FEED TAP
™
OPERATOR'S MANUAL
2. Assemble Feed Tap™ to the pipe.
A . Clean area of pipe where drilling will occur. On
ductile iron and cast iron pipe use a Reed DS12 or
DS36 Descaler.
B. Place service saddle on the pipe and tighten down.
C. Attach the appropriate corporation stop valve to the
service saddle.
D . Assemble the Feed Tap™ with the correct size
corporation adapter, pilot drill, shell cutter, and
magnetic coupon retainer. For optimum thread life,
use plumber's thread seal tape on the male threads
of the main sealing unit prior to attaching the
corporation adapter.
NOTE: The 1" IPS Coupling Nut must be used with the
1" AWWA - 110 Compression Corporation Adapter.
E. Lubricate the teeth of the shell cutter generously
with Reed Tapping Compound #98425 or #99139.
F. Lubricate the o-ring inside the corporation adapter
with Reed tapping compound. This does not apply
to NPT corporation adapters.
G. Attach the Feed Tap™ assembly to the corporation
stop. Tighten the corp adapter to the corp stop using
the RCORP wrench.
H. Verify corporation stop will shut with pilot drill and
shaft retracted.
HELPFUL HINT: Take note of, or measure, the location
of the Independent Feed Control so that when you are re-
tracting the cutter back out of the pipe and valve you know
how far you have to retract it in order to allow the valve to
close.
I. Attach the drill motor onto the boring bar of the
Feed Tap™ and tighten the chuck.
J . Open the bleed-off valve.
3. Completing the Tap
A . Open the corporation stop and the bleed-off valve
on the Feed Tap™.
B. Using the independent feed control, bring the tool
in contact with the pipe surface. Do not run the drill
motor without controlling the independent feed
control, by hand, at all times. The feed control can
self feed too quickly if it is not controlled constantly
by the operator. If it self feeds, the pilot drill could
jam into the pipe which would damage or break it.
The user must always keep ahold of the indepedent
feed control when the boring bar is in motion.
C . Drill through the pipe by rotating the drill clockwise
and applying slow steady pressure using the inde-
pendent feed, turn in a clockwise direction. Water
coming from the bleed-off valve does not indicate
the shell cutter has completed its cut. The operator
will notice that there is no more resistance when
turning the Independent Feed once the shell cutter
completes the cut through the pipe wall.

OPTIONAL: To use magnets as coupon retainer,
place magnets in orientation as shown in diagram.
Use 1/4" diameter magnets for 3/4"-1" diameter
Shell Cutters. Use 3/8" diameter magnets for
1-7/16" to 1-3/4" diameter. Do not use magnets on
shell cutters larger than 1-3/4" diameter.
NOTE: The slow speed setting on the drill motor is rec-
ommended. This gives the user the best control of the tool
and is best for the longevity of the carbide shell cutters and
pilot drill. Higher speeds will create excessive heat and also
dislodge magnets resulting in lost coupon.
WARNING: Give the feed screw a couple extra turns to
ensure that the shell cutter has completely cut through the
pipe wall. If the coupon is not completely cut, it could strip
off the coupon retaining magnet when retracting the shell
cutter back out of the pipe.
4. Tool Removal and Storage
Refer to page 3-4 for details.
TOOL CARE AND MAINTENANCE
• The o-ring should be lubricated regularly with grease.
Reed Tapping Compound may be used for this purpose.
Lubricate the o-ring by disassembling the Main Sealing Unit
from the Feed Screw using the wrench flats. Apply grease
to the shaft and o-ring and reassemble. It is not necessary
to completely take the Main Sealing Unit off the Boring Bar
(Shaft). If it is necessary to remove the Main Sealing Unit
from the Boring Bar, the following items must be removed
first: any Shell Cutters, any Magnetic Coupon Retainers, the
Pilot Drill Bit, and the Threaded Washer on the end of the
Boring Bar. Also make sure that the Set Screw that holds in
the Pilot Drill Bit is either removed or screwed in so that it is
not sticking out beyond the surface of the shaft.• Keep the
threads on the independent feed nut and screw clean. Build
up in the threads will cause wear and make the tool difficult
to use. If cleaning is needed, use a soft bristle brush and
water.
• Water and mud on moving parts can cause corrosion and
result in feeding problems. Keep machine clean and lubri-
cated to help eliminate problems.
• Magnetic Coupon Retainers should be wiped clean after
use.
