OPERATION
TO REMOVE BITS
See Figure 7, page 15.
 Unplug the drill.
 Loosen the chuck jaws using the chuck key provided.
 Remove the drill bit.
 Remove the chuck key.
USING THE AUXILIARY HANDLE ASSEMBLY
See Figure 9, page 15.
An auxiliary handle assembly is packed with the drill for
ease of operation and to help prevent loss of control. The
handle can be rotated 360°, and it can also be mounted on
the opposite side for left hand use.
To adjust the auxiliary handle assembly:
 Loosen the auxiliary handle assembly by turning the knob
counterclockwise.
 Rotate the auxiliary handle assembly to the desired
location.
 Tighten the auxiliary handle assembly securely by turning
the knob clockwise.
Be sure the handle assembly is securely tightened against
the depth stop clamp. This secures the handle assembly.
NOTE: For convenience and ease of starting threads, the
hex nut has been trapped inside the molded slot in the
handle assembly.
ADJUSTING THE DEPTH STOP ROD
See Figure 9, page 15.
Follow these steps to adjust the depth stop rod.
 Press the depth stop rod release button.
 Adjust the depth stop rod so that the drill bit extends be-
yond the end of the rod to the required drilling depth.
 Release the depth stop rod release button.
NOTE: When properly installed, the teeth on the depth stop
rod should be aligned with the teeth indicator on the depth
stop clamp.
Adjust the depth stop rod so that the drill bit extends beyond
the end of the rod to the required drilling depth.
When drilling holes with the depth stop rod installed, the
desired hole depth has been reached when the end of the
rod comes in contact with the surface of the workpiece.
SELECTING HAMMER MODE OR DRILLING
MODE
See Figure 10, page 15.
To adjust for type of drilling, slide the selector on top of the
motor housing to hammer mode or drilling mode. The ham-
mer mode symbol is on the right and the drill bit symbol is
on the left.
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, tile, concrete, etc.
Select normal drill mode when drilling with twist drills, hole
saws, etc., in soft materials.
ANTI-VIBRATION SYSTEM
See Figure 11, page 15.
The hammer drill is equipped with an anti-vibration system
that absorbs impacts while drilling. When sharp impacts hap-
pen, the hammer drill body will flex, as shown in figure 11.
LOCk-ON BUTTON
See Figure 12, page 15.
This drill is equipped with a lock-on feature, which is con-
venient for continuous drilling for extended periods of time.
To lock-on:
 Depress the switch trigger.
 Push in and hold the lock-on button, located on the side
of the handle.
 Release the switch trigger.
 Release the lock-on button and the drill will continue
running.
 To release the lock, depress and release the switch
trigger.
If the lock-on feature is engaged during use and the drill
becomes disconnected from the power supply, disengage
the lock-on feature immediately.
WARNING:
Before connecting the drill to a power supply
source, always check to be sure it is not in lock-on
position (depress and release the switch trigger).
Failure to ensure that it is not locked-on could
result in accidental starting of the drill resulting
in possible serious injury. Do not lock the switch
trigger in applications where the drill may need to
be suddenly stopped.
DRILLING
See Figure 13, page 15.
 Depress and release the switch trigger to be sure the drill
is in the OFF position before connecting it to a power
supply.
 Check the direction of rotation selector for the correct
setting (forward or reverse).
 Secure the material to be drilled in a vise or with clamps
to keep it from turning as the drill bit rotates.
 Plug the drill into power supply. Hold the drill firmly and
place the bit at the point to be drilled.
 Depress the switch trigger to start the drill.
 Move the drill bit into the workpiece, applying only enough
pressure to keep the bit cutting. Do not force the drill or
apply side pressure to elongate a hole. Let the tool do
the work.
