Tennant Floor Scrubber T300

FOR SAFETY: Before servicing machine, stop on level surface, turn off machine and remove key.

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

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 80F/27C and above 32F/0C. Battery pack may shut down and not take a charge in elevated or freezing temperatures.

FOR SAFETY: Before leaving or servicing machine, stop on level surface, turn off machine, remove key and set parking brake if equipped.

The water conditioning cartridge is required to be replaced when it reaches its maximum water usage or expiration time of when the cartridge was activated, which ever comes first. The control panel will signal a code when it’s time to replace cartridge.

Depending on machine usage, on average, a new cartridge can last anywhere from 12 months for heavy machine usage to 24 months for light machine usage.

ATTENTION: During first time use and after replacing the water conditioning cartridge, the ec-H2O system will automatically override the solution flow setting to the maximum flow rate for up to 60 minutes to properly prime the cartridge. During this time, the machine can be operated as normal.

Park the machine on a level surface, remove the key and set parking brake, if equipped.

Lift the recovery tank to access the ec-H2O water conditioning cartridge. Drain recovery tank before lifting tank.

Disconnect the two hose connectors from the top of the cartridge by pressing the gray collars inward and pulling the connectors outward. Lift cartridge to remove.

Fill in the installation date on the new cartridge label.

Install the new cartridge and reconnect the two hoses. Make sure the hose connectors are fully inserted into the cartridge.
