OPERATION
R86116 HAMMER DRILL
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
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.
NOTA: Si tiene problemas para cambiar de un rango de
velocidad a otro, gire el portabrocas con la mano hasta que
los engranajes encajene.
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 11.
Select drill mode for drilling and other heavy duty
applications.
Select drive mode for driving screws.
Select hammer mode 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 12, page 11.
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.
