Never operate the machine without the portable resid-
ual current device (PRCD) provided.
Products sold in GB only: Never operate the 110 V exe-
cution of the machine without isolation transformer ac-
cording 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.
Before starting work, check the proper function of the
portable residual current device (PRCD). Have a dam-
aged portable residual current device (PRCD) repaired
or replaced by your Bosch after-sales service agent.
Pay attention that neither persons in the working area
nor the power tool itself come into contact with the wa-
ter that comes out.
When wet drilling over-
head, the escaping water
must be collected. To do
this, insert the power tool in-
to a drill stand and mount a
water collecting ring (see
"Accessories/Spare Parts",
page 14).
Ensure that water-carrying hoses, connectors and the
water collection ring (accessory) are in immaculate
condition. Replace damaged or worn parts before the
next use. Water escaping from parts of the power tool will
increase the risk of electric shock.
Product Description and

Intended Use
In conjunction with diamond wet-drilling core bits and a water
supply, the power tool is intended for wet drilling in mineral
materials such as concrete, reinforced concrete or brickwork.
The power tool can be combined with an extraction device
(water collection ring and wet/dry vacuum cleaner).
The power tool must only be used together with the diamond
drill stand GCR 350.
Using an anchor, the drill stand for diamond drills can be fas-
tened to the floor, wall and overhead.
The drill stand for diamond drills can be attached to the floor
by means of vacuum (accessory) or (with an additional safe-
guard) against the wall. Attaching overhead is not permitted.
The drill stand for diamond drills can be attached to the floor
using the quick-clamping column. Attaching to a wall or over-
head is not permitted.
