Battery Charging Status Indicators
The battery charging status LED indicators are located
next to the charger AC input receptacle on the rear
bumper of the machine. This LED indicator set is plugged
directly into a connector on the back of the battery
charger and indicates current charging status.
When first plugged in, the charger runs through a self-
diagnostic test, lighting the LEDs in sequence, then charg-
ing will begin. The following descriptions indicate charg-
ing status after diagnostic test is complete.
Wet/VRLA Battery - Charging Profile Switch
The battery charger is equipped with a manually select-
able charge profile switch, located on the rear panel. This
switch must be set properly to select the charging profile
required for either WET gassing lead acid batteries or
VRLA - Valve Regulated Lead Acid, gelled/agm type lead
acid batteries.
The machine is equipped from the factory with VRLA -
valve regulated lead acid batteries, and the switch is set
from the factory to VRLA. If the factory batteries are
replaced with wet gassing batteries, set this switch to
WET.

AN IMPROPER PROFILE SETTING MAY DAMAGE THE BATTER-
