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.

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.
