Quick answer
Beginner or not, you can apply these pointers to have your pressure washer up and running in no time!
Since there are two types of pressure washers: electric and gas, we’ll touch on each:
How to start an electric pressure washer:
- Start with a clean inlet filter.
- Attach the necessary hoses to the pump. (e.g., garden hose, high-pressure hose)
- Attach the right nozzle for the task.
- Turn on the water after connecting the hoses.
- Pull the trigger to release all of the air and only let the water run out of it.
- Plug into an outlet.
- Turn on the machine.
How to start a gas pressure washer:
- Start with a clean filter.
- Attach the necessary hoses to the pump. (e.g., garden hose, high-pressure hose)
- Attach the right nozzle for the task.
- Turn on the water.
- Pull the trigger to release the pressure and only let the water run out of it.
- Check the fuel and oil levels.
- Turn all the necessary switches to the “On” or “Open” position.
- Switch the machine to the “On” position, then pull the chord.
- Turn the choke to the “Off” or “Close” position.
Whatever machine you use, the method applied is very similar.
The difference is that the gas pressure washers have additional steps before starting.
Tips & tricks beforehand
To operate a pressure washer safely (and quickly), check out the tips and tricks below:
Familiarize yourself with the machine
This is the first thing everyone must do.
Reading or skimming through the manual and familiarizing yourself with parts of the machine is vital for the whole procedure (e.g., utilization, storing, maintenance).
In general, it’s always a good idea to understand how your pressure washer works.
Place the pressure washer on a stable surface
Ensure the pressure washer sits on a stable, flat surface to avoid tipping over or moving.
Remove all loose items or debris around you
For a smoother experience, remove all the unnecessary items or debris in the surrounding area.
How to start an electric pressure washer
Electric pressure washers are user-friendly but always proceed with caution.
Check out these easy steps you can follow:
1. Attach the necessary hoses
Link the water inlet hose to the water supply and the other end to the machine.
Then, attach the high-pressure hose to the water outlet of the pressure washer and the other end to the gun assembly.
Ensure that the collar snaps once you connect the hose at the bottom of the gun assembly.
2. Choose the appropriate nozzle for your needs
Pull back the collar at the end of the gun and carefully attach the nozzle, then release the collar.
Each pressure washer nozzle has its purpose; you can identify it with its respective colors.
There are four basic types of pressure washer nozzles available: 0°, 15°, 25°, 40° plus a black nozzle for soap.
- Red 0° Nozzle – advisable for elevated surfaces since it provides the highest pressure, also commonly used to eradicate solid stains from concrete and metal.
- Yellow 15° Nozzle – works wonders on mildew and mold from PVC fences.
- Green 25° Nozzle – also called an all-around nozzle; perfect for decks, cleaning driveways, patios, or sidewalks.
- White 40° Nozzle – fit for cars, windows, or fragile areas. It provides a wide spray pattern that will be less likely to do damage.
- Black Nozzle – this tip is utilized when using soap or detergent at low pressure.
3. Flush out the air from the pressure washer system
Before turning on the motor, remember to clear any air from the machine.
From here, turn on the water first, point the gun downwards, and pull the trigger until only the water is flowing.
4. Plug the machine into a grounded outlet
The outlet should be in a safe area, far from or covered from the cleaning activity.
5. Turn the machine on and clean away
How to start a gas pressure washer
Gas pressure washers are typically a bit more involved than electric pressure washers.
Here’s what you need to know about starting one.
1. Monitor fuel and oil levels
When checking the oil level, the fuel valve should be “Closed” or “Off.”
Next, pull the dipstick, give it a good wipe, then dip it back. The oil level should be on the indication line. This doesn’t need to be done every time, but is a good habit to form.
2. Turn “on” everything
Follow the correct order of turning the switches:
- First, turn the fuel valve “On” or “Open” position.
- Next, turn the choke to the “On” or “Open” position.
- Finally, turn the throttle to the “Full Speed” Or “Max” position.
3. Flush out the air from the pressure washer system
4. Pull the chord to start the engine
The recoil usually doesn’t start in one pull, so you can do it a few times before it starts.
5. Turn the choke to the “Off” or “Close” position.
6. Get to work 💪
