Warnings Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this manual where applicable.
Warnings SKIN INJECTION HAZARD High-pressure fluid from dispensing device, hose leaks, or ruptured components will pierce skin. This may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment. • Engage trigger lock when not dispensing. • Do not point dispensing device at anyone or at any part of the body. • Do not put your hand over the fluid outlet. • Do not stop or deflect leaks with your hand, body, glove, or rag.

Setup Setup 4 5 Air hose fittings can get hot! Allow sprayer to cool down 15 minutes before removing air hose. 1. Connect air and material hoses to gun. Firmly tighten connections. ti28086a 4. Refer to sprayer operation manual to start and prime the sprayer. Pressure Relief Procedure Follow the Pressure Relief Procedure whenever you see this symbol. ti28143a 2. If using WideTex adapter, install disc (2) on front of adapter (3) with retaining ring (1).
Setup Spray Disc and Nozzle Selection • • Standard nozzles (4) are numbered 3, 4, 6, 8, 10 and 12, designating orifice size in millimeters. These parts can be interchanged to produce a pattern suitable for each job. For smaller droplet sizes, reduce nozzle (4) and/or disc (2) size and increase gun atomizing air by opening air valve (A) (counter-clockwise). • For larger droplets, increase nozzle (4) and/or disc size (2) and reduce gun atomizing air by closing air control valve (A) (clockwise).
Gun Adjustments Gun Adjustments Sufficient fluid output (volume and pressure) and good atomization is a balance of atomizing air, material thickness/material flow and nozzle selection. Achieving the correct balance for your application requires experimentation to achieve desired results. Keep in mind these important points when adjusting gun: • • To select correct nozzle for your applications, consider size of aggregate in material and coarseness of spray pattern.
Shutdown and Cleanup Shutdown and Cleanup 5 4 NOTE: Keep pump and hose clean when switching between materials. A dirty pump can release particles of texture into the finish. ti28086a NOTICE Before removing material hose be sure pressure is relieved and material is not in the hose. 4. NOTE: Cleaning out all air passages and components will improve gun performance and life. To keep sprayer in good operating condition, always clean it throughly and prepare it properly for storage.
Repair Repair Repair involves the removal and replacement of worn or damaged parts. 3. Using your finger or a 1/2-in. diameter rod, push new seal (3) in place. Make sure seal is seated against sleeve bearing (35). 4. Insert u-cup retaining ring (41). Make sure retaining ring is seated against u-cup (3). NOTICE U-cup seals are very fragile. Never pound on seal when during assembly. Fluid Seal Replacement For Non-bleeder guns use Seal Replacement Kit, 287228.
Repair Air Seal Replacement (Use Seal Replacement Kit, 287229.) 1. Remove air valve retainer (21), compression spring (19), air valve seal (18) and needle (17) through back of gun. ti28095a 3. Push new seal (4) in place using a small diameter (1/4 in. or smaller) object. Make sure seal is seated against sleeve bearing (36). ti28093a 2. Use a hook-shaped object to carefully pull u-cup seal (4) out of gun. ti28096a 4.
Troubleshooting Troubleshooting 1. Follow , page 6, before checking or repairing. Problem Material will not flow out of gun Pattern too fine Pattern too coarse Gun will not shut off Fluid leaking at flow needle nut (8) 12 2. Check all possible problems and causes before disassembling the unit. What to Check If check is OK, go to next check What to Do When check is not OK, refer to this column Material too thick Thin material. Increase pressure at pump.
Troubleshooting Problem Needle nut won’t adjust Air won’t shut off when gun trigger is released 3A3373C What to Check If check is OK, go to next check What to Do When check is not OK, refer to this column Dirty threads Clean threads. Nozzle not on gun Put nozzle on gun. Needle triggered Adjust when trigger is not pulled. Debris in gun air passages Clean gun.
