HOW THE MACHINE WORKS

Conventional scrubbing:
When using the conventional scrubbing mode, water and detergent mixture from the solution tank flows to the floor and the rotating brush(es)/pad(s) scrub the floor clean. As the machine moves forward, the squeegee with vacuum suction picks up the dirty solution from the floor into the recovery tank.

ec-H2O NanoClean Technology (option):
When using the ec-H2O NanoClean technology, normal water passes through a module where it is electrically converted into a cleaning solution. The electrically converted water attacks the dirt, allowing the machine to easily scrub away the suspended soil. The converted water then returns to normal water in the recovery tank.

BRUSH AND PAD INFORMATION

For best cleaning results use the appropriate brush or pad for your cleaning application. Listed below are brushes and pads and the applications for which each is best suited.

Soft nylon bristle scrub brush (White) −
Recommended for cleaning coated floors without removing finish. Cleans without scuffing.

Polypropylene bristle scrub brush (Black) −
This general purpose polypropylene bristle scrub brush is used for scrubbing lightly compacted soilage. This brush works well for maintaining concrete, wood and grouted tile floors.

Super abrasive bristle scrub brush (Gray) −
Nylon fiber impregnated with abrasive grit to remove stains and soilage. Strong action on any surface. Performs well on buildup, grease, or tire marks.

Polishing pad (White) −
Used to maintain highly polished or burnished floors.

Buffing pad (Red) − Used for light duty scrubbing without removing floor finish.

Scrubbing pad (Blue) − Used for medium to heavy-duty scrubbing. Removes dirt, spills, and scuffs and leaves surface clean ready for recoating.

BATTERIES

Your machine is equipped with either flooded (wet) lead-acid, maintenance-free (Sealed AGM) batteries or lithium-ion battery supplied by Tennant.‌‌​⁠⁠‍‍‌⁠⁠‌​​​⁠‌‍‌‌‍​​​​​‍‌‌​​​‌​⁠​​​‌​​⁠⁠‌​⁠⁠‍‍‍​‌​⁠⁠‌⁠​‍⁠‍

FLOODED (WET) AND MAINTENANCE-FREE SEALED LEAD-ACID BATTERIES

The lifetime of the batteries depends on their proper maintenance. To get the most life from the batteries:

• Do not charge the batteries more than once a day and only after running the machine for a minimum of 15 minutes.
• Do not leave the batteries partially discharged for long period of time.
• Only charge the batteries in a well-ventilated area to prevent gas build up. Charge batteries in areas with ambient temperatures 80°F / 27°C or less.
• Allow the charger to complete charging the batteries before re-using the machine.
• Maintain the proper electrolyte levels of flooded (wet) batteries by checking levels weekly.

Your machine is equipped with either flooded (wet) lead-acid or maintenance-free batteries supplied by Tennant.

Maintenance-free (Sealed AGM) batteries do not require watering. Cleaning and other routine maintenance is still required.

The flooded (wet) lead-acid batteries require routine watering as described below. Check the battery electrolyte level weekly.

The electrolyte level should be slightly above the battery plates as shown before charging (Figure 103). Add distilled water if low. DO NOT OVERFILL. The electrolyte will expand and may overflow when charging. After charging, distilled water can be added up to about 3 mm (0.12 in) below the sight tubes.

CHECKING CONNECTIONS / CLEANING

After every 200 hours of use, check for loose battery connections and clean the surface of the batteries, including terminals and cable clamps to prevent battery corrosion. Use a scrub brush with a strong mixture of baking soda and water (Figure 104). Do not remove battery caps when cleaning batteries.

LITHIUM−ION BATTERY

The lithium−ion battery pack is a maintenance−free battery protected by a battery management system (BMS). To achieve the maximum battery life, carefully follow the instructions below:‌‌​⁠⁠‍‍‌⁠⁠‌​​​⁠‌‍‌‌‍​​​​​‍‌‍​​​‌​⁠​​⁠‌‌‍‍⁠⁠​⁠​‍​‍‌‍​‍‍​‍⁠‍‍​

• Lithium−Ion batteries must be charged prior to initial use.
• Carefully follow the Important Safety Instructions section in the manual when using the Lithium−ion Battery Model.
• Only use the lithium−ion battery charger supplied with machine.
• Charge battery pack in well−ventilated areas. For best charging performance, charge the battery pack in temperatures below 80°F/27°C and above 32°F/0°C. Battery pack may shut down and not take a charge in elevated or freezing temperatures.
• Do not store the machine for an extended period if battery is discharged to the last bar, the battery may further discharge to a level that is unrecoverable.
• When the machine shuts down due to a depleted battery pack, do not repeatedly cycle the key on and off. This may cause permanent battery pack damage. Recharge battery pack immediately to avoid damage.
• Opportunity charging (i.e. partial charge cycle of a half hour or more) is only recommended if discharge level is below 80%.
• Do not operate machine in temperatures above 104°F / 40°C or below −4°F / −20°C. Machine may shutdown if exceed these temperatures.
• Contact Tennant Service for lithium−ion battery service and replacement.

BATTERY POWER BUTTON / BATTERY DISCHARGE INDICATOR

Each Lithium−Ion battery contains a power button to turn on/off the battery power supply. The battery discharge indicator (BDI) displays the current state of the battery (Figure 105).

To display the battery charge status or fault state (while the batteries are active), press and hold the power button of any battery for one second. When the batteries are fully charged, all five green indicators are lit. As the battery discharges, the indicator levels decreases. If the indicators flash red the battery is getting very low. If the indicators display solid red along with green, the battery has a fault. Contact Tennant Service to fix the fault.

To turn off the battery power (while the batteries are active), press and hold the battery power button of any battery for 20 seconds. The battery discharge indicators will turn off. Turning off one battery will shut down power to all connected batteries. Batteries should be shut down before any service is completed on the battery modules.

SUPERVISOR CONTROLS

The supervisor controls feature allows a supervisor to program the machine’s scrubbing settings for operator use. The lockout functionality will prevent the operator from changing or saving the Zone Settings.‌‌​⁠⁠‍‍‌⁠⁠‌​​​⁠‌‍‌‌‍​​​​​⁠‍‌​​​‌​⁠​​​​​⁠⁠​​​‌⁠⁠‍‌⁠​⁠‌‌⁠⁠‌​⁠⁠

The supervisor controls feature will lower machine variability for consistent, repeatable cleaning results, machine quality assurance regardless of user experience, and reduce user training requirements.

T300 MODEL WITH PRO-MEMBRANE CONTROL PANEL

The machine has three supervisor control modes of operation to choose from:

Unlocked Mode 1: Operator has full control of all scrubbing parameters with the ability to save Zone Settings. The Unlocked Mode 1 is the factory default setting.

Lockout Mode 2: Zone Settings are configured and locked by supervisor. Operator has control to reconfigure the zone settings, but are not able to save them.

Lockout Mode 3: Zone Settings are configured and locked by supervisor. Operator is restricted to only use the Zone Settings configured by supervisor.

To enter the supervisor controls mode follow the instructions below:

1. Park the machine on a level surface and turn the key to off ( O ) position.
2. Press and hold the Down Pressure button while turning the key on. Release button when the far right battery discharge indicator LED turns on (Figure 133).

3. Select the preferred supervisor control mode by pressing the following Zone Setting buttons as described:
   Zone 1 button = Unlocked mode 1
   Zone 2 button = Lockout mode 2
   Zone 3 button = Lockout mode 3
   Hold down the Zone Setting button until it blinks three times to save the preferred supervisor control mode (Figure 134). In this example, Lockout mode 3 was selected.

4. If Lockout mode 2 or 3 was selected, press the Solution Flow button. This will allow you to configure the Zone Settings for the selected supervisor control mode (Figure 135).

5. Configure the following Zone Settings for zone 1. After the Zone Settings are configured, press and hold the zone button until it blinks three times to save Zone Setting. Repeat process for other zones.

   Zone Settings:

   • Down pressure rate
   • Solution flow rate
   • Quiet-Mode on or off (option)
   • ec-H2O mode on or off (option)
   • Maximum scrubbing speed (drive model)

To adjust the maximum scrub speed, press the circled button to cycle through the five speed selections as described below (Figure 136).

The speed selection is displayed by the battery discharge indicator LED’s. The red LED represents the lowest speed. The far right green LED represents the highest speed (Figure 136).

6. To exit the supervisor control mode, turn key off.

SUPERVISOR CONTROLS

T300 MODEL WITH PRO-PANEL CONTROLS

There are two types of user modes that will interface with the operator home screen:‌‌​⁠⁠‍‍‌⁠⁠‌​​​⁠‌‍‌‌‍​​​​​⁠‍‍​​​‌​⁠​​‍​⁠⁠‌⁠​​‌‌‍⁠​‍‌‍​​‍​‌​‍⁠

Operator Mode − Capable of machine operation with permissions and restrictions controlled by the supervisor.

Supervisor Mode − Capable of machine operation with full use of all controls, along with configuring permissions and restrictions for the operator mode.

A new machine from the factory will automatically start up in the supervisor mode with a preassigned default supervisor profile. The machine’s factory-assigned supervisor login number is “1234”. This login number is not required until it’s enabled. The default supervisor profile name and login number can be changed as described in this section. If the new assigned supervisor mode login number is forgotten, use the recovery login code 836626826.

To enter the supervisor controls follow the instructions below:

1. Park the machine on a level surface and turn the key to the on ( I ) position. The home screen will display at start up (Figure 137). This is the factory default screen at start up.
   NOTE: If a login screen appears at start up. Enter the factory-assigned supervisor login number or your saved personalized supervisor login number to access the operator home screen.
2. Press the settings button located on the home screen (Figure 137).

   

3. Press the Setup button to access the Setup screen (Figure 138). The Setup screen is only accessible with an assigned supervisor login number.

   

4. The Setup screen allows supervisor access to the following controls as described below.

   

Add/Edit Profiles − Provides the capability to add, edit, copy or delete user profiles.

Battery Type − Use this to select battery type installed in machine. This ensures the on-board battery charger charging profile is properly programmed to your battery type. See BATTERIES.

Enable Login − Activates a required login number at machine start up for all user profiles to operate machine.

Calibrate Touch Icon − Use this to calibrate the touch screen if the touch points become misaligned.

Factory Reset − Resets the supervisor login number back to the factory default number 1234, removes user profiles and resets any custom preset zone setting names back to the factory preset names.

To Add/Edit User Profiles

Before adding new user profiles, it is recommended to configure the four Zone Settings in advance (See CONTROL PANEL OPERATION).‌‌​⁠⁠‍‍‌⁠⁠‌​​​⁠‌‍‌‌‍​​​​​⁠‍⁠​​​‌​⁠​​​​‌​​‌​‍‍‍‌‌​‌⁠​​‌‍‍​​⁠‍
