Einhell TC-WG 200 Wet Bench Grinder User Manual

Product Overview

The Einhell wet sander TC-WG 200 is designed for precise sharpening of tools without causing damage to the workpiece. Its wet grinding system continuously supplies water to the cutting edge, effectively preventing frictional heat buildup and annealing of the disc. This versatile device offers flexibility for grinding a wide range of tools. It features a corrosion-free water tank for cooling and includes an angle gauge for precise sanding angle adjustments. The sanding wheel can be prepared using the included grindstone, and the workpiece can be polished with stripping paste. For stability, the unit is equipped with four rubber feet that dampen vibrations and ensure secure placement. The package includes a slow-running, fine-grained wet sanding wheel and a leather sanding wheel for deburring.

5. Power Connection: Connect the power cord to a suitable 125 Volt AC power outlet. Ensure the power switch is in the "OFF" position before plugging in.

Operating Instructions

The Einhell TC-WG 200 is designed for efficient and precise sharpening. Follow these steps for optimal results.

1. Prepare the Grinding Wheel: Before initial use or if the grinding wheel becomes uneven, use the included grindstone to dress and prepare its surface. This ensures a consistent and effective grinding action.
2. Set the Angle: Use the angle gauge to determine and set the correct grinding angle for your tool. Adjust the tool rest accordingly to maintain this angle during grinding.
   

   Figure 6: The angle gauge assists in precise angle setting for various tools.

3. Start the Grinder: Turn on the power switch. The 125 W motor will accelerate the wet sanding wheel to approximately 110 RPM. This slow speed is ideal for fine sanding and prevents overheating.

5. Honing and Polishing: After grinding, switch to the leather honing wheel to remove any burrs and achieve a finer, polished edge. For an even better finish, apply stripping paste to the leather wheel before honing.
6. Finishing: Once the desired sharpness and finish are achieved, turn off the grinder and carefully remove the tool.
