipe to be traced. Remove surrounding soil to expose pipe around
the entire circumference approximately 2 feet (minimum) in length. It may
be necessary to install supports under the pipe to prevent buckling once work
begins.
2. Install entry saddle per manufacturer instructions and follow your com
-
pany’s procedures. Remove Completion Plug from saddle and store in clean,
safe place.
3. Install necessary adapter fittings (if any) to enable installation of valve in
Step 4. Follow company procedures to ensure proper seal is achieved.

The following instructions describe an example set-up using a mechanical saddle. Other types of saddles
may be used, however the basic process will be similar. Always follow your company procedures.
8. Measure the distance between top of Shortcut Valve and lower wall of pipe to be inspected.
9. If the Tool carriage does not move freely, try adjusting both Lock Handles so clamps tighten on Guide Rods
very slightly. This will help square-up Carriage so it moves freely.
10. Move the Tool to a clean, dry place. Verify Tool is clean and lubricated. Apply grease to Gear Rack and
Gear as necessary. Wipe Guide Rods clean and lubricate with company approved spray lubricant as needed.
11. Be certain Shoe is secured tightly to launch tube of the Tool.
12. Turn Hand Wheel so Carriage retracts completely to top and compresses the Spring. Verify lower edge of

13. If adjustment is required to allow Shoe to retract further, loosen Lock
Collar located inside Lock Collar Housing. The Lock Collar screws are
accessible through slots in the Lock Collar Housing. Slide Launch Tube to
retract the Shoe to desired position then tighten Lock Collar screws.
14. Turn Hand Wheel to lower Launch Tube the approximate distance
obtained in Step 8. Use a permanent marker to mark position on Launch
Tube. This will provide a visual indication when Launch Tube is inserted
completely into pipe.
15. Use Hand Wheel to fully retract Carriage.
16. Lock Carriage using the two Lock Handles. ***IMPORTANT***
When pressure is applied to tool from gas main, carriage raises suddenly if not locked in place.
