Fuel Gauge Battery Packs (Fig. B)
Some D WALT battery packs include a fuel gauge which consists
e
of three green LED lights that indicate the level of charge
remaining in the battery pack.
To actuate the fuel gauge, press and hold the fuel gauge
button 14 . A combination of the three green LED lights will
illuminate designating the level of charge left. When the level of
charge in the battery is below the usable limit, the fuel gauge
will not illuminate and the battery will need to be recharged.
nOTE: The fuel gauge is only an indication of the 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.
Electronic Overload Protection
If the drill bit becomes jammed, the power to the drill spindle
will be interrupted by the activation of the electronic overload
protection. To reactivate the power to the drive spindle, the
tool's trigger should be released and then depressed. Due to the
resulting forces, always hold the tool with both hands and take
a firm stance.
Active Vibration Control (Fig. A)
For best vibration control, hold the tool with one hand on the
main handle 6 and the other hand on the side handle
just enough pressure so the Active Vibration Control
rear handle are halfway depressed. The hammer only needs
enough pressure to engage the internal active vibration control.
Applying too much pressure will not make the tool drill faster
and active vibration control will not engage.
