Vacuum Button (E) - This button is used to select the mode of operation for the vacuum system. There are 3 modes of operation for this system.
These modes are OFF, AUTO, ON. Following is a description of each mode and how they are selected.
OFF MODE: In this mode the vacuum is off. As mentioned in the following, when the scrub ON button (G) is pushed, the vacuum system will be
placed in the AUTO mode. If it is desired to double-scrub (scrub without recovering the solution) the vacuum system can be turned off by pressing
this button at any time.
AUTO MODE: This mode is automatically selected when the scrub ON button (G) is pushed. The vacuum will turn on when the drive paddle (3)
is moved forward or reverse. Once the scrub system has been turned OFF, the vacuum will remain ON. To turn the vacuum OFF, press and release
the vacuum button or the scrub OFF button
(H) . This will start a ten second delay to allow pick-up of remaining solution. This mode can be selected
independently of the scrub mode by pressing and releasing the vacuum button.
ON MODE: In this mode the vacuum will be on regardless of the drive paddle (3) position. This mode is selected by pressing and holding the
Vacuum Button (E) for approximately 1.5 seconds. The vacuum mode must first be OFF before entering this mode . This mode is included in the
event an external wand is to be used with this machine or if the operator wants to clean the squeegee using the vacuum hose.
Scrub ON / Pressure Increase Button (G) - Pressing the scrub ON button will enable the scrub system and set the scrub pressure to the last
selected value. The status display (A) will display the scrub pressure setting. This is indicated by a number. Subsequent presses of the scrub
ON button will step the pad pressure setting through the allowable range up to the maximum value of 9. The following will occur when this button
is pressed:
•
The scrub deck will be lowered
• The vacuum and solution systems will be enabled (vacuum and solution modes = AUTO)
• As soon as a direction is commanded by the Drive Paddle (3) (forward or reverse) the brushes will start turning and the vacuum and solution
will turn on.
Scrub OFF / Pressure Decrease Button (H) - Momentarily pressing this button will step the pad pressure down to a minimum value of 1. Pressing
and holding this button for approximately 1/2 second when the unit is in scrub mode will cause the following to occur:
•
The status display (A) will indicate “0”
• The scrub brushes will turn off
• The scrub deck will raise to the UP position
• The solution flow will be stopped and the last used pad pressure will be saved
• The first time that this button is pressed, the vacuum 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
vacuum will shut off after a 10 second delay.
NOTE: Reducing the pad pressure to “1” and then pressing this button one more time will also turn the scrub system OFF. In this case the last
used pressure will not be saved.
NOTE: If the optional Brush Remove Feature is installed, it functions as follows:
• To activate the automatic brush removal feature, the scrub deck must be in the UP position and the Drive paddle must be in neutral.
• Press and hold the Scrub OFF / Pressure Decrease Button (H) for 1 second. The Scrub OFF Indicator (I) will turn RED and the brush motors
will turn on briefly. The motors will then stop abruptly which will cause the brushes to fall off.
DESCRIPTION OF INDICATORS ON THE CONTROL PANEL:
In general, the following guidelines apply to the control panel indicators:
A steady red indicator means that the function is inhibited for some reason .
A flashing red or yellow indicator means that a fault has occurred in the particular system . An example of this would be an over-current fault.
A yellow indicator means that the particular function has been enabled but is not currently on . For example, if the scrub system is activated and
the Drive Paddle (3) is in neutral, the vacuum and solution indicators will all be yellow indicating that the systems are enabled and ready to turn
on when the Drive Paddle (3) is moved to forward or reverse.
A green indicator means that the particular system is on .
A flashing green indicator means that the particular system is in a delayed-off condition . An example of this is when the scrub system is activated
and the Drive Paddle (3) goes from forward or reverse to neutral. When this happens the vacuum indicator will flash green indicating that the vacuum
is still on but that it will be turning off after the delay period.
Scrub Pressure/Hourmeter Display (A):
• The scrub pressure/hourmeter display will scroll the hourmeter information only if all of the systems are turned off and the throttle has been
in neutral for at least ten seconds. The hourmeter information will also be displayed immediately once the key switch has been turned on.
• If any of the systems are turned on or the throttle is in forward or reverse, the display will show the relative scrub pressure value (1-9) or
0 if the scrub system is off. This value is a relative indication of scrubbing effort. It is not an absolute indication of the scrub pressure.
Solution System Indicator (C):
• This indicator will be green if the solution is on.
• This indicator will be yellow if the solution is enabled but not turned on.
• This indicator will be off if the solution is disabled and turned off.
