BATTERIES

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

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

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

S Do not charge the batteries more than once a dayand only after running the machine for a minimum of

15 minutes.

S Do not leave the batteries partially discharged forlong period of time.

S Only charge the batteries in a well-ventilated area toprevent gas build up.

S Allow the charger to complete charging the batteriesbefore re-using the machine.

S Maintain the proper electrolyte levels of flooded (wet)

batteries by checking battery cell levels weekly.

FOR SAFETY: When servicing machine, batteryinstallation must be done by trained personnel.

FOR SAFETY: When servicing machine, keep allmetal objects off batteries. Avoid contact withbattery acid.

MAINTENANCE-FREE BATTERIES

Maintenance-free (Sealed AGM) batteries do notrequire watering. Cleaning and other routinemaintenance is still required.
