Fluid Tip Removal

NOTE: Due to the self-cleaning nature of the

fluid tip and needle combination; it is impera-

tive that both parts are changed together when

increasing or decreasing the fluid tip size.

To replace or change the fluid tips:

1. Ensure the spray gun is depressurized.

2. Remove the air cap retaining ring and air

cap.

3. Using the DUX 10mm fluid tip driver, remove

the fluid tip and inspect the threads for wear

or contamination.

4. Install a new fluid tip and tighten using the

DUX 10mm fluid tip driver.

IMPORTANT:

Do not over-tighten.

maximum of 18 INCH pounds of torque or a

half turn past hand tight. The precision

machining of the DUX Automatic makes the

use of a gasket unnecessary.

IMPORTANT: To maintain the precise fit and

seal between the fluid tip and the stainless

steel fluid barrel, paint must not be allowed to

dry on the threads. The threads of both the

fluid barrel and tip must be thoroughly cleaned

after each use.

5. Replace air cap and air cap retaining ring.

IMPORTANT: Some coating leakage out of

the fluid tip may indicate an adjustment of the

packing is needed. This is not an indication of

the spray gun failing.

Always ensure the spray gun is depressurized

before making adjustments.

Fluid Packing Adjustment

The fluid packing in all DUX spray guns is set

pre-determined

assembly. Therefore, depending on the type of

material being sprayed, it is possible that the

packing will need adjustment upon start-up or

after some amount of spraying.

Fluid leakage at the front of the spray gun is

an indication that the fluid needle is not

seating properly in the fluid tip. This may be

caused by dried material in the tip, or if the

fluid packing is too tight. If the packing is set

too tightly for a particular material, the needle

will not to fully seat in the fluid tip and will

require adjustment.

The DUX Automatic features a leak indicator

in the form of a pin hole located above the

mounting bolt (See Figure 9). Fluid leakage at

this pin hole indicates that the fluid packing is

too loose and will need tightening.
