You will need to adjust the lance on the end by twisting the end of the nozzle. This way the machine draws chemical at low pressure.

The pump is blocked or the motor shaft going into the pump is seized. You will need to remove enough of the cover to expose the shaft and pump..... You can try WD-40 or a penetrating oil from a spray can... and then try to rotate the shaft by had or "carefully" with a tool - vice grips or plyers......

It sounds like there may be a pressure leak somewhere in the system. The machine cuts off when there is no flow of water past it. If it is leaking then there is intermittent flow. Which would make the machine run then stop continuously.

If you are talking about the oil in the pump then it should be 10W30 but must be NON DETERGENT. Remember the reservoir should only be 1/3 full

Take the wand hose off the washer itself and you will likely find a filter outfit that gets plugged up. Take it out and clean it real good. Mine was full of stuff out of the hose that gets in when the hose lays on the ground and stuff gets in. Also if hose has been used to drain anything. My filter was plugged and with the pressure it created the washer would not shut off. There could be a filter in the wand area in some models.

If you are unable to shut off the pressure from the wand, there may be an issue with the unloader valve that is stopping it from switching into bypass mode when the trigger wand is released. The unloader valve is designed to respond to the spike in pressure created when the trigger wand is released, and to divert the flow of water coming from the pump to bypass the pressure hose and flow back into the intake end of the pump. If the unloader valve fails to switch into bypass mode, water may continue to flow out of the trigger wand. This may also cause damage to the wand. If you are unable to shut off the pressure from your power washer, stop the engine and discontinue use immediately. The unloader valve should be removed and possibly replaced if found to be malfunctioning. The inability to stop the flow of high-pressure water from the wand can be dangerous and should be fixed before continuing to use the machine.
