Working Advice

 Exercise caution when cutting slots in structural walls;
see Section "Information on Structures".
 Do not strain the machine so heavily that it comes to a
standstill.
 After heavily straining the power tool, continue to run
it at no-load for several minutes to cool down the acces-
sory.
 For cutting-depths greater than 20 mm in hard materi-
als, e.g., concrete, apply several worksteps so that the
motor is not overloaded.
 Clamp the workpiece if it does not remain stationary
due to its own weight.
 The machine may only be used for dry cutting.
 Diamond cutting discs become very hot during opera-
tion; do not touch them until they have cooled down.
Protect the cutting disc against impact, shock and grease. Do
not subject the cutting disc to lateral pressure.
Do not brake coasting diamond cutting discs by applying side-
ward pressure.
For cutting especially hard material, e. g., concrete with high
pebble content, the diamond cutting disc can overheat and
become damaged as a result. This is clearly indicated by cir-
cular sparking, rotating with the diamond cutting disc.
In this case, interrupt the cutting process and allow the dia-
mond cutting disc to cool by running the machine for a short
time at maximum speed with no load.
Noticeably decreasing work progress and circular sparking
are indications of a diamond cutting disc that has become
dull. Briefly cutting into abrasive material (e. g. lime-sand
brick) can resharpen the disc again.
Direction of Cut (see figure C)
The machine must always work in an up-grinding motion. Oth-
erwise, the danger exists of it being pushed uncontrolled out
of the cut.
Information on Structures
Slots in structural walls are subject to the Standard DIN 1053
Part 1, or country-specific regulations.
These regulations are to be observed under all circumstanc-
es. Before beginning work, consult the responsible structural
engineer, architect or the construction supervisor.

Maintenance and Service

Maintenance and Cleaning
 Before any work on the machine itself, pull the mains
plug.
 For safe and proper working, always keep the machine
and ventilation slots clean.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
Please store and handle the accessory(-ies) carefully.
