CHARGING BATTERIES
The charging instructions in this manual are intended
for the battery charger supplied with your machine. The
use of other battery chargers that are not supplied and
approved by Tennant are prohibited.
If your machine is equipped with an off-board battery
charger refer to the charger owners manual for
operating instructions. Contact distributor or Tennant
for battery charger recommendations.
FOR SAFETY: The use of incompatible battery
chargers may damage battery packs and
potentially cause a fire hazard.
IMPORTANT NOTICE:
The battery charger is set to
charge the battery type supplied with your machine. If
you choose to change to a different battery type or
capacity (i.e. flooded (wet) lead-acid,
maintenance-free, sealed, AGM batteries, etc.), the
charger's charging profile setting must be changed and
the machine must be reprogrammed to prevent battery
damage. See BATTERY CHARGER SETTINGS.

owners manual for operating instructions.
FOR SAFETY: Do not disconnect the off-board
