Pressure Washer Maintenance Tips (Pt. 2)

In the continuation of this series, we will consider other required maintenance items as well as tips for long-term storage.

Other Regular Maintenance Items to Consider

• Clearing spray tip of clogs.

• Lubricating connection (hose, spray gun, and wand extension)

• Replace O-rings (water-inlet, high-pressure hose, spray gun connections)

• Remove refuse from cooling vents

• Check muffler and spark arrestor (your pressure washer may or may not have these)

Engine Maintenance Tips for Gasoline-Powered Pressure Washers

Be sure to check your owner’s manual for maintenance specific to your pressure washer.
For the following tips be sure you have first disconnected the spark plug wire from the spark plug and position it away from the plug. Perform the following in a space with good air circulation.

• Spark plug: Clean off the area surrounding the plug so no debris will enter the combustion chamber when the plug is removed. Check the plug for cracks, burns, or pits. Check the electrode gap using a gap tool or feeler gauge to adjust it as needed.

• Oil change: Drain the oil while it is warm. Refill with manufacturer-approved oil being careful not to go over the max level line. Recycle according to your area’s system.

• Air filter: If your filter is paper it will need to be replaced. If your filter is reusable, check your manual for specific instructions.

• Fuel system: Check your owner’s manual to see what type of fuel and fuel additives are suggested. Gas that is purchased at the pump will degrade in time and cause issues in the engine so be sure the gasoline you use is no more than 30 days old. If you are concerned about this use an Ethanol-free, premixed fuel.

Don’t forget to reconnect the spark plug after these maintenance procedures.

Storage Tips

If your pressure washer will not be used for more than 30 days, you will need to prep it for storage. Check your manuals for specifics but here are a few general tips.

• Be sure you have completed the “After Use” maintenance tips mentioned in part one of this series.

• If your pressure washer is gasoline-powered and the fuel is not treated with a stabilizer, it will need to be drained into a safe container. Run the washer in a well-ventilated area until the fuel is completely used, and the machine stops running. Dispose of the gasoline according to local regulations

• Choose a dry place to store the machine. A location that will not freeze or be subjected to heat that may dry the pump seals or ignite any remaining fumes from the fuel.

• Find a good pump lubricant/antifreeze and lubricate the seals and pistons.

• Use a cover that will not seal in moisture.
