indicate the level of charge remaining in the battery
pack.
To actuate the fuel gauge, press and hold the fuel
gauge button (k). A combination of the three green
LED lights will illuminate designating the level of

charge left on the battery pack. It does not indicate
tool functionality and is subject to variation based
on product components, temperature and end-user
application.
