How do I operate the Greenworks 2100 PSI pressure washer?

Press the push-button start on the unit, then squeeze the trigger on the spray gun to begin spraying and release it to stop spraying. The unit features a Total Stop System (TSS) that automatically pauses operation when you release the trigger, saving energy and prolonging pump life. To completely shut down, release the spray gun trigger, press the power button on the unit, and turn off the water supply.
