Bit Binding
A high rotational force occurs when a bit
binds. If the bit binds, the tool will be forced
in the opposite direction of the bit rotation.
Bits may bind if they are misaligned or when
they are breaking through a hole. Wood
boring bits can also bind if they run into
nails or knots. Be prepared for bit binding
situations.
WARNING!
High rotational force. To reduce
the risk of injury, always hold or
brace securely. Always use side
handle on tools.

To reduce the chance of bit binding:
• Use sharp bits. Sharp bits are less
likely to bind when drilling.
• Use the proper bit for the job. There
are bits that are designed for specific
purposes.
• Use caution when drilling pitchy,
knotty, wet or warped material or
when drilling in material that may con-
tain nails.

Typical Bracing Methods
Driving Screws and Nut Running
Drill a pilot hole when driving screws into
thick or hard materials. Set the torque se-
lector collar to the proper position and set
the speed to low. Use the proper style and
size screwdriver bit for the type of screw
you are using.
With the screwdriver bit in the screw, place
the tip of the screw on the workpiece and
apply firm pressure before pulling the trig-
ger. Screws can be removed by reversing
the motor.
Overloading
Continuous overloading may cause per-
manent damage to tool or battery pack.
