Figure 1
Figure 2
1) Unlock the screw of part A (See Figure 2)
2) Push out of the part B, then… (See Figure 2)
3) You can change the distance of the pearl clamp (See Figure 1)
4) After fit your pearl size then you can lock the screw again.
The operation procedures of using WTD 002 is equal to WTD 001.
This is a professional design which is ideal for drilling the longer pearl. Therefore, Auto-
matic adjustment of the pearl clamp is very important. You can see the different of the
pearl clamp distance which already shown on picture 1

OPERATION PROCEDURES
Step 1.
Figure 1
Step 2. Mount the Drilling Handle at the back of the drilling machine.
(See Figure 2)
Figure 2
Place and Mount the Transfer Pan onto the drilling machine by using the
Locking Screw. (See Figure 1)
Place the suitable pair of Clamping Heads on the Pearl Clamp to fit the
Pearls for drilling.
Install and mount the Ground Bit Insert # on the Drilling Chuck by use of
the Chuck Key.
Step 3.
Step 4.

Press the Mounting Handle slightly, push the Drilling Handle to the left end
side, adjust the Ground Bit Inserts (use of Chuck Key) at the center posi-
tion and make sure that the distance between two ends of Ground Bit
Inserts is about 1 mm. (See Figure 3)
Caution:
Please mention that this step must be done before operation, otherwise
two ends of Ground Bit Inserts will collide and damage when drilling.
Step 5.
Figure 3
Figure 4
Step 6. Open the Power Source Cover of the Driving Motor. Connect the input
power cables and adjust the suitable input voltage that adopted in local-
ized voltage standard by arranging the metal strips. (See Figure 4)

Figure 5
Figure 6
Note: The voltage selection methods are shown as Figure 5.
D1 and D2 are known as the input terminals.
Note: The worktable and the switch box shown in Figure 6 are not
provided. The layout and the dimensions of the worktable sur
face are shown in Appendix.
Close the Power Source Cover. Assembly the Main Body and the Driving
Motor on the worktable. (See Figure 6)
Step 7.

Step 8. Place the pearl between the two Clamping Heads. Clamp the pearl on the
Clamping Heads by stepped down the Stepping Pan. (See Figure 7)
Figure 7
Pull out the Drilling Handle to the Right end to ensure that the Ground Bit
Inserts are located away from the pearl.
Connect the power plug onto the power socket. *
Turn “ON” the power switch.
Push the Drilling Handle towards LEFT end slowly and start to drill the
pearl (See Figure 8).
