MACHINE PREPARATION
BATTERY POWER LEVEL INDICATORS
The battery power level gage is located on the upper control panel. The gage has a series of LEDs to indicate the amount of power left in the
batteries. When the batteries have a full charge, all LEDs are lit. As the batteries are discharged, the LEDs will begin to go out from right to
left. To maximize the life of the batteries, do not allow the LEDs to go beyond the discharge level as described below. To maximize the life of the batteries, only recharge the batteries when the machine is operated for a total of 30 minutes or more and always
recharge the batteries immediately after usage when LEDs are indicating charging is required as described below.
BATTERY POWER LEVEL INDICATOR - TRACTION DRIVE MODELS
The battery power level gage is located on the upper control panel. The gage has red, yellow and green
LEDs to indicate the amount of power left in the batteries.
Recharge lead
acid batteries
Recharge AGM
batteries
On lead acid battery-equipped units, when the discharge level reaches the first red LED, it is a good time
to finish your scrubbing application and recharge the unit. If you do choose to continue scrubbing, when
the last red LED begins to flash, the unit will shut down the brush motor but leave the vacuum and
traction drive operational to perform final water recovery and transport back to storage. This function
not only serves as an indicator that your battery level has reached a point where recharging is required,
but also protects the batteries from being fully discharged.
AGM battery-equipped units should not be used after the last yellow LED goes out leaving only red
LEDs. Using the unit beyond this point can reduce the life of the batteries.
NOTE: The traction drive battery power level gage also displays fault codes. The LEDs will flash specific
fault codes if a fault is detected. See Troubleshooting section for LED fault codes.
BATTERY POWER LEVEL INDICATOR - PAD/BRUSH ASSIST MODELS
The battery power level gage is located on the upper control panel. The gage has a series of yellow
LEDs to indicate the amount of power left in the batteries. When batteries are fully charged, all LEDs are
lit. As the batteries discharge, the LEDs will begin to go out from right to left.

On lead acid battery-equipped units, when the discharge level reaches the last, lit LED (2nd in from left)
it is a good time to finish your scrubbing application and recharge the unit. If you do choose to continue
scrubbing, when last LED begins to flash, the unit will shut down the brush motor but leave the vacuum
operational to perform final water recovery. This function not only serves as an indicator that your
battery level has reached a point where recharging is required, but also protects the batteries from being
fully discharged. AGM battery-equipped units should not be used after there are only two LEDs lit. Using the unit beyond
this point can reduce the life of the batteries.

SOLUTION TANK
To prepare the machine for cleaning, the unit must be filled with cleaning solution.
1
Water and cleaning agent can be added to the S-20/S-24XM’s rear hose fill port located to the left of
the control panel.
2
There is also a front fill port that is able to accept hose or bucket filling.
1
Liquid detergent should be added to the tank in the concentration and manner specified by the
manufacturer for an eleven (11) gallon solution tank. The formation of excess foam could damage the
vacuum motor, so be sure to use only the correct amount of detergent. Water temperature should not
exceed 120°F (50°C).
Rear hose fill port
NOTE: Always use low-foam detergent. Introduce a small amount of defoaming liquid in the recovery tank
before starting work to prevent foam from being generated. Never use pure acids.

3
It is easy to gage the solution level by watching the fog-free solution sight gage at the rear of the
machine. Additionally, marks on the tank provide solution level indicators as a guide.
4
The bottom of the front fill port is also a full level indicator. Once you are able to see water at the base
of the opening, you have reached the full level.
5
The sight gage hose performs double-duty as the solution drain hose as well. You simply slide the
hose off the press fitting and lower the hose to a drain or mop sink.

MACHINE PREPARATION
ATTACHING YOUR PAD DRIVER OR BRUSH TO THE S-20/S-24XM - DISK HEAD
The pad driver(s) or brush(es) are attached by using the automatic on/off system. This valuable ingenuity removes the need for operators to
kneel or strain to attach the pad driver or brush.
First, start by placing the pad driver or brush on the floor in front of the S-20/S-24XM scrubber.
1
Turn the unit on using the power key switch.
2
Push or drive it into position so that the unit’s scrub head is centered over the pad driver(s) or brush(es).
3
Utilize the foot pedal to lower the scrub deck down onto the pad driver or brush by depressing the pedal while shifting it to the right.
Once clear of the lower notch, lifting your foot will lower the scrub deck. Make sure that the shroud completely covers the pad driver(s)
or brush(es) in the lowered position. Should the shroud be resting on a portion of the pad driver or brush, the head isn’t centered and will
not attach properly.
4
The operation is completed by quickly pulsing the activation trigger. This will “click on” the pad driver(s) or brush(es). If the pad
driver(s) or brush(es) do not quickly engage, do not continue pressing the activation trigger. Realign the scrub deck and try procedure
again. When you have the scrub deck aligned properly, you should see a noticeable drop of the scrub deck when lowered and the bristle
skirt on the shroud should almost be touching the floor.

MACHINE PREPARATION
ATTACHING YOUR PAD - ORBITAL HEAD
ATTACHING A PAD TO YOUR ORBITAL PAD DRIVER
The orbital unit can be used for daily cleaning; however it specializes in chemical-free finish removal for low-cost finish maintenance
programs. The following directions show how to prepare the machine for both applications.
For cleaning, the orbital unit is fit with a rectangular, 20 in (508 mm) x 14 in (356 mm) pad. The head comes standard with a rectangular pad
drive plate with a Mighty-Lok® connection system.
1
To attach the pad, align the front corners of the pad to the front corners of the orbital drive plate and press to attach.
2
Use the foot pedal to lower the scrub deck down onto the pad ensuring alignment from front-to-back and side-to-side.
3
When the head is properly set onto the pad, you are ready for cleaning.
1
Align the front corners of the pad
and press to adhere
2
3
Lower the scrub head using the
foot pedal
For chemical-free finish removal, it requires the addition of a specialized surface
preparation pad. The application still requires the attachment of a traditional
cleaning pad first. This pad acts as a “backer pad” which compensates for low
and high spots in the floor.
4
Align the Velcro pad retainer along one length of the red, backer pad and press
down. This will leave a 2” gap along one side of the backer pad. Then place
the surface prep pad on top of the pad retainer, centering it from front-to-back
& side-to-side with the red pad. The 2” gap left by the pad retainer needs to be
at the front of the machine so that water can fully saturate the pad. Align your
pad assembly with all corners of the pad driver and press upward. The red
backer pad should be in closest contact with the pad driver.
5
Finish the operation by using the foot pedal to lower the scrub deck down onto
the surface preparation pad, once again ensuring alignment from front-to-back
and side-to-side. When the head is properly set onto the pad, you are ready
for your finish maintenance program.

MACHINE OPERATION
OPERATIONAL CONTROLS
The machine operation and controls were designed to minimize operator training and decrease the need for adjustments during operation. Additionally, once in operation, Pacific Floorcare’s goal was to provide an ergonomic, easy to use system. Due to this focus, the S-20/
S-24XM’s key operational controls are all within reach so that the operator doesn’t have to remove their hands to perform the operation - a
key to safe, trouble-free, highly productive cleaning.
TURNING THE UNIT ON/OFF
The machine is powered on through a key switch on the upper control panel. Turn the key to the ON
position. You will see the battery meter on the left side of the upper control panel light up to show the
battery charge level.
The key switch is a proven way to eliminate unwanted operation. Simply remove the key and safely store it
away when you have completed scrubbing.
Transaxle drive unit key switch
shown above
SETTING DESIRED SOLUTION FLOW RATE
The next step is to set the unit to the desired solution flow. This control feature is located at the lower rear
of the machine and can be adjusted from low to high flow spanning a range of 0 to 0.5 gallons (1.9 L) per
minute.
Solution flow adjustment knob
15
MACHINE OPERATION
OPERATIONAL CONTROLS
Once the machine is powered on and the solution flow is set, it takes three
simple steps to operate the machine: lower the scrub deck, lower the
squeegee and engage the activation trigger. These steps are visually shown
on the lower control panel by the S-20/S-24XM’s “1, 2, 3-Step” on-board operation guide. Following are the detail steps of how scrubbing and recovery
functions are activated.
On-board “1, 2, 3-Step” operation guide
LOWERING THE SCRUB DECK
The scrub deck is lowered using the foot pedal at the rear of the unit.
Place your foot on the pedal and depress the lever while shifting it to the right. Once clear of the lower notch, lifting your foot will lower
1
the scrub deck into the operating position.
The S-20/S-24XM has two down pressure settings. The disk unit has settings of 60 and 90 lb (27 and 40 kg) and the orbital unit has
2
settings of 75 and 100 lb (34 and 45 kg). When the unit is set into operating position with the foot pedal, it is in the lower down pressure position. This position is typically used for daily cleaning of normal soils. However, should you have tough soils or want to perform
chemical-free finish removal, engage the higher down pressure setting by lifting the foot pedal lever to the upper notch position. To
disengage high down pressure, simply lift and shift the lever to the right and lower into normal operating position.

To begin scrubbing, engage the handle trigger. The trigger activates solution flow, the brush motor and traction drive, if equipped. This
unique, ergonomic design accommodates different operator heights by allowing the user to activate the trigger from any position on
the handle.
The speed control and reverse switch on the traction drive models are purposely located so that the operator doesn’t have to let go of
the machine with either hand to perform the function. Speed control is easily thumb adjusted and the reverse can be depressed with
your fingers on the back side of the control housing.
This one-handed reverse feature allows the operator to lift the squeegee with the other hand – a small element with big rewards when in
tight spaces.

MAINTENANCE
END OF SHIFT
Once you’ve completed your daily scrubbing, project work or finish maintenance, proper end of use maintenance can greatly extend the
machine’s life, improve performance, enhance sanitization and lower the machine’s long-term operational costs. There are four key areas we
will review and demonstrate: the recovery tank, squeegee assembly, battery maintenance and charging, ending with pad and brush
maintenance.
RECOVERY TANK
At the end of the job, the recovery tank needs to be emptied and rinsed out. To drain the recovery tank, utilize the recovery tank drain hose
at the rear of the machine.
The drain hose has a press-fit cap that is removed for the draining process.
1
2 The hose is also equipped with a restriction collar that can be bent or squeezed to reduce splashing and spraying during the operation.
3
As the recovery tank drains, lift the recovery tank lid to the fully open position. When almost empty, begin to rinse out the sediment
from the bottom of the tank with a clean water hose. After the tank is thoroughly rinsed and drained, leave the tank lid open to dry.
4
This is a great time to inspect and clean the vacuum mesh filter screen and ball float system. This can be removed for cleaning by
unscrewing the filter screen and rinsing it with a hose or faucet.
The full access tank is designed for periodic deep cleaning and sanitizing. Once thoroughly rinsed, the operator can use a cleaner and
sanitizer with a cloth or sponge to completely sanitize the recovery tank. This reduces the mold and mildew that can form over time.

SQUEEGEE ASSEMBLY
The squeegee system is crucial to high-performance cleaning. It is the last thing that touches the floor so proper maintenance is important
for making it perform at its peak.
1
Remove the squeegee assembly from the machine by loosening the easy-grip knobs and detaching the recovery hose at the back of the
machine. Take the squeegee to a drain or utility sink and thoroughly rinse the underside of the squeegee frame and squeegee blades.
Make sure that all particles and debris have been removed. Inspect the neck of the squeegee assembly for debris. If found, clear the
debris and rinse it out.
2
Inspect the front and rear squeegee blades. If the blade edges are not clearly defined or worn halfway through the thickness of the
blade, then it is time for replacement or to be flipped to another edge. The S-20/S-24XM’s squeegee blades have four usable edges.
3
Blade exchange is completely tool-free for fast, easy maintenance. To remove the rear blade, release the over-center latch and slide the
squeegee retainer off the hook on the other side.
4 The blade can be removed for replacement or flipped length wise or top to bottom to utilize another blade edge.
To re-attach the blade, align the blade holes with the squeegee frame guides from one end to the other. Slide the retainer over the hook and
press the retainer latch into position on the far end following the guides. Engage the latch to finish the operation.
The front-blade exchange is completed in a similar fashion to the rear blade by removing the front blade retainer, attaching a new blade using
the guides and re-engaging the squeegee retainer.
When squeegee assembly and blade maintenance is complete, re-attach the squeegee assembly by aligning the assembly, tightening the
easy grip knobs and re-attaching the hose.

BATTERY MAINTENANCE
Based on research and experience, batteries are the number one nuisance issue and drive a high cost of ownership if not properly maintained.
With the S-20/S-24XM, you can select from two types of batteries: wet, lead acid or sealed, maintenance-free AGM.
WET, LEAD ACID BATTERY MAINTENANCE
Wet batteries, by definition, need water to store energy and protect the internal lead plates. According to the supplier, here are
important things to remember for a proper battery watering process: 1. Do not let the plates get exposed to air. This will corrode the plates
2. Do not fill the water level to the cap. This causes the battery to overflow acid, consequently losing capacity and causing a corrosive mess
3. Use distilled or deionized water only
STEP BY STEP BATTERY WATERING PROCEDURE
Battery watering frequency depends upon usage, but the best practice would be to check weekly. Batteries should be fully charged prior to
watering. Refer to the Charging segment of this manual for charging instructions. Once charging is completed, open the vent caps and look
inside the fill wells. Add distilled water until the electrolyte level is approximately 1/8 in (3.2 mm) below the bottom of the fill well. Clean and
replace the vent caps.
WARNING: Fire or explosion hazard. Batteries emit Hydrogen gas. Keep sparks and open flame away. Keep battery compartment
open when charging.
CAUTION: For safety, when cleaning batteries, wear protective gloves and eye protection. Avoid contact with battery acid.
HYDROLINK® BATTERY WATERING SYSTEM
HydroLink® is a series of specialized battery caps, tubes and a hand pump that formulates a single-point
battery watering. There is no need to check or fill individual battery cells with this accessory.
HydroLink® comes with an independent, non-mechanical water level indicator that is simple to read. A
white indicator means that the battery needs water and a black indicator means that the battery has
enough water.
After the batteries are charged and the operator has identified that the batteries are low with the indicator,
place the feed hose into a reservoir of distilled water and compress the hand-pump until it becomes hard to
squeeze. This indicates that all the battery cells are filled to the proper level.

END OF SHIFT
BATTERYSHIELDTM AUTOMATIC WET BATTERY PROTECTION SYSTEM
If your scrubber is equipped with BatteryShield technology, your scrubber will provide you “real time” notification when your wet batteries
need to be watered.
After your machine is charged and you turn the key switch on, BatteryShield will check your water levels for you. You can locate the
BatteryShield optical sensor on the HydroLink® cap on your battery pack and the LED on the back panel of your scrubber.
BatteryShield optical sensor on
Trojan battery
BatteryShield LED on back panel
HydroLink battery cap light pipe
circled above
When your LED remains unlit, it means that your batteries have an acceptable water level. If BatteryShield senses that your batteries need
to be watered, the LED will indicate this with a solid, red light and BatteryShield will not allow your brush motor to function, therefore
preventing further use of the scrubber until the batteries are filled with distilled water using the HydroLink single-point battery watering
system. After filling your batteries, cycle the key switch off then on and your BatteryShield system will be reset.
BatteryShield has been programmed to check the water levels of your batteries after a full charge, so your unit will most likely be in your
janitor’s closet or storage area but if by chance it detects low water during the cleaning operation, it will only shut down the brush
motor preventing the operator from doing any further cleaning. The vacuum motor and transaxle drive motor will still be operable so that
any remaining solution can be recovered and the unit can be transported back to an area where the batteries can be watered.
If your LED has a blinking, red light it means that a HydroLink light pipe needs to be cleaned.
CAUTION: For safety, when cleaning batteries, wear protective gloves and eye protection. Avoid contact with battery acid.
Remove the HydroLink battery cap that has the BatteryShield optical sensor attached to it. Do not remove the BatteryShield sensor from
the HydroLink cap. Use a clean, damp cloth to wipe the pointed tip and shaft of the light pipe. Snap the HydroLink cap back into place on
the battery. Cycle the key switch. The BatteryShield LED should stop blinking if light tube has been cleaned effectively. If repeated attempts
to clean the light pipe are unsuccessful, a new HydroLink cap will be required.

PAD DRIVER AND BRUSH MAINTENANCE
This portion of maintenance is simple and quick, but key to keeping your S-20/S-24XM performing at peak levels. Remove the pad driver or
brush to check for wear.
1
To remove the pad driver or brush from your disk unit, locate the automatic off switch on the lower control panel at the rear of the
machine. Depress position “A” for 1 second and then depress position “B”.
2 This will “click-off” the pad driver or brush.
3 For the orbital unit, simply pull off the pad taking care to follow proper safety precautions as indicated on your chemical product label in
regards to coming in contact with solution.
Should the pad or brush show ample wear and have reached their replacement point, simply discard the pad or brush and replace it at the
beginning of your next shift. Brushes should be replaced when the bristle length reaches 3/4 in (19 mm).
Alternatively, if not worn out, you can extend the life of your pad driver, pad or brush by rinsing out any captured debris or sediment and then
hanging it to dry between shifts - a simple step that can lower your cost to clean.

TROUBLESHOOTING
OPERATOR TOP FIVE TROUBLESHOOTING LIST
Because cleaning equipment can encounter a wide array of environments and debris, various issues can arise that can be quickly fixed with
some easy troubleshooting by the operator. Because there are so many scenarios, we’ve generated the top five troubleshooting list that
addresses the most common issues.
1. MACHINE ISN’T PICKING UP WATER OR IS LEAVING A FILM ON THE FLOOR
If your machine isn’t picking-up water, there are a few key areas of the machine to check. If the vacuum seems to have a higher pitch than normal, the ball float in the recovery tank has tripped because the recovery tank is full and needs to be drained. Once drained, check that the water recovery is working. If it is, then you’ve identified and corrected the issue.
1
If still not picking-up water, then it is likely you have a clog in the recovery hose. Start by checking the recovery hose at the lower
elbow connected to the squeegee assembly.
2
Then, check the upper elbow and the recovery tank orifice. If debris is found, clear the clog with your hands or a tool. Should you have
a hose available, rinse the recovery hose and tank orifice to ensure all the debris is removed.
3
If a clog isn’t identified in the recovery hose, check the squeegee neck by loosening the easy grip knobs, removing the squeegee
assembly and flipping it over. Clear the debris, and again, if a hose is available, rinse the squeegee opening.
4
If still not recovering properly, check your rear squeegee blade edge for wear or debris. If debris is present, clean the blade. If the edge is worn to half the blade thickness, flip to a new blade edge or order a replacement blade.
Finally, should you still have recovery issues, contact your distributor or Pacific Floorcare for technical support.

TROUBLESHOOTING
OPERATOR TOP FIVE TROUBLESHOOTING LIST
2.MACHINE RUN TIME HAS DECREASED
If the machine run time has decreased, there are three potential issues that must be checked: The charger may not be plugged in or working, the wet, lead acid batteries may need watering or the batteries need to be replaced.
First, check the charger by plugging it in.
1 If an on-board charger, check the three LEDs. If none are on, then you likely have a faulty charger and it will need to be replaced.
However, if the lights are on and the red or yellow light is on, then the batteries aren’t fully charged and the charge cycle needs to be
completed. If the green light is on, then the charger is working and the next step is to consider the batteries.
2
If an off-board charger, check the charge status LED. If it is not lit or blinking, then you likely have a faulty charger and it will need to be
replaced. However, if the light is on and is blinking then the batteries aren’t fully charged and the charge cycle needs to be completed.
Also, check for the fault LED to be lit and if so, review the manual that comes with your off-board charger for fault details.
If the batteries are wet, lead acid batteries, check the water levels in the battery cells. If they require watering, refer to the Battery Watering segment of this manual.
If the batteries don’t require watering and are over 18 months old, you’ve likely started to reach a point in the battery’s life where their capacity is starting to decline. If you are able to meet your run time requirements, then you still have some useful life left. However, if
the capacity has reduced the run time to below your requirements, then it is time to replace the batteries. See Changing Batteries
segment of this manual for further instructions on how to replace your batteries.
If none of these factors are present and you are still not getting expected run times, contact your distributor or Pacific Floorcare for technical support.

3. MACHINE WON’T DISPENSE WATER
1
First, when this issue occurs, check the solution tank sight gage for water level. If empty, fill the tank with cleaning solution.
2 Check the solution flow adjustment knob and ensure that the knob is adjusted to the solution flow level you desire.
3
If there is solution in the sight gage and the solution flow adjustment knob is properly positioned, then the filter is likely clogged with debris and needs to be cleaned. Start by draining the solution tank. Unscrew the inline filter, located on the underside of the unit between the wheels and the casters, and clean out the debris. Once clean, re-attach the filter and tighten it until snug. Ensure the screen
filter element is aligned properly with the body of the filter during reassembly. Fill the solution tank and check for solution flow. If
solution is flowing, you’ve identified the issue and you can return to cleaning.
4
Check the wire connections to the valve.
If none of the actions listed above fix the solution flow, contact your distributor or Pacific Floorcare for technical support.

TROUBLESHOOTING
OPERATOR TOP FIVE TROUBLESHOOTING LIST
4. RECOVERY TANK NOT DRAINING
If your recovery tank is not draining, there is a clog somewhere in the draining system. The two main areas of potential clogging are at the tank drain or at the restriction collar on the drain hose.
1
2
Start by checking the restriction collar being sure to keep the hose well above the top of the recovery tank so that the water doesn’t splash out once the debris is cleared. If the clog is located here, clear the clog with your hand or a tool and then drain as normal.
If the clog is not located at the restriction collar, then it is likely in the recovery tank at the drain opening. In this case, we suggest that the operator put rubber gloves on prior to submerging their hand to check for the clog. Once the clog is found, clear the drain and then
empty as normal.
In the unlikely event that the clog is in another part of the drain hose, we encourage utilizing a water hose to back flush the clog from the
recovery hose. Of course, a long thin tool of some kind can be used as well, but be extremely careful not to puncture the hose wall.
If a clog isn’t found in the system, contact your distributor or Pacific Floorcare for technical support.

5. SQUEEGEE ISN’T PICKING UP WATER IN TIGHT TURNS
The squeegee is designed to swing fully from left to right to the point where the squeegee system almost touches the casters. Should it be stopping well short of this, then it is likely that the recovery hose is not routed properly and has become an obstruction.
1
To fix this, route the recovery hose to have the loop hose trap between the squeegee assembly neck and left easy-grip knob.
If this isn’t the issue, contact your distributor or Pacific Floorcare for technical support.
