Metal in oil
- Examine oil in pump to see if there is metal in oil.
- If you find traces or pieces of metal, your pump
has damaged components.
Dirt in water
- Verify if there is dirt in nozzle tip or in valves in pump.
- If nozzle is plugged, clean or replace it.
- If valves in pump are clogged, clean valves.
- If valves in pump are damaged, replace valves.

- Make sure you have the right nozzle size. The black
nozzle will drop pressure in order to use chemical injector
and is only for soap or chemical. If you are not using soap,
use a different color.

Wrong nozzle size
- Make sure you have the right nozzle size.
Unloader adjusted improperly
or damaged
- Check pressure of pump with a pressure gauge and adjust
