Disconnect the plug from the power source and/or the
battery pack from the power tool before making any
adjustments, changing accessories, or storing power
tools. Such preventive safety measures reduce the risk of
starting the power tool accidentally.
Store idle power tools out of the reach of children and
do not allow persons unfamiliar with the power tool or
these instructions to operate the power tool. Power
tools are dangerous in the hands of untrained users.
Maintain power tools. Check for misalignment or bind-
ing of moving parts, breakage of parts and any other
condition that may affect the power tool's operation. If
damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power
tools.
Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to bind
and are easier to control.
Use the power tool, accessories and tool bits etc. in ac-
cordance with these instructions, taking into account
the working conditions and the work to be performed.
Use of the power tool for operations different from those
intended could result in a hazardous situation.
Battery tool use and care
Recharge only with the charger specified by the manu-
facturer. A charger that is suitable for one type of battery
pack may create a risk of fire when used with another bat-
tery pack.
Use power tools only with specifically designated bat-
tery packs. Use of any other battery packs may create a
risk of injury and fire.
When battery pack is not in use, keep it away from oth-
er metal objects, like paper clips, coins, keys, nails,
screws or other small metal objects, that can make a
connection from one terminal to another. Shorting the
battery terminals together may cause burns or a fire.
Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally oc-
curs, flush with water. If liquid contacts eyes, addition-
ally seek medical help. Liquid ejected from the battery
may cause irritation or burns.
Service
Have your power tool serviced by a qualified repair per-
son using only identical replacement parts. This will en-
sure that the safety of the power tool is maintained.
Safety Warnings for Drills and Screwdrivers
GSB 18V-21
Wear ear protectors when impact drilling. Exposure to
noise can cause hearing loss.
GSR 18V-21/ GSB 18V-21
Hold power tool by insulated gripping surfaces when
performing an operation where the cutting accessory
or fastener may contact hidden wiring. Cutting accesso-
ry and fasteners contacting a "live" wire may make ex-
Bosch Power Tools
posed metal parts of the power tool "live" and could give
the operator an electric shock.
Use auxiliary handle(s), if supplied with the tool. Loss
of control can cause personal injury.
Use appropriate detectors to determine if utility lines
are hidden in the work area or call the local utility com-
pany for assistance. Contact with electric lines can lead
to fire and electric shock. Damaging a gas line can lead to
explosion. Penetrating a water line causes property dam-
age.
Switch off the power tool immediately when the tool
insert jams. Be prepared for high reaction torque that
can cause kickback. The tool insert jams when:
– the power tool is subject to overload or
– it becomes wedged in the workpiece.
Hold the machine with a firm grip. High reaction torque
can briefly occur while driving in and loosening screws.
Secure the workpiece. A workpiece clamped with clamp-
ing devices or in a vice is held more secure than by hand.
Always wait until the machine has come to a complete
stop before placing it down. The tool insert can jam and
lead to loss of control over the power tool.
Do not open the battery. Danger of short-circuiting.
Protect the battery against heat, e. g., against
continuous intense sunlight, fire, water, and
moisture. Danger of explosion.
In case of damage and improper use of the battery, va-
pours may be emitted. Ventilate the area and seek
medical help in case of complaints. The vapours can irri-
tate the respiratory system.
Use the battery only in conjunction with your Bosch
power tool. This measure alone protects the battery
against dangerous overload.
The battery can be damaged by pointed objects such as
nails or screwdrivers or by force applied externally. An
internal short circuit can occur and the battery can burn,
smoke, explode or overheat.
