One should always keep in mind the directions on installing pressure washer parts. A pressure washer is utilized to eliminate traces of dust, dirt, molds, and other unwanted substances from sticking to building, vehicle, or road surfaces. Before attempting to install a pressure washer, one should first get to know its parts.

A standard pressure washer has three parts, namely the pump motor, high pressure hose, and a triggering mechanism. The pump motor builds up enough pressure for the trigger gun to transmit to the hose. High pressure is achieved by providing adequate water supply to the pump motor.

The triggering mechanism forces the high pressure water out of the hose with enough velocity to pierce through flesh and even pulverize asphalt. Different hoses are utilized for different cleaning purposes. Some hoses have a triangular-ejection nozzle, while others have a thin-release nozzle. Take note of these helpful tips when it comes to installing a pressure washer.

Step 1 - Determine Which Type of Pressure Washer to Use

First, identify which type of pressure washer is perfect for the cleaning job. If it will be used as an industrial cleaner or grease stripper, or cleaning heavy machinery, the gas-powered pressure washer should be utilized. The gas-powered type can provide maximum pressure needed for industrial cleaning.

Because the substances that need to be removed include oil, grease, detergent residue, and hard-sticking chemicals, high pressure is needed for successful cleaning. Also consider if the pressure washer needs to be moved often, since the electric-powered type loses on mobility because it needs an electric outlet to operate.

For indoor cleaning which includes only dust removal, an electric-powered pressure washer should be utilized. There are three main divisions in the pressure washer: the crankcase, which stands for the engine housing, the pumping section, where water is processed, and lastly, the hose and nozzle.

Step 2 - Check the Water Pump

Make sure the pressure washer’s parts are complete and compatible with one another. The first major part, the water pump, comes in two types: the belt-drive and direct-drive pump systems. The belt-drive system is more complex, and has additional parts such as pulleys, belts, and gear box.

The direct-drive system, on the other hand, is fused directly to the engine. There are three sub-types of the water pump, namely the axial, wobble, and camshaft pump. The axial pump operates by employing an oil storage compartment, large bearings, and cylinders.

The wobble-type operates like the axial pump, except that it does not have a storage compartment, and has smaller bearings and cylinders. The axial pump has many connecting rods, and utilizes pistons similar to those of a car engine’s. Each type and sub-type of water pump has specific manufacturer’s instructions on how to install it to the engine.

Step 3 - Check the Hose and Nozzle Configuration

Once the triggering mechanism has been attached to the water pump and engine system, it’s time to check on the hose and nozzle configuration. Make sure the hose and nozzle are attached securely to the triggering mechanism. A loosely fit hose can result in permanent machine damage. As mentioned earlier, there are many types of nozzles. It’s important to know how the pressure washer will be used in order to choose the perfect nozzle for the job.

Step 4 - Do a Test Run of the Newly Assembled Pressure Washer

Before actual application, test the pressure washer first by turning it on and aiming the hose and nozzle to the ground. This will determine if the pressure washer is configured properly, and if it releases the desired amount of pressure.
