Questions

1–10 of 103 Questions  
Sort by:

  1. how do you lower the pressure, by lowering motor rpms, nozzles or is their an adjustment on this unit somewhere, thx...

    1. Never adjust the unloader without having pressure gauges attached to your wand, so you can determine exactly what pressure your adjusting to, if not you could have a failure causing serious bodily injury or even death.

      Helpful?

    2. You can adjust the pressure on this NorthStar Pressure Washer by tightening or loosening the unloader valve found on the pump. You can also adjust by using different nozzle with a wider spray pattern for lower pressure, or narrower for higher pressure. The pump is designed to run only when the engine RPM at full throttle, and should never be run at lower RPM.

      Helpful?

    3. Typically by the red knob on the side of the pump but lowering the motor rpms will decrease the pressure. I would not recommend this procedure to operate.

      Helpful?

  2. is trailer highway rated & can be taged?

    1. This NorthStar hot water pressure washer and trailer is highway rated. We will send out separately a certificate of origin that can be used to get tags if your state requires them.

      Helpful?

    2. Yes it is. Around two weeks after purchase a title arrives in the mail ready to be taken to the courthouse to get your tag!

      Helpful?

    3. it can be tagged and should be fine for pulling on highway with no problem

      Helpful?

  3. Is there a drain valve on the water tank # 157595

    1. Yes there is a ball valve on the bottom of the tank

      Helpful?

    2. The tank on this pressure washer has a drain valve.

      Helpful?

  4. How is this item packed for shipping?

    1. The washer/trailer is shipped via freight. It comes with a light weight steel frame around the entire unit with the trailer tongue and tool box unattached. It took me about 45 minutes to an hour to unpack and assemble (using air tools)

      You will need a raised loading dock and forklift (with 48") forks to unload.

      Helpful?

    2. Our NorthStar Pressure Washer comes crated and will only need the tongue of the trailer installed along with the jack stand.

      Helpful?

  5. How long does it take for this unit to heat the water to at least 180 F?

    1. As soon as the water goes through the heater it is heated. I would say around 8 seconds to travel through the hose to the gun!

      Helpful?

    2. This NorthStar Hot Water Pressure Washer will have the water heated to 210 degrees in a matter of seconds. You may, when you first turn it on have some cold water, but almost instantaneously you will have water at 210 degrees.

      Helpful?

  6. are the hose reels self retracting or manual wind. Thanks

    1. Manual wind.

      Helpful?

    2. The hose reels that are included on this trailer are manual rewind.

      Helpful?

  7. On this unit can you change the pump to get more gallons per minute so i can clean driveways effectively with a surface cleaner.

    On this unit can you change the pump to get more gallons per minute so i can clean driveways effectively with a surface cleaner.

    Thanks, Roger

    1. you should not have to change the pump if you open the unloader all the way

      Helpful?

    2. With a hot pressure washer your cleaning efficiency is much higher than with a cold water unit. Also, most surface cleaners cannot handle the higher temperatures. The pump GPM cannot be altered.

      Helpful?

  8. Water Tank

    how long can you wash befor the water runs out on that 200 gallon tank

    1. This pressure washer provides 4 gallons per minute at 4000 psi. So if you were running at full pressure, you would have approximately 50 minutes of continuous washing on one full tank of water. It is possible to hook this unit up to a hose from an external water source for unlimited continuous use.

      Helpful?

    2. The pump on the pressure washer is a 4 GPM pump so:

      200 Gallons divided by 4 Gallons Per Minute (200/4) = 50 Minutes.

      50 minutes of spraying time.

      Helpful?

  9. Can this be sold/shipped to California? 

    1 answer

    1. The pressure washer is unable to be sold or shipped to the state of California.

      Helpful?

  10. What is the heating coils part number I need to replace it

    1 answer

    1. The heating coil, part #790017, can be purchased through our sister company, Jacks Small Engines. Please visit www.JacksSmallEngines.com for pricing and availability.
