4. Grinding wheels must be handled and stored
with care in accordance with the manufacturer's
instructions. Examine the grinding wheel each
time before using it. Never use grinding wheels
which have parts broken off or are cracked or in
any other way damaged.
5. Be sure to use only grinding wheels and brushes
which are marked with a speed at least as high
as the speed indicated on the rating plate of the
electric tool.
6. Check that grinding wheels are fitted in
accordance with the manufacturer's instructions.
7. Make sure that intermediate layers are used if they
are supplied with and required for the grinding
wheel.
8. Make sure that the grinding disk is correctly fitted
and secured before you start to use the tool.
Allow the machine to run without load and in a
safe position for 5 minutes. Stop the machine
immediately if severe vibrations arise or any other
defects are noticed. If this should be the case,
examine the machine to find the cause.
9. The electric tool must never be used without the
guard hood supplied with it.
10. Never use separate reducer sleeves or adapters
to make grinding wheels with larger holes fit on
the machine.
11. Take precautions to ensure that flying sparks
do not cause any danger, e.g. that they do not
hit anyone or cause inflammable substances to
ignite.
12. Always wear safety goggles and ear-muffs; use
other personal safety equipment such as gloves,
an apron and a helmet if necessary.
13. The workpiece becomes hot during grinding.
Important! Risk of burns!
Let the workpiece cool down. The material may
become glowing hot during the grinding. On longer
jobs, allow the workpiece to cool down occasionally.
14. Do not use coolant or the like.
15. Before you use the grinder, carry out a ring test
on the grinding wheels (perfect grinding wheels
emit a clear tone when hit lightly with e.g. a plastic
hammer). This also applies when you fit new
grinding wheels (damage in transit). It is essential
to subject the machine to an unloaded test run of
at least 5 minutes. Leave the danger zone while
the test is in progress.
16. Use only grinding wheels which are marked with
details of the manufacturer, the type of bonding
agent used, dimensions and the permissible
RPM.
17. Grinding wheels must be stored in a dry place,
ideally at a constant temperature.
18. Use only the clamping flanges supplied with the
equipment to mount the grinding wheels.

19. Use only clamping flanges of identical size and
identical shape to mount the grinding wheels. The
intermediate layers between the clamping flange
and the grinding wheel must be comprised of
elastic materials, e.g. rubber, soft cardboard, etc.
20. Never enlarge a grinding wheels' mounting hole
by subsequent drilling.
21. The workpiece supports and the top adjustable
safety guards must always be moved as close
as possible to the grinding wheel (max. 2 mm
clearance).
22. Grinding wheels are not allowed to be used without
the safety device. The following clearances must
not be exceeded:
23. Workpiece support/grinding wheel: max. 2 mm
24. Safety guard/grinding wheel: max. 2 mm
25. The guard holder, workpiece support and
transparent guard must be fitted before the double
grinder is used.
26. The power plug must be pulled out before
changing the grinding wheel.
27. The max. circumferential speed of the dry grinding
wheel is: 23 m/s m/s = (d x 3.14 x n) / (60 x 1000)
d = diameter of the grinding wheel in mm
n = motor revolutions per minute
28. Max. permitted motor housing temperature: 80°C
29. Before starting work, firmly screw the grinder to
the workbench by using the 4 mounting points on
the base plate.
30. Adjust the spark deflector periodically in order to
compensate the wear of the wheel. Please note
that the distance between the spark deflector and
the wheel is to be kept as small as possible and
should in no case exceed 2 mm.
31. The grinding wheel must be replaced at the latest
when the spark deflector and the workpiece
support can no longer be set a maximum distance
of 2 mm from the grinding wheel.
Residual risks
Even if you use this electric power tool in accord-
ance with instructions, certain residual risks
cannot be ruled out. The following hazards may
arise in connection with the equipment's con-
struction and layout:
• Lung damage if no suitable protective dust mask
is used.
• Damage to hearing if no suitable ear protection is
used.
• Health damage caused by hand-arm vibrations if
the equipment is used over a prolonged period or is
not properly guided and maintained.
Keep this safety information in a safe place.
