Charging Batteries - Tennant 1610 Operator's Manual

CHARGING BATTERIES

ATTENTION: To prolong the life of the batteries
and to provide optimum machine performance,
ONLY recharge the batteries after a total of 30
minutes of use or more. Do not leave batteries
discharged for lengthy periods.
BATTERY METER: When the machine's battery
meter begins to flash, stop scrubbing and recharge
batteries. If two lights begin to flash alternately, the
cleaning function will automatically shut off and the
scrub head will rise to the transport position. This will
protect the batteries from total discharge.
Only use a battery charger with the following
specifications to prevent battery damage.

for charging.
WARNING: Fire Or Explosion Hazard.
Batteries Emit Hydrogen Gas. Keep Sparks And
Open Flame Away. Keep Battery Compartment
Open When Charging.
2. Park the machine on a level surface, set parking
brake and turn the key off.
3. Before charging the batteries, periodically check the
electrolyte level in each battery cell (Figure 24).

cord from the machine's receptacle when the
charger is operating. Arcing may result. If the
charger must be interrupted during charging,
disconnect the AC power supply cord first.
