Fasten pedestal and bench grinders on a solid surface securely. Ensure all the guards are in place and secure before using a grinder. Adjust tool rests to within 3 mm (1/8 in.) of wheels. Never adjust rests while wheels are moving. Work rest height should be on horizontal centre line of the machine spindle. Maintain 6 mm (1/4 in.) wheel exposure with a tongue guard or a movable guard. Check that wheels have blotters on each side. Check the wheel fits properly to the spindle when mounting. If it is loose, get another wheel. Tighten the nuts before you turn the grinder on. Before you plug in the grinder, manually spin the wheel to make sure it is spinning freely. Make sure the cables are not damaged and in good condition. Keep the cables out of the work area. Wear proper personal protective equipment: eye, ear and face protection, metatarsal safety boots, where required, respiratory protection may be required, depending on the work. Wear gloves only where necessary and if there is no risk of entanglement. Stand to one side of the grinder until the wheel reaches operating speed. Bring work into contact with the grinding wheel slowly and smoothly, without bumping. Apply gradual pressure to allow the wheel to warm up evenly. Use only the pressure required to complete a job. Move the work back and forth across the face of the wheel. This movement prevents grooves from forming. Wheels are made only for grinding certain items. Do not grind rough forgings on a small precision grinding wheel. is that enough
