The vibration emission level given in this information sheet
has been measured in accordance with a standardised test
given in EN 60745 and may be used to compare one tool with
another. It may be used for a preliminary assessment of expo-
sure.
The declared vibration emission level represents the main ap-
plications 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 significantly in-
crease the exposure level over the total working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total working pe-
riod.
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 pat-
terns.

Assembly
Before any work on the machine itself, pull the mains plug.
Mounting the Grinding Tools (see figure A)
– Clean the grinder spindle 3 and all parts to be mounted.
– Hold the grinder spindle 3 on the spanner surfaces with the
open-end spanner 8 (size 17 mm).
– Loosen the clamping nut 2 with the open-end spanner 8
(size 17 mm) by turning in anticlockwise direction.
– Insert the clamping shaft of the grinding tool to the stop in-
to the collet chuck 1.
– Tighten the clamping nut 2 with the open-end spanner 8
(size 17 mm) by turning in clockwise direction.
The grinding tools must run completely concentrically. Do not
continue to use damaged grinding tools that are out of bal-
ance. 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 pro-
duced out of the basic forms of the grinding accessory.
Do not tighten the collet chuck of the clamping nut as
long as no grinding accessory is mounted. Otherwise,
the collet chuck can become damaged.
