Using the Diamondblock

1. The surface needs to be clean and free from dirt. If required, clean it using an ordinary household paper cloth and water (a)
2. Take the water bottle and slightly spray a thin layer of water over the block (B), to moisten it. Observe! Nothing else than water is recommended to use on the block.
3. Place the part to be lapped or fnished on to the block. Hold the part between three fingers and exerting medium pressure on it, move it in the form of "8s", beginning with fairly small ones and then making them as large as possible, moving them from side to sode (C). It is advisable to slightly overlap across the edges of the block, except in the case of very thin or small-size parts. Frequently change the position of fingers so that the thumb, pressure of which is stronger, does not always press at the same place.
4. Check the progress of work. Add more water if necessary.
5. After lapping, clean the block only with water. Use compressed air with caution to dry the block.
6. After repeated use, preferential wear may develop on the surface (usually concave shape). To avoid this problem, the plate must be reconditioned with teh whetstone every 5 parts lapped. Apply manual pressure onto the LarsLap Diamond block during 3-4 minues as shown in the picture. (D)
