4000 PSI Pressure Washer Rental

Homeowners & professionals love this pressure washer because it produces a lot of pressure when you need it and less pressure when you don't. The adjustment control knob allows you to reduce the output from 4000 PSI to 500 PSI. A 50 foot section of high pressure hose comes with it. If you need to reach those remote locations around your house without relocating the machine then we recommend renting an extra 50 foot section of high pressure hose. It includes 40, 15 and 0 degree spray nozzles and since it is mounted on wheels, it can easily be rolled into remote locations around your home. This is a pull start machine so before reserving, please make sure you have enough arm and shoulder strength to pull the starter cord.

Questions & Answers

Is there a way to control the pressure and water output?

Yes, there is a control for reducing the amount of pressure and water that is released. This is controlled by a black knob near the pressure pump. Turning to the right will increase pressure and turning to the left will reduce pressure.

Does the pressure washer come with a garden hose?

No. You will need to ensure that you have an outdoor spigot and a normal garden hose.

How do the Nozzles Work?

0 - red nozzle: Narrow and powerful stream of water. Used for very difficult stains and caked mud. Do not use on decks or fences. 15 - yellow nozzle: Uses a small fan spray for a focused cleaning. Good for somewhat difficult to remove dirt and debis. 40 - white nozzle: Largest angle of spray used for cleaning surfaces quickly and for rinsing. 65 - soap (black) nozzle: Soap tip is used in conjunction with the cleaning fluid. This is the only nozzle that can be used with cleaning solutions.

Can I use a pressure washer on windows?

This is not recommended, but can be done if great care is taken. You must fold towels on the inside window ledge (after making sure windows are closed properly.) Do not use pressure washer on damaged windows! Use the 65 nozzle and stand at least 5 feet away from the house and use at a 45 angle.

Why can't chemical injection be used under high pressure?

Applying chemicals in low pressure has two advantages. First, if the chemicals were applied in high pressure, they will splash off, resulting in wasted solution. Secondly, because chemical injection only works in low pressure, you can change from low pressure to high pressure at the wand, instead of going back to the unit to engage chemical injection.

Can I use bleach in the pressure washer?

NO. You must NOT use any household bleach in the machine. Bleach will damage the seals and o-rings in the gun, wand, hoses and pumps.

Can I use water from a lake or pond?

NO. Water that is drawn from a lake or pond may contain debris that will clog the pump. Pumps are not designed to draw water from a stationary source.

How long can hoses be extended?

The recommended length is not usually more than 100 feet since pressure will decrease the longer the distance.


Locate your garden hose and connect it to a spigot on the outside of your house. Make sure you have good water flow when you turn on the spigot.

Clear away furniture, planting pots, BBQs, vehicles and any other objects that reside on the surfaces you plan to wash.

Pressure washing can be loud. You may want to give your neighbors advance notice about when you will be cleaning.

This pressure washer will use about 1 gallon of gasoline per hour. Be prepared with plenty of gas to finish your project.

Do's & Don'ts

DO: When unraveling the hose, carefully unwind any twists that are in the hose. This will prevent kinks from occurring in the hose.

DO: Ensure you have enough water pressure from your garden hose. This machine requires a strong and consistent flow of water from your spigot.

DON'T: Kink the high pressure hose. Purposefully or accidentally kinking the hose will ruin the high pressure hose.

DON'T: Let the machine run for more than about 1 minute without discharging water. The pressure washer pump is water cooled and uses the water moving through it to cool itself down. If you need to take a break from pressure washing for more than 1 minute then just turn the machine off.
