Ransburg RMA Indirect A11600 - Manual (Page 71)

If reading falls out of this range, disassemble
electrode assembly and check reading of resistor
only. If reading is in the acceptable range, discard
the electrode body (A11342-00) and replace with
a new one. Rebuild electrode assembly as follows:
apply a small amount of dielectric grease to each
end of the resistor, slide resistor into the electrode
body (A11342-00). Install the contact assembly
after the resistor. Finally, apply a small amount of
dielectric grease to contact area of plunger contact
assembly. Thread plunger contact assembly into
electrode body by hand until it stops. Hand tight
is good enough. Over-tightening will damage the
electrode body (see Figure 55).

Before Installing A New or Used
Electrode Into the High Voltage Ring
Replace the dielectric grease in the area as shown
in Figure 56. A thin film is all that is required.

Electrode Tip Inspection
Inspect the electrode tips weekly or sooner. If
a collision has occurred, immediate inspection
is required. The tip of the electrode should be
sharp and pointed. After time, the tip will wear.
If the tip is rounded or worn jagged it must be
replaced. Depending on use, electrode tips will
last 3-6 months. The electrostatic field generated
by these electrodes are very important to maintain
paint transfer efficiency, pattern uniformity, and
atomizer cleanliness.
