Field cleaning of the sprayer from one job to the next is a good business practice and insures happy customers. Cleaning a sprayer in town requires containment of the spray materials to prevent contamination of local water supplies. The John Deere SprayMaster Power Washer, complete On-Board Hydraulic Powered High Pressure Wash System is designed to make short work of the cleaning process. With 4 gpm @ 1500 psi, 50 feet of high pressure hose, and a trigger gun with a 36'' lance, you can quickly clean the sprayer before it leaves the field. The generous 120 gallon on board water supply ensures uninterrupted cleaning. General Safety Information The following special attention notices are used to notify and advise the user of this product of procedures that may be dangerous to the user or result in damage to the product. NOTE: Notes are used to notify of installation, operation, or maintenance information that is important but not safety related. CAUTION: Caution is used to indicate the presence of a hazard, which will or can cause minor injury or property damage if the notice is ignored. WARNING: Warning denotes that a potential hazard exists and indicates procedures that must be followed exactly to either eliminate or reduce the hazard, and to avoid serious personal injury, or prevent future safety problems with the product. DANGER: Danger is used to indicate the presence of a hazard that will result in severe personal injury, death, or property damage if the notice is ignored. • Do not pump at pressures higher than the maximum recommended pressure. • Maximum liquid temperature is 140o F. for better packing and valve life when the water temperatures are above 110o F, a pressure feed system of 40 to 60 psi should be incorporated. • Release all pressure within the system before servicing any component. • The high-pressure gun and lance should be securely held by hand or in a holding device before the unit is started. Make sure the lance is not pointed toward any person or animal. Failure to do so could result in serious injury. • Periodically inspect the pump and the system components. Perform routine maintenance as required (see Repair Section). • Do not use these pumps for pumping water or other liquids for human or animal consumption. Start-up and Maintenance Before Starting Up • Check that the oil is at the correct level using the Dipstick, topping off if necessary (See Figure 1). Use a nondetergent, SAE 30 weight oil. FIGURE 1 Dipstick Location Dipstick • Change oil after 40 hours of break-in operation. Thereafter, change the oil every year or 500 hours, whichever comes first. NOTE: During warm months keep the power Washer Pump filled with water and the Outlet Pressure Hose and Gun Assembly attached. For storage during freezing conditions, flush the Pump with the specified John Deere Winterizing Fluid, N209391-CA (Canada) or N209318-US (U.S.). Leave this fluid in the Pump with the Outlet pressure hose and Gun attached. During Bypass Operation • When the water is diverted back to the pump inlet side, a temperature rise occurs. A thermal relief is included to keep the water temperature at a maximum of 145o F. Unloader Valve Safety Information • Maximum pressure is set at the factory and cannot be adjusted to a higher pressure. • Do not tamper with the unloader valve settings or with the locking ring; doing so will void the warranty. Damage to the pressure washer may result. WARNING: Water discharged from the thermal relief valve is hot (145o F). Operation 1. Check the water level in the rinse tank. Never operate the Pressure Wash Pump without a water supply. NOTE: Periodically check the Line Strainer and clean the Line Strainer if it is necessary (See Figure 2). 2. Open the water supply valve. CAUTION: Do not operate any other hydraulic functions on the 4700 while the Power Washer is in use. 3. Set the engine speed to 1,500 RPM. 4. Activate the Hydraulic Motor by placing the Lever on the Hydraulic Control Valve in the DOWN position (See Figure 3). 5. Point the Spray Gun at the target area and squeeze the Spray Gun Trigger (See Figure 4). 6. The standard Power Washer is equipped with an adjustable cleaning angle nozzle. The cleaning angle may be varied throughout its range by rotating the black outer body clockwise (CW) or counterclockwise (CCW). 7. If your Power Washer is equipped with the optional Detergent Injection System. The nozzle must be set in Low Pressure Mode to activate the injector and draw soap. For rinsing, the nozzle should be set in High pressure Mode. Pushing the black nozzle body forward places the nozzle in the Low Pressure Mode. Pulling the black nozzle body back places the nozzle in the High Pressure Mode. NOTE: When finished using the Power Washer, make sure the Power Washer is shut off (Hydraulic Control Valve lever in the UP position) before operating other hydraulic functions on the 4700 (See Figure 5). 8. Store all the Power Washer components in brackets provided for their storage. ...
