MMA-303 Direct/Indirect Charge - Maintenance
LN-9269-11.3 90
Before Installing A New or Used Electrode
Into the High Voltage Ring
Replace the dielectric grease in the area as
shown in “Replacing Dielectric Grease” figure.
A thin film is all that is required.
Replacing Dielectric Grease
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, elec-
trode tips will last 3-6 months. The electrostat-
ic field generated by these electrodes are very
important to maintain paint transfer efficiency,
pattern uniformity, and atomizer cleanliness.
Applications above 5,000-feet Sea Level:
When using the MMA-303 atomizer with indi-
rect charge above 5,000-feet sea level, it must
be used in conjunction with a 78842-00 in-line
resistor assembly and a 78809-00 ground re-
sistor assembly (see “Indirect Charge Sche-
matic for Use Above 5,000-Ft. Sea Level” fig-
ure).
