Intended Use - Bosch GNF 35 CA Operating Instructions Manual

Insert the mains plug only when the machine is
switched off.
Do not clamp the machine in a vice.
Always switch off the machine and allow to
come to a stop before placing it down.
Do not work with materials containing asbes-
tos.
Only use diamond cutting discs with a maxi-
mum permissible speed that is at least as high
as the no-load speed of the machine.
Check the diamond cutting discs before use.
The diamond cutting discs must be mounted in
exact alignment and be able to rotate freely.
Carry out a test run for at least 30 seconds
without any load. Do not use any diamond cut-
ting discs that are damaged, out-of-balance, or
vibrate.
Observe the dimensions of the diamond cut-
ting discs. The hole diameter must fit the
mounting flange 15. Do not use any reduction
parts or adapters.
Protect diamond cutting discs against impact,
shock and grease.
Apply the machine to the workpiece only when
switched on.
Keep hands away from the rotating diamond
cutting disc.
Pay attention to the direction of rotation. Al-
ways hold the machine so that sparks and
grinding dust fly away from the body.
Be careful when cutting grooves, e. g. in load-
carrying walls: See information on structures.
Do not drill, fasten or cut into blind areas
where electric, gas or water lines may exist.
Use appropriate detectors to determine if
these lines are hidden in the work area or
call the local utility company for assis-
tance.
Contacting electric lines may cause fire or
electric shock. Striking a gas line will probably
result in explosion. Breaking into a water pipe
will cause property damage or may cause an
electric shock.
Caution! Sparks can also reach combustible
materials that are covered.
Blocking the cutting disc leads to jerking reac-
tion forces on the machine. In this case switch
off the machine immediately.

Observe the manufacturer's instructions for
mounting and operating the diamond cutting
discs.
Caution! Diamond cutting discs do not stop
running immediately when the machine is
turned off. Do not exert any pressure against
the side of the diamond cutting discs.
The machine must be operated only with dust
extraction. In addition, wear a dust mask. The
vacuum cleaner must be approved for the ex-
traction of masonry dust.
Caution! Diamond cutting discs become very
hot during operation; do not touch them before
they have cooled down.
Never allow children to use the machine.
Bosch is only able to ensure perfect function-
ing of the machine if the original accessories
intended for it are used.
Information Structures
Slots in load carrying walls are subject to the
Standard DIN 1053, Part 1 or country-specific
regulations.
These regulations are to be observed under all
circumstances. Before beginning work, consult
the responsible structural engineer, architects or
the construction supervisor.
The permitted slot depth and width depends on
the slot length, wall thickness and the used build-
ing material.

Intended Use

With a firm support of the cutting guide, the ma-
chine is intended to cut or slot mainly mineral ma-
terials such as reinforced concrete, brickwork
and road surfaces without the use of water.
