And before you get distracted by the next bright shiny object to cross your path, be sure to replace the drain plug before re-filling the pump with oil. Using a makeshift funnel or large diameter plastic tubing can help you “aim” the oil into the correct container. Secure the oil fill cap and you're done!ĭraining the oil through the drain plug at the bottom of the unit is a quick way to do a pump oil change, not counting the clean-up (if you do make a mess, an oil stain remover may come in handy). Now it is safe to fill the pump using the oil fill opening. Used motor oil never wears out, so why throw it out? 2 Put the used oil in a container so that it can be brought to a recycling facility to be cleaned and reused.Pump it out, using a hand-operated or electrical suction pump Extract the oil from the pump using one of three methods:ĭrain it from the bottom of the oil pan using the oil drain plug.A word of caution: the unit may be hot to the touch so use caution when removing the drain plug. The reason is warm oil traps the dirt better and flows much quicker than cold oil. Run the machine for a few minutes or perform the pump oil change at the end of using the pump.The basic procedure is the same regardless of how the oil is extracted

There are several methods for removing oil during a pump oil change and these are explained in more detail below. Check your pressure washer manual to make sure you are using the right oil. 1 It is important to use a non-detergent oil in this setting because using an oil with a cleaner (detergent) will foam up when it is agitated by the dippers. This is a process that includes rotating “dippers” that throw oil into the pistons and cylinders. This is because most pressure washer pumps use splash lubrication. Most pressure washer pumps use a 30w non-detergent oil. You’ll get the most out of your hard working machines when you take care of them. When clean oil flows through a pressure washer pump, you will extend its working life (new pressure washers don’t come cheap) and optimize its performance. There are many benefits to regularly changing the oil and the most obvious is clean oil keeps a machine lubricated and running properly.

The purpose of the pump is to produce the water pressure which enables you to do the task at hand. The high pressure pump inside a hard working pressure washer is literally the heart of the machine. A pump oil change should be done every 3 to 5 months to keep equipment running smoothly, safely and efficiently.
