Here’s a step-by-step guide to help you start your pressure washer the right way.
Tools and Supplies You’ll Need:
- Water source (garden hose)
- Pressure washer hose and wand
- Fuel and oil (for gas models)
- Extension cord (for electric models, if needed)
- Safety gear: gloves, goggles, and closed-toe shoes
Step-by-Step Instructions for Starting a Pressure Washer
1. Prepare the Area
- Clear the Work Area: Make sure the area you’ll be cleaning is clear of obstacles, pets, and people. Pressure washers are powerful, and you don’t want to accidentally spray anyone or anything delicate.
- Position the Pressure Washer on a Flat Surface: Ensure the machine is stable and won’t tip over during use.
Steps for Gas-Powered Pressure Washers
Gas pressure washers are more powerful than electric models, but they require extra steps for starting.
2. Check the Oil and Fuel Levels
- Oil: Locate the oil dipstick and check that the oil level is adequate. If it’s low, top it off with the manufacturer-recommended oil.
- Fuel: Fill the gas tank with fresh, unleaded gasoline if it’s empty. Never use old fuel, as it can gum up the engine.
3. Connect the Water Supply
- Attach the Garden Hose: Screw one end of your garden hose to the water inlet on the pressure washer and the other end to a water spigot. Turn the water on fully.
- Check for Leaks: Ensure there are no leaks in the connection between the hose and the pressure washer.
Important: Never run a pressure washer without a water supply, as this can damage the pump.
4. Attach the Pressure Washer Hose and Wand
- Connect the Pressure Hose to the Pump: Attach the high-pressure hose to the outlet of the pressure washer.
- Attach the Wand: Connect the spray wand to the other end of the pressure hose.
- Select the Nozzle: Choose the right nozzle for the job. Start with a 25-degree or 40-degree nozzle for general cleaning.
5. Prime the Pump
Before starting, you need to get water flowing through the system:
- Squeeze the Trigger: With the machine turned off, squeeze the trigger on the spray gun to release air and prime the pump. This will allow water to flow through the hose.
- Hold the trigger until water comes out of the nozzle in a steady stream.
6. Start the Pressure Washer
- Turn the Fuel Valve On: Locate the fuel valve lever (usually near the gas tank) and turn it to the “ON” position.
- Set the Choke: If the engine is cold, turn the choke lever to the “ON” or “CLOSED” position.
- Turn the Engine Switch On: Make sure the engine switch is in the “ON” position.
- Pull the Starter Cord: Hold the pressure washer firmly with one hand and pull the starter cord with the other in a smooth, fast motion. You may need to pull it a few times to get the engine to start.
- Adjust the Choke: Once the engine is running for a few seconds, move the choke lever to the “OFF” or “OPEN” position.
Your gas pressure washer should now be up and running!
Steps for Electric-Powered Pressure Washers
Electric pressure washers are quieter and easier to start but still require careful setup.
2. Connect the Water Supply
- Attach the Garden Hose: Screw the garden hose onto the water inlet, just as you would with a gas-powered model. Turn the water on fully.
- Check for Leaks: Make sure all connections are tight and that no water is leaking.
3. Attach the Pressure Hose and Wand
- Connect the High-Pressure Hose: Attach the pressure hose to the outlet of the pressure washer.
- Connect the Spray Gun: Attach the wand to the other end of the high-pressure hose.
- Select the Appropriate Nozzle: Choose the nozzle that suits your cleaning needs.
4. Plug the Pressure Washer In
- Use a Proper Extension Cord: If needed, use a heavy-duty extension cord rated for outdoor use that matches the power requirements of your pressure washer.
- Connect the Power Cord: Plug the power cord into a grounded electrical outlet.
5. Prime the Pump
- Squeeze the Trigger: With the machine off, pull the trigger on the spray wand to release any air in the system and allow water to flow through.
6. Start the Pressure Washer
- Turn the Power On: Find the power switch (usually labeled “ON/OFF” or with a power symbol) and turn the machine on.
- Start Spraying: Once the machine powers up, squeeze the trigger to begin using the pressure washer.
Final Checks Before Using the Pressure Washer
- Test the Spray Pattern: Start by spraying a small, inconspicuous area to ensure the pressure is right and the nozzle is suitable for the job.
- Adjust the Nozzle as Needed: Depending on the cleaning task, you may want to switch to a narrower or wider nozzle.
Safety Tips for Operating a Pressure Washer
- Wear protective gear: Always wear goggles, gloves, and closed-toe shoes when using a pressure washer to protect yourself from debris.
- Avoid spraying people or pets: The high-pressure spray can cause serious injuries.
- Be cautious around electrical outlets and fixtures: Don’t spray directly at electrical outlets or wiring to avoid shocks or shorts.
Final Thoughts
Starting a pressure washer isn’t difficult, but following the proper steps ensures your machine runs smoothly and efficiently. For gas pressure washers, make sure the fuel, oil, and choke are properly set. For electric models, ensure all electrical connections are secure. Once it’s running, you’re ready to tackle tough cleaning jobs like driveways, siding, and decks with ease.
