A Low Battery Indicator – This indicator will fl ash when the battery requires charging.
B Horn Switch – This switch will sound the horn as long as the switch is held.
* Horn Indicator: Lights up when the horn switch is pressed.
C Parking Brake Indicator – This indicator is currently not used.
D Headlight Switch – Turns the headlights and taillights ON or OFF.
* Headlight ON Indicator: Lights up when the lights are ON. It is OFF when the lights are OFF.
E Speed Controller Fault Code Status Light – This light will fl ash on and off identifying a speed controller fault. Note: Refer to troubleshooting chart in this manual for
explanation.
F Hydraulic Filter Plugged Indicator – Indicates when the hydraulic oil fi lter should be serviced. Have your Nilfi sk Service Center check the machine. SERVICE NOTE:
This light may give a FALSE indication when the hydraulic oil is cold.
G Speed Select Switch – This switch will allow the operator to select the transport speed limit while the scrub system is enabled thereby allowing scrubbing at a higher
rate of speed. This option can be disabled if desired. See the programming section for details.
The transport and scrub speed limits can be programmed using a Curtis handheld programmer. Refer to the electrical section in this manual for details.
* Speed Select Switch Indicator: This indicator will be green if a scrub mode has been selected and the faster scrub speed has been selected. This indicator will be off
if the Speed Select Switch has been turned OFF.
SCRUB SYSTEM
H Scrub Pressure Decrease Switch – If the scrub system is off, pressing this switch will cause the following to occur:
• The scrub system will be enabled with the scrub pressure set to the lightest setting and the scrub deck will be lowered
• The vacuum system will be enabled and the squeegee will be lowered
• The solution system will be enabled
• As soon as the drive pedal is moved from the neutral position the scrub brushes will start turning and the vacuum will turn on. If the direction is forward the solution fl ow
will start. If the direction is reverse, the squeegee will raise and the solution fl ow will be stopped. The scrub brushes will turn off after an adjustable delay once the drive
pedal returns to neutral. See the programming section for details.
If the scrub system is already enabled when this switch is pressed and the scrub pressure is at 2 or 3, the scrub pressure will decrease. If the switch is held, the pressure
will decrement until the minimum setting of 1 is reached.
* Scrub Pressure Decrease Indicator: The scrub pressure decrease indicator will be lit if the scrub system is enabled and the pressure is set at 1 or 2. The indicator
will be off if the scrub system is off or if the scrub pressure is set to 3.
I Scrub Pressure Increase Switch – If the scrub system is off, pressing this switch will cause the following to occur:
• The scrub system will be enabled with the scrub pressure set to the lightest setting and the scrub deck will be lowered
• The vacuum system will be enabled and the squeegee will be lowered
• The solution system will be enabled
• As soon as the throttle is moved from the neutral position the scrub brushes will start turning and the vacuum will turn on. If the direction is forward the solution fl ow will
start. If the direction is reverse, the squeegee will raise and the solution fl ow will be stopped. The scrub brushes will turn off after an adjustable delay once the drive
pedal returns to neutral. See the programming section for details.
If the scrub system is already enabled when this switch is pressed and the scrub pressure is at 1 or 2, the scrub pressure will increase. If the switch is held, the pressure
will increment until the maximum setting of 3 is reached.
* Scrub Pressure Increase Indicator: The scrub pressure increase indicator will be lit if the scrub system is on and the pressure is set at 2 or 3. The indicator will be off
if the scrub system is off or if the scrub pressure is set to 1.
J Scrub Pressure Display:
The single character display on the control panel is used as a display for the scrub pressure. If the scrub system is ON, the display will indicate the relative pressure
setting of 1, 2 or 3 otherwise it is blank. Note: This display is also used to show error codes see the main controller A1 self diagnostic test mode found in this manual
for a complete explanation.
K Solution Switch - This switch is used to turn the solution system on or off. Pressing this switch when the scrub system has been activated will alternate between on and
off. The solution fl ow will only turn on when the drive pedal is moved from the neutral position in the forward direction. The solution fl ow will turn off if the drive pedal
returns to neutral or is moved to reverse. Pressing this switch when the scrub system is off will momentarily turn the solution fl ow on to allow pre-wetting of the scrub
brushes.
* Solution System Indicator: The solution indicator will be lit if the solution is enabled. If the solution is off, this indicator will be OFF.
L Solution Tank Empty Indicator – This indicator will illuminate when the solution tank is low.
M Recovery Tank FULL Indicator – This indicator will fl ash when the recovery tank is FULL. The vacuum system is shut OFF at this point. Draining the recovery tank
will reset this indicator.
N Vacuum System Switch – This switch is used to turn the vacuum system on or off. When the vacuum is on the squeegee will lower (unless the machine is in reverse)
and when the vacuum is off the squeegee will rise. Pressing this switch will alternate between on and off. The vacuum will only turn on when the drive pedal is moved
from the neutral position. It will remain on for 10 seconds after the drive pedal returns to neutral.
The vacuum also has an automatic shutoff feature that will turn the vacuum and scrub systems off if the recovery tank becomes full. If this occurs, the recovery tank full
indicator (M) will fl ash. The vacuum shutoff delay is adjustable. See the programming section for details.
* Vacuum System Indicator: The vacuum indicator will be lit if the vacuum is enabled. It will fl ash if the vacuum is in the delayed-off condition. If the vacuum is off, this
indicator will be off.
O Scrub System OFF Switch - Pressing this switch when the unit is in a scrub mode will cause the following to occur:
• The scrub brushes will turn off
• The scrub deck will raise to the UP position
• The solution fl ow will be stopped
• The fi rst time that this button is pressed, the vacuum/squeegee system will NOT be turned off. This is so that any remaining water may be picked up without having to
turn the vacuum back on. If this button is pressed a second time (pressed after the scrub mode has been turned off) the squeegee will raise and the vacuum will shut
off after a 10 second delay.
* Scrub System OFF Indicator: This indicator will be lit if the scrub system is OFF. This indicator will be OFF if the scrub system is enabled or running.
