High pressure washers are important cleaning aides that can be used to clean out dirt, oil, grime and debris from cars and car parts, lawn mowing machines, driveways, parking lots, garages, etc. However, the cleaning efficiency of this cleaning equipment relies by a great extent on how well they are maintained. If you wish to keep your high pressure washer working at peak efficiency, here are some useful maintenance tips that you should follow before and after using the equipment.
What to do before each use
Here are guidelines you should following prior to using high pressure washers:
- If you own a fuel-powered model, make sure to check on the oil and fuel levels first; top up if the levels are low, but do not overfill as this will cause oil to stick and accumulate on the surface of the pressure washer. Letting fuel to flow out freely while you’re running the equipment can be extremely hazardous since the fuel is often highly flammable. Remember that oil with dark color is an indicator you should change the oil.
- Inspect the water inlet screen, which is usually located at the point where you connect the hose pipe. If the screen looks dirty or blocked, flush it with buckets of clear water. If it is damaged, you have to replace it. If your high pressure washer has an inline screen in the wand extension, ensure it isn’t clogged as well. Use clear water to clean it and, if required, replace a spoiled screen.
- Inspect the high-pressure hose to detect if any leaks, abrasions, cuts, or bloating of cover has occurred. Don’t attempt to repair the hose if it is damaged. Replace it in accordance with the specifications of the equipment manufacturer. Before connecting the hose to the pressure washer, flush it with clear water to ensure there are no obstructions that would hamper water flow inside the hose.
What to do after each use
Do the following once you are done using high pressure washers:
- Flush out the cleaning detergent from the equipment and run clear water through it for a couple of minutes.
- Turn off the engine and let the pressure washer cool. If you own a pressure washer that runs on electricity, disconnect it from the electrical power source. Then, halt the water supply.
- To release the pressure off the equipment, engage the trigger lock on the spray-gun; press and clench on the trigger until all water is ejected from the water supply line. Disconnect all removable components, e.g. hose pipes from the pump and the spray gun.
- Pull the recoil handle a couple of times to get rid of any water remaining in the equipment.
- Flush out any debris from the equipment and store it in a cool, dry place for future use.
