What Does Our Inspection Include?

Protecting your investment means maintaining your equipment. To extend the life of your equipment it’s important to schedule regular maintenance. Our technicians work closely with our clients to educate and inform you on the proper procedures of maintaining your equipment. Performing the correct start up and shut down procedures will extend the life of your equipment. Have a question regarding maintenance please reply to our contact us page with your inquiries. We have weekly, monthly and quarterly scheduled maintenance programs to ensure your equipment performs to your satisfaction. Please refer to our tips and  tricks before scheduling an appointment to prevent unnecessary service calls.

  • Check pump pressure

No pressure or low water pressure can be the result of a restriction on the pumping system that could cause pump cavitation. Pump cavitation can prematurely wear components on a pressure washer. Too much pressure can result in damaging components caused by improper adjustments. This can also damage the machine or cause injury to the operator.

  • Check pump volume

Low water volume can indicate a problem with the pumping system. This can be caused by a faulty component or a plumbing issue.

  • Check nozzle damage

The orifice size of a nozzle creates the water pressure intensity. When the nozzle orifice starts to wear, it reduces the cleaning units by lowering the pounds per square inch (PSI) of your pressure washer.

  • Check belt tension

Belt tension is required to maintain adequate pressure and volume of the pumping system. When belts are worn, cracked or loosen it can cause premature wear and performance complications

  • Check pump oil

Pump oil lubricates the pump and prevents premature failure of the pump components. Low oil can cause overheating and failure of the pumping system. HPS advises that you change the pump oil after the first 50 hours of use and every 250 hours after the first oil change.

  • Check engine oil

Engine oil lubricates the engine components. Low oil levels could cause the oil to overheat, break down, or seize the engine. HPS advises that you change the engine oil after the first 50 hours of use and every 250-350 hours after the first oil change.

  • Check hoses for signs of wear

High pressure hoses can overtime become damaged and worn. Check hoses and crimps for signs or wear. Our hoses contain a metal braid and can be seen when the hose starts to wear through. This is an indication that a new hose is required to prevent further damage or injury to the operator.

  • Check trigger guns & wands

Trigger guns and wands should be inspected regularly to provide optimal performance and a safe environment for the opterater.

  • Check quick couplers

Quick connects provide easy access to remove and connect nozzles, hoses and guns. Quick Couplers are wear items and should be inspected regularly to prevent leaks or damage to the machine.

  • Check injectors & soap metering valve

Soap metering valves and injectors provide the proper dilution ratio for a enhanced cleaning performance. Ensure that soap valves are closed when not in use to prevent air from getting into the pumping system.

  • Check coils for damage

Heater coils overtime can create mineral deposits causing scale build up in the coil. This can damage the pump and its components. Cooling the coil down is a great way to prolong the longevity of the coil and minimize scale build up.

  • Check for coil soot

A burners exhaust can create soot deposits on the outside of the heating coil from fuel, air or gas pressure changes. Soot is a sign of a combustion problem and can result in a dirty exhaust. It is best to address this problem sooner than later as it can cause future repairs.

  • Check unloader adjustment

NEVER, tamper with the unloader. The unloader valve is set to factory standards to limit the pressure when the trigger gun is engaged and disengaged. Adjusting the unloader can damage components and create thermal shock in the system by having too high of a spike pressure.

  • Check electrical connections

A loose wire or connection can create a voltage drop in the electrical system. This can create an increase in the amperage draw causing a switch, motor, transformer, relay or other components to overheat and fail.

  • Check burner thermostat

Thermostats turns the burner ON and Off, which then allows the operator to set the correct temperature for their cleaning application. A malfunctioning thermostat can result in overheating and damage to the system.

  • Check Voltage & Amperage

Loose wires and connections can affect performance and operation.

  • Check oil or gas burner for wear or corrosion

This ensures the burner is performing up to factory specifications.

  • Check for contaminated or stale fuel

When fuel sits for long periods of time it can become stale as well as create condensation in the fuel tank. Water and other contaminants can cause damage to the fuel components and affect the overall performance.

  • Check fuel filter

Fuel filters filter out debris, contaminants and water after the fuel tank. Cleaning and changing the fuel filter can prevent future damage. HPS recommends fuel filters be changed in the first 50 hrs and everything 350 hours after the first change.

  • Check fuel or gas pressure

If the fuel pressure changes, the amount of fuel supplied to the combustion chamber will also change causing the burner to burn incorrectly. The fuel or gas pressure affects the air and fuel mixture of the burner resulting in an inconsistent burn. This can cause soot to build up and damage other components.

  • Check burner combustion

The air and fuel mixture should be checked regularly for optimal performance.

  • Check engine air filter

A dirty air filter may reduce the engine performance and the performance of the pressure washer. Clean or replace the air filter as necessary.

  • Check engine spark plugs

Spark plugs should be inspected and replaced when worn.

  • Check engine fuel filter

The engines fuel filter should be inspected for debris or contaminants and replaced when needed.
