offering the following features:
•Easy to operate and maintain
•Light weight
•Ergonomically balanced
•Hydraulically actuated
•Non-adjustable
•Rebuildable
Before proceeding with the following procedures, familiarize yourself with the parts of
the GX-14 Gun (Figure 1), so that you may relate to them as you read this manual.

Although new and unique in many aspects, the mixing chamber utilizes direct
impingement mixing while the 1/4” valving rod allows for many hours of self-cleaning
use. The GX-14 Mixing Chamber provides the following features:
•Self-cleaning
•Direct impingement
•Various nozzles to choose from dependent on application
•Specific orifice sizes can be specified
•Rebuildable
•Warranted for 50,000 shots (based on 2 seconds between shots)
•No adjustments required
Before proceeding with the following procedures, familiarize yourself with the parts of
the GX-14 Mixing Chamber Assembly (Figure 2), so that you may relate to them as you
read this manual.

PROCEDURE
1. Verify GX-14 Hydraulic Power Pack or equivalent is off.
2. Install hydraulic hose to the power pack. Hoses should be 1/4” ID rated for ≥2500
psi working pressure and greater than 15’ in length.
3. Connect end of hoses together utilizing a 7/16” JIC male / 7/16” JIC male adapter
at gun end.
4. Turn on power pack. Pressure should not increase while air is purged from
hydraulic hoses.
5. Turn power pack off. Verify that no pressure exists.
6. Remove hydraulic adapter utilized in step 3 and attach hoses to GX-14 gun as
indicated on diagram.
7. Set power pack in manual mode.
8. Attach proximity switch cable and trigger switch cable to GX-14 gun and GX-14
Power Pack.
NOTE:
A two second delay between
triggering of gun is required to
ensure life of mixing chamber. 9. With chemical hoses unattached, trigger GX-14 “only” two or three times. This
will purge the air that was remaining in gun.
10. Verify GX-14 Hydraulic Power Pack pressure is between 1800 and 2500 psi.
Adjust power pack if required.
NOTE:
If during normal operation the
valving rod does not retract in
mixing chamber and the hydraulic
pressure is 2500 psi, contact
technical service department.
11. Install chemical hoses / coupling block
