Select a compatible wheel
The wheel must suit the machine, work material and operation. Check dimensions, shape, mounting system and the manufacturer’s marked maximum speed. The machine must not exceed the speed permitted for the wheel.
Not every wheel accepts side loading or is suitable for every metal. Physical fit does not demonstrate compatibility. If identification is missing or its origin or condition is uncertain, resolve that uncertainty before installation rather than relying on appearance alone.
Condition and mounting
Impact, unsuitable storage and incorrect tightening can damage a bonded wheel. Remove damaged or suspect wheels from use. Inspection and any tests applicable to that wheel type require trained personnel; a ring test does not replace all other checks.
Installation and replacement require the equipment instructions and Lockout/Tagout (LOTO) where applicable. Do not improvise adaptors, alter the mounting hole or attempt to overcome abnormal vibration by pressing harder on the workpiece. Different wheel constructions need their own handling precautions.
Guards, support and ejected material
Keep Machine guards complete and secure. The work rest and adjustable protective parts need review as the wheel wears, using the clearances specified for that machine. Never adjust them while the wheel is moving.
The workpiece must be supported without bringing fingers into danger or allowing it to become jammed. Small parts need a suitable holding device or a different process. A shield mounted on the grinder does not replace the Eye and face protection selected for the flying-particle hazard.
Surroundings and warning signs
Sparks and hot material require control of nearby combustibles and protection for other people. Assess dust from the particular abrasive and work material, including Ventilation and local exhaust ventilation where needed, as well as noise exposure.
Avoid loose clothing, unsecured hair and anything liable to catch. Glove selection must consider entanglement as well as cuts. Cracking, vibration, unusual noise or damaged protection requires stopping use and obtaining competent review before work continues. Do not regard a previously uneventful operation as proof that these defects are harmless.
