The quality of atomization can be tested
by shooting a donut test pattern on a
grounded flat surface at approximately a
6-inch target distance. Coarse atomization
may be caused by excessive fluid delivery
(high fluid pressure or wrong bell size) or
improper electrical resistance of the coating
material. Adjust parameters according to
atomization quality and results.

The green indicator shows AC power
into the power supply, and the red pilot
light indicates high voltage power to the
handgun.

It is important, while operating, to keep
the gun positioned toward the grounded
target to avoid paint wrapback onto the
operator or nearby objects.

Prior to operating the No. 2 Handgun, ensure
that the equipment is installed properly (see "In-
stallation" section of this service manual). Ob-
serve and follow the safety requirements at ALL
times.
1.
Inspect the rotating bell assembly (item
66) to ensure that it is clean and is not
chipped. Replace or clean the bell as-
sembly when necessary.
2.
Set the paint fluid pressure at 3 to 4 psi
(0.2 to 0.3 kg/cm
2
). Adjust the pressure
up or down for the desired fluid delivery.
Higher fluid pressure may be needed
with higher viscosity material, longer
hoses, or higher fluid deliveries.
3.
Set the switch (item 26) to the off posi-
tion prior to turning the power supply on.
Turn the AC power ON at the power
supply (and at the remote switch in the
booth on permanent installations).
4.
Turn the No. 2 gun motor ON at the
switch (item 26) on the rear of the hand-
gun.
5.
Hold the No. 2 handgun perpendicular
to, and 4 to 7 inches (13 to 18 cm) from
the part being coated. Trigger the hand-
gun and observe the atomization of the
coating material.
Rotational speed of the bell will be ap-
proximately 600 rpm.

6.
Move the No. 2 handgun in a smooth
horizontal or vertical line or in a smooth
circular motion, maintaining a constant
distance between the target and the bell
surface. (See Ransburg manual IL-211,
"No. 2 Handgun Spray Techniques").
For an accurate measurement of paint
delivery with any paint being used, turn the
handgun motor OFF, and remove the bell.
Using a graduated cylinder or beaker and a
stopwatch, trigger the gun and collect the
fluid for one minute. Measure the paint vol-
ume collected to get fluid flow rate per
minute. See maximum "Fluid Delivery
Rate" under "Specifications" in the "Intro-
duction" section of this manual.
