in accordance with the manufacturerʼs
instructions.
Each time before using a grinding wheel, check it
carefully. Never use a grinding wheel which is
broken, cracked or damaged in any other way.
Make sure that the grinding tools are mounted in
accordance to the Manufactors instructions.
If backing layers are supplied with or stipulated
for the grinding wheels, make sure they are used.
Before beginning with your work, make sure that
the grinding wheel is correctly mounted and
secured. Allow the tool to run in a safe position
for 5 minutes in idle mode. Stop the tool
immediately if notable vibrations develop or if you
discover any defects. In this case, examine the
machine to find the cause of the trouble.
Never use the grinder without the supplied hood
guard.
Never use a separate reducer sleeve or adapter
to mount grinding wheels with too large a hole.
Make sure that no danger results from any
sparks produced during use, e.g. injury to
persons or ignition of flammable substances.
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 residual risk factors cannot be completely
eliminated. The following hazards may arise in
connection with the machineʼs 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
condition 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 machine 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
bonding, 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 grinding
wheels must be of identical size and format.
Backing layers between the clamping flange and
the grinding wheel must be made of elastic
materials, 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
transparent 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
grinding wheel is:
Ø 150 = 23.16 m/s
Calculation:
peripheral speed
m/s = d x 3,14 x n
60 x 1000
d = diameter of the grinding wheel in mm
n = motor rpm
Example:
m/s = 150 x 3,14 x 2950
60 x 1000
= 23.16 m/s
12. The maximum peripheral speed of the wet
grinding wheel is:
