Install the electrostatic cable on the gun.NOTE: The end of the cable acts as a piston in the insulating tube,pushing the dielectric grease around the resistor and spring, and aroundthe exterior of the tube. This totally covers the high-voltage contactpoints inside the gun with dielectric grease.6. Tighten the cable connecting nut.See Figure 7-4. Use this procedure to install a new resistor only, andcontinue to use the existing electrostatic cable.1. Disassemble the AN-8 Plus gun. Refer to Disassembling the Gun inthis section.2. Clean the old dielectric grease from the high-voltage bore with aclean cloth and a round brush. Clean as much grease out of the boreas possible.CAUTION: Do not handle the resistor with your bare hands.Salts and oils from your skin can conduct electricity and cancause arcing along the resistor. Arcing can destroy theextension and the resistor. Handle the resistor using a piece ofplastic or a clean, dry cloth.3. Install the resistor (2), spring end first, into the insulating tube (4).4. Install the greased insulating tube, resistor end (6) first, into thehigh-voltage bore. (The end of the insulating tube containing thedielectric grease (3) should go into the bore last.)5. Assemble the gun. Refer to Assembling the AN-8 Plus Gun in thissection.6. Install the electrostatic cable on the gun.NOTE: The end of the cable acts as a piston in the insulating tube,pushing the dielectric grease around the resistor and spring (5), andaround the exterior of the tube. This totally covers the high-voltagecontact points inside the gun with dielectric grease.7. Tighten the cable connecting nut.4. Replacing the ExtensionResistor Service Kit andCable (contd)5.
