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.
D WALT Tool Tag Ready (Fig. A)
e
Optional Accessory
Your hammer comes with mounting holes
fasteners for installing a D WALT Tool Tag. You will need a
e
T15 bit tip to install the tag. Only use the screws provided.
The D WALT Tool Tag is designed for tracking and locating
e
professional power tools, equipment, and machines using
the D WALT Tool Connect™ app. For proper installation
e
and use of the D WALT Tool Tag refer to the D
e
Tag manual.
Electronic Speed and Impact Control (Fig. A)
The electronic speed and impact control allows the
use of smaller drill bits without the risk of bit breakage,
hammerdrilling into light and brittle materials without
shattering and optimal tool control for precise chiseling.
To set the speed dial 10 , turn the dial to the desired level.
The higher the number, the greater the speed and impact
energy. Dial settings make the tool extremely flexible and
adaptable for many different appli cations. The required
setting depends on the bit size and hardness of material
being drilled.
Overload Clutch
In case of jamming of a drill bit, the drive to the drill spindle
is interrupted by the overload clutch. Due to the resulting
forces, always hold the tool with both hands and take a
firm stance. After the overload, release and depress the
trigger to re-engage drive.

WARNING: Drill may stall if overloaded causing a
sudden twist. Always expect the stall. Grip the drill
firmly to control the twisting action and avoid injury.
