•
The electric tool must never be used without
the guard hood supplied with it.
•
Never use separate reducer sleeves or adap-
ters to make grinding wheels with larger holes
fit on the machine.
•
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.
•
Always wear safety goggles and ear-muffs;
use other personal safety equipment such as
gloves, an apron and a helmet if necessary.
•
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.
•
Do not use coolant or the like.
Special safety information
Danger!
1. 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 fi t 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 pro-
gress.
2. Use only grinding wheels which are marked
with details of the manufacturer, the type of
bonding agent used, dimensions and the per-
missible RPM.
3. Grinding wheels must be stored in a dry
place, ideally at a constant temperature.
4. Use only the clamping fl anges supplied with
the equipment to mount the grinding wheels.
5. Use only clamping fl anges of identical size
and identical shape to mount the grinding
wheels. The intermediate layers between the
clamping fl ange and the grinding wheel must
be comprised of elastic materials, e.g. rubber,
soft cardboard, etc.
6. Never enlarge a grinding wheel's mounting
hole by subsequent drilling.
7. The workpiece supports and the top adjus-
table safety guards must always be moved as
close as possible to the grinding wheel (max.
2 mm clearance).
8. Grinding wheels are not allowed to be used
without the safety device. The following clea-
rances must not be exceeded:
Anl_SA_TC_BG_150_Bivolt_SPK8.indb 26 Anl_SA_TC_BG_150_Bivolt_SPK8.indb 26
GB
- Workpiece support/grinding wheel: max. 2
mm
- Safety guard/grinding wheel: max. 2 mm
9. The guard holder, workpiece support and
transparent guard must be fi tted before the
double grinder is used.
10. The power plug must be pulled out before
changing the grinding wheel.
11. The max. circumferential speed of the dry
grinding wheel is:
m/s = (d x 3.14 x n) / (60 x 1000)
d = diameter of the grinding wheel in mm
n = motor revolutions per minute
12. Max. permitted motor housing temperature:
80°C
13. Before starting work, fi rmly screw the grinder
to the workbench etc. using the 4 mounting
holes in the base plate.
14. Adjust the spark defl ector periodically in order
to compensate the wear of the wheel. Please
note that the distance between the spark de-
fl ector and the wheel is to be kept as small as
possible and should in no case exceed 2mm.
15. The grinding wheel must be replaced at
the latest when the spark defl ector and the
workpiece support can no longer be set a
maximum distance of 2mm from the grinding
wheel.
Keep this safety information in a safe place.
