  • Page 7: Safety Rules & Cutting Precautions

    Safety Rules & Cutting Precautions SAFETY RULES Observe these safety rules to prevent injuries and accidents. (The illustrations may be partly different from the actual machine in detail.) a) Use roller tables on both front and rear sides of the machine when cutting long work.
  • Page 8 c) Use a water-soluble cutting fluid on this machine. Oil- based cutting fluids may emit smoke or catch fire, depending on the condition of their use (such as insufficient flow rate). When using an oil-based cutting fluid, strictly observe the precautions described in “Cutting Method”...
  • Page 9 Be sure to confirm that the area around the machine is cleared of people and obstacles every time before starting the machine or operation. g) Never start the saw blade unless it has been confirmed that the work is firmly clamped. If the work cannot be securely clamped with the vise, be sure to clamp it using jigs.
  • Page 10 Never operate the machine with the wheel cover, the saw blade cover, and other covers removed or opened. It is dangerous if your hands or clothing are caught in the running machine. Never take your eyes off the machine or lean on the machine during operation.
  • Page 11 Never try to adjust the wire brush on the saw blade or remove chips when the saw blade is running. It is dangerous if your hands or clothing are caught in the running saw blade. m) Stop the saw blade whenever cleaning the machine.
  • Page 12 o) Turn off the shop circuit breaker switch before servicing the machine. Then SERVICING post a sign to inform people that the machine is under maintenance. p) Never modify the machine's parts or electric circuits or change them with unauthorized parts or circuits. Doing so will cause machine problems and damage and disrupt the safety of the machine and the operator.
  • Page 13 DANGER and WARNING plates Keep the DANGER and WARNING plates well noticeable and never remove them. DANGER DANGER DANGER Do not step on the roller. DANGER Do not open cover Keep away Do not touch while from machine the blade machine is running.
  • Page 14 An appropriate saw blade also varies with the requirements of your job (such as cutting accuracy, cutting speed, and economy) even when the same work is to be cut. Consult AMADA about the selection of saw blades for specific jobs.
  • Page 15 Cutting method According to its material, the work may be cut wet (or with a cutting fluid), or dry (or without a cutting fluid). The materials to be cut wet or dry are listed in the table below. Wet cutting Use a water-soluble cutting fluid on this machine.
  • Page 16 Dry cutting The machine needs special measures for performing dry cutting. Consult AMADA. If dry cutting is performed without taking special measures, chips may accumulate in machine parts and may cause the operation or insulation failure of the machine. The machine also needs special measures for cutting carbon and other materials that produce and disperse explosive dust.
  • Page 17 Cutting flammable materials Chips of titanium or magnesium violently burn when they catch fire. Once these chips burn, the resultant fire may explosively propagate through surrounding chips. When an oil-based cutting fluid is used on the machine, it may also be ignited and spread the fire. When cutting such flammable materials, be sure to clean the machine of accumulated chips at the start and end of every operation.

  • Page 19 Appendix 3: Cutting fluids suited for specific materials This table shows the general machinability of materials with different cutting fluids. Some materials may be cut better with an oil-based cutting fluid than a water-soluble cutting fluid.
