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 PERSONAL PROTECTIVE EQUIPMENT You must wear appropriate protective equipment when operating, servicing, or when in the operating area of the equipment to help protect you from serious injury, including eye injury, hearing loss, inhalation of toxic fumes, and burns. This equipment includes but is not limited to: • Protective eyewear, and hearing protection. • Respirators, protective clothing, and gloves as recommended by the fluid and solvent manufacturer.
Installation Installation Grounding Object being sprayed: follow local code. The equipment must be grounded. Grounding reduces the risk of static and electric shock by providing an escape wire for the electrical current due to static build up or in the event of a short circuit. Pump: use a ground wire and clamp (Y). See FIG. 1. Loosen the grounding lug locknut (W) and washer. Insert one end of the ground wire into the slot in the lug and tighten the locknut securely.
Installation Plumbing • Pump air regulator (L): to control pump speed and outlet pressure. Locate close to the pump. See FIG. 2. Install a fluid shutoff valve (D) between the mix tank (A) and the pump. • Air line filter (K): removes harmful dirt and moisture from compressed air supply. When using a stainless steel pump, use stainless steel plumbing to maintain a corrosion-resistant system. • Second bleed-type air valve (H): isolates air line accessories for servicing.

Operation Operation Pressure Relief Procedure 1. Close the bleed-type master air valve (M). 2. Open the dispensing valve, if used. 3. Open all fluid drain valves (N) in the system, having a waste container ready to catch drainage. Leave drain valve(s) open until you are ready to pump again. Prime the Pump 1. Fill the TSL reservoir to the Maximum fill line with Throat Seal Liquid (TSL). See FIG. 3 on page 10. NOTE: During operation the TSL level in the reservoir will fluctuate slightly at pump changeover.
Maintenance Maintenance Preventive Maintenance Schedule The operating conditions of your particular system determine how often maintenance is required. Establish a preventive maintenance schedule by recording when and what kind of maintenance is needed, and then determine a regular schedule for checking your system.
Maintenance Changing the TSL To change the TSL: Check the condition of the TSL and the level in the reservoir every week, minimum. TSL should be changed at least every month. 1. Shut off the pump. Part No. 206995 Throat Seal Liquid (TSL) carries residue from the pump rod into the reservoir. Discoloration of the TSL fluid is to be expected during normal operation. After some time the TSL will thicken and darken, and must be replaced.
Troubleshooting Troubleshooting Problem Pump output low on both strokes. Cause Solution Restricted air supply lines. Clear any obstructions; be sure all shutoff valves are open; increase pressure, but do not exceed maximum working pressure. Exhausted fluid supply. Refill and reprime pump. Clogged fluid outlet line, valves, etc. Clear. Worn piston packing. Replace. See lower manual. Held open or worn ball check valves. Check and repair. Worn piston packings. Replace. See lower manual.
Repair Repair Disassembly Reassembly NOTE: If the coupling adapter (108) and tie rods (104) have been disassembled from the motor, see Reassemble the Coupling Adapter and Tie Rods to the Motor on page 13. 1. Relieve the pressure, see Pressure Relief Procedure page 8. 1. See FIG. 5. Assemble the coupling nut (110) to the piston rod (R). 2. Disconnect the hoses from the lower and plug the ends to prevent fluid contamination. 3. See FIG. 4.
Repair Reassemble the Coupling Adapter and Tie Rods to the Motor 4 113 NOTE: Use this procedure only if the coupling adapter (108) and tie rods (104) have been disassembled from the motor, to ensure proper alignment of the motor shaft to the piston rod (R). 101 112 1. See FIG. 5. Screw the tie rods (104) into the motor (101) and torque to 50-55 ft-lb (68-75 N•m). 2. Fill the cavity in the bottom of the motor shaft with grease. Lubricate the threads of the coupling adapter (105).
