Notes
– Too high working pressure could cause the
motor to stall.
– Keep pressing the slitting control switch ( )
to ensure a constant slitt ing depth.
– Move the tool slightly back and forth when
encountering hard materials.
– Prefer downwards direction for vertical slit-
ting.
– Use the original Hilti DC-D125SE diamond
discs to achieve high slitting performance.
– Use a TDA-VC40 industrial vacuum cleaner,
or one with a suction capacity of at least
2100 l/min.
– Shake off dust every 10–15 minutes of ope-
ration.
– Use a dressing stone (flat or round) to increa-
se cutting performance.
– Don't press too hard to improve cutting per-
formance. This can overheat and destroy
diamond discs.

Care and maintenance

CAUTION
Disconnect the supply cord plug from the
power outlet.
Care of the power tool
CAUTION
Keep the power tool, especially its grip sur-
faces, clean and free from oil and grease.
Do not use cleaning agents which contain
silicone.
The outer casing of the power tool is made from
impact-resistant plastic. Sections of the grip
are made from a synthetic rubber material.
Never operate the power tool when the venti-
lation slots are blocked. Clean the ventilation
slots carefully using a dry brush. Do not permit
foreign objects to enter the interior of the power
tool. Clean the outside of the power tool at regu-
lar intervals with a slightly damp cloth. Do not
use a spray, steam pressure cleaning equip-
ment or running water for cleaning. This may
negatively affect the electrical safety of the
power tool.
Changing the carbon
brushes
Repairs to the electrical section may only
be carried out by an electrician/electrical
specialist.
Whenever brushes need to be changed, they
will automatically switch off the machine.
Only use original carbon brushes.
Disposal
Most of the materials from which
Hilti power tools are manufactured
can be recycled. The materials must
be correctly separated before they
can be recycled. In many countries, Hilti has
already made arrangements for taking back
your old electric tools for recycling. Please
ask your Hilti customer service department
or Hilti sales representative for further infor-
mation.
Only for EU countries
Disposal of electric tools together with house-
hold waste is not permissible!
In observance of European Directive on waste
electrical and electronic equipment and its
implementation in accordance with nation-
al law, electric tools that have reached the
end of their life must be collected separate-
