ent accessories or poorly maintained, the vibra-
tion emission may differ. This may significantly
increase the exposure level over the total work-
ing period.
An estimation of the level of exposure to vibra-
tion should also take into account the times
when the tool is switched off or when it is run-
ning but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total
working period.
Identify additional safety measures to protect the
operator from the effects of vibration such as:
maintain the tool and the accessories, keep the
hands warm, organisation of work patterns.

Dust/Chip Extraction
Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
1 609 929 N25 | (5.12.07)
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in con-
nection with wood-treatment additives (chro-
mate, wood preservative). Materials contain-
ing asbestos may only be worked by
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the working
place.
– It is recommended to wear a P2 filter-class
respirator.
Observe the relevant regulations in your coun-
try for the materials to be worked.
Integrated Dust Extraction with Dust Box
(see figure D1 — D4)
Attach the dust box 1 onto the extraction outlet
8 until it latches.
To empty the dust box 1, press the latching
levers 9 on the side of the dust box ( ). Pull off
the dust box toward the bottom ( ).
Before opening the dust box 1, it is recommend-
ed to loosen the dust from the filter element by
gently striking it against a firm support (as shown
in the figure).
Grasp the dust box 1 by the recessed grip, fold
the filter element 10 upward and empty the dust
box. Clean the thin plates of the filter element 10
with a soft brush.
External Dust Extraction (see figure E)
Slide the extraction adapter 11 onto the outlet
piece 8. Ensure that the latching levers of the ex-
traction adapter engage. The extraction
adapter 11 accepts a vacuum hose with a diame-
ter of 19 mm.
An overview for connecting to different vacuum
cleaners can be found at the end of these operat-
ing instructions.
For removal of the extraction adapter 11, press
the latching levers together at the rear and pull
the extraction adapter off.
The vacuum cleaner must be suitable for the ma-
terial being worked.
When vacuuming dry dust that is especially detri-
mental to health or carcinogenic, use a special
vacuum cleaner.
