Just trialing this power washer Wolf petrol 200 bar.
Although it starts ok I am not sure about something.

When shutting it down the procedure is:
Turn idle to low
turn fuel off
Turn switch off.

However when starting there is no mention of the idle switch in the
instructions where that should be positioned for start up, and there is
no mention on how this is used in the instructions, although by trial
and error it appears to give more `bar`(power) when on high idle.

Any one got any ideas on this. Should it be on low for starting?
