ROUTINE PREVENTIVE
MAINTENANCE
In general, little maintenance is necessary to
ensure proper operation. It is important,
however, to keep the interior of the unit
clean and free from moisture or foreign
material. For this reason:
1.Keep the exterior of the unit free from dust
accumulation.
2.Always clean the exterior prior to opening
the cabinet door.
3.Open the cabinet door only to perform
maintenance or repair.
4.If the power supply end of the high voltage
cable becomes dirty, clean the end of the
cable with a suitable, clean, non-polar
solvent and apply a light coat of dielectric
grease. On a yearly basis, check to ensure
that the dielectric grease (70863-00) is
covering the electrical contact point in the
High Voltage Tube. If not, add grease as
needed.
As each installation is unique, this infor-
mation is intended to provide general in-
stallation information for the 9060 High
Voltage Controller. Consult your author-
ized Ransburg distributor for specific di-
rections pertaining to the installation of
your equipment.

Equipment Required:
Ohmmeter—To Measure Resistance
If shocks or sparks are noticed at any point
in the spray system, immediately turn off the
power supply and check the complete
system for proper grounding. Proper
grounding of the spray gun system can be
verified as follows:
1. Ensure that the clamp of the 14 AWG
Ground Wire Assembly is connected to
true earth ground. The resistance
between the clamp and a known earth
ground should read less than 10 ohms.
2. Place one end of the ohmmeter on the
clamp of the Ground Wire Assembly and
the other end on the Power Supply
ground stud. If the ohmmeter reads
greater than 10 ohms, replace the 14
AWG Ground Wire Assembly.
3. Connect one end of the ohmmeter to the
Power Supply ground stud and the other
to the metal gun handle. If the ohmmeter
reads greater than 10 ohms repair or
replace the high voltage cable.
KV Output Test
When a lack of high voltage at the spray gun
indicates a problem, a kV Output Test of the
Power Supply may be performed to help
determine whether it is at fault.
Equipment Required:
Calibrated Ransburg High Voltage Test
Probe and Meter (76652-01)
KV Output Test
Procedure
1. Turn AC power to the power supply OFF.
