OPERATION
INSTALLING/REMOVING BATTERY PACK
See Figure 2, page 9.
 Lock the switch trigger.
 Insert the battery pack into the product as shown.
 Make sure the latches on each side of the battery pack
snap into place and that battery pack is secured in the
product before beginning operation.
 Depress the latches to remove the battery pack.
INSTALLING/REMOVING BITS
See Figures 3 - 4, page 9.
The arrows on the keyless chuck indicate which direction
to rotate the chuck sleeve to tighten or release the drill bit.
Do not use a wrench to tighten or loosen the chuck jaws.
 To install bits, lock the switch trigger.
 Open or close the chuck jaws until the opening is slightly
larger than the bit size you intend to use.
 Raise the front of the drill slightly and insert the drill bit.
WARNING:
Make sure to insert the drill bit straight into the
chuck jaws. Do not insert the drill bit into the chuck
jaws at an angle, then tighten. This could cause
the drill bit to be thrown from the drill, resulting in
possible serious personal injury or damage to the
chuck.
 Rotate the chuck sleeve to close and tighten the chuck
jaws.
WARNING:
Do not hold the chuck sleeve with one hand and use the power of the drill to tighten the chuck
jaws on the drill bit. The chuck sleeve could slip
in your hand, or your hand could slip and come in
contact with the rotating drill bit. This could cause
an accident resulting in serious personal injury.
 To remove bits, lock the switch trigger and open the
chuck jaws.
 The bit provided with the drill can be placed in the storage
area, located on the rear base of the drill.
TWO-SPEED GEAR TRAIN
(HIGH-LOW SWITCH)
See Figure 5, page 10.
 Select Low (1) speed for applications requiring higher
power and torque, such as driving screws and drilling in
metal.
 Select High (2) speed for fast drilling or driving
applications, for drilling in wood or masonry, and for
hammer drilling.
NOTE: Running at low speeds under constant usage may
cause the drill to become overheated. If this occurs, cool the
drill by running it without a load and at full speed.
NOTICE:
Never change speeds while the tool is running.
Failure to obey this caution could result in serious
damage to the drill.
ADJUSTING TORQUE
See Figure 6, page 10.
When using the hammer drill for various driving applications,
it becomes necessary to increase or decrease the torque
to help prevent the possibility of damaging screw heads,
threads, workpiece, etc. In general, torque intensity should
correspond to the screw diameter. If the torque is too high or
the screws too small, the screws may be damaged or broken.
The torque is greater when the torque adjustment ring is
set on a higher setting. The torque is less when the torque
adjustment ring is set on a lower setting.
NOTE: The torque adjustment ring only functions in drive
mode.
SELECTING DRILL, DRIVE, OR HAMMER MODE
See Figure 7, page 10.
Drill mode should be used for drilling and other heavy duty
applications. Drive mode should be used for driving screws.
Hammer mode should be used for hammer drilling.
Select the option that best matches the type of bit, fastener,
and material you will be using.
 Choose your application.
 Choose the correct speed: Low (1) or High (2).
 Choose the correct mode: drill, drive or hammer.
NOTE: The hammer drill has not been designed for reverse
hammering.
Use carbide-tipped bits and select hammer mode when
drilling in hard materials such as brick, concrete, etc.
Use carbide-tipped bits and select drill mode when drilling
in materials with hard, brittle surfaces such as tile, etc.
Use twist drills, hole saws, etc. and drill mode when drilling
in soft materials.
DRILLING/DRIVING SCREWS
See Figure 8, page 10.
 Check the direction of rotation selector for the correct
setting (forward or reverse).
 Use Low (1) speed for high torque applications and
High (2) speed for fast drilling or driving applications.
Refer to Two-Speed Gear Train and Adjusting Torque.
 Secure the workpiece in a vise or with clamps to keep it
from turning as the bit rotates.
 Hold the drill firmly and place the bit at the point to be
drilled, or where the screw is to be driven.
