Daily (or at start of each shift)
• Verify that ALL solvent safety containers are
grounded!
• Check within 20-feet of the point of operation
(of the applicator) and remove or ground ALL
loose or ungrounded objects.
• Inspect workholders for accumulated coating
materials (and remove such accumulations).
• Check that atomizer assembly is clean and
undamaged.
• Check the applicator electrode for damage.
• Clean the fluid filter, if necessary.
• Turn the control unit power ON. Its green pilot
should light or Aviator will be audible.
• Run a voltage output test.
Applicator High Voltage Output
Test (Cascade/Classic)
Use high voltage probe assembly (76652-01).
1. Set the meter dial to the kV scale. Plug the
high voltage probe into the side of the meter.
2. Attach the ground clamp to a proven earth
ground.

† Injury to personnel and damage to equip-
ment is probable if the ground clip is NOT
ATTACHED. This step MUST be accom-
plished before voltage is applied.
3. Make sure all grounded objects are at least
2-feet away.

4. Line up the hole in the test probe and the
electrode. Slide the test probe straight over the
electrode wire of the applicator.
5. Holding the metal portion of the high voltage
probe in your hand, trigger the applicator so voltage
exists at the electrode.

!
† To provide proper equipment to operator
ground, the conductive handle of the probe
MUST be held in the bare hand of the op-
erator. To avoid a shock hazard, the meter
should NEVER be disconnected from the
probe during high voltage contact.
6. Read the voltage displayed on the meter.
7. Turn the voltage to the applicator OFF, and
pull the test probe straight off the electrode.
Shutdown (or at end of shift)
1. Turn the control unit/power supply power OFF.
2. Turn the paint supply OFF.
3. Turn the shaping air supply OFF.
4. Wipe the applicator, cable, and hoses with a
rag and a suitable cleaning solvent.
5. Flush the fluid lines and applicator. Then bleed
the fluid pressure to zero, and allow the solvent
to remain in the lines (see "Flushing Procedures"
in this section).
6. Set the trigger stop lever.
