4 308351 W ARNING SKIN INJECTION HAZARD Spray from the spray gun/dispense valve, leaks or ruptured components can inject fluid into your body and cause extremely serious injury , including the need for amputation. Fluid splashed in the eyes or on the skin can also cause serious injury .
308351 5 W ARNING FIRE AND EXPLOSION HAZARD Improper grounding, poor ventilation, open flames or sparks can cause a hazardous condition and result in a fire or explosion and serious injury . D Ground the equipment and the object being sprayed. Refer to Grounding on page 6.
6 308351 Installation Grounding W ARNING FIRE AND EXPLOSION HAZARD Before operating the pump, ground the system as explained below . Also read the section FIRE AND EXPLOSION HAZARD on page 5. 1. King Pumps: use a ground wire and clamp. See Fig. 1. Remove the ground screw (Z) and insert through eye of ring terminal at the end of ground wire (Y).
308351 7 Installation All Systems NOTE: Reference numbers and letters in parentheses in the text refer to the callouts in the figures and parts drawings. The T ypical Installations shown in Figs. 3 and 4 are only guides for selecting and installing system compo- nents and accessories.

308351 11 Installation (Hydraulic–Powered Pumps) CAUTION The Hydraulic Power Supply must be kept clean at all times to avoid damage to the motor and hydraulic power supply . 1. Blow out hydraulic lines with air and flush thor- oughly before connection to the motor .
12 308351 Operation Pressure Relief Procedure W ARNING SKIN INJECTION HAZARD The system pressure must be manually relieved to prevent the system from starting or spraying accidentally . Fluid under high pressure can be injected through the skin and cause serious injury .
308351 13 Operation Flush the Pump Before First Use The pump is tested with lightweight oil, which is left in to protect the pump parts. If the fluid you are using may be contaminated by the oil, flush it out with a compatible solvent. See Flushing on page 16.
14 308351 Operation Hydraulic–Powered Systems Refer to the warnings on page 13. 1. Supply fluid to the pump, per the requirements of your system. 2. Open the shutoff valves between the pump and supply tanks. 3. Open the dispensing valve(s) or spray gun(s).
308351 15 Notes.
16 308351 Maintenance Shutdown and Care of the Pump W ARNING T o reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 12.
308351 17 T roubleshooting W ARNING T o reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 12. 1. Relieve the pressure. 2. Check all possible problems and causes before disassembling the pump.
18 308351 T roubleshooting PROBLEM CAUSE SOLUTION Erratic or accelerated pump speed. Exhausted fluid supply . Refill and prime. Fluid is too heavy for pump priming. Use the bleeder valve (see page 13 or 14); use a ram. Held open or worn piston valve or seals.
308351 19 Service Reconnecting the Displacement Pump 1. Make sure the coupling nut (104) and the coupling collars (105) are in place on the displacement rod (1). See Fig. 6. 2. Use at least two people to hold the displacement pump while another reconnects it to the motor (see the CAUTION on page 18).
20 308351 Displacement Pump Service Disassembly When disassembling the pump, lay out all the removed parts in sequence, to ease reassembly . Clean all parts with a compatible solvent and inspect them for wear or damage. Refer to Fig. 9 for a cutaway view of the pump.

Pull the intake seat (37) and seal (38) out the bottom of the intake valve housing (17). T ake care not to drop the check valve assembly (V) as it comes free, and set it aside for later .
22 308351 Displacement Pump Service 9. Remove the seal (8) from the bottom of the cylin- der (10). See Fig. 12. Shine a light into the cylinder to examine the inside surface for scoring or dam- age.
308351 23 Displacement Pump Service Reassembly Fig. 16 shows a cutaway of the entire pump. 1. Lubricate the intake packings and install them in the valve body (16), with the lips of the v-pack- ings facing up. Install the v-packings in the order shown in Fig.
24 308351 Displacement Pump Service 7. If the cylinder (10) was removed from the outlet housing (9), lubricate the seal (8*) and place it on the top of the cylinder . (The cylinder is symmetri- cal, so either end can be the top.) Screw the cylinder into the outlet housing.
308351 25 Displacement Pump Service 15. Screw the intake cylinder (19) into the intake housing (17). Using a pipe wrench on the hex of the cylinder (19), torque the cylinder to 468–590 N.m (345–435 ft-lb). This will also torque the intake valve housing (17) and pump cylinder (10) into the outlet housing (9).
