Theharmful elements may causeproperty damage or severeinjury.STEP 1: Connect the optional detergent injector todischarge nipple on machine. Connect high pressurehose to injector with quick coupler. (Check to makesure locking coupler sleeves are in proper positionbefore applying water pressure).STEP 2: Use detergent designedspecifically for pressure washers.Household detergents could damagethe pump. Prepare detergent solutionas required by manufacturer. Fill acontainer with pressure washer de-tergent. Place fi lter end of detergentsuction tube into detergent container.STEP 3: With safety latch on spray gun engaged,secure black detergent nozzle intoquick coupler. NOTE: Detergentcannot be applied using red, yellow,green or white nozzles.STEP 4: With the engine running,pull trigger to operate machine. Liquiddetergent is drawn into the machine and mixed withwater. Apply detergent to work area. Do not allowdetergent to dry on surface.IMPORTANT: You must flush the detergent injec-tion system after each use by placing the suctiontube into a bucket of clean water, then run the pres-sure washer in low pressure for 1-2 minutes.THERMAL PUMP PROTECTIONIf you run the engine on your pressure washer for 1-2minutes without pressing the trigger on the spray gun,circulating water in the pump can reach high tempera-tures. When the water reaches this temperature, thepump protector engages and cools the pump by dis-charging the warm water onto the ground. This thermaldevice prevents internal damage to the pump.CLEANING TIPSPre-rinse cleaning surface with fresh water. Place de-tergent suction tube directly into cleaning solution andapply to surface at low pressure (for best results, limityour work area to sections approximately 6 feet squareand always apply detergent from bottom to top). Allowdetergent to remain on surface 1-3 minutes. Do not al-low detergent to dry on surface. If surface appears tobe drying, simply wet down surface with fresh water.If needed, use brush to remove stubborn dirt. Rinseat high pressure from top to bottom in an even sweep-ing motion keeping the spray nozzle approximately1 foot from cleaning surface. Use overlapping strokesas you clean and rinse any surface. For best surfacecleaning action spray at a slight angle.Recommendations:• Before cleaning any surface, an inconspicuousarea should be cleaned to test spray pattern anddistance for maximum cleaning results.• If painted surfaces are peeling or chipping, useextreme caution as pressure washer may removethe loose paint from the surface.• Keep the spray nozzle a safe distance from thesurface you plan to clean. High pressure wash asmall area, then check the surface for damage. Ifno damage is found, continue to pressure wash-ing.CAUTION - Never use:• Bleach, chlorine products and other corrosivechemicals• Liquids containing solvents (i.e., paint thinner,gasoline, oils)• Tri-sodium phosphate products• Ammonia products• Acid-based productsThese chemicals will harm the machine and will dam-age the surface being cleaned.RINSINGIt will take a few seconds for the detergent to clear.Apply safety latch to spray gun.
