How to Start a Power Washer: A Step-by-Step Guide for Beginners

Starting a power washer for the first time can seem daunting, but it’s a straightforward process once you know the steps. This guide will walk you through everything you need to know to get your machine running safely and efficiently.

Pre-Start Checklist and Safety First

Before you even think about pulling the starter cord, a few crucial preparations are necessary. Always prioritize safety by wearing protective goggles and closed-toe shoes. Check your work area for hazards and ensure pets and children are at a safe distance.

Essential Pre-Operation Steps

First, connect a garden hose to the washer’s water inlet. Turn on the water supply fully and squeeze the trigger gun to purge any air from the system until a steady stream flows out. This primes the pump. Next, check the engine oil level using the dipstick, topping up if necessary with the oil type recommended in your manual. For gas models, ensure you have fresh fuel in the tank.

The Step-by-Step Starting Procedure

Now, you’re ready to start. For electric models, simply plug in the unit, turn the switch on, and you’re ready to go. For gas-powered washers, follow these steps:

1. Move the fuel valve to the “On” position.

2. Set the choke lever to “Choke” if the engine is cold.

3. Turn the engine switch to “On.”

4. Firmly grasp the starter cord handle and pull briskly. It may take 2-3 pulls.

5. Once the engine starts, gradually move the choke lever to “Run.”

Common Beginner Questions Answered

Why Won’t My Power Washer Start?

The most common issues are an empty fuel tank, stale gasoline, a closed water supply, or an engaged safety trigger lock. Always check these first.

Should I Use Hot or Cold Water?

Most residential pressure washers are designed for cold water. Only use hot water if your specific model is rated for it, as heat can damage seals and pumps.
