Frequently Asked Questions - SuperPro SRC5040141E Simpson

How to purge air from the pump before starting the engine?
Turn on the cold water supply, point the gun in a safe direction, then hold the trigger for at least 30 seconds until water flows steadily. This removes air from the pump and hoses. Never start the engine without water in the pump.
What engine oil to use and how to check the level?
Use SAE 15W-40 oil or SIMPSON Premium oil. Check the level with the dipstick: insert clean dipstick into the tube without screwing, then remove. The level should be between min and max marks. The engine is shipped without oil, fill before first use.
How to start the engine correctly?
Follow the checklist: check oil, fuel, water connections, purge air. Set the throttle to RUN, pull the choke for a cold engine. For electric start, turn key to START for up to 5 seconds. For manual start, pull slowly until resistance then pull quickly. Gradually release the choke.
What to do if the output pressure is low or zero?
First check that the water source provides at least 8 GPM at 20 PSI. Purge air from the pump. Clean the nozzle (use the included cleaning tool) and the water inlet filter. Make sure the engine choke is in RUN position, not CHOKE. If the high-pressure hose exceeds 100 feet, shorten it.
How to use detergent with this pressure washer?
Attach the detergent hose to the pump, place the filtered end into detergent, install the black nozzle (low pressure). To rinse, place the hose in clean water and squeeze the trigger until clear water comes out. Do not let detergent dry in the pump.
How to maintain the pump after use?
Drain pump oil after the first 50 hours, then every 100 hours. Use SIMPSON Premium oil or SAE 15W-40. Clean the nozzle and inlet filter regularly. Before winter storage, use SIMPSON pump protection to prevent freezing.
What are the essential safety precautions?
Always wear safety goggles, gloves, and closed-toe shoes. Never point the spray at people or animals. Keep children and pets away. Use only outdoors in a well-ventilated area to avoid carbon monoxide poisoning. Do not touch hot engine surfaces.
How to store the pressure washer for more than two months?
Drain all fuel from the tank, lines, and carburetor. Change the engine oil. Remove the spark plug, pour 15 ml of new oil into the cylinder, then reinstall the spark plug. Disconnect the battery and store it in a warm place. Use SIMPSON pump protection to protect the pump from freezing.
What type of fuel to use and why avoid high ethanol?
Use clean, fresh unleaded gasoline with a minimum octane rating of 87. Do not exceed 10% ethanol (E10). E15, E20, and E85 can damage the engine. Do not use gasoline older than 30 days to avoid deposits.
How to contact customer service or make a warranty claim?
Call 1-833-FNA-RENT (833-362-7368) or email warranty@fna-group.com. Keep your proof of purchase and model and serial numbers. Do not return the product to the store. Normal wear parts (seals, valves) are not covered.

Terms

  • PSI - Pounds per square inch (PSI) is the unit to measure the pressure of water. In relation to a pressure washer, the higher the PSI number, the greater the pressure and stripping power produced.
  • GPM - Gallons per minute (GPM) is the flow rate of water. In relation to a pressure washer, the greater the GPM, the greater the flow or rinsing power produced.
  • CU - Cleaning units express the efficiency of the pressure washer. Cleaning units are calculated by multiply the PSI by the GPM. The higher the CU, the more efficient the pressure washer.

Preparation

  • Read all warning and instructions in this and all manuals that came with the pressure washer.
  • Remove all toys, bikes, lawn furniture, etc. from the work area if they are not to be cleaned.
  • Sweep any loose dirt and debris from the surface you will be pressure washing.
  • Cover nearby plants to avoid damaging them with the pressure washer spray.
  • Use caution when spraying windows. Always use the white, 40^ nozzle and stay at least 4 feet away.
  • Lay tarps down to collect paint chips and other debris blown off by the spray. Exterior paints used before 1977 may contain lead and will produce chips that will need to be collected and disposed of at a hazardous waste facility.
  • To minimize water infiltration to the pressure washer motor, locate the pressure washer as far as possible from the cleaning site during operation.

Pressure Washing

  • A wider spray equals faster cleaning, while a tighter spray equals deeper cleaning.
  • Keep the nozzle about 4 feet away from siding to avoid damage.

  • Start washing siding at the bottom and work your way up, then rinse from the top down.

  • Avoid driving water up behind siding.

  • Use overlapping strokes for even cleaning.
    Work in small areas to keep the soap from drying.

  • Do not aim the nozzle straight at the surface. Hold the wand at a 45^ angle to the surface at a distance that cleans well without causing damage.

Adjusting Surface Pressure

  • Back away from the surface to be cleaned. The further you position the nozzle from the surface to be cleaned, the lower the pressure to reach the surface.
  • Change to the white, 40^ nozzle. This nozzle produces a lower pressure, wider width spray.
