1. 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 2 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 Eye shield 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:
m/s=(d x 3,14 x n) / (60 x 1000)
d = diameter of the grinding wheel in mm
n = motor rpm
12. Maximum permissible motor housing temperature: 80°C
13. Before starting work firmly screw the grinder to the workbench etc. using the 4 mounting
holes in the base plate.
14. Adjust the Eye shield mount periodically in order to compensate the wear of the wheel.
Please note that the distance between the Eye shield mount and the wheel is to be kept as
small as possible and should in no case exceed 2 mm.
15. The grinding wheel must be replaced at the latest when the Eye Shield mount (3) and the
workpiece support (7) can no longer be set a maximum distance of 2 mm from the
grinding wheel.
