1
Hold the push button and slide the guide bur straight in as
shown in the illustration. Then rotate it left and right.
• Do not bend or deform the electrode.
• Always use the guide bur and make sure it will not come out. If the guide bur is not properly fix in place, the internal contact could be bent, and then the instru-
ment might not be able to make accurate measurements or else it might malfunction.
• Do not run the motor with the guide bur inserted; this could damage the instrument.
