ASSEMBLY AND ADJUSTMENTS

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
start‑up can causeinjury.

WARNING: Use only DeWALT batteries andchargers.
Anti-Rotation System and Service Indicator LED
(Fig. A)
Your rotary hammer has two LEDs, indicating the anti-rotation
system and a service indicator. Refer to the table for more
information on LEDfunctionality.
LED Function Description
Red
(permanently on)
Anti-rotation system
The red anti-rotation system
indicator LED
11
lights up
when anti-rotation isengaged.
Yellow
(permanently on)
Service required
The yellow service indicator
LED
12
lights up to indicate
the tool needs servicing within
the next 10 hours of use (new
lubrication and hammer
mechanism sealing).
Yellow
(flashing)
Service exceeded
With the service indicator lit,
after a further 10 hours use
the service indicator flashes to
indicate the tool has exceeded
the required service interval.
Anti-Rotation System
In addition to the clutch, an anti-rotation system offers increased
user comfort through an on-board, anti-rotation technology
capable of detecting if the user loses control of the hammer.
When a jam is detected, the torque and speed are stopped
instantly. This feature prevents self rotation of the tool.
The red anti-rotation system indicator
11
will illuminate to
indicatestatus.
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.
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 electronic speed and impact control 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 orchiselled.
• When chiselling or drilling in soft, brittle materials or when
minimum break-out is required, set the dial to a low setting;
• When breaking or drilling in harder materials, set the dial to
a highsetting.
DeWALT Tool Tag Ready (Fig.A)
Optional Accessory
Your hammer comes with mounting holes
13
and
fasteners
12
for installing a DeWALT Tool Tag. You will need a
T20 bit tip to install the tag.

WARNING: Use only original fasteners. Longer screws
increase the risk of electrical shock or damage to the tool.
The DeWALT Tool Tag is designed for tracking and locating
professional power tools, equipment, and machines using
the DeWALT Tool Connect™ app. For proper installation of the
DeWALT Tool Tag refer to the DeWALT Tool Tagmanual.
Active Vibration Control (AVC) System (Fig. A)
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 active vibration control
16
neutralises rebound vibration
from the hammer mechanism. Lowering hand and arm
vibration, it allows more comfortable use for longer periods of
time and extends the life of theunit.
The hammer only needs enough pressure to engage the active
vibration control. Applying too much pressure will not make
the tool drill or chip faster and active vibration control will
notengage.
Soft Start Feature
The soft start feature allows the tool to accelerate slowly, thus
preventing the drill bit from walking off the intended hole
position whenstarting.
The soft start feature also reduces the immediate torque
reaction transmitted to the gearing and the operator if the
hammer is started with the drill bit in an existinghole.
