Machine-Specific Safety Warnings; Functional Description; Intended Use; Product Features - Bosch PSB 650 RA Bedienungsanleitung

f) Keep cutting tools sharp and clean. Prop-
erly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.
g) Use the power tool, accessories and tool
bits etc. in accordance with these instruc-
tions, taking into account the working con-
ditions and the work to be performed. Use
of the power tool for operations different from
those intended could result in a hazardous situ-
ation.
5) Service
a) Have your power tool serviced by a quali-
fied repair person using only identical
replacement parts. This will ensure that the
safety of the power tool is maintained.
Machine-specific
Safety Warnings
Wear hearing protection when using impact
drills. The influence of noise can lead to loss of
hearing.
Always use the auxiliary handle supplied with
the machine. Loss of control can cause personal
injury.
Use appropriate detectors to determine if util-
ity lines are hidden in the work area or call the
local utility company for assistance. Contact
with electric lines can lead to fire and electric shock.
Damaging a gas line can lead to explosion. Pene-
trating a water line causes property damage or may
cause an electric shock.
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 power tool only by the insulated
gripping surfaces when performing an opera-
tion where the cutting tool may contact hid-
den wiring or its own power cord. Contact with
a "live" wire will also make exposed metal parts of
the power tool "live" and shock the operator.
When working with the machine, always hold
it firmly with both hands and provide for a
secure stance. The power tool is guided more
secure with both hands.
Secure the workpiece. A workpiece clamped
with clamping devices or in a vice is held more
secure than by hand.
Do not work materials containing asbestos.
Asbestos is considered carcinogenic.

Take protective measures when dust can
develop during working that is harmful to
one's health, combustible or explosive. Exam-
ple: Some dusts are regarded as carcinogenic.
Wear a dust mask and work with dust/chip extrac-
tion when connectable.
Keep your workplace clean. Blends of materials
are particularly dangerous. Dust from light alloys
can burn or explode.
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.
Never use the machine with a damaged cable.
Do not touch the damaged cable and pull the
mains plug when the cable is damaged while
working. Damaged cables increase the risk of an
electric shock.
Read all safety warnings and all
instructions. Failure to follow the warn-
ings and instructions may result in electric
shock, fire and/or serious injury.
