Setup and Assembly Any missing parts or damage should be reported immediately to your JET® distributor. Do not use a damaged tool. Read this instruction manual thoroughly for operation, maintenance and safety instructions.

Blow out air line to remove any dirt or moisture, then connect air supply hose to tool's air inlet. IMPORTANT: Connecting a quick-change coupling directly to the tool is not recommended, as vibration may cause the connection to fail. Instead, add a leader hose and install any quick-change couplings farther down the line. 2. Unscrew cup lid and add fluid to be sprayed. (Follow paint manufacturer's instructions for proper mixing.) 3. Set regulator to desired air pressure. (Refer to gun's rated maximum pressure). 4. Loosen air cap knurled ring and rotate air cap horns to effect horizontal or vertical spray. Retighten air cap. Horizontal horns (as shown in Figure 1) will produce vertical pattern for side-to-side motion. Vertical horns produce horizontal pattern used for top-to-bottom motion. 5. Squeezing trigger part way opens air valve. Squeezing further retracts fluid needle, thus releasing fluid where it is atomized by the air flowing through air cap. 6. Rotate fluid control knob clockwise to decrease flow of material, counterclockwise to increase. Tighten locking knob to secure setting. 7. Rotate fan control knob counterclockwise for full, flat spray pattern; clockwise for narrower pattern. NOTE: To reduce overspray and obtain maximum efficiency, always spray with the lowest possible air pressure/fluid flow combination. Figure 1 Spray gun movement The gun should be held perpendicular to surface being covered, and moved parallel with it at a consistent pace. See Figure 2. The stroke should be started before the trigger is pulled, and the trigger released before the stroke is ended. Distance between gun and surface should be 6 to 12 inches depending upon material and atomizing pressure. Deposited material should be even and wet. Lap each stroke over the preceding stroke from 1/3 to 1/2, to obtain a uniform finish. JET 7
