Use the Fuel Gauge to deter
mine the battery pack's re-
maining run time. Press the
Fuel Gauge button to dis-
play the lights. The Fuel
Gauge will light up for 2-3
seconds. When less than
10% of charge is left, 1 light
on the fuel gauge will flash
slowly.
NOTE: If the Fuel Gauge doesn't appear to be
working, place the battery pack on the charger and
charge as needed.
Compared to NiCd battery pack types, MILWAUKEE
Li-Ion battery packs deliver fade-free power for their
entire run time. The tool will not experience a slow,
gradual loss of power as you work. To signal the
end of discharge, 1 light on the fuel gauge will flash
quickly for 2-3 seconds and the tool will not run.
Charge the battery pack.
NOTE: Immediately after using the battery pack,
the Fuel Gauge may display a lower charge than it
will if checked a few minutes later. The battery cells
"recover" some of their charge after resting.
18 DC
To protect itself from damage and extend its life, the
battery pack's intelligent circuit monitors current draw
and temperature. In extremely high torque, binding,
stalling, and short circuit situations, the battery pack
will turn OFF the tool if the current draw becomes
too high. All the fuel gauge lights will flash. Release
18 DC
the trigger and restart.
Under extreme circumstances, the internal tem-
perature 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. Allow the
battery to cool down.
