How to correctly use the pressure washer?

[ivanptr]

 Ozito 1800W 2030PSI High Pressure Washer - Bunnings Australia

This is a stupid question but we just need to ask..
we have read the manual but still have no clue:

So we tried to run water through the washer,

but when we switch on the garden tap,

should we at the same time  turn on 1) the power of washer  + 2) squeeze spray wand trigger to bleed water pressure ?

If we dont squeeze the trigger, when too much water goes into the washer, wont the pressure burst the water pipes of our house ? 

We were not sure what we did, we just heard a loud humming noise when we run the water through the machine..

And we used the garden hose which is not the right size too (that we need to remove the filter)

Thank you for any advice

We are trying to pressure wash the foundation before waterproofing it like what @MitchellMc suggested

We finally have time to finish off this project we have bought all the materials we excavated too

Hi @ivanptr.

You'll need to pick yourself up a standard garden hose. It will include all the connections for the tap and machine. 

Screw the included universal tap connector onto your tap, allowing you to click your hose on. The universal connector fits two different-sized taps, so if it doesn't immediately screw onto your tap, remove the smaller insert to reveal the larger size screw.

Once your hose is connected to the tap, turn it on and run water through the hose, then turn it off. Next, click the other end of the hose onto the machine's inlet port. This would be where the filter you had previously removed was. Turn the water on at the tap and wait a few seconds. In the meantime, ensure the high-pressure hose is connected securely to the front of the machine and has the spray gun and lance attached.

Turn your powerpoint on that the extension cord is plugged into. With the machine itself still switched off, hold the spray gun's trigger until you see water coming out of the tip. The machine is now primed; you can release the trigger and turn the unit's power switch on. This will engage the motor, and you will be able to begin spraying.

At no time will high pressure from the machine damage the pipes in your house. The high pressure is only made after the water goes past the motor. The loud hum you heard was likey air purging from the system, or you switched the machine on at its power switch, and the noise you heard was the motor running.

Please let me know how you go and if you have further questions.

@MitchellMc  we tried and could click the filter onto one end of hose,

but the manual says the hose cannot be longer than 8m and we checked, all hoses in bunnings are at least 15meters long, would that still work?

[MitchellMc]

Hi @ivanptr,

If you purchase the hose in your picture, you can cut it down to eight metres in length and re-attach the fitting provided with the hose. They unscrew off the hose. Just unscrew the lower grey section whilst holding the orange section.

I can't imagine why a 15m hose would not work, but I'd suggest sticking to what the machine manufacturer recommends.

Hi can you please help I followed the instructions exactly but it sounds like the motor is starting up and then there is squeal sound that ebbs away and then nothing. I turn it off then worried I will break it. Why? What is happening? I tried it twice with the exact instructions but it still doing  the same thing. I've only used this machine the one time, this would be my second.

Hi @jacquiw,

Thank you for your question and welcome to the Bunnings Workshop community, it is great to have you with us.

The cause of the squealing could be a number of things such as pump cavitation which is a phenomenon that occurs when the water supply to a pump is insufficient. The squealing could potentially be solved by increasing the flow of water to the pressure washer. Check for kinks in the hose, if there are none, increase the flow of water through the tap.

Another potential cause of the squealing is air trapped in the system. Fixing this would involve bleeding the system by running the pressure washer without the spray tip until a steady stream of water flows through the nozzle.

You should start by trying these two things. If you find the issue persists, there may be an issue with the machine that would likely be covered by the warranty.

Let me know how you go, I'm happy to help troubleshoot further if you require it.

Thank you, I will give that a shot next time. I noticed when I used it that it did the sqeal and then I pushed the trigger and the water came out. It kept squealing when ever I let it go again but kept working. I will implement your tips. It says a 8m hose but how on earth would you do your backyard with that!!

If you have any further trouble, I'm more than happy to assist.
