IRIS battery charging metrics notification

Machines equipped with capability to report battery charging data via IRIS are supplied with a charger and set of batteries from the factory. When a battery reaches its end of life and must be replaced, Tennant highly recommends that the same battery type be used to continue to maximize the machines performance. In the event a battery with a different amp hour (AH), type (Flooded, AGM, Gel, TPPL), or manufacturer is selected for replacement please contact Tennant technical service department for assistance in determining the feasibility of the replacement batteries and if so, selecting the correct charging profile. 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.

Tufted pad driver - Standard pad driver has short bristles, or “tufts,” on the back to hold the pad in place.

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 re-coating.

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.

Melamine scrubbing pad (Orbital scrub head model) - Made of an open-cell polymeric foam that removes black marks from floors and restores tile.

Machine setup

Installing squeegee assembly

Scrub heads and squeegee assemblies are identified by size (Figure 4). Refer to table below for appropriate squeegee assembly size for specific scrub head size.‌‌​⁠‍‍⁠‍‌‌​⁠‌‌⁠‍‍‌‍​​​​​​‌​‌​​​‌​‍⁠⁠​⁠⁠‌⁠⁠​‌‌​‌⁠​​​​​⁠‌‍​⁠‌⁠

1. Lift the squeegee mount bracket to the raised position. Place foot under pedal to lift (Figure 5).

2. Attach the squeegee assembly to the squeegee mount bracket (Figure 6). Make sure the black disks are positioned below the squeegee mount bracket as shown. Tighten the star knobs by hand only.

NOTE: Do not over-tighten the star knobs. The squeegee assembly should easily detach from bracket if it hooks a fixed object.

3. Connect the vacuum hose to the squeegee assembly (Figure 7).

4. Check squeegee blade for proper roll-out. Lower squeegee to floor and propel machine forward for a short distance. The rear blade should roll-out evenly across the full length of the squeegee at a 45° deflection (Figure 8).

NOTE: The two squeegee casters are factory set and should not require any adjustment.

5. If the squeegee blade does not deflect evenly across the full length of the squeegee, the blade pitch may be out of adjustment (Figure 9).

NOTE: The blade pitch adjustment is factory set and should not require further adjustment. However, if blade tips are higher or lower than center of squeegee, blade pitch adjustment is required.‌‌​⁠‍‍⁠‍‌‌​⁠‌‌⁠‍‍‌‍​​​​​​‌​‍​​​‌​‍⁠⁠‌‌​​​​​​​⁠​⁠‍‌‍​‍​​⁠​⁠⁠‍

6. To readjust blade pitch, loosen locking nut on adjustment shaft and rotate shaft counterclockwise to raise squeegee tips or clockwise to lower squeegee tips (Figure 10). 7mm and 17mm wrench required.

Installing and removing disk brushes/pads (disk scrub head model)

1. Raise scrub head off floor and remove key.

2. Attach the pad to the pad driver before installing the driver. Secure pad with center-lock (Figure 11).

3. Set the yellow spring clips to the open position to make brush installation easier. Press spring clips together then downward to set (Figure 12).

4. Align the pad driver or brush under the motor hub and push it upward to engage hub (Figure 13).

Replace pads or brushes when they no longer clean effectively or when the bristles on the brush disk are worn to the yellow indicator (Figure 13).‌‌​⁠‍‍⁠‍‌‌​⁠‌‌⁠‍‍‌‍​​​​​​‌​⁠​​​‌​‍⁠⁠⁠​⁠‌‍‍‍⁠​‌​​⁠‍​⁠​​⁠‌‍⁠‍‍

5. To remove the pad drivers/brushes, raise the scrub head and press down on the yellow pad release plunger (Figure 14). Pad will drop to floor.

NOTE: If the pad driver/brush does not easily drop to floor, try aligning the spring clip with the plunger before pressing the plunger.

Installing orbital pads (orbital scrub head model)

Batteries

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

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

Flooded (wet) and maintenance-free sealed lead-acid batteries

• Do not charge the 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.
• 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 battery cell 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 SYSTEM instructions (page 56).

Corrected an obvious misprint: "BATTERY WATERING SYSYEM" printed with a typo (now "SYSTEM", as in the Battery watering system headings on pages 56 and 57).

The electrolyte level should be slightly above the battery plates as shown before charging (Figure 118). 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

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 119). Do not remove battery caps when cleaning batteries.

Lithium-ion battery pack

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:‌‌​⁠‍‍⁠‍‌‌​⁠‌‌⁠‍‍‌‍​​​​​​⁠‌‌​​​‌​‍⁠⁠‌⁠⁠‍‍‍‌‌‌⁠‌⁠​⁠‌⁠⁠​⁠‌​⁠‍‌

• 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.
• It is recommended to only recharge battery pack when the discharge level is fully depleted (i.e. when discharge indicator reaches red light). If the red light begins to flash, the scrub function will automatically be disabled. This allows the user to use the remaining power to propel the machine back to charging station. Do not store the machine for a long period at this depleted level, the battery pack 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.
• Allow charge cycle to completely charge battery pack.
• Avoid frequent complete charge cycles if battery pack was not fully depleted.
• Opportunity charging (i.e. partial charge cycle of a half hour or more) is only recommended if discharge level is below 80% (i.e. when discharge indicator is at or beyond second green light).
• Do not operate machine in temperatures above 110°F / 43°C or below -4°F / -20°C. Machine may shutdown if exceed these temperatures.
• When removing or replacing the lithium-ion battery pack, a specific lifting kit is recommended. It's important to use non-conductive lifting straps positioned at all four lift points with straps angled at 45° or greater when hoisting battery pack.
• Contact Tennant Service for lithium-ion battery service and replacement.

Pushing and transporting machine

Pushing machine

If the machine becomes disabled, it can be pushed as describe below.

Only push the machine for a very short distance and do not exceed 2 mph (3.2 km/h). It is not intended to be pushed for a long distance or at a high speed.

For models equipped with an electronic parking brake system, the brake must be disengaged before pushing machine. To disengage brake, position the brake lever on the transaxle to the down position (Figure 146).

Corrected an obvious misprint: "3.2 kp/h (2 mph)" printed with a typo (now "2 mph (3.2 km/h)"; kp/h is km/h, and 3.2 km/h is 2 mph).

Immediately after pushing the machine, re-engage the brake lever to prevent a roll hazard.‌‌​⁠‍‍⁠‍‌‌​⁠‌‌⁠‍‍‌‍​​​​​​⁠⁠‌​​​‌​‍⁠⁠‍‍‌⁠⁠‌​⁠⁠⁠‌‌‌⁠⁠‌​⁠‍‌‌‌‌‌

NOTE: When brake lever is disengaged, the propel will be disabled and a fault will be detected until lever is re-engaged.
