Power Supply Removal and Replacement
NOTES:
DTo avoid a loss in electrostatic performance, inspect the gun handle power supply cavity for dirt or mois- ture. Clean the cavity with a clean, dry rag.
DDo not expose seal (B) or gasket (18a) to solvents as solvent will damage them.
1.Prepare the gun for service as instructed on page 22.
5.Lubricate the
6.Install the barrel on the handle as instructed on page 28.
7.Test the gun resistance as instructed on page 20.
2. Remove the barrel as instructed on page 24.
CAUTION
Be careful when handling the power cartridge to avoid damaging it.
3.Grasp the power supply (18) with your hand. With a gentle side to side motion, pull the power supply free from the gun handle (7), then pull it straight out. See Fig. 18.
4.Inspect the power supply for any physical damage. Check the power supply electrical resistance as instructed on page 21. If needed, replace the power supply.
Before installing the power supply, inspect the seal (18e) for any damage or swelling; replace it if necessary. Make sure the gaskets/pads
Power Supply Adjustment
The KV HI/LO switch, on the back of the gun manifold, enables you to switch between full voltage and a lower voltage output. The lower voltage is factory set at 60 kV, but can be adjusted.
The power supply may be equipped with either a potentiometer or a two position jumper pin. If you have the jumper pin style, place the pin in either the 45 kV or 60 kV position. If you have the potentiometer style, follow the directions below.
To adjust the low voltage setting, use a small blade end screw driver to turn the potentiometer (G), clock- wise to increase the voltage or counterclockwise to decrease the voltage; fully clockwise is 80 kV, fully counterclockwise is 45 kV.
