3/8-inch Allen wrench.

DISASSEMBLY PROCEDURES
Prior to disassembly, verify the following:
• The atomizer disk, valves and regulator have
been flushed with solvent and purged dry with
air.
• The disk has stopped rotating.
• The air supply to the trigger valves and
regulator have been turned off.
• The fluid and solvent supply have been turned
off and the pressure has been relieved.
• The high voltage has been turned off and the
motor housing grounded.
4. Next remove screws holding the fluid tube as-
sembly.
• Inspect the disk edge and face. If damage
exists, DO NOT USE. Return it to
Ransburg for evaluation.
• Check the fluid feed tube to make sure it is not
rubbing the disk.
Weekly Maintenance
Follow the normal daily maintenance schedule,
then:
• Monitor rotational speed at the control and
verify it is within 5% of target speed.
• Monitor high voltage output indicated on the
power supply display. Verify with high voltage
probe and meter.
• Remove fairing and clean all internal
components: valves, regulators, and tubing.
Check tubing for evidence of pin-holes, kinks,
and abrasions.
• If the muffler needs to cleaned (item is to be
solvent cleaned) remove it from the motor.
Clean and dry the muffler before reinstalling it.
• Check fluid flows by removing the disk and
manually triggering the paint valve. Measure
the amount of fluid in a graduated beaker over
a specific time to determine flow rate.
• Clean and inspect the disk face. Look for wear,
which can cause poor transfer efficiency and
excessive paint wrap on the atomizer fairing.
Disk removal, cleaning and inspection may be
done more or less frequently, depending upon
use.
