5. Operating Instructions

Before starting, ensure all safety precautions are followed and the grinder is properly set up.

1. Power On: Press the ON switch to start the grinder. Allow the wheels to reach full speed before beginning work.
2. Workpiece Placement: Hold the workpiece firmly and rest it on the adjustable tool rest. Slowly bring the workpiece into contact with the grinding wheel.
3. Grinding/Sharpening: Apply light, even pressure. Move the workpiece across the face of the wheel to ensure even wear and a consistent finish. Avoid applying excessive pressure, which can overheat the workpiece and damage the wheel.
4. Cooling: For metal workpieces, frequently dip them in water to prevent overheating and loss of temper.
5. Power Off: When finished, press the OFF switch. Wait for the wheels to come to a complete stop before leaving the machine or making adjustments.
