2. Connect the low voltage cable to a control unit
and a cable plug assembly (refer to Figure 16).
3. Connect the low voltage cable and the plug
assembly to the hook/transformer. This can be
done without the handle on a workbench or with
the hook/transformer, low voltage cable, and plug
assembly installed into a handle. DO NOT perform
this test with the barrel attached to the hook/
transformer.
4. On the control unit, turn the high voltage
adjustment knob fully counter-clockwise.
5. Make sure that the on/off switch of the hook/
transformer is in the "ON" position, if the unit has
this option (refer to Figure 17).
6. Turn the control unit on and adjust the voltage
knob clockwise to increase the voltage to the
hook/transformer.
7. Watch the red lens at the rear of the hook/
transformer. As the voltage is increased, the LED
behind the lens will increase in intensity. Once the
voltage control knob is turned fully clockwise, the
LED should be at it's highest intensity.
