Hold power tool by insulated gripping surfaces
when performing an operation where the cutting
tool may contact hidden wiring or its own cord.
Contact with a "live" wire will also make exposed metal
parts of the power tool "live" and shock the operator.
Use clamps or another practical way to secure and
support the workpiece to a stable platform. Holding
the work by hand or against your body leaves it unstable
and may lead to loss of control.
Before drilling into walls, floors or ceilings check for the
location of wiring and pipes.
Avoid touching the tip of a drill bit just after drilling, as it
may be hot.

Selecting the direction of rotation (fig. D)
For drilling and for tightening screws, use forward (clockwise)
rotation. For loosening screws or removing a jammed drill bit,
use reverse (counterclockwise) rotation.
To select forward rotation, push the forward/reverse
