The washer doesn’t come ready to use. Upon arrival, you have to assemble its parts to start using it. If some parts of the washer arrive assembled, you shouldn’t use it and contact customer support of the manufacturer.
Here are the assembly instructions for 2000 PSI / 1.2 GPM Electric Pressure Washer GPW.
Assembling Wheels and Handle
The first part you would assemble in this washer is its wheels. You assemble the wheels using the axle. First, you insert these axles into the wheel and through the frame. Then, you slide the washer past the pinhole. In the end, you have to insert the pins through the pinhole fastening the wheels.
Before assembling the handle, you should assemble the gun holder on it. Do this by matching the screw sleeves with the holes screwing them. You can assemble the handle by sliding the upper handle into its place while holding the push-pin button on it down.
Assembling Wand and Gun
Now you have to connect the spray wand with the trigger handle. Simply, push the wand’s end into the handle and rotate to tighten. Check for the tightness by pulling the wand.
To connect the hose with the trigger handle, push the hose into its position and tighten its lock clockwise. You may want to apply dish soap to the rubber seal of the hose to make this installation easy.
Similarly, connect the other end of the high-pressure hose to the water outlet connector.
Note the condition of the pressure hose. It shouldn’t be kinked.
Connect the garden hose to the water inlet by rotating its screw. Before you make this connection, clean the water supply off debris and dirt by letting it flow for half a minute. Also, the screen in the water inlet should be clean and free of damage.
Note that the water supply should be a hose connected to a faucet. You shouldn’t supply water for the pressure washer from a bucket.
Also, take note of the local regulations. Some localities prohibit connecting pressure washers with drinking water sources as doing so can lead to harmful chemicals getting mixed with the water.
Now you have connected all its parts, the next step is to connect it with the power outlet, turn on the water supply, and start using it to wash the surface.
Let’s learn the detailed process.
Starting the Washer
Before you start pumping water from the pump, you have to get rid of all the air and debris caught within its high-pressure hose. You can release this air by turning the water supply on and without tuning on the pump, you have to pull the trigger until the water flow is steady.
Connecting Power Supply
With the on/off switch turned off, connect the cord with the power outlet. Push the reset button on the plug and turn the on/off switch to the on position.
After removing the cap from the soap tank, it’s easy to and the detergent and detergent solution. Follow the instructions given on the bottle of detergent to make a solution if you got a concentrated product. And only use those products which are suitable for pressure washers.
You can apply the detergent using the low-pressure nozzle of the pressure washer aka the soap nozzle. Use the black spray tip at the widest angle to spray the detergent on the desired surface.
Once you have applied the soap to the surface, let it react with the stains. But make sure to not let it dry to prevent streaking.
After you have applied the detergent, it is imperative that you let the remaining solution flow out of the spray want. You can do this by squeezing the trigger after pointing the gun in a safe direction.
Get clean water running through the soap tank after you have used it. You can do this by filling the tank with clean water and spraying it in a safe direction. If the soap flows out from the tank on the first go, you can stop the process. Don’t shy away from filling the tank a second time with clean water to clean the tank if soap remains in it afterward.
Selecting and Changing the Nozzle
A black nozzle is used to apply detergent. But once you have done with the detergent, you have to select a nozzle with a narrower angle and higher pressure. Use turbo nozzle if you want to do intense cleaning. If otherwise, you can choose between white and green nozzles. the white nozzle is wider giving a 40-degree angle for spray and is used for light cleaning. For more intense washing and rinsing steps, people use the green nozzle that has a 25-degree angle.
To change the nozzle you have to first turn off the washer from the power outlet. Make sure that you have released pressure from the wand before pulling the quick-connect collar to release the spray tip. Now, place your hand over the spray and pull the collar. The nozzle should release in your hand.
Now get the nozzle you want to use in the next washing step. Keep the trigger handle locked with the help of the safety lock. Pull the quick-connect collar back and push the desired nozzle in its place before pushing the collar back into its place.
Once you have changed the spray tip – otherwise known as the nozzle – you can proceed to rinse the surface. If you are unsure about the spray tip to use, start experimenting with a low-pressure nozzle and more towards narrower tips.
Rinse the surface from top to bottom in overlapping strokes to thoroughly cover the whole area.
Moving the Washer
During the washing cycle, you may face the need to move the washer across the surface. If such a need arises, the first step is always turning the power supply off. Then, pull the handle towards yourself until the washer balances on its wheels. Now, you can roll it to the desired position.
After you have completed the task, you should release the water pressure from the spray wand and high-pressure hose. Also, get rid of all the detergent in the soap tank. This makes an essential part of readying the washer for storage. You shouldn’t leave fluid in it.
After letting all the fluid out of the hoses, switch off the water pump and plug out the power cable from the power outlet. When not in use, keep the safety lock engaged.
Storage and Maintenance
Take care of the cord and hoses when you prepare the unit for storage. These items should be wrapped carefully to avoid damage and bending.
- Never store the washer in the outdoor area even if the storage period is short. Keep it in a covered area and away from weathering effects. Also, take note of the temperature of the place in which you will store it. The pressure washer shouldn’t remain at a place with freezing temperatures. Only those places where the temperature is higher than 32° should be considered for storage.
- The area should also be free of frost. Keep it away from the furnace to prevent the pump seal from drying out.
- Only get help from technicians skilled for maintenance works. Never try to service the unit without unplugging it from the power outlet. If in doubt, contact the service center of Greenworks.
- If a cord or hose is damaged, source only an identical replacement part for it. The use of different spare parts can be dangerous.
- Never use commercial solvents, brake fluids, and penetrating oil to clean the washer’s plastic parts. These solvents can damage these parts making the washer dangerous to use.
- If you want to clean the nozzle, you do it by taking it off. Unclog the spray tip with the provided tip cleaning tool. Now, run clean water over it backward. Pour water on its outside so it can go inside.
A pressure washer can make cleaning a lot easier for you. It can speed up the washing process for most outdoor surfaces. Plus, we get help from it in getting rid of the toughest stains. Still, the machine comes with some risks. And if you are not careful enough, it can cause serious harm to your health or property.
To reduce these risks, it’s important for the users to practice due diligence while operating it. One step to mitigate this risk is to understand the washer and know how to shut it off when necessary. Using safety gear and right footing also increases the likelihood of its safe use.
