Align the slot on the <br />too/ with the key on the /Met tube and insert the tool <br />down Sea Figure 9A. <br />Figure 9A Figure 10.41 <br />STEP 10k TIGHTEN TFIE 71SO-TOOL <br />Use the three view holes to ensure that the tool seats <br />out flat against the top of the inlet tube To pc'eVEnt <br />vertical movement of the tool during drilling, hand <br />tighten all three knobs Pvrn ty to the upper drop tuba <br />see Figure 10A. <br />STEP 11141, PREPARE DRILL AND IT <br />CunArrn that the stop on the 3/i 6' +drill bit supplied <br />with the 71SO-TOOL kin the correct position before <br />drilling. The stop Is factory installed at a distance be- <br />tween 24 to 2-1/16' from the tip with the 7150-TOOL if <br />the stop is not at the correct position it must be frxed <br />before drtIling. <br />ournoN3 If the drill stop is not in the proper loca- <br />tion failure of a pressure decay leek test may result. <br />Tip to stop dimension must be <br />2" to 1-1/16'. <br />Frgsatie 11A <br />STEP 12k DRILL HOLES <br />With the inlet tube and 7150-TOOL in place, carefully <br />drill a3/U5 diameter hole In the upper tube using the <br />drill bushing in Vie knob as a wide. The drill stop is po- <br />sitioned so It will bottom opt against the knob after the <br />bit has &flied through the upper drop tube. If the stop <br />is positioned wvon9 either no hole will be drilled, or a <br />thiough hole could potentially be drilled tibrotroh the <br />}nret tube. If no hole is drilled return to step 1 tA anti <br />check the stop dimension.
