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.
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 traction drive 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 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 nish your scrubbing application and recharge the unit. If you do choose to continue
scrubbing, when last LED begins to ash, the unit will shut down the brush motor but leave the vacuum
operational to perform nal 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.

Push or drive it into position so that the unit’s scrub head is centered over the pad driver or brush.
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 or
brush 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.
The operation is completed by quickly pulsing the S-20 activation trigger. This will “click on” the pad driver or brush. If the pad driver or
brush does 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 oor.

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, Pacic Floorcare’s goal was to provide an ergonomic, easy to use system. Due to this focus, the S-20’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.

SETTING DESIRED SOLUTION FLOW RATE
The next step is to set the unit to the desired solution ow. This control feature is located at the lower rear
of the machine and can be adjusted from low to high ow spanning a range of 0 to 0.5 gallons (1.9 L) per
minute.

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-20’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 S-20 scrub deck is lowered using the foot pedal at the rear of the unit.

pedal
Locking in high down pressure
setting by lifting foot lever
Self-adjusting head shroud with
bristle skirt
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-20 has two down pressure settings. The disk unit has settings of 60 and 90 lb (27 and 40 kg) and the orbital unit has 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
nish 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.
The disk scrub head is equipped with a self-adjusting shroud with bristle skirt that virtually eliminates overspray and increases ease of use.

To begin scrubbing, engage the handle trigger. The trigger activates solution ow, 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 S-20 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 ngers 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 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.

restriction collar
Raising recovery tank lid to fully
open position
Vacuum mesh lter screen and ball
oat system
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.
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.
