• Threading work
A
WARNING
CD
Take care when handling blades and other sharp objects.
·To prevent accidents and injury, take special care when handling blades and other sharp objects such as the dies,
reamer, pipe cutter and carbide cutter, etc.
@ Do not place your hands or face close to rotating parts while the machine is operating.
· Inserting your hands into rotating parts and dies will result in accidents and injury.
®Do not perform the next operation until the machine has stopped rotating completely.
·
· Rotation does not come to a complete standstill when you tum the switch OFF.
Before starting the next job, check that rotating parts have stopped. Failure to do so may result in accidents and injury.
@
Do not leave the machine while it is still rotating
·Others may be injured.
®
If the mac!J.ine is accidentally dropped or hit, check carefully for damage such as cracks, broken parts, or
deformation.
· If any abnormalities are detected, ask your sales agent or our sales office for inspection and repair. Continuing to use
the machine in such a state may result in malfunction, accidents or injury.
®
Do not touch the dies just after threading
· The dies will be very hot just after completing threading. To avoid bums and other injuries, avoid touching them until
they have cooled down.
(j)
Die head and dies.
· Use the die head and dies that correspond to the diameter of the pipe to be threaded.
· Attach the die head correctly to the Carriage.
·Before starting threading, set the die head to the threading position, tum the switch ON, and make sure the threading oil
flows correctly from the die head and that the oil flows onto the dies. Also, make sure there is sufficient oil in the tank
to cover the strainer completely. This will prevent not only incorrect threading of the pipe, but also malfunction of the
machine, accidents and injury.
®
Make sure you start threading from the correct position.
®Use a pipe support when threading long pipes.
· When threading long pipes, use the pipe support to prevent vibration from warping while the pipe is rotating. The
support will also prevent the machine from becoming unstable under the weight of the material.
· Failure to use the pipe support may not only result in imperfect threads and malfunction of the machine, but may even
lead to accidents and injury.
®
Be sure to attach accessories according to the Operation Manual.
·If accessories and attachments are not fitted correctly, such parts may drop off during operation or the unit may fall
over resulting in accident and injury.
