FIRE , fluids under high pressure from spray or leaks can penetrate the skin and cause extremely serious injury, including the need for amputation. body. NNER put hand or fingers over the spray tip.
INs1 Check Electrical Service and Plug In Before plugging in the sprayer, be sure the electrical service is 220 V, 60 HzAC, 20 Amp. With the ON-OFF switch in theOFF position, plug thepower supply cord into a grounded outlet. Do not remove the third prong of the plug1 If youuse an extension cord, it m i s t have 3 wires of at least 12 gauge (2.5 mm2) and should not be over 100 ft (30.3 m) long. Install Wheels and Handle Slide the axle through theframe.
CAUTION B Never run thecleaning unit dry. Costly damage to the pump will result. Always be sure the water supply is completely turned on before operating. Inspect all connections for any leaks. Tighten if necessary. Cleaning For cleaning with harsh chemicals, see the Chemical Injector Kit manual 801-192. For cleaning with clear water, test the distance you will need to hold the spray nozzle from the surface on a scrap piece of similar material.
DISCHARGE VALVES & VALVE SEATS Disassembly 1. Loosen the 2 (M8) locking nuts about one turn. 2. Then remove the 2 (M8) flange nuts. 3. Grasp the discharge manifold with 3 fingers on the underside and tap with a soft mallet to remove. 4. Valve assemblies will remain withthe manifold. Invert manifold anddischarge valve assemblies should fall out. 5. Inspect discharge valves for wear of ridges. (Spherical valves must be replaced when worn.) Reassembly 1 . Place retainer in manifold chamber. 2.
Reassembly 1. Examine inlet valve surface and reverse if damaged. (Both sides are lap surfaces.) 2. Examine piston assembly for clean inlet surface. If damaged, replace and lubricate. NOTE: SEALS AND SLEEVES Disassembly 1. Remove discharge manifold and piston assemblies as described. 2. Remove both (ME) locking nuts from studs CUP INSTALLATION Wipe cup inserter lightly with oil. Slip backup ring ontopiston. Force cup over inserter and square with all surfaces.
SOLUTION Fouled or dirty inlet or discharge valves. Clean inlet and discharge valve assemblies. Worn inlet or discharge valves. Leaky discharge hose. Replace worn valves, valve seats and/c discharge hose. Pump runs extremely rough, pressure very low Inlet restriction andlor air leaks. Damaged cup or stuck inlet or discharge valve. Replace worn cup or cups, clean out foreign material, replace worn valves. Worn inlet manifold seals. Replace worn seals.
DIAGNOSIS AND MAINTENANCE CONT I PROBLEM Short cup life (Cont.) Strong surging a t h e inlet and low pressure on the discharge side. Water leaking from valve stem II Short piston seal life. PROBABLE CAUSE SOLUTION Abrasive material in the fluid being pumped. Install proper filtration of pump inlet plumbing. Excessive pressure and/or temperature of fluid being pumped. Check pressures and fluid inlet temperature; be sure they are within specified range. Improper installation of cups.
