Open the water valve and let the water drip at 80-100 drops a minute. Then turn on the switch. The machine is ready to be used. If Model W grinding wheel is chosen, the right side will be rough ground ,and the left side fine ground. When Model WV grinding wheel is chosen the result with be the same, but there is also a V-shaped slot to refine the lens. After the machine is used for a period of time, take the lower water can out and clean it in case the draining hole should be blocked. When the grinding wheel has been used for a period of time, grinding fatigue will appear (failing to grind in). In this case, use the oilstone stick to recondition the wheel.
