Precautions for Use

To prevent accidents and ensure safe use, please be sure to read the safety precautions in advance, the information listed on the inspection form, and the operating instructions for the machine you are using.

1. Precautions Regarding the Work Environment, Clothing, and Protective Equipment

   • Workers must wear protective equipment such as safety glasses, dust masks, safety shoes, and hard hats.
   • Sparks may be generated from the wheel during use. Do not use it in environments where there is a risk of fire or explosion.

2. Precautions Before Use

   • When using the wet method, take great care to ensure that the coolant supply does not run out.
   • Please do not perform any additional machining that alters the shape of the wheel. If a change in shape is necessary, please consult with us.
   • Do not use the wheel if its shape and dimensions do not conform to the grinding machine's specified dimensions (wheel outer diameter, thickness, and bore diameter).
   • If the wheel base is made of iron, remove any rust inhibitor that has been applied to it.
   • If the wheel base is made of a ceramic material, gently tap the side of the wheel with a wooden hammer before installation to perform a sound test.
   • Wheels are designed for specific applications, such as grinding the outer circumference or the side surface. Please verify that the wheel is suitable for your intended use.

3. Precautions for Installation

   • Be sure to turn the power "OFF" before installing or removing a wheel from the grinder.
   • If the wheel hub is made of a ceramic material, please place the cushioning material (such as the paper provided with the wheel) between both sides of the wheel to prevent cracks or fractures from occurring during flange installation.
   • When fitting the wheel onto the flange, do not force it in by tapping it with a hammer or similar.
   • If the wheel base is made of a ceramic material, install the wheel with the SUN mark positioned directly upward and ensure that the wheel is perpendicular to the spindle.
   • Be sure to tighten the mounting screws for flanges and other components securely with uniform torque at each diagonal position to prevent loosening.

4. Precautions for Grinding Operations

   • Never let your hands or any part of your body come into contact with a spinning wheel. Also, in the case of dry grinding, the wheel may be very hot after grinding, so be careful not to let your hands or any part of your body touch it.
   • Never use the wheel beyond the maximum operating peripheral speed specified on the wheel inspection sheet or the permissible rotational speed of the grinding machine spindle.
   • If you hear any unusual noises or feel any unusual vibrations, immediately move the wheel away from the workpiece and shut down the machine.
   • Before starting work, perform a 1- to 3-minute no-load test run to verify that the wheel is rotating in the correct direction and to check for any wobble or other issues.
   • When machining using the wet method, make sure that the coolant is adequately covering the grinding area.
   • When the wheel comes into contact with the workpiece, be careful not to cut too deeply. Also, do not use the tool continuously under overload conditions.
   • When using the dry method, be careful not to let the wheels seize up.

5. Precautions for Storage and Handling

   • If you remove the wheels for storage after use, store them in a dry place where there is no risk of them falling or being subjected to impact.
   • If the wheel base is made of iron, apply a rust inhibitor before storing it.
