GETTING STARTED

1. Connecting the charger: The battery terminal not
connected to the chassis has to be connected first. The
other connection is to be made to the chassis, remote
from the battery and fuel line. The battery charger is
then to be connected to the supply mains. The red
clamp should connect to the positive (+) pole of the
battery and the black clamp to the negative (-) pole.
For stand-alone batteries: Connect the red clamp to the
battery’s positive (+) pole, and then the black clamp to
the battery’s negative (-) pole. Then connect the
battery charger to the supply mains.

2. A constant green light means the battery is fully
charged.

3. After charging is complete, the charger will switch to a
maintenance mode to keep the battery fully charged as
long as charger is plugged in to the mains.
