Precautions
Threading

WARNING

1. Take care when handling the blades.

- To prevent accidents and injuries, take special care when handling blades such as Dies, Reamer, Pipe cutter
and Carbide cutter.

2. Do not put your hands or face near rotating parts when the machine is in use.
- You could get caught in rotating parts or hit by scrap, resulting in accident or injury.

3. Do not perform the next job until rotation stops completely.

- When you turn the switch off, rotation does not stop immediately. Perform the next job only after checking
that the machine has come to a complete stop. Failure to do so may result in accident or injury.

4. Do not wear gloves when operating the machine.

- Gloves may get caught in rotating parts or blades, resulting in accident or injury.

5. Do not leave the machine while it is still rotating.
- Others may be injured.

6. If you accidentally drop or hit the machine, carefully check for damage, cracks, deformities
or any abnormalities.
- If abnormalities are found, ask your distributor or dealer for an inspection and/or repair.
- Continuing to use the machine when damaged will likely lead to mechanical problems, accident or injury.

7. Do not touch the Dies or scrap just after threading.

- The Dies and scrap can become very hot just after threading; touching them could burn or injure you.

8. Die-head and Dies.

- Use the Die-head and Dies that are appropriate for the type and diameter of pipe to be processed.
- When threading stainless steel pipes use pipes with a wall thickness equivalent to Schedule 40 or more.
- Make sure the Die-head is mounted correctly on the Carriage. Be careful not to get your fingers caught.
- Before you start threading, set the Die-head in the threading position, switch ON, and check that the oil is
flowing correctly over the Dies. Failing to do so could result in an imperfect thread, damage to the machine,
accident or injury.

9. Be sure to check the starting position before threading.

- When threading, start with the Carriage to the right of the red line on the Carrige support bar A (as viewed fromthe working position).
If the Carriage is not in the correct starting position, the Die-head will bang into the main unit while threading,causing mechanical problems, accident or injury.

10. Use a pipe support when threading long pipes.

- When threading long pipes, use a pipe support to prevent both vibration due to warping while the pipe isrotating and instability of the machine due to the weight of the workpiece.
If a pipe support is not used, threading cannot be performed correctly and problems with the machine,
accident or injury may occur.

11. Be sure to attach accessories according to the Operation Manual.

- Attaching accessories incorrectly may cause the machine to topple over resulting in accident or injury.

ReamingWARNINGThe Reamer blade is very sharp; to prevent injury, avoid touching it with bare hands.

(Fig. 23)

CutterhandleCutterhandleHammerchuck

Fig. 23*Note: If the Cutter handle is turned too quickly, it will affect theshape and finish of the thread.

CAUTIONBe sure to position the Cutter correctly before the pipe starts
rotating.
If it is not in the correct position it could damage the pipe or themachine.

Special precautions when you cut a pipe withanother cutter
We strongly recommend that only the Cutter attached to the machine
be used to cut pipes.
If another cutter is used, ensure that the pipe end is at right angles
to the axis of the pipe. (Fig. 24-A)
If the pipe is not square on, as in Fig. 24-B and C, threads may be
defective. B and C may be the result of the following:(Fig. 24-B)- The bearing or chucking of the Cutter is unstable.
- When a grinder is used with excessive force (especially in thecase of large diameter pipes.)- When the pipe is engaged at an angle when cutting.

CAUTION

If the end of the pipe is slanted (Fig. 24-B) or has steps in it(Fig. 24-C), it is not only impossible to make a perfect thread,but may even result in damage to the machine, accident or
injury.

Precautions when threading

Care when the Dies come into contact with the pipe (Fig. 25)
Engage the cutting edge of the Dies very lightly with the end of
the pipe.
Bringing the Dies too forcefully into contact with the pipe will
result in damage to the Dies and shorten their working life.
Once the Dies engage the end of the pipe, apply light pressure
to the Carriage handle in a clockwise direction and then gradua-lly increase the pressure.
As the Dies cut into the pipe, it is no longer necessary to applypressure to the Carriage handle as the Carriage will move on its
own.

Release- Lower the Reamer arm and set it in position on the Carriage, thenpush the Reamer shaft toward the pipe. (Fig. 26-1)

Fig. 26* Note: Reaming is possible without pushing the shaft when apipe is chucked long enough from the Chuck.
Turn
right

- Lock the Reamer in position by turning the Reamer shaft anti
-clockwise. (Fig. 26-2）- Turn the machine on to start the pipe rotating. Then turn the
Carriage handle to the right to move the Reamer forward to engage
the pipe.
Allow the pipe to rotate at least ½ a turn, then remove the Reamer
from the pipe.
That completes the reaming process. (Fig. 27)

MoveforwardFig. 27

CAUTION- Do not use excessive force when pressing the Reamer against the pipe as this may scratch the pipe or even damage
the machine.
- The Reamer blade is extremely sharp. NEVER touch it with your bare hands, as you could be seriously injured.

Points to watch when threading
The FP / FR50A Series comes with the Manual, NV-auto, or Uni-auto Die-head (½ - 2") and 2 sets of Dies (½ - ¾")(1 - 2")
as standard accessories.
Check that the Die-head and Dies you are using are suitable for the pipe you are working on.

Operation Guide (Adjusting the oil flow / Measuring threads with a gauge)
14. Adjusting the oil flow

CAUTION

Do not adjust the oil flow while the machine is rotating.
You can adjust the oil flow from the Die-head.
- With the Die-head in threading mode, remove the Oil pan and checkthe discharge of the oil.
- Turn the Relief valve to adjust to the most suitable amount of oil
needed. (Fig. 41)- Rotating the valve clockwise decreases the oil flow; turning in the
opposite direction increases it.
Oil flow should not be adjusted while the machine is running.

Relief valve
Fig. 41*Note: Depending on the load when threading, the amount of oil
will vary according to the speed the machine rotates.

15. Measuring threads with a gauge

WARNING
Threads may be affected by the condition of the Dies (blades), Cutting oil etc., so be sure to use a Thread gauge
to check the thread. This is especially important after you have changed a set of the Dies.

Confirming the thread diameter (Figs. 42 - 43)- Use a thread gauge to confirm the diameter is as it should be.

Thread gauge

Other pipe thread gauges

Fig. 42

Confirming the number of threads- Confirm whether the thread length is as it should be according
to the number of threads as shown in Fig. 44.

CAUTION

Choose an appropriate method for checking the threads on
joints and other connections, such as using sealants, washing
the joint, checking the torque etc.

(Measuring threads with a Gauge)

Unacceptable threads- Irregular shaped threads (Fig. 45-1)
Recognising irregular shaped threads
a.Visually inspect the thread after wiping off any oil or dirt witha rag; you will find a wave-like formation.
b.Gently check the surface of the thread with your fingers, feel-ing for any irregularity.
c.Check if bits of scrap are produced when cutting.
- The diameter of the thread is too small or too large (Fig. 45-2)
Check with a Thread gauge.
- Distorted threads (in the case of Manual Die-head) (Fig. 45- 3)
When cutting threads that are longer than the width of the Dies,
you can gradually open up the Eccentric handle; but then if you
leave the Eccentric handle in the same position and cut a thread
longer than the width of the Dies, the taper will remain the same
width as the Die and the rest of the thread will be straight.
- Threads are too thin (Fig. 45-4)
