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

Thanks Mitchell.

I will test out the hose connector after work, though I bought it brand new from Bunnings, doesn't look like it should be a problem, but you never know.

I will also give this a try 'you pull back on the fittings release mechanism, push the connector onto the machine firmly then let go of the release mechanism'.  I have noticed that when I have tried to pull the trigger, the trigger doesn't seem like it wants to move, is there a locking mode on this spray gun?  I used to use Karcher K3 before, I don't have these sort of issues until after 5 years, my Karcher started leaking where the hose connects to the machine, so I have decided to buy a new one that is cheaper.

Hi @deniselai28 

You should be able to pull the trigger with no issues. My best advice is to make sure that water is flowing into the hose and into your machine before turning it on. 

If you need further assistance, please let us know.
