What procedure should be followed before using a bench grinder?

For safe and effective operation of a bench grinder, it is essential to prepare the equipment properly before use. The best practice is to dress the grinding wheel to ensure it has a sharp and even grinding surface, which helps in achieving optimal performance and reducing the risk of accidents.

Additionally, adjusting the tool rest with a maximum clearance of 1.6 mm (1/16") is important as it provides enough space to prevent the workpiece from snagging or binding in the wheel, while still allowing for accurate grinding. This clearance helps ensure that the workpiece can be manipulated easily without posing a safety hazard due to excessive proximity of the wheel.

By following these guidelines, an operator can ensure the bench grinder functions correctly while maximizing safety and effectiveness.
