Year of Manufacture

Soft start feature – D25901, D25902

The soft start feature allows the impact rate to build 
up more slowly, thus preventing the chisel or point 
from “bouncing” around on the masonry when 
starting up.

Active vibration control – D25901, 

D25902

The active vibration control 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.

DeWALT Tool Tag Ready (Fig. 1)

Optional Accessory

Your hammer comes with mounting holes ( g ) and 
fasteners for installing a DeWALT Tool Tag. You will 
need a T20 bit tip to install the tag. 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.

Electronic impact energy control – 

D25901 only (fig. 1)

The electronic impact energy control (c) offers the 
following advantages:

• 

use of smaller accessories without risk of 
breakage

• 

minimised break-out when chiselling soft or 
brittle materials

• 

optimal tool control for precise chiselling
