How to Change the Oil
Performing an oil change is a simple process but also check on the washer’s manual to confirm you’re doing the right thing. First, get all the necessary tools to complete the task just in case it gets messy.
Start by removing any contaminants by purging the pump, turn on the water then remove the wand from the spray gun. Turn on the engine until you get a constant stream of water, which should be for about two minutes.
The pump is now ready, but don’t forget to get rid of the old oil by draining it from the engine. With your gloves on, remove the cap and have a drain pan ready to hold the expelled oil. It’s advisable to tilt the machine so that every drop gets eliminated.
The pump is ready for the new oil but always confirms the correct oil type and amount to put. Fill the reservoir with the right amount of the oil, as less or excess amount can negatively affect the washer. Reinstall the cap once done and ensure that you wipe any messed-oil around the lid and dispose of the old oil.

Do the oil change as per the instruction manual. Also, at the end of the winter period, oil refill is essential since it tends to thicken.
