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, 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 WARNING WARNING FIRE AND EXPLOSION HAZARD Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent fire and explosion: • Do not spray flammable or combustible materials near an open flame or sources of ignition such as cigarettes, motors, and electrical equipment. • Paint or solvent flowing through the equipment is able to result in static electricity. Static electricity creates a risk of fire or explosion in the presence of paint or solvent fumes.
Warnings WARNING WARNING SKIN INJECTION HAZARD Do not aim the gun at, or spray any person or animal. • Keep hands and other body parts away from the discharge. For example, do not try to stop leaks with any part of the body. • Always use the nozzle tip guard. Do not spray without nozzle tip guard in place. • Use Airlessco nozzle tips. • Use caution when cleaning and changing nozzle tips.
Warnings WARNING WARNING MOVING PARTS HAZARD Moving parts can pinch, cut or amputate fingers and other body parts. • Keep clear of moving parts. • Do not operate equipment with protective guards or covers removed. • Pressurized equipment can start without warning. Before checking, moving, or servicing equipment, follow the Pressure Relief Procedure and disconnect all power sources.
Component Identification Component Identification B E D ti17301a C 6 A A Power switch Turns sprayer ON and OFF B Pressure Control Knob Adjusts pressure. Turn clockwise to increase pressure and counterclockwise to decrease pressure. C Prime/Pressure Relief Valve Primes pump and relieves pressure from gun, hose and tip. D Prime/Pressure Relief Valve Open Position Relieves pressure from gun, hose and tip and primes the unit when in the open position.
Operation Operation Pressure Relief Procedure 5. Re-engage gun trigger lock and close Prime/Pressure Relief Valve. When in the closed position there is only a very slight gap To reduce risk of injury, follow this pressure relief procedure whenever you see this symbol throughout this manual, Also, perform this procedure whenever you: • Stop spraying • Check or repair any part of this system ti14790a • Install or clean spray nozzle 1. Engage the gun trigger lock.
Operation Flushing Fill the Packing Nut/Wet Cup 1. Fill the Packing Nut/Wet Cup with 5 drops of Airlessco Throat Seal Oil (TSO). • To reduce the risk of static sparking, which can cause fire or explosion, always hold a metal part of the gun firmly against the metal pail when flushing. This also reduces splashing. • Always remove the spray tip before flushing. ti16049a Flush the Sprayer 1. Flush the sprayer. See Flushing Procedure on page 8. 1.
Operation 6. Turn the engine ON/OFF switch to ON. Startup 7. Point the gun into the metal pail and hold a metal part of the gun firmly against the pail. Maintain firm metal to metal contact between gun and container. 1. Prepare the material according to the material manufacturer’s recommendations. 2. Place the suction tube into the material container. 3. Start the sprayer. ti15989a 8. Disengage the gun trigger lock and squeeze the trigger.
Operation Adjusting the Pressure Storage Short Term • To reduce the risk of injection, never hold your hand, body, fingers or hand in a rag in front of the spray tip when cleaning or checking for a cleared tip. Always point the gun toward the ground or into a waste container when checking to see if the tip is cleared or when using a self cleaning tip. • When you spray into the paint bucket, always use the lowest spray pressure and maintain firm metal to metal contact between the gun and container.
Maintenance Maintenance Daily Maintenance Keep displacement pump packing nut/wet cup 1/3 full of Airlessco Throat Seal Oil at all times. The TSO helps protect the packings and rod. Inspect the packing nut daily. If seepage of paint into the packing nut and/or movement of the piston upward is found (while not spraying), the packing nut should be tightened just enough to stop leakage. Overtightening will damage the packings and reduce the packing life.
Maintenance Fluid Pump Reinstall 1. Loosen the packing nut and ensure the piston rod (10) is in its upper position in the fluid pump body (9), snap cap (4) onto packing nut and slip the sleeve (2) and the retaining ring (3) over the piston rod (10). 2. Push the piston rod (10) up into the connecting rod (2) and align the holes. Insert the connecting rod pin (1) through the connecting rod (2) and piston.
Maintenance Packing Replacement Procedures Disassembly of the Fluid Pump 1. Disconnect the Fluid Pump, page 11. 2. Unscrew and remove the packing nut, with wet cup cap. 3. Push the piston rod down through the packings and out of the pump. 4. Now push the packing removal tool up through the pump and remove from the top bringing packings, spacer and springs along with it, leaving fluid body empty. Make sure all old packings and glands have been removed from fluid pump. 5. Clean inside of fluid body. 6.

Lay unit on its back and disassemble gearbox. 16 4 15 5 6 5.
Maintenance Replacement of Electrical Components 4. Using a 1/2” wrench or deep socket, remove the nut from the potentiometer shaft assembly. 5. Pull entire potentiometer assembly out of the terminal box. Always unplug the electrical cord before servicing the machine. NOTE: Anytime the pressure control assembly, sensor, or both are replaced, perform the calibrations. Pressure Control Assembly (Electrical Control Board) 1. Unplug machine’s power cord. 6. Replace in reverse order.
Troubleshooting Troubleshooting General Problem Unit doesn’t prime Unit primes but has poor or no pressure Unit does not maintain good spraying pressure Unit does not run Machine does not start 16 Cause Solution Airleak due to loose suction nut Tighten suction nut. Airleak due to worn o-rings Replace o-ring (108526) on suction seat and o-ring (867370) below suction seat. Airleak due to hole in suction hose Replace suction hose Stuck or fouled balls Service inlet and outlet valves.
Troubleshooting Problem Machine does not start Cause Motor Solution Remove the motor brush covers and turn the machine ON. Set the potentiometer (POT) at maximum pressure and check for DC voltage across both brush terminals. It should read greater than 80 volts DC. If you have DC voltage, turn the machine off and unplug it from the wall. Check to make sure the brushes are making good contact with the armature. Replace the brushes if they are less than 1/2” long.
Troubleshooting Pressure Control Repair Motor Control Board Diagnostics 1. For sprayers with digital display, see Digital Display Messages, page 19 2. Remove screws and cover. 3. Turn ON/OFF switch ON. Relieve pressure and unplug sprayer before servicing control board. See Pressure Relief Procedure, page 7. 4. Observe LED operation and reference following table: NOTE: Keep a new transducer on hand to use for test. NOTICE Do not allow sprayer to develop fluid pressure without transducer installed.
Troubleshooting Digital Display Messages No display does not mean that spayer is not pressurized. Relieve pressure before repair. See Pressure Relief Procedure, page 7 DISPLAY SPRAYER OPERATION No Display Sprayer stops. Power is not applied. Sprayer may be pressurized. Loss of power. Check power source. Relieve pressure before repair or disassembly. Sprayer is pressurized. Power is applied. (Pressure varies with tip size and pressure control setting.
Troubleshooting Airless Spray Gun Problem Cause Coarse spray Excessive fogging (overspray) Low pressure High pressure Pattern too wide Pattern too narrow Material too thin Spray angle too large Spray angle too small Too much material Too little material Thin distribution in center of pattern “horns” Thick skin on work Solution Increase the pressure Reduce the pressure to satisfactory pattern distribution.
Troubleshooting Servicing the Inlet Valve Servicing Gear Box Assembly 1. Un-thread and remove suction nut from the fluid pump body (8). 2. Remove suction seat (12), O-ring (11), suction ball (10) and ball guide (9). Ensure cover guard is in place before operating. 1. Remove fluid pump, see page 11. 3. Clean all parts and inspect them for wear or damage, replacing parts as needed. 2. Remove frame from the gearbox by loosening the four mounting screws. 4. Clean inside of the fluid pump body (8). 5.
