What is the proper startup procedure for the pressure washer?

First, connect the garden hose and turn it on, then squeeze the trigger and run water with the motor OFF until a steady stream appears to drain air from the system. Ensure the On/Off switch is in the OFF position, then connect the power cord to the outlet. Press the reset button on the GFCI plug to confirm the unit is ready. Finally, rotate the switch to ON (I) position to start the motor. To stop, release the trigger and rotate the switch to OFF (O) position. (Page 18)
