the Drilling Operation
1.
Use only well-sharpened bits that are
in good condition and appropriate to
the task.
2.
Use firm pressure when drilling, but
do not press too hard. Too much
pressure will not help the process
and will cause the bit to overheat,
may cause the bit to bend or break,
cause undue strain on the tool, and
may damage the bit or work piece.
Pressing too hard may stall the mo-
tor. WARNING: If the motor stalls,
release the Trigger immediately, to
prevent damage to the tool.
3.
Always drill in a straight line. Bending
or twisting the bit while drilling may
cause the bit to bend or break and
may damage the work piece.
4.
Use the Auxiliary handle whenever
possible for better tool control.
5.
Back off your pressure when you are
about to penetrate the work piece.
6.
Keep the motor running when pull-
ing the bit out of a completed hole to
prevent the bit from jamming.
