The declared vibration emission level repre-
sents the main applications of the tool. However
if the tool is used for different applications, with
different accessories or poorly maintained, the
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.

Mounting the Grinding Tools
(see figure A)
– Clean the grinder spindle 3 and all parts to
be mounted.
1 609 929 X18 | (9.8.10)
– Turn the grinder spindle 3 until the hole in
the grinder spindle 3 and the openings of the
housing are aligned. Insert the holding rod 8
through the hole of the grinder spindle 3.
– Loosen the clamping nut 2 with the open-end
spanner 9 (size 17 mm) by turning in anti-
clockwise direction.
– Insert the clamping shaft of the grinding tool
to the stop into the collet chuck 1.
– Tighten the clamping nut 2 with the open-
end spanner 9 (size 17 mm) by turning in
clockwise direction.
The grinding tools must run completely concen-
trically. Do not continue to use damaged grind-
ing tools that are out of balance. If the grinding
tools are out of balance they should be re-
placed. Treat with a whetstone (accessory) or
change.
Using a whetstone, any particular special shape
can be produced out of the basic forms of the
grinding accessory.
Do not tighten the collet chuck of the
clamping nut as long as no grinding acces-
sory is mounted. Otherwise, the collet chuck
can become damaged.

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.
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.
– 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.
Prevent dust accumulation at the work-
place. Dusts can easily ignite.
