How do I set up my Greenworks 2100 PSI pressure washer for the first time?

Start by attaching the telescoping handle to the main unit, then connect the high-pressure hose to both the pressure washer outlet and spray gun, ensuring connections are hand-tight and leak-free. Next, attach your garden hose to the water inlet and turn on the water supply completely, then plug the 35' power cord with in-line GFCI into a weatherproof outdoor outlet. The unit will be ready to operate once all connections are secure.
