NOTICE: Avoid running the hammer drill at low
speed for extended periods of time.
Running at low speed under constant use may
cause the drill to become overheated.
If this occurs, cool the drill by running it without
a load at high speed.
MODE SELECTION (FIG. 9)
Your tool has
three operating
modes: drilling
with hammering
action, drilling
only, and driving
screws. -To set
the operating
mode, rotate the
mode-selector
ring and torque
adjustment ring
to the desired settings.
To use the hammer-drilling mode:
1. Rotate the mode-selector ring until the ham-
mer symbol appears in line with the arrow.
2. Apply pressure to the bit during operation to
engage the hammering mechanism.
NOTE: The number selected on the torque-
adjustment ring has no effect on operation of
the drill in hammer mode.
To use the drilling only mode:
Rotate the mode-selector ring until the drill
symbol appears in line with the arrow.
NOTE: The number selected on the torque-
adjustment ring has no effect on the operation
of the drill in the drilling mode.
To use the driving screws mode:
1. Rotate the mode selector ring until the drive
symbol appears in line with the arrow.
2. Then rotate the torque-adjustment ring until
the desired clutch setting appears in line with
the arrow. The torque adjustment ring, when
properly adjusted, will slip at a preset torque to
prevent driving the screw too deeply into dif-
ferent materials and to prevent damage to the
screw or tool.

CLUTCH (FIG. 10)
Your tool fea-
tures 24 clutch
settings. Out-
put torque will
increase as the
torque-adjust-
ment ring is ro-
tated from 1 to
24. When using the hammer drill for different
driving applications, it is necessary to increase or
decrease the torque in order to help prevent the
possibility of damaging screw heads, threads,
workpiece, etc.
The proper setting depends on the job and the
type of bit, fastener, and material you will be
using. In general, use greater torque for larger
screws, but if the torque is too high, the screws
may be damaged or broken.
For delicate operations, such as removing a par-
tially stripped screw, use a low torque setting.
For operations such as drilling into hardwood,
use a higher torque setting.
LED WORKLIGHT (FIG. 11)
Your tool is
equipped with a
light that turns
on automatically
when the switch
is activated to
provide better
visibility when
drilling/driving.
DRILLING (FIG.
12)
WARNING:
To reduce the
risk of injury, al-
ways use the side
handle when
using this tool.
Always hold it
securely.
Ensure that the
side handle is
tightened se-
curely before
each use.
1. Check that the direction-of-rotation selector
for the correct setting.
2. Secure the material to be drilled in a vise or
with clamps to keep it from turning as the drill
bit rotates.
3. Hold the drill firmly and place the bit at the
point to be drilled.
4. Depress the trigger switch to start the drill.
5. Move the drill bit into the workpiece, apply-
ing only enough pressure to keep the bit cut-
ting. Do not force the drill or apply side pressure
to elongate a hole.
Let the tool do the work.
6. When drilling hard, smooth surfaces, use a
center punch to mark the desired location of the
