RT3422 Tapping Tool
Excessive feeding of the cutter may result in high
torque feedback to the operator and could wrench
or injure arm.
Continue to drill through the main until no resistance
is felt when advancing the feed. Stop immediately if
only the "remaining unusable stroke" remains to be
used. Continuing past this point could cause pene-
tration through the far side of the pipe.
DO NOT tap through the bottom of the pipe.
6. The drilling into the pipe is now complete. The valve
and saddle as well as the tool are now filled with
the media in the pipe. Turn the sleeve counter-clock-
wise until all the threads of the bronze feed screw are
exposed and the sleeve comes to a halt. This action
has fully retracted the cutter and the coupon. Close
the corporation stop or valve. Should it be difficult to
close the valve (due to chips from the drilling opera-
tion), attach a hose to the bleed valve assembly if it is
not already there and open the bleed valve to "wash"
away as many chips as possible. Then rock the
valve open and closed until it can be completely
shut-off. It is vital that the valve is closed before pro-
ceeding. If the bleed valve assembly is in use it may
be closed as well and the hose removed. Note that
this hose will contain residue of the same media that
is in the pipe.
7. Remove the ratchet or power tool from the hex on the
drive shaft. Place a wrench on the valve to prevent it
from disconnecting as the valve adapter is unscrewed
from the valve with another wrench. Be prepared
for the tool to suddenly come free and for it to spill out
any media it contains. If the drilled pipe was dry, be
aware that the cutter may be hot.
8. The new plumbing may now be attached to the out-
let end of the valve. After that, all that is required is to
open the valve to activate the newly installed system.
9. To remove the coupon from the cutter, turn the
sleeve clock-wise until the cutter is exposed. Shell cut-
ters have a hole or slot to allow the coupon to be
pushed out. Remove the cutter if required, in order to
make coupon removal easier. If using a coupon re-
taining pilot bit, squeeze the spring retainer to allow
the coupon to slide off. After completing all taps of
this configuration, continue to step 10. If more taps
are needed, reinstall the cutter and start again from
step 1.
10. Remove the valve adapter, drill or cutter, pilot drill (if

used), saw adapter (if used) and extension from the
tool. Turn the sleeve clockwise until all the threads of
the bronze feed screw are hidden and the tool is
fully collapsed. Simply wipe all the components until
clean and dry and store them in the toolbox.

This procedure should only be conducted by a qualified
service technician.

Tool Disassembly Procedure

1. Turn the sleeve clockwise until all the threads of the
bronze feed screw are hidden and the tool is fully col-
lapsed. Place the tool horizontally on a table so parts
do not fall out.
2. Locate and remove the setscrew from the side of
the red cap.
