Power Supply Removal and Replacement
NOTES:
D
To avoid a loss in electrostatic performance, inspect
the gun body power supply cavity for dirt or mois-
ture. Clean the cavity with a clean, dry rag.
D
Do not expose the seal (27d) or gasket (27a) to
solvents as this will damage them.
1. Prepare the gun for service as instructed on
page 29.
2. Remove the barrel as instructed on page 35.
3. Grasp the power supply (27) with your hand. With
a gentle side-to-side motion, being careful not to
damage the power supply, pull the power supply
free from the gun body (29), then pull it straight
out. See Fig. 31.
4. Inspect the power supply for any physical damage.
Check the electrical resistance as instructed in
Test Power Supply Resistance, page 28. If nec-
essary, replace the power supply.
5. Before installing the power supply, inspect the seal
(27d) for any damage or swelling; replace the seal
if necessary. Make sure the gaskets and pads
(27a–27e) are in place.
6. Lubricate the o-ring (25a) and install the power
supply (27) in the gun body (29).
7. Assemble the gun as instructed on page 38.
Power Supply Adjustment
The kV switch, in the 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 between 45 and 80 kV.
To adjust the low voltage setting, use a small blade
end screw driver to turn the potentiometer (W). Turn it
clockwise
to increase the voltage or counterclockwise
to decrease it; fully clockwise is 80 kV, fully counter-
clockwise is 45 kV.
Apply a very light coat of lubricant to the o-ring (25a).
Do not expose the seal (27d) or gasket (27a) to solvents.
