10. Disposal
Return waste material for recycling
Most of the materials from which Hilti tools or machines 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
machines or tools for recycling. Please ask your Hilti customer service department or
Hilti sales representative for further information.
Disposal of drilling slurry
With regard to environmental aspects, allowing drilling slurry to flow directly into
rivers, lakes or the sewerage system without suitable pre-treatment is problematical.
Ask the local authorities for information about applicable regulations.
We recommend the following pre-treatment:
Collect the drilling slurry (e.g. use a wet-type industrial vacuum cleaner).
Allow the slurry to settle and dispose of the solid material at a construction waste
disposal site (the addition of a flocculent may accelerate the settling process).
Water from the drilling slurry (alkaline, ph value > 7) should be neutralized by adding
an acidic neutralizing agent or large quantity of water before it is allowed to flow into
the sewerage system.
Only for EU countries
Do not dispose of electric tools together with household waste material!
In observance of European Directive 2002/96/EC on waste electrical and
electronic equipment and its implementation in accordance with national
law, electric tools that have reached the end of their life must be
collected separately and returned to an environmentally compatible
recycling facility.

basplate, the vacuum indicator (7)
must remain within the green area.
2 Carriage
■ The guide rollers require no mainte-
nance.
■ Keep the motor unit mounting sur-
face clean.
■ If movement is too easy, the guide
rollers should be adjusted by a
trained specialist.
3 Rails
■ Keep the rails clean
■ Internal tapers must be kept clean
and lubricated
4 Baseplate
■ With the exception of the seals, the
baseplates require no maintenance.
1. Check that the motor is switched
off.
2. Connect the plug to the mains
supply.
3. Press the ON button. The lamp
must light!
4. Press the TEST button. The lamp
must extinguish!
5. Press the ON button again before
beginning operation.
In the case of a malfunction (test
failed), the unit must be checked by
an electrical specialist before work
with the equipment continues!
Tips
■ Reduce feed pressure and tighten
carriage locking device slightly when
starting holes in order to avoid vibra-
tion.
■ If steel reinforcement is contacted,
select lower drilling speed and
reduce water flow.
(Obtain permission from authorised
person before cutting through steel
reinforcement.)
■ The diamond segments can beco-
me polished (reduced cutting per-
formance) if drilling feed pressure is
too low.
■ Inadequate water flow will cause
the core bit to overheat, resulting in
permanent damage.

9.2 Wearing parts

■ Seals for the DD-BA-3 and DD-
BAV-4 vacuum baseplates
■ Sealing discs for the DD-WC-S
water collector
■ Sealing ring for the water collector
