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

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.

On lead acid battery-equipped units, when the discharge level reaches the rst red LED, it is a good time
to nish your scrubbing application and recharge the unit. If you do choose to continue scrubbing, when
the last red LED begins to ash, the unit will shut down the brush motor but leave the vacuum and
traction drive operational to perform nal 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 battery power level gage also displays fault codes. The LEDs will ash specic fault codes if

a fault is detected. See Troubleshooting section for LED fault codes.

the upper hook, all without having to unravel the entire cord.

After charging is complete, wrap the cord of your on-board charger securely to ensure the cord is not damaged.

MACHINE PREPARATION

SETTING THE DIP SWITCHES ON YOUR ON-BOARD CHARGER FOR YOUR BATTERY TYPE

Both the on-board and off-board chargers are able to charge wet, lead acid or maintenance-free AGM batteries. As
your unit leaves Pacic Floorcare’s factory, the charger is set up to match the type of battery chosen in the original
machine order. Should you choose to change from the original battery type, the charger can be changed by re-setting
the dip switches.

NOTE: The on-board charger has been programmed to work with the batteries that Pacic Floorcare provides. Using
other battery types not specied for the S-Series mid-size scrubber by Pacic Floorcare may impair performance of the

unit and will affect the life of the batteries.

MACHINE OPERATION

OPERATIONAL CONTROLS

Once the machine is powered on and the solution ow 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-Series mid-size scrubber’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.

Lowering scrub head using foot

pedal

Lower down pressure setting

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
the scrub deck into the operating position.

The S-Series mid-size scrubbers have three down pressure settings.

• The 24-inch (610 mm) disk unit has settings of 50, 100 & 140 lb (23, 45 & 64 kg)

• The 28-inch (711 mm) & 32-inch (813 mm) disk scrubbers have settings of 70, 110 & 150 lb (32, 50 & 68 kg)

• The 28-inch (711 mm) orbital scrubber has settings of 70, 110 & 160 lb (32, 50 & 73 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 nish removal, you can engage

higher down pressure settings. To engage the medium down pressure setting, lift the foot pedal lever so that the hook is secured in the
cutout in the foot lever. To engage high down pressure, lift the foot lever to the upper notch position so that the bottom of the lever is
locked on the hook of the bracket. To disengage medium or high down pressure, simply lift and shift the lever to the right and lower into
normal operating position.

MAINTENANCE

END OF SHIFT

Once you’ve completed your daily scrubbing, project work or nish 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.

Recovery tank drain hose

Drain hose has a press-t cap and

restriction collar

Vacuum mesh lter screen and ball

oat system indicated above

Empty debris tray and clean out

The drain hose has a press-t cap that is removed for the draining process.

The hose is also equipped with a restriction collar that can be bent or squeezed to reduce splashing and spraying during the operation.

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. This

is a great time to inspect and clean the vacuum mesh lter screen and ball oat system. This can be removed for cleaning by
unscrewing the lter screen and rinsing it with a hose or faucet.

Empty and clean the debris tray after every use. Operating the machine without the debris tray can lead to a clogged outlet hose or
facility drain

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 oor so proper maintenance is important

for making it perform at its peak.

To ip or replace squeegee blades,

release over-center latch

Remove the blade and either ip to

fresh edge or replace

Slide the squeegee retainer off the

hook on the other side

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.

Inspect the front and rear squeegee blades. If the blade edges are not clearly dened or worn halfway through the thickness of the
blade, then it is time for replacement or to be ipped to another edge. The S-Series mid-size scrubber’s squeegee blades have four

usable edges.

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.

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 nish 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-Series mid-size scrubber, you can select from two types of batteries: wet, lead acid or sealed, maintenance-free AGM.

WET, LEAD ACID BATTERY MAINTENANCE

Wet batteries, by denition, 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 ll the water level to the cap. This causes the battery to overow 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 ll wells. Add distilled water until the electrolyte level is approximately 1/8 in (3.2 mm) below the bottom of the ll well. Clean and

replace the vent caps.

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 ll 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 identied 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 lled to the proper level.

HydroLink® battery watering system

WARNING:

Fire or explosion hazard. Batteries emit Hydrogen gas. Keep sparks and open ame away. Keep battery compartment

open when charging.

For safety, when cleaning batteries, wear protective gloves and eye protection. Avoid contact with battery acid.

CAUTION:

END OF SHIFT

BATTERYSHIELDTM AUTOMATIC WET BATTERY PROTECTION SYSTEM

If your scrubber is equipped with BatteryShield technology, your scrubber will provide you “real time” notication 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 LED on back panel

BatteryShield optical sensor on

Trojan battery

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 lled with distilled water using the HydroLink single-point battery watering
system. After lling 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. Note: Failure to clean your light pipe will limit

BatteryShields’ ability to read the low water condition and may reduce the life of your batteries.

For safety, when cleaning batteries, wear protective gloves and eye protection. Avoid contact with battery acid.

CAUTION:

HydroLink battery cap light pipe

circled above

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-Series mid-size scrubber performing at peak levels. Remove the

pad drivers or brushes to check for wear.

Depress position “A” for 1 second

then depress position “B”

To remove the pad drivers or brushes 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”.

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.

PERIODIC MAINTENANCE

CHANGING BATTERIES

To change the batteries in your S-Series mid-size scrubber, move the machine to an area with a level surface, turn off the power switch and

remove the key. If using an off-board charger, make sure that it is located near your machine and that your location is close to an electrical
outlet for charging after installation.

WARNING:

To access the battery compartment, tilt the recovery tank to the fully open position. Using proper open-ended wrench, disconnect the

main ground cable rst and secure terminal away from the batteries. Disconnect main positive cable and secure terminal away from

the batteries. Loosen all terminals on the jumper cables and remove. Attach a suitable battery lifting device and lift the batteries from
the machine.

Reverse the order of the instructions above to install new batteries by orienting and connecting the batteries as shown in the Battery
connection diagram. After installation is complete, be sure to charge your batteries before operating the machine.

NOTE: If changing battery types from wet, lead acid to AGM or vice versa, see Machine Preparation section for instructions on setting
the dip switches on your machines battery charger before beginning the charge cycle to avoid damaging or undercharging your
batteries.

Batteries are a potential environmental hazard. Consult a battery supplier for safe disposal methods.

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 xed with
some easy troubleshooting by the operator. Because there are so many scenarios, we’ve generated the top ve 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 oat 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 identied and corrected the issue.

Lower elbow of recovery hose and

squeegee assembly neck

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.

Then, check the upper elbow and the recovery tank orice. 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 orice to ensure all the debris is removed.

If a clog isn’t identied in the recovery hose, check the squeegee neck by loosening the easy grip knobs, removing the squeegee
assembly and ipping it over. Clear the debris, and again, if a hose is available, rinse the squeegee opening.

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, ip to a new blade edge or order a replacement blade.

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.

Off-board charger LEDs

(charger appearance may vary)

On-board charger LEDs

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.

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 Pacic Floorcare for

technical support.

If there is solution in the sight gage and the solution ow adjustment knob is properly positioned, then the lter is likely clogged with
debris and needs to be cleaned. Start by draining the solution tank. Unscrew the inline lter, located on the underside of the unit be­tween the wheels and the casters, and clean out the debris. Once clean, re-attach the lter and tighten it until snug. Ensure the screen
lter element is aligned properly with the body of the lter during reassembly. Fill the solution tank and check for solution ow. If
solution is owing, you’ve identied the issue and you can return to cleaning.

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.

Check for clog in the restriction collar

Check for clog in the recovery tank at

the drain opening

Drain opening

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 ush 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 Pacic 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.
