RT3422 Tapping Tool

a) Having ensured that the tool is in the shortest, col-
lapsed, position and having selected the proper size
extension, hold the spindle by the flats at the end and
screw the extension into the end of the spindle. This
only has to be hand tight as the threads will be tight-
ened by the operation of the tool (Figure 1).
b) Inspect the "o-ring" seal in the valve adapter (replace
if damaged) and holding the bronze feed screw by the
flats, assemble the valve adapter onto the bronze
feed screw. This should be done by hand as the op-
erator will feel first the seal engaging and then feel the
adapter reach an abrupt stop as the bronze feed
screw "bottoms out" in the valve adapter (Figure 2).
c) Select the cutter to be used for this particular opera-
tion from the chart on the next page. Note that the pilot
drill and hole saw adapter may not be required de-
pending on the actual cutter selected. If the selected
cutter requires a hole saw adapter, screw it into the
end of the extension. CI/DI and PVC cutters do not re-
quire use of hole saw arbor. As before, this only has
to be hand tight (Figures 3 and 3a).

ular operation to ensure that it is in good working
order and screw it into the hole saw arbor if present or
directly into the extension as required. As before,
this only has to be hand tight (Figures 4 and 4a).
