3. Connect Power: Plug the 16ft power cord into a grounded electrical outlet. Ensure the outlet meets the power requirements of the pressure washer.
4. Power On: Turn the power switch on the unit to the "ON" position. The motor will start briefly and then shut off, indicating the Total Stop System (TSS) is active and the unit is pressurized.
