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.
