TWO SPEED GEAR TRAIN
See Figure 9, page 13.
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 13.
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 14.
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.
OPERATION
R8611506 HAMMER DRILL
INSTALLING/REMOVING BITS
See Figures 6 - 7, page 13.
A bit storage area is located on the base of the tool.
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 and remove the
battery pack.
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 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.
LED GRIP LIGHT
See Figure 8, page 13.
The LED light illuminates when either the switch trigger or
LED grip light switch is depressed and there is a charged
battery in the tool. If the tool is not in use, the time-out feature
will cause the light to start fading and then shut off.

DIRECTION OF ROTATION SELECTOR
(FORWARD/REVERSE/CENTER LOCK)
See Figure 5, page 13 (R8611506).
See Figure 3, page 15 (R86039).
Set the direction of rotation selector in the
OFF
(center lock)
position to lock the switch trigger and help prevent accidental
starting when not in use.
Position the direction of rotation selector to the left of the
switch trigger for forward drilling. Position the selector to
the right of the switch trigger to reverse the direction.
NOTE:
The tool will not run unless the direction of rotation
selector is pushed fully to the left or right.
