General Information
Scrub Pressure Increase Switch (F) – If the scrub system is off, pressing this switch will cause the following to occur:
Pressure Increase / Decrease Mode (Factory Default)
•
The scrub system will be enabled with the scrub pressure set to the last used setting and the scrub deck will be lowered
o
The vacuum system will be enabled and the squeegee will be lowered
o
The solution system will be enabled
o
The travel speed will be limited to the scrub speed setting
o
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
o
forward the solution flow will start. If the direction is reverse, the squeegee will raise and the solution flow will be stopped.
The scrub pressure increase indicator will be green if the scrub system is on and the pressure is set at 2 or 3. The indicator will be off if
o
the scrub system is off or if the scrub pressure is set to minimum. The indicator will be yellow if the scrub system has been enabled but the
throttle is in neutral.
Fixed Pressure Mode
•
The scrub system will be enabled with the scrub pressure set to the heavy setting and the scrub deck will be lowered
o
The vacuum system will be enabled and the squeegee will be lowered
o
The solution system will be enabled
o
The travel speed will be limited to the scrub speed setting
o
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
o
forward the solution flow will start. If the direction is reverse, the squeegee will raise and the solution flow will be stopped.
The Scrub Pressure Increase Indicator (E) will be green if the scrub system is on and the heavy pressure has been selected. The indicator
o
will be off if the scrub system is off. The indicator will be yellow if the scrub system has been enabled at the heavy pressure setting but the
throttle is in neutral.
If the light scrub pressure setting is selected, pressing this switch will select the heavy scrub pressure. If the heavy scrub pressure is
o
already selected, pressing this switch will have no effect.
Light / Heavy Scrub Mode
•
The scrub system will be enabled with the scrub pressure set to the last used heavy pressure setting and the scrub deck will be lowered
o
The vacuum system will be enabled and the squeegee will be lowered
o
The solution system will be enabled
o
The travel speed will be limited to the scrub speed setting
o
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
o
forward the solution flow will start. If the direction is reverse, the squeegee will raise and the solution flow will be stopped.
The Scrub Pressure Increase Indicator (E) will be green if the scrub system is on and the heavy pressure has been selected. The indicator
o
will be off if the scrub system is off. The indicator will be yellow if the scrub system has been enabled at the heavy pressure setting but the
throttle is in neutral.
If the light scrub pressure is active, pressing this switch will cause the pressure to return to the last used heavy scrub pressure setting. If the
heavy scrub pressure is already selected when this switch is pressed, the scrub pressure will increase up to the maximum limit programmed for
the heavy scrub pressure. The pressure will then roll-over to the minimum value programmed for the heavy scrub mode.
Wand Switch (I) – This switch is used when an external scrub wand is used. Pressing this switch will turn the vacuum on continuously without
regard to the throttle position. It will also enable the optional solution pump. If the scrub system was on it will be turned off. This includes turning off
the scrub brushes and raising the scrub deck, turning the solution flow off (to the scrub deck) and raising the squeegee. NOTE: automatic shutoff
of the vacuum motor when the recovery tank is full is disabled when the wand is enabled. The float in the recovery tank will still prevent water from
entering the vacuum motor, but the motor will not shut off.
Key Switch (J) – Main power switch
Speed Select Switch (L) – 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 Curtis Speed Control manual section for details.
Horn Switch (N) – This switch will sound the horn as long as the switch is held.
The horn also functions as an automatic back-up alarm when the throttle is moved to the reverse position. The volume of the back-up alarm
is programmable. It can also be programmed to provide an annunciation feature that will sound whenever the machine is in motion. See the
programming section for details.
Vacuum Switch (O) – 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 raise. Pressing this switch will alternate between on and off. The vacuum will only turn
on when the throttle is moved from the neutral position. It will remain on for 10 seconds after the throttle 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. This feature can be disabled if desired.
See the programming section for details.
Solution Switch (R) - 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 flow will only turn on when the throttle is moved from the neutral position in the forward direction. The
solution flow will turn off if the throttle returns to neutral or is moved to reverse. Pressing this switch when the scrub system is off will momentarily
turn the solution flow on to allow pre-wetting of the scrub brushes.
