If the front groove located close to the
lens, the counterclockwise rotation regulating knob (as shown in figure
3-3-26). Use method 3, automatic grooving machine tool (1): NG-5 automatic
slotting machine. (2) after operation steps: lens slot type setting, slot
according to the following steps. The depth scale shall be transferred to the
"0" position, the two switch is in the "OFF" position. The
accessory water feeder, water sufficient wetting cooling sponge. The clamp as
shown in the direction of the lens, lowering the head to the operating
position. The opening the guide arm, lens falls two nylon wheel, cutting wheel.

slot, and then close the lens switch off cutting wheel switch, raised his head.
And if the hard materials such as glass lens slot is deep, the first half of
the groove depth setting of the slot, then the depth of groove depth settings
can be required. 4, note (1) in a small drainage tube fixed slotting machine
cutting wheel in front, also formulated with a plug on the imitation of
accidental spray light, often need to pull the plug, to prevent excessive water
so that the bearing corrosion. (2) the daily out sponge clean, the use of the
former should inject water fully soaked sponge sponge, when used to replace.
(3) before use should be to the rotating shaft parts of lubricating oil, and
keep clean. (4) to replace the cutting wheel, should first disconnect the power
plug, and then in the pumping hole in the insert a thin rod, and then Phillips
