Read carefully before attempting to assemble, install,operate or maintain the product described. Protect yourself and others by observing all safetyinformation. Failure to comply with instructions could result in personal injury and/or propertydamage! Retain instructions for future reference.DescriptionPlunger Pumps are designed for a wide variety of highpressure washing applications. They are constructedwith die-cast bodies and feature a brass head. Internalcomponents include coated ceramic plungers for long lifeand durability. Precision cast cooling fins are anodized formaximum heat dissipation. Oversized needle bearings on thedrive side, and ball on the non-drive side together with theprecision supports assure positive alignment and centeringin relation to the crankcase. Valve cages of special designedUltra-Form provide positive seating and extended life. Onepiece connecting rods are special alloy aluminum, bronzerods over 4,000 psi units, oversized for strength and loaddisbursement. These pumps are designed for gasoline drivensystems.Figure 1Hollow ShaftFigure 2Hollow ShaftRSV 3400 rpm D Version - 3/4”ModelMax GPM Max PSIRSV2.5G25D-F252.52500RSV3G25D-F2532500RSV 3400 rpm D Version - 1”ModelMax GPM Max F4043000RSV4G40D-F4044000NORTHAMERICAForm RSV-OM 0607First ChoiceWhen QualityMattersHighPerformancePumps

RSV Series PumpsOperating Instructions and Parts ManualPlunger PumpsGeneral Safety Information(continued)Maximum water temperature is140 F.All positive displacement plungerpumps must have a safety relief valveinstalled on the discharge side of thepump, this valve could be either anunloader or regulator and must be ofadequate flow and pressure for thepump.Adequate protective guards mustcover all moving parts. Performroutine maintenance on the pump andcomponents.Use only components that are ratedfor the flow and pressure of the pump,this would include hose, fittings, safetyvalves, spray guns etc.Electric Drive PumpsYour power supply must conform to thesystem requirements.The motor must be grounded. UseGFCI plugs and receivers.Do not handle the pump/motor withwet hands.Only use power cords that are ingood condition.Never pull the unit by the powercord.Never spray or clean the unit with waterFailure to follow these warningsmay result in personal injury ordamage to property.InstallationDirect Drive Gasoline Pumps1. Install theshaft key into thekeyway and applya light coating ofanti-seize on theengine shaft. (SeeFigure 3)Figure 32. Align the two key waysand push the pump completelyonto the engine.3. Install all four (4) bolts and tightenevenly.4. Remove the redshipping oil cap andinstall the blackcrankcase vent cap.(See Figure 4)Figure 45. Install the appropriateunloader valve and otheraccessories.6. Install the appropriate water inletand discharge fittings.7. Connect the water supply hose andhigh-pressure discharge hose/spraygun.8. Turn on the water supply.9. Open the spray gun to purge thesystem of any air.10. Start the engine.11. Adjust the engine speed andunloader valve.Winter or Long Time Storage1.Drain all of the water out of thepump.2.Run a 50% solution of a RV ornon-toxic/biodegradable antifreezeNORTHAMERICAFirst Choice When Quality Matters

(See Figure 7)Inspect the valve o-ringfor any damage, replaceif necessary.Figure 6Figure 7Servicing the ValvesDischarge Valve Assembly:The inlet and discharge valves in thisseries pumps are all the same. Thevalves are located under the six 19mmhex plugs. The inlet valves are locatedon the inside portion of the head underthe seal assemblies and the dischargevalves are located on the top row of thepump head.1.Tools required: #8-32x” machine screwand diagonal pliers, screw driver, 19mmsocket, ratchet, and torque wrench.3.Discharge ValveRemoval:1.Remove the valvecap. (See Figure 5)2.Inspect the valvecap O-ring for anydamage, replace ifnecessary.3.Insert the valveassembly squarelyinto the portpushing it into placewith a deap wellsocket (you will feelthe valve assemblyseat).
