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.
Diamond drill safety warnings
Safety instructions for all operations
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 may contact hidden wiring or its own cord.
Cutting accessory contacting a "live" wire may make ex-
posed 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 warnings
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.
Wear hearing protection when diamond drilling. Ex-
u
posure to noise can cause hearing loss.
When the bit is jammed, stop applying downward
u
pressure and turn off the tool. Investigate and take cor-
rective actions to eliminate the cause of the bit jamming.
When restarting a diamond drill in the workpiece
u
check that the bit rotates freely before starting. If the
bit is jammed, it may not start, may overload the tool, or
may cause the diamond drill to release from the work-
piece.
When drilling through walls or ceilings, ensure to pro-
u
tect persons and the work area on the other side. The
bit may extend through the hole or the core may fall out
on the other side.
Wear non-skid shoes. This prevents injuries that can oc-
u
cur from slipping on smooth surfaces.
Bosch Power Tools
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
service centre.
Pay attention that neither persons in the working area
u
nor the power tool itself come into contact with the
water that comes out.
Take care that water-conducting hoses and connec-
u
tion elements are in proper condition. Replace dam-
aged or worn parts before the next use. Water escaping
from parts of the power tool will increase the risk of elec-
tric shock.
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.
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.
Always wait until the power tool has come to a com-
u
plete stop before placing it down. The application tool
can jam and cause you to lose control of the power tool.
Connect the power tool to a mains supply that is prop-
u
erly connected to earth. The socket and extension cable
must have a fully functioning protective conductor.
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.

Read all the safety and general instructions.
Failure to observe the safety and general in-
structions may result in electric shock, fire
and/or serious injury.
Please observe the illustrations at the beginning of this oper-
ating manual.

Intended use

In conjunction with diamond wet-drilling core bits and a wa-
ter supply, the power tool is intended for wet drilling in con-
crete and reinforced concrete. Overhead drilling with a wa-
ter supply is not permitted.
