PBLHM101 HAMMER DRILL
INSTALLING/REMOVING BITS
See Figures 5 - 6, page 12 (PBLHM101).
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 per-
sonal 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.
TWO-SPEED GEAR TRAIN
See Figure 7, page 12 (PBLHM101).
 Select low speed (1) for applications requiring higher
power and torque, such as driving screws and drilling in
metal.
 Select high speed (2) for fast drilling or driving applications
or for drilling in wood or masonry.
NOTICE:
Never change speeds while the tool is running. Failure
to obey this caution could result in serious damage to
the drill.
NOTE: If you have difficulty changing from one speed range
to the other, turn the chuck by hand until the gears engage.
OPERATION
ADJUSTING TORQUE
See Figure 7, page 12 (PBLHM101).
When using the hammer drill for various driving applications,
beginning with a lower torque setting helps 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 adjusted by rotating the adjusting ring.
The torque is greater when the adjusting ring is set on a
higher setting. The torque is less when the adjusting ring is
set on a lower setting.
Rotate the adjustment ring to the proper torque setting for
the type of material and size of screw you are using.

LED LIGHT
The LED light, located on the front of the tool base, illuminates
when the switch trigger 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 battery
pack in the tool.
DRILLING/DRIVING SCREWS
See Figure 8, page 12 (PBLHM101).
WARNING:
Always use the auxiliary handle when using this tool to
help resist torque reactions. Binding or stalling of this
product could lead to serious personal injury.
 Install the auxiliary handle.
 Check the direction of rotation selector for the correct
setting (forward or reverse).
 Select low speed (1) or high speed (2), depending on
your application. 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.
