How to Take Care of Your High-Pressure WasherTracy Murray
If you’d like to extend the life of your pressure washer that has been exposed to mud, mold, grime, and graffiti, it’s important to take the necessary steps to maintain it between uses. Neglecting to do so can decrease its performance and shorten its lifespan.
Following proper routine maintenance instructions before and after each use will ensure your pressure washer continues to work optimally for many years.
High-Pressure Washer Maintenance
Carrying out routine maintenance will ensure that the pressure washer is reliable and secure. To make sure the machine is functioning correctly, these steps should be taken before and after each use.
Before pressure washing:
- Inspect the rubber seals at each end of your hose to make sure they are not worn down. If they are, it can cause leaking or even harm while in use. Therefore, it is important to change any o rings that are not in good condition before using the hose again.
- Ensure the pressure nozzle attached to the end of your wand is firmly attached.
- Never plug the pressure nozzle with debris, dirt, or anything else.
- Prior to using a gas pressure washer, verify that it has new gas and oil. If the gas has been in the tank for an extended time, mix in a stabilizer and fill it up with fresh gas.
- Inspect your spark plug for any signs of deterioration. A corroded spark plug can lead to difficulty when trying to start the engine, as well as decreased performance when in use. Replace corroded spark plugs prior to using.
- When the unit is in use, the spray nozzle should remain open to prevent excessive pressure from building up within the hose and causing potential damage.
- It is essential to not use a pressure washer without the proper amount of water, as an insufficient amount can cause the pressure to become too great.
After pressure washing:
- Prior to any maintenance or cleaning of the washer, make sure to turn off the power and unplug the unit from its power source, as this will help to avoid any potential harm or destruction.
- Find the inlet where the cleaning agents are inserted and ensure that it is properly washed with water, removing any traces of residue or grime. Make sure that the water that runs out is clear.
- Clean the interior of the pressure washer to stop any unexpected occurrences while it is running.
- Before putting away, make sure to remove any extra liquid. If not, it could potentially invite bugs, cause mold to form, and generate bacteria.
- Keep your pressure washer in a place that is protected from extreme weather conditions, such as sun, rain, or snow, and make sure that it is in an area that is not easily accessible to children.
Important Note: It is essential to adhere to the guidelines provided by the manufacturer when operating a pressure washer, and to take the necessary steps to properly maintain it in order to ensure the safety of yourself and those around you.
If you notice any damage to your pressure washer or the high-pressure hose, stop using it right away. Purchasing a new one is the best option, and attempting to fix the hose yourself should be avoided.
If the device is not functioning properly due to damage or too much use, take it to a repair center or buy a fresh one.
Preventative Maintenance of your High-Pressure Washer
Setting aside time to inspect and maintain your pressure washer and its components, both prior to and after each use, will help you prevent any issues that could arise and save on costs for spare parts and repairs. Consult the instructions that came with your specific pressure washer to ensure you are following the correct protocol.
Before Each Use
Step 1: Check the Oil
Check engine oil and fuel levels: It is suggested to fill both the oil and fuel if they are low, or replace the oil using the oil recommended by the manufacturer. Refer to the owner’s guide of the engine for guidance.
Check inflatable tires: Maintain the air pressure of your tires at the specified level or within a range of 15 to 25 PSI.
Step 2: Check Screens
Check water inlet screen: If the water is dirty or blocked, flush it out with clean water; if the screen and rubber washer are damaged, replace them with new ones..
Check in-line screen: If the water is not clear, rinse it out; if the screen or O-ring is broken, replace them with new ones.
Step 3: Inspection of Hoses and Couplings
Inspect high-pressure hose: If the hose is leaking, torn, worn away, sticking out, or the couplings are broken or loose, it should be replaced with a hose that can handle the maximum pressure of the pressure washer.
Inspect the tubing and filter of the cleaning detergent system; if they have become contaminated or blocked, take the necessary steps to ensure they are cleaned. Take a look at the tube to check for any holes or tears, and make sure it is securely attached to the barb. If the tube or siphon/filter has been compromised, replace it.
Test spray wand assembly: If there is a leak in the connections, substitute the O-rings. If the nozzles are blocked, clean them out or, if the original spray wand, adjustable nozzle, or spray tips are damaged, replace them.
Rinse out garden hose: Take out any unwanted material from the hose before connecting it to the pump’s intake port.
After Each Use
Step 4: Flush the Cleaning Detergent
Flush the cleaning detergent injection system: Allow uncontaminated water to flow through the system for two minutes prior to shutting down the engine.
Shut down the pressure washer: Turn off the motor and allow it to cool down. Shut off the water supply.
Step 5: Relieve Pressure in the System
Reduce the strain on the system by pressing and holding the trigger on the spray-gun until all the liquid inside the line is released. Unplug the hose connected to the pump and take apart the hose leading to the spray gun from the pump.
Get rid of any remaining liquid in the pump by yanking the recoil handle six times. A trickle of liquid will come out of the pump’s exit point.
