  • Page 2: Safety Precautions

    SAFETY PRECAUTIONS This machine is intended for commercial use. Only use recommended pads or brushes and commercially approved floor cleaning chemical intended for machine application. The following symbols will be used to warn you of hazards or unsafe practices which could result in personal injury or death: CAUTION: INDICATES A POTENTIALLY HAZARDOUS SITUATION WHICH, IF NOT AVOIDED, MAY RESULT IN MINOR OR MODERATE INJURY.
  • Page 3 SAFETY PRECAUTIONS NOTE: Do not allow the brush/pad to operate while the machine is stationary to avoid damage to the floor. CAUTION: Do not bump into shelves or scaffoldings, especially where there is a risk of falling objects. CAUTION: Before leaving or servicing a machine, stop it on a level surface. NOTE: Before leaving or servicing a machine, turn off the unit and remove the key.

  • Page 4: Unpacking The Machine

    NOTE: The on-board charger has been programmed to work with the batteries that Pacific Floorcare provides. Using other battery types not specified for the S-Series mid-size scrubber by Pacific Floorcare may impair performance of the unit and will affect the life of the batteries.

  • Page 5: Battery Power Level Indicator

    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.

  • Page 6: Machine Preparation

    MACHINE PREPARATION USING YOUR ON-BOARD CHARGER CHARGING THE BATTERIES WITH AN ON-BOARD CHARGER Before using your S-Series mid-size scrubber for the first time, fully charge your batteries. These units can be equipped with an on-board charger. The on-board charger is equipped with a 9 foot long cord that can be plugged directly into a 120V outlet. Do not use an extension cord. This will void the warranty on the charger.

  • Page 7: 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 Pacific 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.
  • Page 8 MACHINE PREPARATION USING YOUR OFF-BOARD CHARGER CHARGING THE BATTERIES WITH AN OFF-BOARD CHARGER Before using your S-Series mid-size scrubber for the first time, fully charge your batteries. These units can be equipped with an off-board charger. The off-board charger has both a standard 120V power cord and a cord with an “Anderson connector”. There is also an Anderson connector on-board the S-Series mid-size scrubber located on the lower control panel at the rear of the machine.
  • Page 9 SETTING THE DIP SWITCHES ON YOUR OFF-BOARD CHARGER FOR YOUR BATTERY TYPE The off-board charger is able to charge wet, lead acid or maintenance-free AGM batteries. As your unit leaves Pacific 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 to the other, the charger can be changed by re-setting the dip switch.

  • Page 10: Solution Tank

    MACHINE PREPARATION SOLUTION TANK To prepare the machine for cleaning, the unit must be filled with cleaning solution. Water and cleaning agent can be added to the S-Series mid-size scrubber’s rear hose fill port located to the left of the control panel. There is also a front fill port that is able to accept hose or bucket filling.
  • Page 11 MACHINE PREPARATION SOLUTION TANK - AUTO-OFF SOLUTION FILL SYSTEM OPTION If your machine is equipped with the auto-off solution fill system option, connect the male end of the quick-connector to your 1/2-inch inner diameter fill hose. Once your fill hose is set up, leave the faucet for that hose open - the connector will act as a stop. When it is time to fill your machine, click the hose onto the female quick-connector at the back of the machine and the unit will begin to fill with water.

Due to this focus, the S-Series mid-size scrubber’s key operational controls are all within reach so that the operator doesn’t have to remove their hands to perform...
  • Page 18 MACHINE OPERATION ON-BOARD CHEMICAL INJECTION SYSTEM If your S-Series mid-size scrubber is equipped with the on-board chemical injection system, the following instructions will walk you through the easy process of setting up and operating this system. Lift the recovery water tank, opening it as far as it will go using the side handle. Place your 1-gallon chemical container in the holder inside the machine’s battery compartment and remove the cap.
  • Page 19 MACHINE OPERATION ON-BOARD CHEMICAL INJECTION SYSTEM Once the chemical mix ratio is selected, set your desired solution flow rate to low, medium or high based on your cleaning needs and the chemical injection system will automatically mix your chemical for you. A solid green LED indicates the system is powered and working properly.
  • Page 20 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-Series mid-size scrubber’s “1, 2, 3-Step”...
  • Page 21 MACHINE OPERATION OPERATIONAL CONTROLS LOWERING THE SCRUB DECK The scrub deck is lowered using the foot pedal at the rear of the unit. The disk scrub head is equipped with a self-adjusting shroud with bristle skirt that virtually eliminates overspray and increases ease of use. LOWERING THE SQUEEGEE To lower the squeegee, lift the squeegee lever and shift it left to clear the notch.
  • Page 22 MACHINE OPERATION OPERATIONAL CONTROLS ACTIVATING THE SCRUBBER To begin scrubbing, engage the handle trigger. The trigger activates solution flow, the brush motor and traction drive.
