How To Change Oil In Pressure Washer? Complete Step-by-Step Guide

What is the proper procedure for changing the oil in a power washer? The first step in performing an oil change is reviewing your owner’s manual. Simply remove the old oil and install a new one. To complete the work, gather the necessary supplies and tools.

This little fix will spare you a slew of hassles down the road. However, if you do it on time, you’ll help keep your pressure washer pump in good working order. Plus, you’ll be covered by a warranty. As a result, devote more time to keeping the pump in good working order.

Do You Need to Change Your Pressure Washer Pump Oil?

It all relies on the sort of pump you have in your pressure washer. Pressure washers that cost less than $400 typically don’t need pump maintenance. However, it’s always a good idea to consult your manufacturer’s instructions.

A wobbling pump or axial piston pump will tell you whether you don’t need to change your pump’s oil. These are normally pre-filled with oil and then permanently sealed, making it impossible to perform an oil change even if you wanted to.

Other pumps, on the other hand, are in desperate need of an oil change. If your owner’s handbook specifies that you should perform routine oil changes or if your oil pump has a drain and fill plug, you should perform the oil change yourself.

Your pressure washer will benefit greatly if you keep up with regular oil changes, such as:

• Oil is needed to alleviate the wear and tear, friction, and heating of the moving elements of pumping mechanisms. These parts can be protected against early failure by using oil.
• It has the added benefit of lowering the risk of overheating. As the seals expand in response to heat, the chance of cracking goes up.
• Your warranty may be voided if you fail to perform regular oil changes.

It’s best to follow this advice if your pump requires manual oil changes.

How to Change Pressure Washer Pump Oil

Let’s talk about the best way to change the oil in your pressure washer pump.

What You Need

What do you use for catching the spilled oil? Alternatively, you can use an oil pan or an old tray.

The bolt access can be opened with a wrench. Instead of a bolt, your pressure washer may feature a plastic knob.

A funnel for filling the pump with oil is needed.

A container for storing oil.

Using the manufacturer’s recommended amount of oil.

Clothes to clean with.

It is possible to use an oil drain stopper, suction cannon, or electric/manual pump.

Step by Step Instructions

1. Purge the Pump

Remove the wand from the spray gun and turn on the water supply. Pressure wash for two minutes with the engine running to remove any remaining water and grime. Pressure washers are more effective when they are heated up, which aids in removing dirt more quickly.

2. Drain the Oil

Finally, drain the engine’s oil and gas. As a first step, you’ll need to loosen and remove the reservoir top access bolt—or unscrew the knob. This is when your wrench comes in handy if you have a bolt to work with.

Oil can be removed in four ways. An oil drain plug is used to remove it from the pan’s bottom. You can also use a suction gun to remove it. You can also use a manual or electric pump to remove the waste.

Just tilt the pressure washer in either direction to pour the used oil into your container.

Prepare an oil pan or an old tray in case you need to use one of the other options.

3. Store the Oil

Set your oil storage container aside for now after you’ve emptied the old oil. This waste must be disposed of in accordance with local laws. The drain bolt or knob can now be reinstalled.

4. Add New Oil

Be sure to read the manufacturer’s instructions before attempting to use our technique, since they will differ based on the pressure washer and pump you own. Pre-measured pump oil bottles are available on some models.

You should always use a non-detergent pump oil in general. Make sure that the pump is about three-quarters filled of oil by using your funnel.

5. Close Up the Pump

It’s time to reinstall the bolt and retighten it. Wipe up any oil that has gotten on the cap or in the immediate vicinity using a rag. Make sure your pressure washer is in the upright position before you begin cleaning. Pressure washers can be used again after a few minutes.

Recommendation

In order to comply with local laws, you must properly dispose of the used rags.
