Precautions
Threading
1. Take care when handling the blades.
-
To prevent accidents and injuries, take special care when handling blades such as dies, reamers, pipe cutters
and carbide cutters.
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 wear gloves when operating the machine.
-
Gloves may get caught in rotating parts or blades, resulting in accident or injury.
4. Do not leave the machine while it is still rotating.
-
Others may be injured.
5. 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 our sales department for an inspection and/or repair.
- Continuing to use the machine when damaged will likely lead to mechanical problems, accident or injury.
6. 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.
7. 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.
8. Be sure to check the starting position before threading.
- When threading, start with the carriage to the right of the red line on the front support bar (as viewed from the
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.
9. Use the pipe support when threading long pipes.
-
When threading long pipes, use a pipe support to prevent both vibration due to warping while the pipe
is rotating 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.
10. 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.
WARNING
Reaming
The reamer blade is very sharp; to prevent injury, avoid touching it with bare hands.
