SHOCKS Active Vibration Control® System 
(Fig. A, F)
D25604, D25652, D25831, D25851
For best vibration control, hold the tool with one hand 
on the main handle
4
 and the other hand on the side 
handle
3
. 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 drill or chip faster and active vibration control will 
notengage.

In addition to the clutch, the 
DeWALT
 an anti-rotation 
system, E-Clutch®, 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
