If you’re running a mobile pressure washer business, it’s extremely important that you know the components so you can troubleshoot in the field while staying online with the equipment manufacturer’s or supplier’s help desk. Most problems encountered on the job can be easily fixed so you don’t lose money in the field.

Your engine has a single crankshaft where all the power goes. In a car, this crankshaft goes to a transmission. On your machine there is a circular pulley pressed or wedged into the crankshaft. The pulley has two grooves. A car has a pulley at the front of the engine block between the engine and the radiator also with grooves. One goes to an alternator and one goes to a water pump.

The alternator produces electricity and keeps your car’s battery charged; same in the pressure washing unit. The water pump pumps water into the engine block from the radiator to prevent the car from overheating. It does this by using belts connected to these pulleys. It is relatively simple. If you look under the hood of your car, you will see it. On your machine, your motor also has belts attached to the pulley. One goes to the generator. The generator produces electricity and feeds:

The blower burner for heating water.

The spark to ignite the fuel to heat the water.

The emptiness in your truck

Your machine lights for night work

The 110-volt outlet on your machine for your work lights and recovery equipment

The pump, on the other hand, pushes the water from the pump through the hose and then through a pin-sized hole at the end of the gun, giving you incredible force from your sprayer.

It is important that you understand that, in all its complexity, the system is relatively simple and you need to understand each component and how it works. Reread this while looking at our team, think about it.
