FF 424 FLANGE FACING SYSTEM
C. BEVELING MACHINE OPTION SET-UP
AND OPERATION INSTRUCTIONS
Extension Leg Selection
1. The FF 424 BEVELER uses one mandrel assem
bly with the addition of eight leg extension sets to
cover its entire operating range (3.780” to 12.82”
I. D.).
2. The mandrel itself has three permanently mounted
chuck legs which expand or contract to the inside
wall of the pipe with or without extension legs when
the draw bar nut is rotated.
3. To determine which extension leg set is required,
measure the work piece pipe I.D. (Refer to
the extension leg selection chart.)
Each extension leg will be stamped with its part
number for easy identification.
4. Select the required extension leg set. The exten
sion legs fasten to the permanently mounted chuck
legs with two captivated socket head cap screws
in each leg.
Mounting the Mandrel Assembly Into the
Pipe
NOTE: It is recommended to mount the mandrel
by itself and then install the machine onto the
mandrel to Insure proper squaring of machine
and avoid operator injury.
1. Insert the blade end of mandrel into the pipe. For
best results keep the end of the blades as close
to the pipe edge as practical. The maximum depth
of penetration into the pipe should be 3/4” (19mm)
from the tapered ends of the leg to the end of the
pipe. Be certain that there is adequate clearance
between the blades and the 1.0. tooling. This will
allow for a normal prep and still keep the beveling
head rigid.
2. Move the mandrel back and forth and up and down
while tightening the draw bar nut. The chuck legs
will automatically help center the machine.
Torque
the draw bar nut to 90 ft. lbs.
Important: Place mandrel shaft keyways in re-
lationship to locating keys in machine to select
air motor operating location.

D. Mounting Machine Assembly On Mandrel
1. Inspect the bore of the beveling head for dirt and
metal chips. Clean the bore with compressed air
or solvent as necessary.
2. Wipe the mandrel clean and apply a light coating
of oil.
3. Insert the machine body over the mandrel being
careful not to scrape the head bushing.
4. Align the keys in the machine with the keyway
slots in the mandrel. Push the machine forward
until the feed nut and threaded portion of mandrel
shaft meet.
5. Rotate feed handle assembly clockwise engag
ing feed nut and machine with mandrel.
6. Next, tighten the machine / mandrel locking set
screws located on either side of the machine
body using the provided hex key set. Tighten
both locking screws equally. Applytension in
order to pre-load the machine to the mast and
remove any play.
7. Connect a clean, dry 90 PSI air supply to machine.
It is recommended to use an ATM air treatment
module in the air line to filter the air and lubricate
the air motor.
NOTE: Use 90 PSI maximum air pressure.
Higher air pressure increases the loads and
stresses on the tool parts, sockets, and fasteners
and may result in breakage. Higher air pressure
also increases the sound level of the tool.
E. Form Tool Installation Procedure
Setting Up The Form Tools: (Refer to tool selec
tion chart.) Install the facing tool in beveling head.
All tool bits must be installed so the cutting edge
will contact the pipe when rotating in a clockwise
direction, as seen from rear of machine. The tool
bits are locked into place with the set screws ad-
jacent to the slot.
CAUTION: Do not allow tool to
come in with mandrel or dam-
age will
CAUTION: Disconnect the air
supply when ever changing or
adjusting the form tool.
