HOW TO USE YOUR
“EASY TAPPER”™ MODEL #XTC-1.7S
TAPPING MACHINE

1. Verify the source, destination, type, contents, and pressure of the line you are about to tap. Note: Maximum tapping pressure for the
Model # XTC-1.7S is 1,470 P.S.I.G. at 100 degrees F.

2. A Tapping saddle of proper size can be tightened on to the main line. (In some cases a thread-o-let or malleable iron nipple can be arc welded to the main line).

3. A short nipple is then threaded into the tapping saddle.

4. A "full port" ball valve is then threaded onto the short nipple. Note: Gate valves are not recommended in this case, because shavings from the drilling process tend to collect in the gate chamber, preventing the gate from closing all the way.

5. The XTC-1.7S Hot Tapping Machine ships ready to use, by first installing 2 strips of pure graphite packing under the packing nut at the back of the machine front. Install the second strip with the joining seam on the opposite side from the first strip, to create a better seal. Grease has been factory installed in the bearing box, and an o-ring seal for the drive shaft has also been factory installed. Additional packing can be added at any time, even during the tapping process, simply by withdrawing the drive shaft and cutter back out of the branch line valve and then closing the branch line valve while packing is installed. To add packing, loosen the packing nut and install as listed at the beginning of section 5 (above).

6. Now select the proper cutter, arbor and pilot bit, assemble, and install the hexagon arbor shank into the hexagon receiver (coupler), on the forward end of the drive shaft.

Note: refer to the cutter information on the back side of these operating instructions for cutter size and recommended cutting RPM’s. The end of the pilot bit should be positioned to penetrate the wall thickness of the main line before the cutter teeth engage the wall of the main line. When using the Easy Tapper™ ‘coupon retaining pilot bit’, the spring-steel wire should pass through the wall of the main line before the cutter teeth begin cutting. The cutter and the pilot should now be tightened securely to the drive shaft.

7. At this point it is a good idea to verify that the cutter will slip through the branch line "full port" ball valve unrestricted.

Stainless Steel Tapping Procedures

Use a 1/4" Cobalt Pilot Bit. Position within the Bimetal Hole Saw to extend completely through the wall of the pipe before the teeth of the hole saw contact the wall of the pipe. As the Cobalt Pilot Bit penetrates the wall of the main line, fluid will rush into the tapping machine body and will act as a coolant for the Bimetal Hole Saw.
