PRECAUTIONS WHEN USING 8991
Using the pipe cutter
WARNING
6.If you accidentally drop or hit the machine, carefully check for damage, cracks,
deformities or any abnormalities.
- If any abnormalities are found, ask your distributor or WHEELER-REX 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 front support bar (as viewed from the
working position). If the carriage is not in the correct starting position, the die head will collide against the main
unit while threading, causing mechanical problems, accident or injury.
10.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.
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.
12 .Precautions when using the machine with an oil tray.
- If you are going to work with the machine placed in an oil tray, be sure to put the machine on a table and make sure
it is not immersed in oil, otherwise the oil might be sucked in resulting in damage to the motor.
CAUTION
1.When cutting pipes, turn the cutter handle no faster than ½ a rotation for each
rotation of the pipe.
- If the cutter handle is turned too quickly when engaging the pipe, it can distort the shape of the pipe and may not
make a proper thread.
2 .Do not leave the machine unattended while it is still rotating.
- Others may be injured.
WARNING
1.Changing parts with blades, sharp edges, etc.
- To prevent accidents and injury, take special care when handling or changing any parts with sharp edges such as
dies, reamers, pipe cutters and carbide cutters.
- Be sure to attach accessories according to the operation manual. Make sure you use only genuine WHEELER-REX
accessories. Using any other type can lead to accident and injury, as well as damaging the machine itself.
- Avoid attaching accessories incorrectly as doing so may cause the machine to topple over, resulting in accident or injury.
2 .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 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; as a result, problems with the machine, accidents or injuries may occur.
3.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.
4 .Do not wear gloves when operating the machine.
- Gloves may get caught in rotating parts or blades etc., resulting in a serious accident or injury.
