• Inspect workholders for accumulated coating
materials, removing such accumulations.
• Check that atomizer assembly is clean and
undamaged.
• Straighten the applicator electrode if necessary.
> If the shut-down time is to be short, the
lines may not require flushing, depending
on the type of coating material used. If the
solids in the material settle slowly, the
lines will not need to be flushed as soon
after shut-down as with fast settling sol-
ids. The fluid/solvent being used and the
length of time that the lines will be shut-
down will determine the need for flushing.
Metallic paint and primer will require flush-
ing sooner than some other types of coat-
ing materials.

> If the coating material is fast settling and
if the lines are not flushed soon enough, the
applicator’s fluid passages as well as the
lines may become clogged and cause ex-
cessive down-time and/or service and re-
pair.

2. Turn the fluid/solvent supply OFF.
3. Turn the atomizing air and fan air OFF.
4. Turn piston air OFF.
5. Wipe the applicator, cable, and hoses with
a rag and a suitable cleaning solvent.
6. Flush the lines and allow the solvent to
remain in the lines unpressured. (See
“Flushing Procedures” in the “Maintenance”
section of this manual.)

• Check the entire system for damage, leaks,
and paint accumulation.
• Clean the atomizer assembly.
• Clean the fluid filter, if used.
• Turn the control unit power ON. The applica-
tor’s red transformer light should light when
triggered.
• Run a current/voltage output test.

1. Turn the fluid/solvent supply OFF.
2. Turn high voltage on at applicator.
3. Slowly approach the applicator electrode to
any grounded object and make contact.
4. Monitor the current output reading on the
power supply meter. As applicator approaches,
ground current should increase near 120 mA.
Overload current should “trip”, shutting off high
voltage. Overload indication should come on.
5. Release the trigger and turn the power supply
power OFF.
If the control unit does not trip, DO NOT DO NOT DO NOT DO NOT DO NOT use the
applicator until the problem has been corrected.
