Order and Procedure of Installation to the Pipes (MP0020-26)
1. After installation of the Manual Pipe Beveling
Machine, confirm whether minimum pipe
length projected is more than 140mm so that
the machine could be rotated along the pipe
and the work space is secured as more than
400mm.
The standard applications of this machine is
for 10”-26” pipes. If you would like to bevel
pipes with diameters of 6”-8”, you have to
install U-Plate provided separately after
removing the U-Block (List No. 15) installed in
the machine as standard.
2. Loosen the Inner Roller Adjustment Handle
(List No. 5) and Outer Roller Adjustment
Handle (List No. 11) to secure enough gap so
that the pipe could be inserted between Inner
Roller (List No. 3) and Outer Roller (List No.
17) easily.
3. Stick the MP0020-AD closely to the downside
of the pipe. Tighten it by turning the Inner
Roller Adjustment Handle (List No. 5)
approximately two (2) times from the start.
Turn the Outer Roller Adjustment Handle (List
No. 11) too approximately 1-1.5 times with
the same method. (At this time, be sure to
tighten the Inner Roller Adjustment Handle
first)
4. After you tighten the Outer Roller Adjustment
Handle, there should be a gap between the
surface of the outside diameter of the pipe
and lower portion of X-Plate (List No. 8), by
approximately 1-2mm.
In case the gap is not wide enough, adjust
the gap by tightening the Outer Roller
Adjustment Handle (List No. 11) a little bit
more and match the gap.

5. Turn the machine installed from the bottom
of the pipe clockwise so that it could be
positioned on the top of the pipe. (This
machine should be turned in clockwise
direction only. Never turn it anticlockwise.)
6. Turn the Chamfering Value Adjustment
Handle (Chamfer-Mill List No. 16) of the
Chamfer-Mill and set the beveling value to
be below zero (0) level. After that, install the
machine between the End Caps (List No. 7)
on both sides and match the angle. Tighten
4 units of M8x20 hexagonal bolts (Chamfer-
Mill List No. 27). (At this time, if the
beveling value is not set at under zero (0)
level, it may cause damages on the machine
and installation could be difficult.)
7. Insert the two Operational Handles (List No.
19) on both sides to the Outer Roller Shaft.
(List No. 16)
8. When inserting the left-hand side
Operational Handle, if it is difficult to insert
the Handle because the position of the
motor is not appropriate, loosen the Locking
Bolt (Chamfer-Mill List No. 13), adjust the
position of the Handle and then tighten the
Locking Bolt again.

9. After wearing the protective kit, turn on the switch of the motor first and then adjust the
intended beveling value by turning the Beveling Value Adjustment Handle (Chamfer-Mill
List No. 16) (Actual beveling work is started from this point on at a standstill state). Start
the beveling work by turning the Operational Handles clockwise with your hands.
10. The speed of the rotation should be different according to the beveling quantity, materials
and state of the insert tips. Therefore, the workers should adjust the speed of the rotation
appropriately.
11. After the beveling work is finished, turn off the switch of the motor and set the beveling
value at below zero (0) level for safety and beveling work next time.

How to Change U-Plate for 6” ~ 8”
1. At the state Cover (List No. 18) is separated from the Support Block, disassemble the 4
units of Wrench Bolt (Allen Screw) (List No. 15-1) fixing the Support Block (List No. 12) and
U-Block (List No. 15). Separate the U-Block (list No. 15) and the Outer Roller Shaft (list No.
16) by disassembling 2 Hexagonal Bolt (List No. 15-2). After that, assemble the U-Plate with
the Hexagonal Bolt (M10x30) provided instead of the U-Block.
At this time, the direction of the Outer Roller Shaft (List No. 16) and the groove on the
shaft should be facing appropriately so that the Operational Handle (List No. 19) could be
easily inserted on the shaft and move easily to do the beveling work.
2. The Hexagonal Bolt (M10x30) for fixing the U-Plate and Outer Roller Shaft should be
tightened completely and strongly.
12. Turn the whole machine down so that the machine could be positioned below the pipe for
easy disassembly.
13. Disassemble the two Operational Handles on both sides first. Disassemble the Outer Roller
Adjustment Handle (List No. 11) first and then disassemble the Inner Roller Adjustment
Handle (List No. 5) and remove the whole machine from the pipe.
14. In case the beveling work is needed continuously, you can attach the whole machine to
the pipes without disassembling the Chamfer-Mill from the machine. When needed, you can
disassemble the whole machine in an inverse order of the assembly and do the work again.

3. Assemble the U-Plate and
Support Block (list No. 12) and
then assemble the Cover (list No.
18) with the Wrench Bolt (Allen
Screw) (M5x15) provided.
4. Disassemble and remove Inner
Roller Handle (List No. 5) and
Outer Roller Handle (List No. 11)
and assemble Hexagonal
Adapter (17mmx15) provided
instead using Washer (Φ12x1.6t)
and Wrench Bolt (M4x8)
provided.

Differences of Chamfering Quantity as per the Installation
Application of Plate Beveling and Outside Diameter Beveling of Short Pipes
1. If you purchase MP0020-26 model, all the parts of List No. 28, 29 of Chamfer-Mill are
included as standard items and you can do the plate beveling manually too.
2. If you follow the instructions explained in “How to chamfer Outside Diameters of Pipes” in
the User’s Manual of Chamfer-Mill, you can do the pipe beveling of outside diameters of
short pipes with length of more than 6 inches manually.
3. In order to convert into the Manual Plate Beveler, disassemble the End Cap assembled with
the Y-Plate (List No. 1) and X-Plate (List-No. 8) and utilize it as Chamfer-Mill End Cap (List
No. 26) by assembling it with the V-Block Plate (List No. 28, 30).
The actual chamfering value could be different according to the changes of the gap (1-2 mm)
between the surface of the workpiece and the lower portion of X-Plate explained in item 4 of
“Order and Procedure of Installation to the Pipe”.
That is to say, even if you set the value by Beveling Value Adjustment Handle to be the same,
the result of actual beveling value will be different by the 1mm difference of the height of X-
Plate between 1mm gap case and 2mm gap case of the X-Plate. Moreover, even in cases of
the gaps to be the same 1mm, according to the beveling angle, the beveling value will be
different.
(Please refer to item 2 of Chamfering Depth Adjustment” of the User’s Manual of Chamfer-
Mill.)
Therefore, it is desirable to make the gap under the lower portion of the X-Plate to be
constant at the time of installation.
5. The Hexagonal Adapter (17mmx15) assembled in the above item 4 explanation could be
tightened and loosened by the Flexible Ratchet Wrench (17mm) provided.
6. Do the work the same as the explanations in item 3 of “Order and Procedure of Installation
to the Pipes”.
