REM Automatic Applicator - Maintenance

3. Thread High Voltage Test Assembly to barrel
of the applicator.

4. Attach ground clip to a ground source.

W A R N I N G

!!!!!

Injury to personnel and damage to equipment

is probable if the ground clip is NOT ATTACH-
ED. Voltage is present at the clip. This step
MUST be accomplished before voltage is
applied.

5. Turn power “ON” at Control Unit and trigger
high voltage to the applicator. Adjust kV output of
80.

6. Monitor the meter on the High Voltage Output
Test assembly. At 80 kV the meter should read
35 (±10%) microamps.

7. Replace cascade/barrel if proper readings are
not obtained.

8. If proper readings are obtained, the problem is
not in the applicator. Check paint, solvent, ground,
etc.

Atomizer Assembly Cleaning

Equipment needed:

• Appropriate solvent
• Solvent safety container (grounded)
• Small soft-bristled brush

1. Unscrew nozzle nut [1] from barrel [18].

2. Remove air [2] and fluid [3] nozzles.

3. Clean all parts in a compatible solvent and
examine for wear and damage. To clear orifices,
blow compressed air through the fluid nozzle
assembly in the opposite direction from the fluid
flow. Soaking in solvent and/or brushing may also
be necessary to clean the orifice. Replace as
necessary.

It may be necessary to soak some

parts in solvent and a soft bristle brush to
clean. Never use metal tools or wires or
metal bristle brushes to clean or unclog
nozzle assemblies.

Do NOT soak or submerge the applicator.

Soaking may cause permanent damage to the
applicator and result in unsafe operating condi-
tions.

4. Reassemble the parts in reverse order of
disassembly. When reassembling the seal, be
sure that the 45

° chamfered portion is properly

seated in the nozzle assembly before reattaching
the nozzle.

Flushing Fluid Hose and
Applicator

Applicator

The fluid system should be thoroughly cleaned
by flushing with a clean compatible solvent
whenever a color change is made, or when the
applicator will not be used for any extended period,
for example, a weekend or longer. Proceed as
follows:

1. Turn control unit OFF.

2. Turn off pump air supply. trigger applicator until
fluid flow ceases. Turn off shaping air supply.

3. Remove nozzle nut [1], air [2], and fluid nozzles
[3].

!!!!!

If the nozzle is completely clogged, triggering

the applicator will not release the pressure.
Cover the end of the applicator with a heavy
rag and loosen the retaining cap slowly into a
catch container.
