Important Safety Instructions WARNING - Risk of Injection or Injury to Persons - Do Not Direct Discharge Stream at Persons. Do not use a hose if exterior damage is evident. - Risk of explosion. - Do not spray flammable liquids. - Do not operate in a flammable environment. CAUTION - Gun kicks back. Hold with both hands. - To reduce the risk of injury, read operating instructions carefully before use. WARNING - When using this product basic precautions should always be followed, including the following: 1.
Grounding Instructions Your product must be grounded. If your product should malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electrical shock. Your product should be equipped with a cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Operation Instructions Water Supply 1.) Make sure the water supply is clean. Debris can cause excess pump wear and reduce performance. 2.) An insufficient water supply will damage your pump. Make sure the water supply is steady and is 20% over the rated flow of your pump. Use a stopwatch to time how long it takes to fill a 5-gallon bucket with your garden hose. The bucket must fill faster than the times listed in the table below.
Operation Instructions Applying Chemicals 1.) Install the black nozzle when applying chemicals onto the cleaning surface. 2.) Start the pressure washer according to the start-up instructions. 3.) Submerge the chemical hose in cleaning solution. (See Pump Component Identification section for chemical injector location.) 4.) Squeeze the spray gun trigger. The chemical injector will draw the chemical into the water stream. 5.) Apply chemicals evenly onto the cleaning surface.
Maintenance and Storage Maintenance Mode Before performing any maintenance on the pressure washer, it must be placed in maintenance mode. 1.) Turn off motor and unplug cord. 2.) Turn off water supply. 3.) Squeeze trigger to relieve system pressure. Maintenance Schedule What to Check Inlet Filter When to Check Each Use Pressure Hose Each Use Bolts Pump Oil Each Use After 1st 50hrs, then 3mo/500hr What to Do Visually inspect and clean inlet filter with clear water.
Maintenance and Storage Pump Oil Change 1.) Place a suitable container below the pump to catch the used oil, then remove the oil fill cap and oil drain plug. 2.) Allow the used oil to drain completely, then reinstall the drain plug and tighten securely. 3.) Please dispose of used oil in a manner that is compatible with the environment. We suggest you take used oil in a sealed container to your local recycling center or service station for reclamation.
Maintenance and Storage Winter Storage Protect your pump, hose and gun from freezing. Items needed: 12” piece of garden hose or equivalent, funnel and RV antifreeze (approximately 6 oz.) 1.) Follow the storage instructions listed above. 2.) Make sure the motor start switch is OFF. 3.) Attach the garden hose with funnel to the pump inlet (see illustration). 4.) Pour RV antifreeze into the funnel, run motor until antifreeze comes out the pump outlet. 5.) Drain all water from the high-pressure hose.
Troubleshooting Problem Solution Motor will not start Low/Surging pressure or no water flow No chemical injection SOLUTION: A,B SOLUTION: C,D,E,F,G,H SOLUTION: I,J,K,L Cause Solution A- Tripped GFCI cord B- Tripped motor relay C- Insufficient water supply D- Plugged pump inlet filter E- Wrong nozzle F- Plugged nozzle G- Worn nozzle H- Leak in pressure hose I- Wrong nozzle J- Back pressure from extra long discharge hose K- Leak in chemical siphon hose L- Chemical strainer not submerged Reset GFCI cord
