GETTING STARTED

1. Connecting the charger: Connect the charger to the
supply mains. A flashlight on the top will automatically
turn on to assist you in dark situations. 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
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 charger to the
supply mains. Connect the red clamp to the battery’s
positive (+) pole, and then the black clamp to the
battery’s negative (-) pole.

2. When all 4 charge level indicators are constantly lit, the
battery is fully charged and has entered maintenance
mode. The battery will be kept fully charged as long as
charger is plugged in to the mains.

battery, and the charge level indicators will start rolling
from “battery empty” to “battery full”. After a little
while, the LEDs will have a steady light indicating the

finished all 4 LEDs will be lit.
