Read carefully before attempting to assemble, install, operate or maintain the product described. Protect yourself and others by observing all safety information. Failure to comply with instructions could result in personal injury and/or property damage! Retain instructions for future reference. Description Plunger Pumps are designed for a wide variety of high pressure washing applications. They are constructed with die-cast bodies and feature a brass head. Internal components include special thick solid ceramic plungers for long life and durability. Precision cast cooling fins are anodized for maximum heat dissipation. Oversized needle bearings on the drive side, and ball on the non-drive side together with the precision supports assure positive alignment and centering in relation to the crankcase. Valve cages of special designed Ultra-Form provide positive seating and extended life. Ball bearings on both sides of solid shaft drive pumps. One-piece connecting rods are special alloy aluminum, oversized for strength and load disbursement. These pumps are designed for, belt drive, or coupling drive systems driven by electric motor or gasoline driven systems, electric motor direct drive systems, and gasoline engine direct drive systems.

Operating Instructions and Parts Manual Plunger Pumps General Safety Information (continued) Maximum water temperature is 140°F. All positive displacement plunger pumps must have a safety relief valve installed on the discharge side of the pump, this valve could be either an unloader or regulator and must be of adequate flow and pressure for the pump. Adequate protective guards must cover all moving parts. Perform routine maintenance on the pump and components. Use only components that are rated for the flow and pressure of the pump, this would include hose, fittings, safety valves, spray...

Operating Instructions and Parts Manual Plunger Pumps Installation (continued) BELT DRIVE SYSTEMS 1. Mount the pump securely to the base plate. (See Figure 10) For new installation a Figure 10 mounting rail kit is required, refer to parts breakdown. 2. Install the pump pulley on the crankshaft. It should be as far onto the shaft as possible. 3. Align the pulleys so they are in line. (See Figure 11) 4. Use a belt tension gauge to assure proper tension (too much tension can cause bearing failure or damage the belts as well as cause other problems). (See Figure 12) 5. Installation complete....

Operating Instructions and Parts Manual Plunger Pumps Service Pumps (continued) DISASSEMBLY 1. First remove the eight 5mm head bolts. 2. Place the screwdrivers as shown between the head and crankcase of the pump, lifting one up and the other down. The head should start to lift off of the plungers. (See Figure 17 Figure 17) 3. When you remove the head you may notice that some of the water seals have stayed on the plungers and some in the head. To remove the seals from the plungers simple turn the assemblies and pull off. Figure 18 (See Figure 18) 4. If the seal assemblies are in the head use...

Squarely seat the retainer into the head and push with even pressure until it snaps into Figure 25 position. (See Figure 25) 3. Twist and pull the plunger off the plunger rod. (See Figure 28) 4. Remove the plunger rod O-ring seal with the mechanics pick. 5. Remove the brass slinger. At this point clean any thread locker that is left on the plunger rod and retaining nut threads. If the plungers are not damaged they do not need any servicing. 1. Install the brass slinger washer....

(See Figure 32) 3. Torque the head bolt as shown in the tightening sequence diagram. (See Figure 33 & 34) (See Table D or parts breakdown) Figure 33 OIL CHANGE Change oil after first 50 hours of use. Then every 500 hours. Refer to parts breakdown for oil type. WINTER OR LONG TIME STORAGE 1. Drain all of the water out of the pump. 2. Run a 50% solution of a RV or non-toxic/biodegradable antifreeze through...
