Active Vibration Control
For best vibration control, hold the tool as described in Proper
Hand Position.
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.
The hammer only needs enough pressure to engage the active
vibraton control. Applying too much pressure will not make
the tool drill or chip faster and active vibration control will
not engage.
