[. . . ] If the machine is not working as it should, has been dropped, damaged, left outdoors or flooded with water, return it to a service center. Do not pull the machine by the cord, do not use the cord as a handle, close a door on the cord, or pull the cord around sharp edges or corners. Keep the cord away from heated surfaces. Do not handle the plug, the cord, or the machine with wet hands. [. . . ] Pre-spray the area to be cleaned with a pump-up sprayer. Turn on the high pressure pump by placing the HIGH PRESSURE/HEAT selection switch (2) in the UP position, to select the High Pressure Pump. NOTE: The high pressure pump and the heat can not operate at the same time. NOTE: this switch is off when it is set to the middle position and neither the high pressure pump nor the heater is selected. The 85 bar pump is not self-priming; you will need to prime the high pressure pump using the `power prime' system: turn on both the pump and the vacuum, cover the hole in the hose barb with your hand, then depress the Power Prime Pedal. This will pull trapped air out of the pump and into the recovery tank , priming the pump. You will notice a `tone' change in the pump (smoother, with less of a rattle), and the water being pulled into the recovery tank will change from a white, full of air stream of Priming may take 20 - 60 seconds, or even longer sometimes, and it will require a full solution tank. When the pump is primed, let off the Power Prime Pedal, and turn off the pump and the vacuum. Then press the Power Prime Pedal once again, for a moment, to release the line pressure; you will hear a `swoosh' of air as the back pressure in the lines is released. The pump will need to be primed anytime air gets into it -- try not to let the pump run dry. If you choose to use the automatic pump-out feature, MAKE SURE THE CAP IS REMOVED FROM THE HOSE CONNECTION ON THE BACK OF THE MACHINE BEFORE YOU TURN THE SWITCH ON. This pump will run continuously once you turn it on, and if it tries to pump out water, but the cap is still on the hose fitting, the pump may be damaged. Turn on the vacuum (3) and turn on the dump pump (if you chose to use this feature) (5). If you are not using the auto-fill or auto-dump features, turn off the pump and vacuum when the solution tank gets low; fill the solution tank, and empty and clean the recovery tank. If you use the auto-fill and/or auto-dump features, you will not need to stop working to fill and/or empty your tanks. When the job is finished, turn off the automatic pump-out pump turn and turn off the water source, if they were employed. Use the vacuum hose to suck the remaining solution from the holding tank into the recovery tank. Run a few gallons of clean water through the system. Completely empty the recovery tank by placing the drain hose over a floor drain, toilet, or tub, and removing the cap. You can clean the tank at this time with clean water. When the tank is empty, cap the drain hose and place it back in the hook and loop holder. Disconnect the hoses from the cleaning tool, and reel them up onto the hose spool. [. . . ] NOTE: before servicing any component in the base cabinet, remove the hoses and spool before opening the tanks. Attach a garden hose to the auto-fill hose connection above the holding tank fill hole, and connect the other end of the hose to your water source. Make sure the float that hangs into the solution tank from the auto-fill valve is free of obstruction and can move freely. This system does not require a high pressure water source. [. . . ]
