solution fl ow is controlled automatically. The Solution Flow Control Lever (7) should not be shut off, but is otherwise inactive. Make sure that the lever for
Valve (26) is all the way ON or all the way OFF, never in between.
The controls on the Adgressor were designed with one touch operation in mind. For single pass scrubbing the user can simply depress one switch and all
systems on the machine will be ready to go.
For most single-pass scrubbing operations, the operator should only need to use the top three switches on the control panel. These are the Scrub System
Off, Scrub Pressure Decrease, and Scrub Pressure Increase switches.
Scrub Off Switch(B) - Pressing this switch when the unit is in a scrub mode will cause the following to occur:
• The scrub brushes will turn off and the scrub deck will raise to the up position
• The solution fl ow will be stopped
• The fi rst time that this switch 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 switch is pressed a second time (pressed after the scrub system has been turned off) the squeegee
will raise and the vacuum will shut of after a 10 second delay.
• The travel speed limit will return to the transport speed setting.
Scrub Pressure Decrease Switch (D) – 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 last used 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
• The travel speed will be limited to the scrub speed setting
• 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.
If the scrub system is already enabled when this switch is pressed, the scrub pressure will decrease. If the switch is held, the pressure will decrement until the
minimum setting of 1 is reached.
Scrub Pressure Increase Switch (F) – 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 last used 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
• The travel speed will be limited to the scrub speed setting
• 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.
If the scrub system is already enabled when this switch is pressed, the scrub pressure will increase. If the switch is held, the pressure will increment until the
maximum programmed limit is reached (default = 3).
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 fl ow off (to the scrub deck). The squeegee will be lowered to provide easier access to the recovery hose. NOTE:
automatic shutoff of the vacuum motor when the recovery tank is full is disabled when the wand is enabled. The fl oat 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 service manual 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 drive pedal is in the forward position. 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. The shutoff threshold can also be adjusted if necessary. 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 fl ow will only turn on when the throttle is moved from the neutral position in the forward direction. The solution fl ow 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 fl ow on to allow pre-wetting of the scrub brushes.
In general, the following guidelines apply to the control panel indicators:
A steady red indicator means that the function is inhibited for some reason. For example, if the scrub system is off and the operator is not on the seat, the
scrub system indicator will be red indicating that the system cannot be turned on until the operator is on the seat.
A fl ashing 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 a scrub mode is selected and the throttle is in
neutral, the scrub system, vacuum, and solution indicators will all be yellow indicating that the systems are enabled and ready to turn on when the throttle is
moved to forward or reverse.
A green indicator means that the particular system is on.
A fl ashing green indicator means that the particular system is in a delayed-off condition. An example of this is when a scrub mode is selected and the
throttle goes from forward or reverse to neutral. When this happens the vacuum indicator will fl ash green indicating that the vacuum is still on but that it will
be turning off after the delay period.
Scrub Off Indicator (A):
• This indicator will be green if the scrub system is off and ready to be activated.
• This indicator will be red if the scrub system has been turned off and the scrub deck is not up yet, or if the scrub deck is up and there is no weight on
the seat.
• This indicator will fl ash red if there is a fault in the scrub system.
• This indicator will be off if the scrub system has been activated.
Scrub Pressure Decrease Indicator (C):
• This indicator will be yellow if the scrub system is enabled but the drive pedal is at neutral and the current scrub pressure is at 2 or more.
• This indicator will be green if the scrub system has been turned on, the current scrub pressure is at 2 or more and the machine is moving in either
direction.
• This indicator will be off if the scrub system has been turned OFF or the scrub pressure is set at 1.
Scrub Pressure Increase Indicator (E):
• This indicator will be yellow if the scrub system is enabled but the drive pedal is at neutral and the current scrub pressure is at 2 or less.
• This indicator will be green if the scrub system has been turned on, the current scrub pressure is at 2 or less and the machine is moving in either
direction.
• This indicator will be off if the scrub system has been turned OFF or the scrub pressure is set at 3.
Scrub Pressure/Hourmeter Display (G):
The single character display on the control panel is primarily used as a display for the scrub pressure. This display is also used to display the machine hours
and any control system fault codes.
If any of the systems on the machine are on or if the throttle is not in neutral, the display will indicate the scrub pressure setting (1-3). If the scrub system is
off the display will indicate 0.
Upon power-up or if the machine has been idle for at least ten seconds with all systems turned off, the display will indicate the machine hours. The format for
the display of the hours is as follows:
Example 123.4 hours
• The display will indicate 1 followed by a short blank period
• The display will indicate 2 followed by a short blank period
• The display will indicate 3 followed by a short blank period
• The display will indicate _ followed by a short blank period, this is used as a decimal point to indicate tenths of hours
• The display will indicate 4 (tenths) followed by a long blank period
• The display sequence will repeat
If an overload fault occurs, the display will indicate the associated error code immediately. If an open or short fault occurs, the error will be displayed if the
scrub system is not active. The format for the display of error codes is as follows:
Example: error code 6, and error code 18
• The display will indicate E followed by a short blank period
• The display will indicate 0 followed by a short blank period
• The display will indicate 6 followed by a slightly longer blank period
• The display will indicate E followed by a short blank period
• The display will indicate 1 followed by a short blank period
• The display will indicate 8 followed by a slightly longer blank period
• The display sequence will repeat
NOTE: If a speed control fault occurs (error code 3) the wand indicator will fl ash the fault code produced by the Curtis speed control. Refer to the service
manual troubleshooting section for details.
• This indicator will be green if the Wand Switch has been turned ON.
• This indicator will be off if the Wand Switch has been turned OFF.
Speed Selector Indicator (M):
• 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.
Vacuum System Indicator (P):
• This indicator will be green if the vacuum is on.
• This indicator will fl ash green if the vacuum is in the 10 second delayed-off condition.
• This indicator will be yellow if the vacuum is enabled but the drive pedal is in neutral.
• This indicator will fl ash yellow if there is a vacuum system fault.
• This indicator will be off if the vacuum is disabled and turned off.
Solution System Indicator (Q):
• This indicator will be green if the solution is on.
• This indicator will be yellow if the solution is enabled but the drive pedal is in neutral.
• This indicator will fl ash yellow if there is a solution system fault.
• This indicator will be off if the solution is disabled and turned off.
Power Saving Sleep Function
The Adgressor is equipped with a battery saving feature that will turn all of the machine systems and accessories off if the machine is left in an idle state for a
preset period of time. This sleep mode will only occur if the operator is not on the seat and the wand function is not in use. The sleep mode is indicated by a
short duration green fl ashing scrub system off indicator. The sleep function is automatically cancelled when the operator sits on the seat or any of the control
switches are pressed. The sleep delay period is adjustable from 10 to 90 minutes in 10 minute increments. The default period is 10 minutes. It can also be
disabled. Refer to the service manual for changing the delay period.
The battery condition indicator (J) consists of three lights, a green (G), a yellow (Y), and a red (R). The voltage indication will change based on the cutoff
level (standard or alternate) selected in the control unit. The battery voltage ranges for the various indications are listed below:
Standard Alternate
Green 34.00+ 34.50+
Green & Yellow 33.00-33.99 34.00-34.49
Yellow 32.00-32.99 33.50-33.99
Yellow & Red 31.50-31.99 33.00-33.49
Red 31.00-31.49 32.50-32.99
Flashing Red/Cutoff <31.00 <32.50
NOTE: Refer to service manual for selection of alternate cut-off level. Once the low voltage cutout level has been reached (fl ashing red indicator) the
batteries must be FULLY recharged to reset the battery condition indicator. The scrub system will not function until the indicator has been reset.

INSTALL THE BRUSHES (CYLINDRICAL SYSTEM)
CAUTION!
Turn the key switch off (O) and remove the key, before changing the brushes, and before opening any access panels.
1 Make sure the Key Switch (J) is off (O). To access the brushes, swing both side skirt assemblies open. Note: The skirts are held in place by a large cotter pin on each
side, remove the pins and swing the skirt assemblies out of the way. Loosen the black knobs (one on each side) on top of the idler assemblies and remove the idler
assemblies. Slide the brush into the housing, lift slightly, push and turn until it seats. Re-install the idler assemblies, close the skirt assemblies and secure with cotter pins.
1 Make sure the Squeegee (19) is up (O) and the Key Switch (J) is off (O). Hold the squeegee tool so that the curved ends point forward, then slide the
squeegee tool onto the Mount (A) (See Figure 2).
2 Hand tighten the Thumb Nuts (B) and then connect the vacuum hose to the Squeegee Tube (C) (vacuum hose should loop to the right).
FILL THE SOLUTION TANK
Read the cleaning chemical label and fi gure the proper amount of chemical to mix for a tank that holds 40 US gallons (151 liters).
Open the Solution Tank Cover (2), then fi ll the tank 1/3 full of water, add the cleaning chemical, then fi ll the tank to 7.62cm (3 inches) from the top of the tank
opening (fi ll to bottom of the wall in tank opening).
CAUTION!
Use only low-foaming, non-fl ammable liquid detergents intended for automatic scrubber machine applications.
Be sure you understand the operator controls and their functions.
While on ramps or inclines, avoid sudden stops when loaded. Avoid abrupt sharp turns. Use low speed down hills. Clean only
while ascending (driving up) the ramp.
To Scrub...
Follow the instructions in preparing the machine for use section of this manual.
1 While seated on the machine, adjust the seat and steering wheel to a comfortable operating position using the adjustment controls (25) and (5).
2 Turn the Master Key Switch (J) ON (I). This will display the control panel indicator lights, reference the Battery Condition Indicator (K) and Hour Meter
(G).
3 Release the Parking Brake (6). To transport the machine to the work area, apply even pressure with your foot on the front of the Drive Pedal (8) to go
forward or the rear of the pedal for reverse. Vary the pressure on the foot pedal to obtain the desired speed.
4 Adjust the Solution Flow Control Valve Lever (7) to about 1/4 to 1/3 open position. Note the adjustment can be changed to allow variable solution fl ow
for different types of fl oors to be scrubbed. Example: A rough or absorbent fl oor surface, such as unfi nished concrete, will require more solution than a
smooth fi nished fl oor.
NOTE: For a consistent reduced fl ow of solution; open the Solution Flow Control Valve Lever (7) all the way and then turn ON the Smart Solutions™ /
ECO Solution™ valve.
5 Press the Solution Switch (R) and hold for 5 seconds. This is done to pre-wet the fl oor. Note: This will help prevent scarring of the fl oor surface when
starting to scrub with dry brushes.
6 Press the Scrub Pressure Decrease Switch (D) or the Scrub Pressure Increase Switch (F) to activate the scrub system. Note: refer to the Functional
Description of Control Switches section for a more detailed explanation of these and other control panel functions.
7 When the Scrub Pressure Decrease Switch (D) or the Scrub Pressure Increase Switch (F) are selected, the brushes and squeegee are automatically
lowered to the fl oor. The machine’s scrub brush rotation, solution system fl ow and vacuum starts when the Drive Pedal (8) is activated. Note: When
operating the machine in reverse, only the brushes will rotate, the solution is automatically shut off to conserve the solution usage.
8 Begin scrubbing by driving the machine forward in a straight line at a normal walking speed and overlap each path by 2-3 inches (50-75 mm). Adjust
when necessary the machine speed and solution fl ow according to the condition of the fl oor.
CAUTION!
To avoid damaging the fl oor, keep the machine moving while the brushes are turning.
9 When scrubbing, check behind the machine occasionally to see that all of the waste water is being picked up. If there is water trailing the machine, you
may be dispensing too much solution, the recovery tank may be full, or the squeegee tool may require adjustment.
10 For extremely dirty fl oors, a one-pass scrubbing operation may not be satisfactory and a “double-scrub” operation may be required. This operation is
the same as a one-pass scrubbing except on the fi rst pass the squeegee is in the up position (press the Vacuum Switch (O) to raise the squeegee).
This allows the cleaning solution to remain on the fl oor to work longer. The fi nal pass is made over the same area, with the squeegee lowered to pick
up the accumulated solution.
11 The recovery tank has an automatic fl oat shut-off to prevent solution from entering the vacuum system when the recovery tank is full. When the fl oat
shut-off is activated, the control system will shut down the scrub, vacuum and solution systems. The Scrub Pressure / Hourmeter Display (G) will display
“FULL”. To clear the display, press the Scrub OFF Switch (B), Scrub Pressure Decrease Switch (D), Scrub Pressure Increase Switch (F) or the Vacuum
Switch (O). When the fl oat closes, the recovery tank must be emptied. The machine will not pick up water with the fl oat closed. NOTE: If the control
repeatedly gives a full indication when the tank is not full, the automatic shut-off feature can be disabled, have a qualifi ed service technician refer to the
service manual to perform this function.
12 When the operator wants to stop scrubbing or the recovery tank is full, press the Scrub OFF Switch (B) once. This will automatically stop the scrub
brushes and solution fl ow and the scrub deck will raise UP. NOTE: the vacuum/squeegee system will not be turned off when the switch is only pressed
once, this is to allow any remaining water to be picked up without turning the vacuum back on. Press the switch a second time and the squeegee will
raise and the vacuum will stop after a 10 second delay.
13 Drive the machine to a designated waste water “DISPOSAL SITE” and empty the recovery tank. To empty, pull the Drain Hose (21) from its rear
storage area, then remove the plug (hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled fl ow of waste water). Refi ll
the solution tank and continue scrubbing.
Steps to follow in fi tting the machine with optional attachments for wet vacuuming.
1 Disconnect the recovery hose from the squeegee. Connect the coupler and hose from the wand kit to the recovery hose.
2 Attach suitable wet pick-up tools to the hose. (An optional Wand Kit PN56314307 is available from Nilfi sk-Advance).
3 Turn the Master Key Switch (J) ON, next press the Wand Switch (I). The vacuum motor and pump will run continuously until the switch is pressed
again to turn them OFF. NOTE: If the control repeatedly gives a full indication when the tank is not full, the automatic shut-off feature can be disabled,
have a qualifi ed service technician perform this function.
AFTER USE
1 When fi nished scrubbing, press the Scrub Off Switch (B) twice, this will automatically raise, retract and stop all the machine systems (brush, squeegee,
vacuum & solution). Then drive the machine to a service area for daily maintenance and review of other needed service up keep.
2 To empty the solution tank, remove the Solution Drain Hose (4) from it’s storage clamp. Direct the hose to a designated “DISPOSAL SITE” and remove
the plug. Rinse the tank with clean water.
3 To empty the recovery tank, pull the Recovery Tank Drain Hose (21) from its storage area. Direct the hose to a designated “DISPOSAL SITE” and
remove the plug (hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled fl ow of waste water). Rinse the tank with
clean water.
4 Remove the brushes or pad holders. Rinse the brushes or pads in warm water and hang up to dry.
5 Remove the squeegee, rinse it with warm water and re-install on mount.
6 Remove the hopper on cylindrical systems and clean thoroughly. Remove from either side of the machine by opening the skirt and tilting the hopper up
and away from housing, then pull out.

NOTE: Refer to the Service Manual for more detail on maintenance and service repairs.
8 Store the machine indoors in a clean dry place. Keep from freezing. Leave the tanks open to air them out.
9 Turn the Master Key Switch (J) OFF (O) and remove the key.
LUBRICATING THE MACHINE
Once a month, pump a small amount of grease into each grease fi tting on the machine until grease seeps out around the bearings.
Grease fi tting locations are:
• Squeegee Caster Wheel Axle
• Steering Wheel Shaft Universal joint
Once a month, apply light machine oil to lubricate the:
• Steering Chain
• General Pivot Points For the Squeegee, Brush Linkage and Side Skirts
Charge the batteries each time the machine is used, or whenever the Battery Condition Meter (K) is showing a yellow , red or fl ashing red indicator light(s).
To Charge the Batteries...
1 Depress the Battery Disconnect (13).
2 Open the Battery Compartment Cover (16) to provide proper ventilation.
3 Push the connector from the charger into the Battery Connector (22).
4 Follow the instructions on the battery charger.
5 Check the fl uid level in all battery cells after charging the batteries. Add distilled water, if necessary, to bring the fl uid level up to the bottom of the fi ller
tubes.
WARNING!
Do not fi ll the batteries before charging.
Only charge batteries in a well-ventilated area.
Do not smoke while servicing the batteries.
CAUTION!
To avoid damage to fl oor surfaces, always wipe water and acid from the top of the batteries after charging.
CHECKING THE BATTERY ELECTROLYTE LEVEL
Check the electrolyte level of the batteries at least once a week.
After charging the batteries, remove the vent caps and check the electrolyte level in each battery cell. Use distilled water to fi ll the batteries to the bottom of
the fi ller tube.
Do not over-fi ll the batteries!
CAUTION!
Acid can spill onto the fl oor if the batteries are overfi lled.
Tighten the vent caps. If there is acid on the batteries, wash the tops of the batteries with a solution of baking soda and water (2 tablespoons of baking soda
to 1 quart of water).
If the squeegee leaves narrow streaks or water, the blades may be dirty or damaged. Remove the squeegee, rinse it under warm water and inspect the
blades. Reverse or replace the blades if they are cut, torn, wavy or worn.
To Reverse or Replace the Rear Squeegee Wiping Blade...
1 See Figure 3. Raise the squeegee tool off the fl oor, then unsnap the Center Latch (A) on the squeegee tool.
2 Remove the Tension Straps (B).
3 Slip the rear blade off the alignment pins.
4 The squeegee blade has 4 working edges. Turn the blade so a clean, undamaged edge points toward the front of the machine. Replace the blade if all
4 edges are nicked, torn or worn to a large radius.
5 Install the blade, following the steps in reverse order and adjust the squeegee tilt.
To Reverse or Replace the Front Squeegee Blade...
1 Raise the squeegee tool off the fl oor, then loosen the (2) Thumb Nuts (C) on top of the squeegee and remove the squeegee tool from the mount.
2 Remove both rear Tension Straps fi rst.
3 Remove all the wing nuts that hold the front blade in place, then remove tension strap and blade.
4 The squeegee blade has 4 working edges. Turn the blade so a clean, undamaged edge points toward the front of the machine. Replace the blade if all
4 edges are nicked, torn or worn to a large radius.
5 Install the blade, following the steps in reverse order and adjust the squeegee tilt.
SQUEEGEE ADJUSTMENT
There is just one squeegee tool adjustment possible, angle.
Adjusting the Squeegee Angle
Adjust the squeegee angle whenever a blade is reversed or replaced, or if the squeegee is not wiping the fl oor dry.
1 Park the machine on a fl at, even surface and lower the squeegee. Then drive the machine forward enough to have the squeegee blades fold over to
the rear.
2 Loosen the Lock Wing Nut (D) (hand tightened). This secures the squeegee mount angle from easily vibrating out of adjustment.
3 Turn the Adjustment Knob (E) to tilt the tool forward or backwards, until the rear squeegee wiping blade touches the fl oor evenly across its entire width.
4 Re-tighten by hand the Lock Wing Nut (D).
The side skirt’s function is to channel the waste water to the squeegee, helping contain the water within the machines cleaning path. During normal use the
blades will wear in time. The operator will notice a small amount of water leaking out underneath the side skirts. A height adjustment can easily be made to
lower the blades so that all the water can be pick-up by the squeegee.
To reverse or replace the scrub system side skirt(s) ...
1 See Figure 4. Loosen the (2) side skirt Retainer Knobs (A) (2 per side) and pull the Skirt Assemblies (B) off from the scrub deck.
2 Remove all the hardware that holds the blades to the skirt housings.
3 Replace the blades as a set if they are nicked, torn or worn beyond their ability to be adjusted.
4 Reinstall the skirt housing assemblies onto the machine and adjust the blade for proper contact to the fl oor when the brush deck is placed in the scrub
position.
SIDE SKIRT HEIGHT ADJUSTMENT (DISC SYSTEM)
1 The side skirt housing knob retainer screw studs have leveling Adjuster Collars (C), that are to be raised or lowered to compensate for blade wear.
2 To adjust, remove the Skirt Assemblies (B) from the Scrub Deck (D) to access the Adjuster Collars (C). Adjustment Tip: The skirts Retainer Knobs (A)
can be loosened with skirts left on and the Adjuster Collars (C) rotated by reaching under the skirt housing.
3 Turn the Adjuster Collars (C) (Up or Down) to where the blades just fold over enough when scrubbing that all the waste water is contained inside the
skirting. Note: Make small adjustments to obtain good blade wiping. Do not lower the blades too much to where they fold over excessively and cause
unneeded blade wear.
The side skirts function is to channel the waste water to the squeegee, helping contain the water within the machines cleaning path. During normal use the
blades will wear in time. The operator will notice a small amount of water leaking out underneath the side skirts. Skirt height adjustment is automatic on this
system. The skirt assemblies should move up and down freely for proper operation.
To replace the scrub system side skirt(s) ...
1 See Figure 5. Remove the (2) (A) Cotter Pins and swing the Skirt Assemblies open. Remove the (B) Screws and Nuts, remove the Skirts and replace.
