Selecting The Scrub Pressure Current Limits - Nilfisk-Advance Adphibian AX 651 Multi EDS Service Manual

Selecting the Scrub Pressure Current Limits

The Adphibian, AX 651 Multi EDS and AquaPLUS use the combined scrub brush motor current draw to determine if the
scrub pressure is correct for the selected scrub mode.
• If the current draw goes above the upper limit, the scrub deck lift actuator raises the deck until the scrub motor
current draw is within the selected range.
• If the current draw goes below the lower limit, the scrub deck lift actuator lowers the deck until the scrub motor
current draw is again within the selected range.
You can select the scrub motor upper and lower current limits to compensate for different brush and/or carpet types.
The current limit settings range from 0 to 9, with 0 being the least load/current draw and 9 being the greatest. To select
the current limit range for a particular scrub mode:
1. Turn the Key Switch (A) to the off position.
2. Press and hold the button combo for the scrub mode you wish to change as listed in the table below.

3. While holding the appropriate button combination, turn the Key Switch to the on position.
4. Continue to hold button combination until the programming indicators light.
5. Release the buttons. The display will now show a scrub brush icon and a number from 0 to 9.
6. Press and release the Scrub ON Switch (J) to toggle through the numbers. (Refer to the table below for the lower
and upper current limits for each setting).
7. Once the desired setting is selected, press the Scrub OFF Switch (H) to save this setting. The display will now
show a key icon to indicate the procedure is done.
8. Turn the Key Switch to the off position. The new setting will be saved and will remain in effect until it is changed
again.
