Water Tray Preparation
The sharpening system utilizes a wet grinding process to keep tools cool and prevent residue buildup. Before operation, fill the water tray located beneath the grinding wheel with clean water. Ensure the water level is sufficient to keep the lower portion of the grinding wheel submerged during operation.

Operating Instructions
Power On/Off and Speed Control
To power on the unit, locate the power switch. The system features a variable speed control knob, allowing you to adjust the rotational speed from 90 to 160 RPM for maximum precision. Turn the knob clockwise to increase speed and counter-clockwise to decrease it. To turn off the unit, set the power switch to the 'OFF' position.

Reverse Switch Function
The rotational direction of the grinding wheel can be reversed by pushing the power switch up or down. This feature is particularly useful for wood turners, woodworkers, and knife makers, allowing for sharpening in both directions depending on the tool and desired edge.
Sharpening Process
- Prepare the Tool: Ensure the tool to be sharpened is clean and free of debris.
- Select Jig/Guide: Use the appropriate grinding jig or short knife jig for your tool. The angle guide can assist in setting the correct sharpening angle.
- Position the Tool: Securely position the tool against the grinding wheel at the desired angle. The wet grinding action will keep the tool cool.
- Grind: Apply light, consistent pressure as you move the tool across the grinding wheel. Allow the wheel to do the work.
- Strop: Once the desired edge is achieved on the grinding wheel, move to the leather stropping wheel. Apply a small amount of honing compound to the stropping wheel for a polished, razor-sharp finish.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your sharpening system.
Cleaning the Water Tray
After each use, or periodically depending on frequency of use, empty and clean the water tray. This prevents the buildup of metal residue and ensures clean water for subsequent sharpening sessions. Rinse the tray thoroughly with clean water.
Grinding Wheel Care
The 1000 grit aluminum oxide grinding wheel is designed for durability. The resin process forms a protective layer, enhancing its lifespan. Periodically inspect the wheel for any signs of wear or damage. If the wheel becomes uneven or glazed, it may need to be dressed or replaced.
Leather Stropping Wheel Care
The leather stropping wheel requires occasional application of honing compound to maintain its effectiveness in polishing and finishing sharpened tools. Apply a small amount of compound evenly across the surface as needed.
General Cleaning
Wipe down the exterior of the unit with a damp cloth to remove any dust or debris. Do not use harsh chemicals or abrasive cleaners.
Troubleshooting
This section addresses common issues you might encounter with your sharpening system.
Unit Does Not Power On
- Check if the power cord is securely plugged into a working electrical outlet.
- Ensure the power switch is in the 'ON' or 'FORWARD'/'REVERSE' position.
- Verify that the circuit breaker has not tripped.
Grinding Wheel Not Rotating
- Confirm the unit is powered on and the motor is running.
- Check for any obstructions preventing the wheel from turning freely.
- If the motor runs but the wheel does not turn, there may be an issue with the drive mechanism; contact customer support.
Poor Sharpening Results
- Ensure the water tray is filled to keep the wheel and tool cool.
- Verify that the correct sharpening angle is being used for the tool. Utilize the angle guide.
- Check the grinding wheel for wear or glazing. It may need dressing or replacement.
- Ensure sufficient pressure is applied, but avoid excessive force which can slow the wheel.
- Apply honing compound to the leather stropping wheel for a finer edge.
