Safety instructions for table-top grinding machines
a) Do not use damaged tool inserts. Check tool
attachments such as grinding discs for chip-
ping and cracks before each use. Once you
have checked and used the tool attachment,
ensure that you and all other persons in the vi-
cinity remain outside the plane of the rotating
tool attachment and allow the device to run for
1 min. at the maximum speed.
Damaged tool attachments usually break during
this test period.
b) The permissible rotational speed for tool at-
tachments must be at least as high as the max-
imum speed cited on the electric tool. Accesso-
ries that rotate faster than permitted can break and
fly off at high speed.
c) Never grind on the side surfaces of the grind-
ing disc. Grinding on the side surfaces can cause
the grinding disc to break and fall apart.
Special safety information
1. Always wear safety goggles, protective gloves and
ear-muffs while carrying out grinding, brushing
and cutting jobs.
2. Check that the rotating speed shown on the wheel
is equal to or higher than the rated speed of rota-
tion for the tool.
3. Make sure that the grinding wheel is of the correct
size for the grinder.
4. Grinding wheels must be handled and stored with
care in accordance with the manufacturer's in-
structions. 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 accord-
ance 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 posi-
tion 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 an-
yone 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 be-
come 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 plas-
tic 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, ide-
ally 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 elas-
tic 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 clear-
ance).
22. Grinding wheels are not allowed to be used with-
out 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
