Warning! Never sharpen any type of blade or tool that is attached to any type of power equipment. Remove blade or tool and secure in a vise. Hold the GardenSharp® as shown in one hand with your fingers through the opening formed by the handle and the finger guard. Remember: The Sharpener moves while the tool being sharpened remains stationary.
Straddle the cutting edge of the tool being sharpened with the “v” shaped notch formed in the sharpener. Place the more visible carbide insert against the side of the tool that has a beveled edge. This should be the side that you want to sharpen. With the head of the GardenSharp® at about a 90 degree angle to the tool’s edge, press down lightly using thumb pressure to draw the GardenSharp® along the edge of the tool. Work in one direction only, not back and forth! You will feel the tungsten carbide sharpener removing metal from the tool. Several passes may be required before the tool’s beveled edge conforms to the proper angle of GardenSharp®.
Once that angle is achieved then two or three passes should be sufficient to bring the tool back to a sharp edge. REMEMBER: LIGHT PRESSURE IS SUFFICIENT. Heavy pressure might cause you to lose control of the sharpener and possibly cause injury. When sharpening lawnmower blades, always make sure your blade is properely balanced before installing. An unbalanced blade can lead to injury.
Occasionally, you may encounter a tool that is more awkward to sharpen from one side than the other. In such instances, you may wish to reverse the arrangement of the carbide sharpeners that are in your GardenSharp®. Refer to the diagram before attempting this.
To reverse the sharpeners, lay the GardenSharp® on its side with the screws up. Remove the screws and carefully separate the two halves of the handle as shown.
Simply switch the carbides in their slots. The larger carbide can be moved straight across to the other slot. The smaller carbide will have to be flipped over before switching slots. If the finger guard becomes disengaged during this operation, secure both ends of it in the slots provided before reassembly. CAUTION: DO NOT REASSEMBLE THE SHARPENER WITHOUT THE FINGER GUARD. SERIOUS INJURY MAY RESULT. Reassemble the two halves of the handle and secure with the three screws.
Warning! Improper use of this sharpener and/or failure to follow instructions can result in injuries. Correct use is the easy and safe way, so always use exactly as instructed. Keep your fingers inside the fingerguard as shown above and your thumb securely on the thumb-rest indentation, as shown above. Do not over tighten screws. The factory torque setting is about 5 inch pounds of pressure.Tighten them only until you feel increased resistance. If sharpener has any crack around the screw heads DO NOT USE IT. Either discard the sharpener or return it under the terms of the warranty. GardenSharp® is perfectly safe when used properly.
