Turbodisk 2 - Maintenance
23
• To prevent solvent penetration beyond the slinger, a
minimal air pressure of 5 to 10 psi should be applied
to the motor in order to maintain a positive pressure.
The motor should be run at operating speed for
several minutes after cleaning to keep any solvent
that has accumulated at the seals from penetrating
into the motor housing.
• 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.
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.

Removal
1. Remove disk mounting nut by holding the
rotator shaft above the disk with a 7/16" open
end wrench and unscrewing the mounting
nut with a 3/8-inch wrench.
2. Install the Ransburg 19850-00 disk puller into
disk to remove it.
3. Unlatch the four fairing draw latches and
carefully remove lower fairing.
4. The lower fluid section of the Turbodisk 2
Applicator, containing the turbine cartridge,
may now be disconnected for continued off
line removal procedures through means of
the "quick disconnect" feature incorporated
into the unit.

> Handle the disk with caution. The sharp edge
can cut even though it is not rotating.
