OPERATION
Holding
tool
CAUTION:
This is
a
powerful tool. High torque is developed and
it
is important that the tool should be
securely held and properly braced.
Grasp the handle with one hand and the spade grip with the other hand. When drilling a
large hole with
a self-feed bit, etc., the side grip (auxiliary handle) should be used as a
brace to maintain safe control of the tool.
When
drilling action is forward (clockwise), the tool should be braced
to
prevent
a
counterclockwise reaction if the bit should bind. When reversing, brace the tool to prevent
a clockwise reaction. If the bit must be removed from a partially drilled hole, be sure the
tool is properly braced before reversing.
