The sensitivity of these three features can be changed to meet the needs of the floor that is being
burnished. They can be made more sensitive, making the machine raise and lower the head more
often to ensure that proper pad pressure is being maintained even over small changes in floor
conditions. These features can also be made less sensitive, making the machine react less to
changes in floor conditions. Making the machine less sensitive can be helpful if the location that is
being burnished has particularly wavy floors and the machine can not keep up with the changing floor
conditions. Care should be taken when changing the sensitivity. When the machine is too sensitive
or not sensitive enough, there is a possibility that the floor finish can be damaged.
To change the sensitivity of the machine, the programming mode must be entered. To do this, press
and hold the "OFF" button. Then press and hold the "UP" and "DOWN" buttons simultaneously. Then
release the "OFF" button. Then release the "UP" and "DOWN" buttons. The machine is now in the
programming mode. Notice that the "ON" light is now dimly blinking.
To change the "First Time to Calibrate" setting, after entering the programming mode, press and
hold the "ON" button. Then press and hold the "DOWN" button. Release the "ON" button, then release
the "DOWN" button. A combination of lights will illuminate in the pad pressure array. By pressing the
"UP" or "DOWN" buttons, the lights will move accordingly. The closer the array is to the word "MIN",
the quicker the machine will calibrate itself. The closer the array is to the word "MAX", the longer it will
take for the machine to calibrate itself. During this time, the machine is finding an average floor
height, therefore if the machine calibrates itself too quickly, it might not have a true representation of
the floor. If the machine calibrates itself to slowly, it may never lock-in to an average. Once the correct
sensitivity adjustment has been made, press the "OFF" button to exit the programming mode and
save the setting.
To change the "Time to Recalibrate" setting, after entering the programming mode, press and hold
the "ON" button. Then simultaneously press and hold the "Heavy Pad Pressure" and "Light Pad
Pressure" buttons. Release the "ON" button and then simultaneously release the other two buttons.
A combination of lights will illuminate in the pad pressure array. By pressing the "UP" or "DOWN"
buttons, the lights will move accordingly. The closer the lights are to the word "MIN" the quicker the
machine will start to recalibrate itself after it encounters a high or low spot in the floor. The closer the
lights are to the word "MAX", the longer it will take for the machine to start to recalibrate itself after it
encounters a high or low spot in the floor. Once the correct adjustment has been made, press the
"OFF" button to exit the programming mode and save the setting.
