OPERATION
VARIABLE SPEED SWITCH TRIGGER
See Figure 3, page 11.
The variable speed switch trigger delivers higher speed with
increased trigger pressure and lower speed with decreased
trigger pressure.
To turn the hammer drill ON, depress the switch trigger. To
turn it OFF, release the switch trigger and allow the chuck
to come to a complete stop.
The LED light, located on the base of the tool, will turn on
when the switch trigger is depressed.
NOTE: A whistling or ringing noise coming from the switch
during use is a normal part of the switch function.
NOTE: Running at low speeds under constant usage may
cause the hammer drill to become overheated. If this occurs,
cool the hammer drill by running it without a load and at
full speed.
DIRECTION OF ROTATION SELECTOR
(FORWARD/REVERSE/CENTER LOCK)
See Figure 3, page 11.
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 hammer drill will not run unless the direction of
rotation selector is pushed fully to the left or right.
NOTICE:
To prevent gear damage, always allow the chuck
to come to a complete stop before changing the
direction of rotation.
WARNING:
Battery tools are always in operating condition.
Lock the switch when not in use or carrying at your
side, when installing or removing the battery pack,
and when installing or removing bits.
INSTALLING/REMOVING BITS
See Figures 4 - 5, page 11.
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 hammer 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 hammer
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 hammer 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 hammer drill can be placed in

the storage area, located on the base of the hammer drill.
LED LIGHT
See Figure 6, page 12.
The LED light, located on the front of the tool base, illumi-
nates when the switch trigger is depressed.
If the hammer 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 7, page 12.
Select low speed (1) for applications such as drilling in

metal, and for applications requiring higher torque, such
as driving large screws.
Select high speed (2) for fast drilling or driving applica-

tions, 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 hammer drill.
NOTE: If you have difficulty changing from one speed range
to the other, turn the chuck by hand until the gears engage.
