Question about Karcher Garden
It is recommended that once pressure washer is in operation and water flow thru wand is there ,that you do not allow off period between burst of no more that 2 minutes or you highly risk damage to your pump,not engine, due to overheating. See if Dump valve is adjustable,cheaper models not adjustable. This valve senses pressure/heat build up in pump when trigger is released, and is a secondery backup to release such heat/pressure to avoid pump failure. If you have repeatly left trigger off for more than 2 minutes in for prolonged periods of time,this is not good.
