START UP
1. Perform daily and periodic maintenance as specified in this Owner’s Manual.
2. Connect all required hoses, including a garden hose for water supply.
3. Connect the cleaning tool to the length of hose required to perform
the cleaning.
Water box must be full prior to ignition.
The machine cannot be run in the “IDLE” position for cleaning upholstery, carpet or

light may come on momentarily. This indicates that the high temp solenoid is acti-
vated to control water temperature.
