If spraying water-based material or a material that could harden in the sprayer overnight, flush the sprayer after use. See Flushing, page 8. Storage Short Term 1. Flush sprayer with compatible solvent before storing, then fill the pump and hoses with an oil based solvent such as mineral spirits or Graco or Airlessco Pump Armor.
Maintenance Maintenance Electric Motor Maintenance Regular Maintenance 1. Always stop the pump at the bottom of its stroke when you take a break or at the end of the day. This helps keep material from drying on the rod, damaging the packings. 2. 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. 3. Lubricate Connecting Rod Pin every 3 months. Daily Maintenance Inspect the packing nut daily.
Maintenance Replacement of Belt/Belt Adjustment Servicing the Fluid Pump NOTE: The Cog Belt System does not require alignment. When upper sheave is placed on motor shaft it is pushed on until a positive stop is reached. The set screws are then loctited. The lower pulley is placed on gearbox and held in place with keyway and snap ring. The flange on upper sheave holds the belt in alignment and the belt self aligns on lower pulley eliminating having to align.
Maintenance Fluid Pump Reinstall 1. Loosen the packing nut and extend piston rod to fully up position. Slip sleeve over the piston rod. 4. Remove the retaining ring from the packing nut and insert into coupling halves. ti15998a 5. Secure the fluid pump housing to the tie rods and screw locknuts with washers on loosely. ti16033a 2. Insert one of the retaining rings through the packing nut and rest the sleeve on top of it. 6. Tighten the tie rod locknuts evenly to 30 ft. lb.
Maintenance Servicing Inlet Nut and Outlet Valve Inlet Valve 6 1. Using the rod collar tool (865008), unscrew the suction nut (6), containing suction seat support (5), off of the fluid body. 2. Remove suction seat (3), O-ring (2), suction ball (1) and suction ball guide (8) with O-ring (2). 3. Clean all parts and inspect them for wear or damage, replacing parts as needed. Old O-rings (2) should be replaced with new ones. NOTE: Suction seat (867574) is reversible. Piston Outlet Valve 1.
Maintenance Packing Replacement Procedures Disassembly of the Fluid Pump 1. Unscrew and remove the packing nut (2). 2. Push the piston rod (1) down through the packings and out of the pump. 3. Now push the packing removal tool up through the pump and remove from the top bringing the packings, spacer (4) and springs along with it, leaving fluid body (3) empty. NOTE: Make sure all old packings and glands have been removed from fluid pump. 6.
Maintenance 19. Take the completed suction valve assembly and place it into the bottom of the fluid body (3), with the rounded side fitting inside. 17. Thread the packing nut (2) into the top of the fluid body (3) and tighten hand tight. 18. Take the suction retainer (10) and replace the black O-ring (26) with a new one from the packing kit. Replace the suction ball (11) with a new one from the kit into the suction retainer (10).
Maintenance Pressure Control Assembly Calibration NOTE: Anytime a sensor or pressure control assembly (board) or both are replaced, the following calibrations must be performed. NOTE: Pressure control assemblies (boards) are now being equipped with a green grounding wire attached. Connect the grounding wire to terminal box using the same screw that holds the grounding wire from the power cord. Pressure Calibration 1.
Maintenance Phase Limit Calibration Sensor Formerly known as the low voltage or master voltage calibration. 1. Remove the screws and lower the pressure control assembly. 1.

Troubleshooting Troubleshooting General Problem Unit doesn’t prime Unit primes but has poor or no pressure Unit does not maintain good spraying pressure Cause Airleak due to loose suction nut Tighten suction nut. Airleak due to worn o-rings Replace o-ring (110636) on suction seat and o-ring (867390) below suction seat. Stuck or fouled balls Service inlet and outlet valves. Prime/Pressure Relief valve not opening Clean or replace Prime Valve (866428) Pressure set too low Turn up pressure.
Troubleshooting Problem Cause Power Source Solution Using a Phillips Head screwdriver, remove the eight screws holding the pressure control assembly. Locate the red light on the board indicating there is power. If the light is ON, see Pressure Control Assembly (Board). If the light is OFF, locate the L1 and L2 terminals on the board. Use the multi-meter to ensure there is 110 volts AC across the two terminals (the cord wires will still be attached.
Troubleshooting Problem Cause Sensor Solution Plug another sensor board into the board and perform the zero calibration procedure. If the machine starts to run, the sensor is bad. If there is no replacement sensor available, use a multi-meter to test the resistance across the red and black wires of the sensor (be sure to test the plug). You should read 1.5 - 3.5k ohms. A faulty sensor usually reads no continuity (open). If the sensor passes all the tests, see Pressure Control Knob (Potentiometer).
Troubleshooting Problem Cause Solution Thin distribution in center of pattern “horns” Worn tip Change to new tip Wrong tip Use tip with narrow spray angle Thick skin on work Material too viscous Thin cautiously Application too heavy Reduce pressure and/or use tip in next smaller tip size Coating fails to close and smooth over Material too viscous Thin cautiously Spray pattern irregular, deflected Orifice clogged Clean carefully Tip damaged Replace with new tip Craters or pock marks, bu
