How do I set up and assemble the Greenworks pressure washer before first use?

Assembly includes installing the wheels by inserting the axle through the wheel and frame, securing with a pin; assembling the gun holder by lining up screw sleeves and tightening with a Phillips head screwdriver; installing the handle by pushing and holding the push-pin button while sliding onto the frame; connecting the high-pressure hose to the water outlet connector and trigger gun; connecting the garden hose to the water intake; and finally connecting your desired spray tip. Before operation, run water for 120 seconds with the motor OFF to drain air from the system. (Pages 11-15)
