The Fuel Gauge
The Battery Fuel Gauge provides battery status information using five red LEDs.
Press the Fuel Gauge button to display the lights. The fuel gauge lights will remain lit for
approximately five seconds.
The numbers represent each LED and the grid is how they're laid out:

Battery Status Indicator Lights
On the control panel there are 2 sets of lights: on the top side of the battery lights indicate
the charge level in the battery attached to the left side of the ventilator, on the bottom side
of the battery lights indicate the charge level in the battery attached to the right side of the
ventilator.

If the battery is charging, the green indicator lights will horizontally scroll from left-to- right,
turning solid green when the battery is fully charged.
If the ventilator is running on battery power, the estimated remaining battery time is
shown.
If all the lights flash red, this indicates that the battery has failed and the battery must be
replaced.
Battery Pack Protection
• To protect itself from damage and extend its life, the battery pack's intelligent circuit
monitors current draw and temperature. In extreme situations, the battery pack will
turn OFF the ventilator if the current draw becomes too high. All the fuel gauge lights
will flash.
• Under extreme circumstances, the internal temperature of the battery could become
too high. If this happens, the fuel gauge lights will flash in an alternating pattern and
the tool will not run.
• While a battery undergoes a charge cycle, its temperature rises. To prevent grid
corrosion and eventual battery failure, allow the battery to cool down in between
charging and discharging.
