OPERATING INSTRUCTIONS
5. LED Work Light
The LED work light (G), located on the base of
the hammer drill, will illuminate when the variable-
speed trigger switch (E) is depressed. This provides
additional light on the surface of the workpiece for
operation in lower-light areas.
The LED work light will turn off after the variable-
speed trigger switch is released.
a. The LED work light will blink rapidly if the tool
has stopped working in order to protect internal
circuits; please wait for the tool to cool down, at
which point it can be started again.
b. The LED work light will blink slowly to indicate
that the battery charge is very low.
6. Keyless Chuck
The hammer drill has a keyless chuck (A) to tighten
or release drill bits in the chuck jaws. The arrows on
the chuck indicate the direction in which to rotate
the chuck body in order to GRIP (tighten) or OPEN
(release) the chuck jaws on the drill bit.
7. Mode Selector
The mode selector (D) allows the tool to be set for
various drilling and hammer drilling applications.
Rotate the selector up or down, depending on the
application.
Driving mode : For driving screws.
Drilling mode : For drilling action in woods,
metals, plastics or other materials.
Hammer mode : For drilling with hammer action in
