RECOMMENDATIONS
for MODEL MFT
Flange Facer
READ THOROUGHLY AND UNDERSTAND THIS PUBLICATION BEFORE
ATTEMPTING TO OPERATE THE EQUIPMENT.
DANGER! The application of this product requires an exposed rotating tool holder and cutting blade. It can
produce HOT, SHARP metal fragments requiring that eye, ear, and hand protection and other protective
clothing be worn at all times. Do not wear loose fitting clothing that may become entangled with the rotating
objects.
Elbow
Mandrel Mandrel
Support
Bushing
1. Install the appropriate elbow mandrel in the pipe
I.D. in accordance with the instructions provided with
the mandrel. For accuracy, the elbow mandrel is highly
recommended over the wedge sets. The mandrel
support bushing should also be installed to increase
rigidity and reduce the occurrence of chatter.

2. Mount the power unit/flange facer assembly onto the
centershaft by aligning the splines and engaging the
feed nut.
3. Install the low or high range tool holder (depending
upon the flange size) in the tool block.
A
NOTE: Make sure that the distance (A) between the
female slide block and the body is greater that the width
of the flange surface to be machined. Reposition as
necessary. All trip pins must be disengaged.
4. Assure that the area around the machine is clear.
Begin rotating the flange facer and advance the feed nut
until the insert makes contact with the surface. Stop the
machine and note the position of the handles on the
feed nut. Turn the feed nut counter clockwise 1/2 turn to
disengage the insert from the face.
5. Position the insert outside of the flange surface to be
machined by rotating the trip wheel with the ratchet and
socket.
6. Return the insert to the contact depth by turning the
feed nut 1/2 turn clockwise. See specifications below for
approximate adjustment dimensions. Lock the feed nut in
position by tightening the cap screw.
7. Clear the backlash by rotating the trip wheel clockwise
when looking at the nut by hand. Once you feel
resistance, position the next tip of the star wheel so it
points directly at the trip ring (model MFT) or bracket
(model MT). Failure to perform this procedure will result
in damage to the trip pins.
8. Proper adjustment of the gib is necessary for an even
cut and proper timing. The gib is properly adjusted when
there is resistance to turning the trip wheel by hand.
Adjustments are made by turning the gib screw
clockwise to loosen.
9. Engage the desired number of trip pins for the surface
finish required (See specifications below).
10. Allow the machine to run until the flange has been
completely resurfaced.

FLANGE FACING CONVERSION
Confirm the date of manufacturing for your
model MFT. Tools built before March of 2003 will
require that holes be drilled and tapped in the
housing to accept the trip ring. Typically, these
tools are returned to the factory for this process.
Should you elect to perform this operation,
contact the factory for exact location and sizes.
Once you have confirmed that your tool has the
appropriate mounting holes, proceed with the
following instructions.
Step 1: Remove the feed nut
handles (A) by unscrewing
them from the feed nut.
Step 2: Remove the cap
screws (B) that lock the
retainer ring onto the feed
nut. Remove both halves of
the Retainer Ring and slide
the feed nut off of the tool.
Step 3: Remove the Tool
Holder by loosening the
three set screws (C).
Step 4: Install the feed
nut handles (A) into the
Flange Facer feed nut.
Step 5: Install the
Flange Facer Feed Nut
(D) and replace the
Retainer Rings.
Step 6: Secure the Trip Ring (E) to the housing
with the cap screws provided.
BStep 7: Mount the Flange Facer Head
Assembly (F) onto the Drive Hub (G) with the
two (2) keys from the tool holder and two (2) set
screws provided.
With the conversion complete, refer to setup
and operating instructions for tool and cutter
positioning instructions.

Flange Fine Adjustment Alignment Kit
H&S offers this fine adjustment
flange facing alignment kit to
provide the most accurate setup
possible.
Insert the center shaft/locking
mechanism into the pipe.
Tighten the draw rod just
enough to stabilize the position.
The alignment fixture slides onto
the shaft until the four adjusting
screws contact the flange
surface. The fixture is locked in
place with the locking set screw.
There is a choice of dial
indicator mounts. The magnetic
base mounts by setting the unit
on the bracket and turning the
switch to "on". The arms are
adjusted to a position where
the dial indicator can be swung
a full 360 degrees without
interference.
The kit also includes threaded
extension rods and clamps for
mounting the dial indicator.
Tapped holes are provided on
the flat and side of the mounting
bracket into which a rod can be
located. The C-clamp can be
locked on that rod and another
rod affixed to the clamp to hold
the indicator. There are various
combinations to give you a
setup that will clear surrounding
obstructions.
