How to Start a Power Washer: A Step-by-Step Beginner’s Guide
Learning how to start a power washer correctly is the first step to effective and safe cleaning. This guide will walk you through the process, ensuring you avoid common mistakes and get your machine running smoothly on the first try.
Pre-Start Safety and Preparation Checklist
Before you even think about pulling the starter cord, proper preparation is crucial. Always wear safety glasses and closed-toe shoes. Check your work area for obstacles and ensure good ventilation if using a gas model. Inspect the power washer for any visible damage, leaks, or loose connections.
Connecting Hoses and Selecting Nozzles
Connect your garden hose to the water inlet on the machine and turn on the water supply fully to remove air from the system. Next, attach the high-pressure hose to the pump outlet. For beginners, start with a wide-angle (40-degree white) nozzle. It provides a gentle spray perfect for learning and prevents surface damage.
The Step-by-Step Starting Procedure
Now, let’s get your machine running. For electric models, simply plug them into a GFCI outlet, turn on the water, and squeeze the trigger gun to release air before switching the unit on. For gas engines, follow these key steps:
1. Check the engine oil and fuel levels.
2. Turn the fuel valve to the “ON” position.
3. Set the engine choke to “CLOSED” for a cold start.
4. Turn the ignition switch to “ON.”
5. Pull the starter cord firmly and steadily.
6. Once the engine starts, move the choke to “OPEN.”
Always allow the engine to warm up for a minute or two before engaging the pump by squeezing the spray gun trigger.
Priming the Pump and Avoiding Damage
A critical step many beginners miss is ensuring the pump is primed. This means water is flowing through it before starting. With the water supply on and the spray gun trigger squeezed, you should see a steady stream of water. This prevents the pump from running dry, which can cause severe and costly damage in seconds.
FAQ: Common Power Washer Starting Problems
Q: Why won’t my gas power washer start?
A: Check the “obvious three”: Is there fresh fuel? Is the fuel valve on? Is the engine switch on? Also, a clogged air filter or old spark plug can prevent starting.
Q: My machine starts but has no pressure. What’s wrong?
A: This is often due to an unprimed pump or a kinked inlet hose. Ensure water is flowing freely before starting. Also, check for a worn spray tip.
Q: Is it safe to start a power washer indoors?
A> Never start a gas-powered pressure washer indoors due to deadly carbon monoxide fumes. Electric models can be used in well-ventilated garages but always check the manufacturer’s guidelines.
