Understanding Your Greenworks Pressure Washer
Components of a Greenworks Pressure Washer
Before using your Greenworks pressure washer, it’s important to understand its components:
- Motor: Powers the pressure washer.
- Water Inlet: Connects the garden hose to the pressure washer.
- High-Pressure Hose: Transfers pressurized water from the machine to the spray gun.
- Spray Gun: Controls the flow of water and attaches to various nozzles.
- Nozzles: Different tips that alter the spray pattern and pressure.
- Detergent Tank: Holds cleaning solutions for more effective cleaning.
- Power Cord (for electric models): Connects to an electrical outlet.
Safety Precautions
Using a pressure washer involves high-pressure water, which can be dangerous if not handled properly. Here are some safety precautions to follow:
- Wear Protective Gear: Always wear safety glasses, gloves, and non-slip shoes.
- Read the Manual: Familiarize yourself with the manufacturer’s instructions.
- Avoid Electrical Hazards: Keep the power cord away from water and avoid using the pressure washer in wet conditions.
- Never Point at People or Pets: High-pressure water can cause serious injury.
- Start with Lower Pressure: Test the washer on a small area to ensure the pressure is appropriate.
Setting Up Your Greenworks Pressure Washer
Assembling the Pressure Washer
- Unbox the Pressure Washer: Carefully remove all components from the box.
- Attach the Handle: Secure the handle to the main body of the pressure washer.
- Connect the High-Pressure Hose: Attach one end of the high-pressure hose to the water outlet on the pressure washer.
- Attach the Spray Gun: Connect the other end of the high-pressure hose to the spray gun.
- Insert the Nozzle: Choose the appropriate nozzle and insert it into the spray gun.
Connecting the Water Supply
- Attach the Garden Hose: Connect your garden hose to the water inlet on the pressure washer.
- Check the Water Supply: Ensure the water supply is clean and free of debris. A clogged water supply can damage the pump.
- Turn on the Water: Fully open the faucet to ensure a steady flow of water to the pressure washer.
Electrical Connection (for Electric Models)
- Plug into a GFCI Outlet: Ensure your pressure washer is plugged into a Ground Fault Circuit Interrupter (GFCI) outlet to prevent electrical shocks.
- Avoid Extension Cords: If possible, plug the pressure washer directly into an outlet to avoid voltage drops.

Operating Your Greenworks Pressure Washer
1. Priming the Pump
- Release Air from the System: Squeeze the trigger on the spray gun to release air from the system. This ensures water flows smoothly through the pump.
- Check for Leaks: Inspect all connections for leaks and tighten if necessary.
2. Starting the Pressure Washer
- Turn on the Power (Electric Models): Flip the power switch to the “On” position.
- Pull the Starter Cord (Gas Models): If you have a gas model, pull the starter cord to start the engine.
3. Using the Spray Gun
- Select the Nozzle: Choose the nozzle appropriate for the task. Lower-degree nozzles (0°, 15°) are more powerful and suited for tough stains, while higher-degree nozzles (25°, 40°) are gentler and better for general cleaning.
- Adjust the Spray Pattern: Aim the spray gun at a small test area and adjust the spray pattern by changing the nozzle if necessary.
- Maintain a Safe Distance: Hold the spray gun at least 12 inches away from the surface to avoid damage.
4. Applying Detergent
- Fill the Detergent Tank: Add the recommended detergent to the detergent tank.
- Use the Soap Nozzle: Attach the soap nozzle (usually black) to the spray gun. This nozzle is designed for applying detergent.
- Apply the Detergent: Spray the detergent on the surface and let it sit for a few minutes to break down dirt and grime.
- Rinse with Water: Switch to a higher-degree nozzle and rinse the detergent off the surface.
Tips for Effective Cleaning
Cleaning Different Surfaces
- Driveways and Sidewalks: Use a 25° nozzle for general cleaning. For tough stains, switch to a 15° nozzle. Move in a sweeping motion to avoid streaks.
- Decks and Patios: Use a 40° nozzle to prevent damage to wood or composite materials. Clean in the direction of the grain.
- Vehicles: Use a 40° nozzle and maintain a safe distance to avoid damaging the paint. Use a detergent designed for vehicles.
- Siding: Use a 25° or 40° nozzle. Start from the bottom and work your way up to avoid streaking. Be cautious around windows and vents.
Removing Stubborn Stains
- Use a Turbo Nozzle: For particularly stubborn stains, use a turbo nozzle if your pressure washer includes one. It combines the power of a 0° nozzle with a rotating spray pattern.
- Apply Detergent First: Let the detergent sit on the stain for a few minutes before rinsing.
- Increase the Pressure Gradually: Start with a lower pressure setting and increase as needed.
Maintaining Your Greenworks Pressure Washer
After Each Use
- Flush the System: Run clean water through the pressure washer to flush out any remaining detergent.
- Disconnect the Hoses: Remove the high-pressure hose and garden hose from the machine.
- Drain the Water: Allow any remaining water to drain from the pump and hoses.
- Store Properly: Store the pressure washer in a dry, cool place. Coil the hoses neatly and store the spray gun and nozzles in their designated spots.
Routine Maintenance
- Check for Wear and Tear: Regularly inspect the hoses, spray gun, and nozzles for signs of wear and replace if necessary.
- Clean the Nozzles: Remove debris from the nozzles using a needle or the nozzle cleaning tool included with your pressure washer.
- Change the Oil (Gas Models): Refer to the manual for the recommended oil change schedule. Use the appropriate type of oil for your model.
- Inspect the Air Filter (Gas Models): Clean or replace the air filter regularly to ensure optimal performance.
Winterizing Your Pressure Washer
- Drain All Water: Completely drain water from the pump, hoses, and detergent tank to prevent freezing and damage.
- Add Pump Saver: Use a pump saver product to protect the pump from freezing and corrosion. Follow the manufacturer’s instructions.
- Store Indoors: Keep the pressure washer in a heated area during the winter months.
