If the bit becomes bound in the workpiece,
release the trigger immediately, reverse the
direction of rotation and slowly squeeze
the trigger to back out the bit. Be ready for
a strong reaction torque. The drill body will
tend to twist in the opposite direction as the
drill bit is rotating.
Do not grasp the tool or place your hands
too close to the spinning chuck or drill bit.
Your hand may be lacerated.
When installing a bit, insert the shank of
the bit well within the chuck. If the bit is not
inserted deep enough, the grip of the chuck
over the bit is reduced and the loss of control is
increased. After bit insertion, pull on bit to
ensure it is locked.
GFCI and personal protection devices like
electrician's rubber gloves and footwear will
further enhance your personal safety.
Do not use AC only rated tools with a DC
power supply. While the tool may appear to
work, the electrical components of the AC
rated tool are likely to fail and create a hazard
to the operator.
Keep handles dry, clean and free from oil
and grease. Slippery hands cannot safely
control the power tool.
Develop a periodic maintenance schedule
for your tool. When cleaning a tool be
careful not to disassemble any portion of
the tool since internal wires may be
misplaced or pinched or safety guard return
springs may be improperly mounted.
Certain cleaning agents such as gasoline,
carbon tetrachloride, ammonia, etc. may
damage plastic parts.
Ensure the switch is in the off position

greater tendency to bind in the workpiece.
When removing the bit from the tool avoid
contact with skin and use proper protective
gloves when grasping the bit or accessory.
Accessories may be hot after prolonged use.
Check to see that keys and adjusting
wrenches are removed from the drill before
switching the tool "ON". Keys or wrenches
can fly away at high velocity striking you or a
bystander.
Do not run the drill while carrying it at your
side. A spinning drill bit could become
entangled with clothing and injury may result.
