and is in compliance with local
regulations.
c) If you are in doubt about the effective-
ness of the power outlet’s earth/ground
connection, have it checked by a quali-
fied specialist.
d) Avoid body contact with earthed or
grounded surfaces such as pipes,
radiators, ranges and refrigerators.
There is an increased risk of electric shock
if your body is earthed or grounded.
e) Do not expose appliances to rain or wet
conditions. Water entering an appliance
will increase the risk of electric shock.
f) Check the appliance’s supply cord at
regular intervals and have it replaced at
a Hilti service center if damage is found.

Before using the appliance to pick up dry dust,
especially dust from mineral materials, always
check to ensure that the correct dust bag (Hilti
accessory) is fitted in the container. The mate-
rial collected can then be disposed of cleanly
and easily.
CAUTION
The material collected must be disposed of
in accordance with the applicable regula-
tions.
CAUTION
Never use the appliance without a filter ele-
ment.
CAUTION
When fitting the top section of the vacuum
cleaner, take care to avoid pinching your
fingers or damaging the supply cord.
Check to ensure that the filter element is dry.
A damp filter element will quickly become
clogged when dry dust is picked up with the
appliance. Accordingly, before being used for
picking up dry dust, the filter element should
be rinsed and allowed to dry or replaced with
another dry filter element.

8 Care and maintenance
8.1 Automatic filter element cleaning
NOTE
Do not attempt to clean the filter element by
knocking it against a hard object and do not
use pointed instruments. This will reduce the
life of the filter element.
NOTE
Do not use compressed air to clean the fil-
ter element. This may cause tears in the filter
material.
NOTE
The condition of the filter will deteriorate with
use. It should be replaced at least every 6
months and more frequently if the appliance is
subject to heavy use.
The appliance is equipped with a filter clean-
ing system which removes most of the dust
adhering to the filter element.
The filter element is cleaned automatically by a
blast of air (a pulsating noise is heard).
NOTE

10 Disposal
Most of the materials from which Hilti power tools or appliances 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 power tools or appliances for recycling.
Ask Hilti customer service or your Hilti representative for further information.
Disposing of drilling slurry
Disposing of drilling slurry directly into rivers, lakes or the sewerage system without suitable
pretreatment presents environmental problems. Ask the local public authorities for information
about current regulations. We recommend the following pretreatment:
1. Collect the drilling slurry (for example, using a wet-type vacuum cleaner).
2. Allow the drilling slurry to settle and dispose of the solid material at a construction waste
disposal site (the addition of a flocculent may accelerate the separation process).
3. The remaining water (alkaline, pH value greater than 7) must be neutralized by the addition of
an acidic neutralizing agent or diluted with a large volume of water before it is allowed to flow
into the sewerage system.
Disposal of drilling dust
The drilling dust collected must be disposed of in accordance with the applicable national
regulations.
