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.

injury, turn tool off and disconnect battery pack
before making any adjustments or removing/

the desired application. Use sharp drill bits only.
Bit Reccomendations
•
For wood, use twist bits, spade bits, power auger bits or
hole saws.
•
For metal, use high-speed steel twist drill bits or hole saws.
Use a cutting lubricant when drilling metals. The exceptions
are cast iron and brass which should be drilled dry.
•
For masonry, such as brick, cement, cinder block, etc., use
carbide-tipped bits rated for percussion drilling.
