Pressure Washer Maintenance Tips

Why examine and clean your pressure washer before and after each use?

You should examine and clean your pressure washer to avoid performance problems and, of course, for to save money on parts and repairs.


Here are some helpful tips from the manuals we use to keep our pressure washers up to date:

1)      Check the engine oil and fuel levels. The oil level in pressure washers should be checked prior to each use and changed every 50 hours of use or once every season. Consult engine owner’s manual for instructions.

2)      Check tires for wear and check the tire pressure periodically with a tire gauge to make sure it is at the correct inflation pressure, fill with air when necessary.

3)      Check the water inlet screen for dirt and debris, rinse it with water or replace it if damaged.

4)      Check the in-line screen for dirt and debris, rinse it with water or replace it if damaged.

5)      Safety first.

a)      Inspect high-pressure hose: Replace if leaks, cuts, abrasions, or bulging of cover exists also if couplings are damaged or have movement. New hoses must exceed maximum pressure rating of your pressure washer.

b)      Examine cleaning detergent injection tube and filter: Clean if dirty or clogged. Examine tube for leaks or tears and make sure it fits tightly on barbed fitting. Replace tube or siphon/filter if either is damaged.

c)       Test spray wand assembly: Replace O-rings if connectors leak. Clean nozzle orifices if clogged or replace spray wand, adjustable nozzle, or spray tips if original parts are damaged.

d)      And last, rinse out garden hose: Flush debris from hose prior to attaching to pump inlet.

After each use complete the following:

1)      Flush the cleaning detergent injection system: Run clean water through the system for two minutes before stopping the engine.

2)      Shut down the pressure washer: Shut off engine and let it cool. Turn off water supply.

3)      Relieve the pressure in the system: Press and hold spray-gun trigger until all water remaining in the line is expelled.

4)      Disconnect high-pressure and garden hoses from pump, and detach high-pressure hose from spray gun.

5)      Empty pump of remaining liquids: Pull the recoil handle six times. A small amount of water will leak from the pump’s water outlet.

And, one important tip:

During the off season when your pressure washer is being stored, the fuel should either be drained from the pressure washer or a fuel stabilizer should be added to prevent clogs in the carburetor. So when it is time to use the machine less time you need to prep it.
