Trigger Switch (Fig. A)
To turn the tool on, squeeze the trigger switch
tool off, release the trigger switch. Your tool is equipped with
a brake. The chuck will stop as soon as the trigger switch is
fully released.
Variable Speed Trigger Switch
The variable speed trigger switch enables you to select
the best speed for a particular application. The farther you
squeeze the trigger switch, the faster the tool will operate.
For maximum tool life, use variable speed only for starting
holes or fasteners.
nOTE: Continuous use in variable speed range is not
recommended. It may damage the trigger switch and should
be avoided.
Forward/Reverse Control Button (Fig. A, H)
A forward/reverse control button
of bit rotation and also serves as a lock‑off button.
To select forward rotation, release the trigger switch
and depress the forward/reverse control button on the right
side of the tool.
To select reverse, depress the forward/reverse control
button on the left side of the tool.
The center position of the control button locks the tool
in the off position. When changing the position of the
control button, be sure the trigger is released.
nOTE: The first time the tool is run after changing the
direction of rotation, you may hear a click on start up. This is
normal and does not indicate a problem.
Worklight (Fig. I)

CAUTION: Do not stare into worklight. Serious eye
injury could result.
There is a worklight 7 located on the front of the tool. The
worklight is activated when the trigger switch is depressed,
and will automatically turn off 20 seconds after the trigger
switch is released. If the trigger switch remains depressed,
the worklight will remain on.

Mode Selector Knob (Fig. J)

CAUTION: Do not change to drill or hammerdrill
mode with a chisel bit in the chuck. Personal injury and
damage to tool may result.

CAUTION: Never change the mode while the unit
is running.
• For drilling (non‑percussion) rotate the mode selector
knob 5 in the down position until the line aligns with
the drill bit symbol
• For rotary hammer drilling (with percussion) rotate the
mode selector knob
aligns to the drill bit and hammer symbol
• For chipping mode, align arrow with the hammer
symbol 16
NOTE: The mode selector knob
hammer drilling or chipping mode at all times. There are no
operable positions in between.
Electronic Overload Protection
If the drill bit becomes jammed, the power to the drill
spindle will be interrupted by the activation of the electronic
overload protection. To reactivate the power to the drive
spindle, the tool's trigger should be released and then
depressed. Due to the resulting forces, always hold the tool
with both hands and take a firm stance.
SHOCKS Active Vibration Control®
System
For best vibration control, hold the tool as described in
Proper Hand Position and apply just enough pressure so the
damping device on the main handle is approximately mid
stroke. The hammer only needs enough pressure to engage
the active vibration control. Applying too much pressure will
not make the tool actuate faster and active vibration control
will not engage.
SDS plus® Chuck (Fig. K)

of broken material may damage bare hands.
To insert bit, insert shank of bit about 3/4" (19 mm) into
chuck 17 . Push and rotate bit until it locks in place. The bit
will be securely held.
