• Always wear safety goggles and ear-protectors.
Use other personal safety items such as gloves, an
apron and a helmet wherever necessary.
• Please note that the workpiece becomes hot during
use.
Caution! Risk of burns!
Allow the workpiece to cool. Some materials
become glowing hot when subjected to grinding.
On lengthy jobs, interrupt your work and allow the
workpiece to cool.
• Use no coolant or the like. The wet-and-dry grinder
is a multi-function tool for the rough and precision
grinding of metals, plastics and other materials
using a selection of grinding wheels. The machine
must only be used for its intended purpose!
• Even if the machine is used as intended, certain re-
sidual risk factors cannot be completely eliminated.
The following hazards may arise in connection with
the machine's construction and layout:
• Contact with the grinding wheel where it is not
covered.
• Catapulting of parts from damaged grinding wheels.
• Catapulting of workpieces and parts of workpieces
from the machine.
• Damage to hearing if ear-muffs are not used as
necessary.
Special safety instructions
1. Each time before you begin to work with the
grinding machine, carry out an acoustic test on its
grinding wheel (if a grinding wheel is in good con-
dition it will produce a clear tone when tapped,
e.g. with a plastic hammer). It is also important to
perform this test when fitting new grinding wheels
(risk of damage in transit). Always have the ma-
chine run in idle mode for a test period of at least
5 minutes. Leave the danger zone for this period.
2. Use only grinding wheels which are marked with
data specifying the manufacturer, type of bond-
ing, dimensions and permissible rpm.
3. Keep grinding wheels in a dry place where the
temperature is as constant as possible.
4. Use only the supplied clamping flanges to mount
the grinding wheels.
5. The clamping flanges used to mount the grind-
ing wheels must be of identical size and format.
Backing layers between the clamping flange and
the grinding wheel must be made of elastic mate-
rials, e.g. rubber, soft board, etc.
6. It is prohibited to enlarge the mounting hole in a
grinding wheel by re-drilling.
7. The workpiece supports and the adjustable upper
guards must always be positioned as close as
possible to the grinding wheel (max. gap 3 mm).
8. Never use a grinding wheel without a safety
guard. Make sure that the following distances are
not exceeded:
• workpiece support / grinding wheel: max. 2
mm
• safety guard / grinding wheel: max. 2 mm
9. The guard holder, workpiece support and trans-
parent guard must all be fitted before you use the
double grinder.
10. Always pull out the power plug before changing a
grinding wheel.

11. The maximum peripheral speed of the dry grind-
ing wheel is:
Ø 150 = 23 m/s
12. The maximum peripheral speed of the wet grind-
ing wheel is:
Ø 150 = 1,3 m/s
13. Maximum permissible motor housing tempera-
ture: 80°C
14. Fill the black water tank of the fine grinding wheel
with water up to the shaft axle.
15. Before starting work firmly screw the grinder to
the workbench etc. using the 4 mounting holes in
the base plate.
16. 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.
17. The grinding wheel must be replaced at the latest
when the spark deflector and the workpiece sup-
port can no longer be set a maximum distance of
2 mm from the grinding wheel.
18. Use only grinding wheels that are recommended
by the manufacturer which are marked with a
peripheral speed that is equal or greater than the
speed shown on the rating plate of the electric
tool
19. When the grinding wheels are blocked due to
abnormal feed force or a jammed work piece dur-
ing grinding, turn the machine off and disconnect
it from power supply. Remove the work piece and
ensure that both grinding wheels runs free. Turn
the machine on and start new grinding operation
with reduced feed force.
Warning! This electric tool generates an electro-
magnetic field during operation. This field can impair
active or passive medical implants under certain con-
ditions. In order to prevent the risk of serious or dead-
ly injuries, we recommend that persons with medical
implants consult with their physician and the manu-
facturer of the medical implant prior to operating the
electric tool.
