Use and Care Manual

OPERATION
LED LIGHT
See Figure 8, page 11.
The LEDs emit light from the front of the chuck 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
See Figure 9, page 11.
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,
for drilling in wood or masonry, and for hammer drilling.
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.
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.
SELECTING DRILL, DRIVE, OR HAMMER MODE
See Figure 11, page 12.
 Select drill mode for drilling and other heavy duty
applications.
 Select drive mode for driving screws.
 Select hammer mode for hammer drilling.
Choose 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 12, page 12.
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.
WARNING:
Do not drive a screw where there is likely to be
hidden wiring behind the surface. Contact with a
“live” wire will make exposed metal parts of the tool
“live” and possibly shock the operator. If you must
drive a screw where hidden wire may be present,
always hold tool by insulated gripping surfaces
(handle) when performing the operation to prevent
a shock to the operator.
 Depress the switch trigger to start the drill.
 Move the bit into the workpiece, applying only enough
pressure to keep the bit cutting or driving the screw. Do
not force the drill or apply side pressure to elongate a
hole. Let the tool do the work.
WARNING:
When drilling, be prepared for binding at bit
breakthrough. When these situations occur, drill
has a tendency to grab and kick opposite to the
direction of rotation and could cause loss of control
when breaking through material. If not prepared,
this loss of control can result in possible serious
injury.
