SCHEDULES
Periodic
To assure continuous, efficient, trouble free operation of
the No. 2 Handgun, periodic inspection of the components
is required. Clean, repair and/ or replace any defective
components as required.
Daily
1. Prior to start-up, inspect all components of the system
for defective or broken parts and repair or replace.
2. Inspect the bell for chips or cracks and replace as needed.
3. Ensure the equipment is installed properly. See the
“Installation” section.
4. Clean the fluid line filter. See “Filter Cleaning or Re-
placement” in the “Maintenance” section of this manual.
Weekly
1. Inspect all equipment for damage, leaks, or paint buildup.
2. Measure the electrical output of the gun. The short
circuit current should be 80 to 115 microamperes (.08 to
.115 milliamperes on some meter scales). Refer to the
“Gun Output Test (SCI)” in the “Maintenance” section
for procedure.
Check
ALL
o-rings for fit and deterioration.
Prior to gun disassembly, flush line and gun with a
suitable solvent. Loosen the set screw on the bell hub,
remove, and clean the bell with a soft brush (nonme-
tallic) or cloth and a suitable solvent. The bell
MUST
be cleaned if spraying is to be interrupted for more
than a few minutes.
NEVER
wrap the applicator, associated valves
and tubing, and supporting hardware in plastic to
keep it clean. A surface charge may build up on the
plastic surface and discharge to the nearest grounded
object. Efficiency of the applicator will also be reduced
and damage or failure of the applicator’s components
may occur.
WRAPPING THESE COMPONENTS IN
PLASTIC WILL VOID WARRANTY

TEST PROCEDURES
Fluid Testing
Needle Locknut Adjustment
When the paint does not shut-off after the trigger has been
released, adjust the knurled nuts (in front of trigger). If this
does not correct the problem, refer to the “Troubleshooting
Guide” in the “Maintenance” section.
1. Turn the outer locknut a few times counter-clockwise.
DO NOT
thread it off the needle.
2. Adjust the inner locknut counter-clockwise, to allow the
needle to completely seat, and hold the trigger firmly.
3. Make further adjustments of the outer and inner locknuts
as needed for fine adjustment of fluid delivery with thin
viscosity paints.
Electrical Testing
If an electrical malfunction should occur in the system, check
the hand gun, high voltage cable, supply fuses, and the
power source according to the prescribed test procedures for
each. After these electrical tests have been completed and
it is determined that a fault may exist in the power supply,
make the high voltage short circuit current test as indicated
in the power supply service manual.
Primary fluid pressure control is from the paint
pot regulator.
These tests should be made as advised under
the “Maintenance” section of the manual.

Gun Voltage Output (SCI)
The Short Circuit Current (SCI) will determine if the high
voltage portion of the system is operating correctly by shorting
the maximum current flow to ground. The SCI reading on
either the power supply current meter and/or the externally
connected meter at the contact brush should be between 80
and 115 microamperes (.08 and .115 milliamperes). Readings
outside this range indicate possible component failure and
indicate the need for further testing and/or repair. There are
two procedures that can be used to perform an SCI Test.
