or posts. Should the bit become bound or
jammed in the work, the reaction torque of
the tool could crush your hand or leg.
If the bit becomes bound in the
workpiece, release
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.
Do not use dull or damaged bits and
accessories. Dull or damaged bits have a
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.
Before using battery charger, read all
instructions and cautionary markings on

your product or direct replacement as
listed in the catalog or this manual. Do not
substitute any other charger. Use only Bosch
approved chargers with your product. See
Functional Description and Specifications.
Do not disassemble charger or operate the
charger if it has received a sharp blow,
been dropped or otherwise damaged in any
way. Replace damaged cord or plugs

activities contains chemicals known to
cause cancer, birth defects or other
reproductive harm. Some examples of
these chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks and cement
and other masonry products, and
• Arsenic and chromium from chemically-
treated lumber.
Your risk from these exposures varies,
depending on how often you do this type of
work. To reduce your exposure to these
chemicals: work in a well ventilated area, and
work with approved safety equipment, such
as those dust masks that are specially
designed to filter out microscopic particles.
Battery/Charger
otherwise damaged, do not insert into
charger. Battery short or fire may result.
Charge only Bosch approved rechargeable
batteries. See Functional Description and
Specifications. Other types of batteries may
burst causing personal injury and damage.
Charge battery pack in temperatures above
+32 degrees F (0 degrees C) and below
+113 degrees F (45 degrees C). Store tool
and battery pack in locations where
temperatures will not exceed 120 degrees F
(49 degrees C). This is important to prevent
serious damage to the battery cells.
Battery leakage may occur under extreme
usage or temperature conditions. Avoid
contact with skin and eyes. The battery
liquid is caustic and could cause chemical
burns to tissues. If liquid comes in contact with
skin, wash quickly with soap and water. If the
