Bosch Power Tools
Hammer Safety Warnings
Wear ear protectors.
Exposure to noise can cause hear-
ing loss.
Use auxiliary handle(s), if supplied with the tool.
Loss
of control can cause personal injury.
Hold the tool by the insulated gripping surfaces when
performing operations where the application tool or
the screw could contact hidden 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.
Additional Safety and Working In-
structions
Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
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.
Firmly tighten the auxiliary handle, hold the machine
firmly with both hands while working and keep proper
footing and balance at all times.
The machine is securely
guided with both hands.
Secure the workpiece.
A workpiece clamped with clamp-
ing devices or in a vice is held more secure than by hand.
For drilling without impact in wood, metal, ceramic and
plastic as well as for screwdriving, tools without SDS-plus
are used (e.g., drill bits with cylindrical shank). For these
tools, a keyless chuck or a key type drill chuck are re-
quired.
The quick change chuck is automatically locked. Check the
locking effect by pulling the quick change chuck.
Apply the power tool to the screw only when it is
switched off.
Rotating tool inserts can slip off.
Inserting SDS-plus Drilling Tools:
Check the latching by
pulling the tool.
To save energy, only switch the power tool on when using
it.
Replace a damaged dust protection cap immediately.
The dust protection cap largely prevents the penetration of
drilling dust into the tool holder during operation. When in-
serting the tool, pay attention that the dust protection cap
is not damaged.
Dust from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one’s health and cause allergic reactions, lead to res-
piratory infections and/or cancer.
Materials containing
asbestos may only be worked by specialists.
–
As far as possible, use a dust extraction system suitable
for the material.
–
Provide for good ventilation of the working place.
–
It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
Prevent dust accumulation at the workplace.
Dust can
easily ignite.
If the application tool should become blocked, switch
the machine off. Loosen the application tool.
Before switching on the power tool, make sure that the
application tool moves freely.
When switching on with a
blocked drilling tool, high torque reaction can occur.
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.
Products sold in GB only:
Your product is fitted with a
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
authorised 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.
Products sold in AUS and NZ only:
Use a residual current
device (RCD) with a rated residual current of 30 mA or
less.
