OPERATION
INSTALLING/REMOVING BATTERY PACK
See Figure 5, page 11.
 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 in 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 6 - 7, page 11.
The arrows on the keyless chuck indicate which direction
to rotate the chuck body 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 body to close and tighten the chuck
jaws.
WARNING:
Do not hold the chuck body with one hand and use
the power of the drill to tighten the chuck jaws on
the drill bit. The chuck body 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.
LED LIGHT
See Figure 8, page 11.
The LED light, located on the front of the tool base, illumi-
nates when either the switch trigger or grip light switch is
depressed.
If the drill is not in use, the time-out feature will cause the
light to start fading and then shut off.
The LED light illuminates only when there is a charged bat-
tery pack in the tool.
TWO-SPEED GEAR TRAIN (HI-LO SWITCH)
See Figure 9, page 11.
 Select LO (1) speed for applications requiring higher
power and torque.
 Select HI (2) speed for fast drilling or driving applications.
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 10, page 11.
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.
There are twenty-four torque indicator settings located on
the front of the drill. Rotate the torque adjustment ring to
the proper torque setting for the type of material and size
of screw you are using.
• 1 - 4 For driving small screws
• 5 - 8 For driving screws into soft material
• 9 - 12 For driving screws into soft and hard
materials
• 13 - 16 For driving screws into hard wood
• 17 - 24 For driving large screws
SELECTING DRILL, DRIVE, OR HAMMER MODE
See Figure 11, page 12.
The mode selector allows you to quickly switch from drill
mode to drive or hammer mode.
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: LO (1) or HI (2).
 Choose the correct mode: drill, drive or hammer.
NOTE: The hammer drill has not been designed for reverse
hammering.
