vibration emission may differ. This may signifi-
cantly increase the exposure level over the total
working 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 to-
tal 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.

Certification
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
External Dust Extraction (see figure A)
Attach a vacuum hose 7 onto the outlet piece 3.
Connect the vacuum hose 7 with a vacuum
cleaner. An overview for connecting to various
vacuum cleaners can be found at the beginning
of these operating instructions.
The vacuum cleaner must be suitable for the ma-
terial being worked.
When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special
vacuum cleaner.
Replacing the Sanding Sheet
(see figure B)
When attaching a new sanding sheet, remove
any dust or debris from the sanding plate 5 (e. g.
with a brush).
To ensure optimum dust extraction, pay atten-
tion that the punched holes in the sanding sheet
match with the holes in the sanding plate.
The sanding plate 5 is fitted with Velcro backing
for quick and easy fastening of sanding sheets
with Velcro adhesion.
Before attaching the sanding sheet 4, free the
Velcro backing of the sanding plate 5 from any
debris by tapping against it in order to enable
optimum adhesion.
Position the sanding sheet 4 flush alongside one
edge of the sanding plate 5, then lay the sanding
sheet onto the sanding plate and press firmly.
