Bosch GBM 50-2 Professional heavy duty Originalbetriebsanleitung Seite 21

Use suitable detectors to determine if utility lines are
u
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 or may cause an electric shock.
Never operate the power tool without the portable re-
u
sidual current device (PRCD) included in delivery.
Before beginning work, check that the portable resid-
u
ual current device (PRCD) is functioning properly.
Have any damaged portable residual current devices
(PRCDs) repaired or replaced by a Bosch after-sales ser-
vice agent.
Pay attention that neither persons in the working area
u
nor the power tool itself come into contact with the
water that comes out.
Wear non-skid shoes. This prevents injuries that can oc-
u
cur from slipping on smooth surfaces.
Products sold in GB only: Never operate the 110 V ex-
u
ecution of the machine without isolation transformer
according to EN/IEC 61558-1 and EN/IEC
61558-2-23. The isolation transformer must have a
grounded earth wire on the secondary winding side.
Never leave the tool unattended before it has come to
u
a complete stop. Drilling tools that are still running can
cause injuries.
Keep the drill cord away from the work area. Damaged
u
or entangled cords increase the risk of electric shock.
Do not overload the power tool or climb or stand on it.
u
Overloading or standing on the power tool can raise its
centre of gravity, causing it to tip over.
The power tool must only be operated on a mains sup-
u
ply with protective conductor and adequate dimen-
sioning.
Persons with cardiac pacemakers or other
medicinal implants may not use this power-
tool.
Carrying along metal parts and
watches is prohibited.
Disconnect the plug from the power source and/or re-
u
move the battery from the power tool before making
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-
Bosch Power Tools
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.
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.
