Bosch GBM 50-2 Professional Notice Originale page 11

any adjustments to the power tool or changing ac-
cessories. Accidents can occur when power tools are
started unintentionally.
When using the power tool for overhead applications,
u
two persons are always required.
Secure the power tool with a safety strap when
u
drilling into vertical or sloped surfaces, or working
overhead. In the event of a power failure or overload, the
magnet retention force is not maintained. The power tool
may fall over and cause accidents.
Danger of the power tool falling down due to sudden
u
pendular motion of the power tool. When working on a
scaffold, the power tool can be subject to a sudden pen-
dular motion when the drill starts or in case of a power
failure. Secure the power tool with the provided safety
strap. Secure yourself against falling down by applying a
safety rope/belt.
The surface must be smooth and clean. Smooth out
u
coarse irregularities, e. g., welding spatter and re-
move loose rust, dirt and grease. The holding force of
the magnet applies only for appropriate surfaces.
Secure the power tool on a stable, even and horizontal
u
surface. If the power tool can slip or shake, the applica-
tion tool cannot be operated evenly and safely.
Keep the work surface clean, including the workpiece.
u
Sharp-edged drilling chips and other objects may cause
injury. Material mixtures are particularly hazardous. Light
metal dust may catch fire or explode.
Do not touch the application tool after working before
u
it has cooled. The application tool becomes very hot
while working.
Do not touch the drill core that will be automatically
u
ejected through the guide pin once the work process
has ended. The drill core can become very hot.
Check the cable regularly and have a damaged cable
u
repaired only by an authorised customer service
agent for Bosch power tools. Replace damaged exten-
sion cables. This will ensure that the safety of the power
tool is maintained.
Store the power tool safely when it is not in use. The
u
storage location must be dry and lockable. This pre-
vents the power tool from storage damage, and from be-
ing operated by untrained persons.
Never use the power tool if the cable is damaged. Do
u
not touch the damaged cable and pull out the mains
plug if the cable is damaged while working. Damaged
cables increase the risk of an electric shock.
Products sold in GB only:
Your product is fitted with an BS 1363/A approved electric
plug with internal fuse (ASTA approved to BS 1362).
If the plug is not suitable for your socket outlets, it should be
cut off and an appropriate plug fitted in its place by an au-
thorised customer service agent. The replacement plug
should have the same fuse rating as the original plug.
Bosch Power Tools
The severed plug must be disposed of to avoid a possible
shock hazard and should never be inserted into a mains
socket elsewhere.
The retention of the magnets depends on the thick-
u
ness of the workpiece. They hold best on low-carbon
steel with a thickness of at least 20 mm. When drilling
into thinner steel, an additional steel plate (of at least 100
x 200 x 20 mm) must be placed under the magnetic base.
Ensure that the steel plate cannot fall off.
Metal chips and other debris will seriously hamper
u
magnetic adhesion. Always ensure that the magnetic
base is clean.
Avoid the magnet releasing. Ensure that the magnetic
u
base has properly adhered to the work piece before be-
ginning drilling.
Do not switch off the magnetic power or use the re-
u
verse drilling function before the power tool comes to
a complete stop.
Other units used on the same receptacle will cause un-
u
even voltage that could lead to the magnet releasing.
Always use the power tool alone on the receptacle.
Avoid operating annular cutters without coolant fluid.
u
Always check coolant level before operating.
Protect the motor. Never allow coolant fluid, water, or
u
other contaminants enter the motor.
Metal chips are often very sharp and hot. Never touch
u
them with bare hands. Clean up with a magnetic chip
collector and a chip hook or other appropriate tool.
Never attempt to use the power tool with incorrect
u
current or abnormally low voltage. Check the name-
plate of the power tool to ensure that correct voltage and
frequency are used.
The power tool is delivered with a warning sign (see
u
table: "Symbols and their meaning").
Never make warning signs on the machine unrecognis-
u
able.
Do not direct the laser beam at persons or
animals and do not look directly into the
laser beam or at its reflection. Doing so
could lead to blindless, or could cause acci-
dents or damage to the eyes.
If laser radiation hits your eye, you must close your
u
eyes and immediately turn your head away from the
beam.
Do not make any modifications to the laser equip-
u
ment. The setting options described in these operating
instructions can be used safely.
Do not let children use the power tool unsupervised.
u
They could accidentally blind someone
