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.
