Personal safety
Stay alert, watch what you are doing and use common
u
sense when operating a power tool. Do not use a
power tool while you are tired or under the influence
of drugs, alcohol or medication. A moment of inatten-
tion while operating power tools may result in serious per-
sonal injury.
Use personal protective equipment. Always wear eye
u
protection. Protective equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing protection
used for appropriate conditions will reduce personal in-
juries.
Prevent unintentional starting. Ensure the switch is in
u
the off-position before connecting to power source
and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or en-
ergising power tools that have the switch on invites acci-
dents.
Remove any adjusting key or wrench before turning
u
the power tool on. A wrench or a key left attached to a
rotating part of the power tool may result in personal in-
jury.
Do not overreach. Keep proper footing and balance at
u
all times. This enables better control of the power tool in
unexpected situations.
Dress properly. Do not wear loose clothing or jew-
u
ellery. Keep your hair, clothing and gloves away from
moving parts. Loose clothes, jewellery or long hair can
be caught in moving parts. If devices are provided for the connection of dust ex-
u
traction and collection facilities, ensure these are con-
nected and properly used. Use of dust collection can re-
duce dust-related hazards.
Power tool use and care
Do not force the power tool. Use the correct power
u
tool for your application. The correct power tool will do
the job better and safer at the rate for which it was de-
signed.
Do not use the power tool if the switch does not turn it
u
on and off. Any power tool that cannot be controlled
with the switch is dangerous and must be repaired.
Disconnect the plug from the power source and/or the
u
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
u
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-
u
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.
Bosch Power Tools
Keep cutting tools sharp and clean. Properly main-
u
tained 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
u
accordance with these instructions, taking into ac-
count the working conditions and the work to be per-
formed. Use of the power tool for operations different
from those intended could result in a hazardous situation.
Service
Have your power tool serviced by a qualified repair
u
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
Hammer and Drill Safety Warnings
Safety instructions for all operations
Wear ear protectors. Exposure to noise can cause hear-
u
ing loss.
Use the auxiliary handle(s). Loss of control can cause
u
personal injury.
Brace the tool properly before use. This tool produces a
u
high output torque and without properly bracing the tool
during operation, loss of control may occur resulting in
personal injury.
Hold the power tool by insulated gripping surfaces,
u
when performing an operation where the cutting ac-
cessory or fasteners may contact hidden wiring or its
own cord. Cutting accessory or fasteners contacting a
"live" wire may make exposed metal parts of the power
tool "live" and could give the operator an electric shock.
Safety instructions when using long drill bits
Never operate at higher speed than the maximum
u
speed rating of the drill bit. At higher speeds, the bit is
likely to bend if allowed to rotate freely without contact-
ing the workpiece, resulting in personal injury.
Always start drilling at low speed and with the bit tip
u
in contact with the workpiece. At higher speeds, the bit
is likely to bend if allowed to rotate freely without contact-
ing the workpiece, resulting in personal injury.
Apply pressure only in direct line with the bit and do
u
not apply excessive pressure.Bits can bend causing
breakage or loss of control, resulting in personal injury.
Additional safety information
Use auxiliary handle(s), if supplied with the tool. Loss
u
of control can cause personal injury.
Hold the power tool firmly with both hands and make
u
sure you have a stable footing. The power tool can be
more securely guided with both hands.
Switch the power tool off immediately if the applica-
u
tion tool becomes blocked. Be prepared for high
torque reactions which cause kickback. The applica-
tion tool becomes blocked when it becomes jammed in
the workpiece or when the power tool becomes over-
loaded.
