In the beginning, ns hated beginning my power washer. We’d wrestle frequently until i learned to work with the machine. Currently we’re the ideal of pals, and also you are about to learn exactly how you have the right to be too. 

The number one reason of a hard-to-pull power washer cord is the incorrect starting procedure. Follow these 5 steps to conveniently start a strength washer:

Set gas, choke and switch come “On”Connect garden hoseTurn garden water tap onPull and hold lance triggerPull start engine

In this post, you’ll find out why your pressure washer is stiff to pull and also what to have the right to do to stop the startup wrestle.

What reasons Stiff Starter Cord?

In mine workshop, I view a ton of press washers in for repair. Many suffer from broken pull cords and customers usually define a similar kind fault – stubborn or hard to crank end the motor, faulty traction cords, etc.

Of course, we recognize that’s not the problem. In the majority of cases, it’s an incorrect beginning procedure i m sorry is the root reason of both the stiff traction cord and the disproportionate number of snapped pull cords.

So what’s walking on, why is the so stiff? The price is simple and the equipment will seem apparent when you know what’s actually going on. Once you traction on a strength washer pull cord, girlfriend aren’t just transforming over the engine, you’re also turning over the press pump.

The stiffness you experience in the cord is a good thing, it means the pump is doing its job, it’s building pressure. Building pressure is tough work, the much more you pull over the motor, the harder it is to pull the cord. One engine won’t start unless the engine transforms over fast sufficient to fire the spark plug, that’s around 300 rpm. Obviously, that’s not going come be possible with all that pressure gathered inside the pump.

The systems is to release the pressure, to perform so, just pull and hold the lance trigger. And also that’s what we’ll covering next.

The Correct power Washer beginning Procedure

Before beginning any engine it’s a good practice to inspect the oil level and readjust if necessary. I recommend my client to inspect the oil through every gas fill.

Pressure washers regularly lay increase for long periods between uses, I also advise client to use a gas stabilizer in the fuel. The helps keep the gas fresh and prevents carburetor issues. Girlfriend can check out the gas stabilizer price and also a video clip on correct use below on the “Power washer maintenance tools page”.

Here’s the correct beginning procedure in a little much more detail:

The fix – change the carburetor to rise vale however you’ll need to change that oil too. Best to turn the gas madness off when the to wash is not in use, this relieves press on the to rise needle.

The float valve can quickly be replaced inspect out “Carburetor troubleshooting” article or check out the video here.


Compression release Valve

An engine demands compression to fire and also produce power, compression in itself results in a stiff traction cord and so to relax the an obstacle manufacturers rental a basic component known as a compression release valve.

As its surname suggests, the release valve publication compression native the cylinder. That does so by opening the exhaust valve, simply a touch while traction starting.

When the engine starts, the relax valve is redundant. Relax valves do offer trouble and may an outcome in a stiff traction cord, customers commonly describe the cord as snapping from your hand.


The resolve – replace the relax valve. Part engines space a gift to work on, instead of the valve is a thirty-minute project (Honda) various other engines will require a complete strip under to access the valve.


Valve Train Issue

A valve that doesn’t open up in time or just doesn’t open will cause excessive engine compression. And also as you’ve already heard, engine compression may an outcome in a stiff pull cord.

A valve that doesn’t open in time is likely a matter of adjusting the valves, it’s a pretty typical maintenance task. You can inspect it the end here, this write-up covers a mower engine however the process is identical “Adjusting valve lash” or examine out the video clip here.


A valve that doesn’t open is a much more serious issue. It may mean a rocker has damaged or a push rod has bent depending upon the engine type.

It may additionally mean a camshaft is faulty and also while this isn’t a hugely usual issue however does happen.


Broken Shear-key

A shear key is a small metal crucial and has two functions. The aligns the flywheel and crankshaft and its second and equally important role is come shear when called upon.

When an engine concerns a suddenly stop, (for eg, pump seizure) and because the flywheel tote mass, it’s skinny to store turning. In fact, the flywheel tote sufficient energy to twist and also destroy the crankshaft. It’s just prior to this moment, the shear-key breaks and also decouples the crankshaft from the flywheel.

When the shear-key decouples, the time of the engine is off and also will reason a stiff traction cord. As said, a power washer’s broken shear an essential is not hugely common, yet still a possibility.


Check the end this post, it details exactly how to check and how to replace a shear key “Engine kicks back when starting” or examine out the video clip here.


Engine Damage

Small engine failure is not that usual in a well-maintained motor. Indeed also a poorly maintained motor is surprisingly durable.

Let them run out of oil though and also it’s over, lack of oil will permit internal components to acquire so hot, they fuse together. However, before that happens, the engine begins to obtain tight and also that will an outcome in a stubborn cord.


Oil conditions will tell you a lot about what’s going on. Very low, or no oil, are afraid the worst.


Pump Damage

Pumps work-related hard and also do fail. As soon as they fail they often seize, which will certainly make the traction cord hard or really stiff to pull. Countless pumps room oil because that life and don’t need maintenance for this reason don’t feeling bad around it.

However, generally, if a pump has an oil fill and also drain hole, it method oil should be changed. ~ above pumps that do permit an oil change, change about every 100 hours of operation.
