Availability of IRIS battery metric reporting is not guaranteed with third party supplied batteries.

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.

NOTE: The amount and type of soilage play an important role in determining the type of brush or pad to use. Contact a Tennant representative for specific recommendations.

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 re-coating.

Stripping pad (Brown) - Used for stripping of floor finish to prepare the floor for recoating.

Heavy duty stripping pad (Black) - Used for aggressive stripping of heavy finishes/sealers, or very heavy duty scrubbing.

Surface preparation pad (Maroon) - Used for very aggressive chemical free removal of floor finish to prepare the floor for re-coating.

Turf scrubbing pad (Green) - Used to scrub uneven floor surfaces with crevices, cracks and deep grout lines.

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 standard wet lead-acid batteries more than once a day and only after running the machine for a minimum of 15 minutes. TPPL batteries can be opportunity charged during the day to extend run time.
• 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 temperatures between 32°F (0°C) and 80°F (27°C).
• Allow the charger to complete charging the batteries before re-using the machine.
• Maintain the proper electrolyte levels of flooded (wet lead-acid) batteries by checking levels weekly.

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

Maintenance-free (Sealed AGM/TPPL) 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.

NOTE: If machine is equipped with the automatic or manual battery watering system, proceed to the BATTERY WATERING SYSYEM instructions (page 46).

The electrolyte level should be slightly above the battery plates as shown before charging (Figure 104). 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 0.12 in (3 mm) below the sight tubes.

NOTE: Make sure the battery caps are in place while charging. There may be a sulfur smell after charging batteries. This is normal.

Checking connections / cleaning (all battery types)

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 105). 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 106).

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.

To turn on the battery power (when the batteries are shutdown), press and hold the power button on each battery for 5 seconds. The battery discharge green indicators will illuminate when turned on.
