Bit and Bit Holder
WARNING: Burn Hazard. ALWAYS wear gloves when
changing bits. Accessible metal parts on the tool and
bits may get extremely hot during operation. Small
bits of broken material may damage bare hands.
WARNING: Do not attempt to tighten or loosen drill
bits (or any other accessory) by gripping the front part
of the chuck and turning the tool on. Damage to the
chuck and personal injury may occur.
The rotary hammer can be fitted with various chisel bits
depending on 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.

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.
Overload Clutch
In case of jamming of a drill bit, the drive to the drill spindle
is interrupted by the overload clutch. Due to the resulting
forces, always hold the tool with both hands and take a
firm stance. After the overload, release and depress the
trigger to re-engage drive.
WARNING: Drill may stall if overloaded causing a
sudden twist. Always expect the stall. Grip the drill
firmly to control the twisting action and avoid injury.
