Check the fusing (fuse) of your electrical supply.
3.8
Operation
Before you start grinding, check that the workpiece is free of oil, grease and paint residues
to prevent smudging or soiling of the grinding wheels.
Check the condition of the grinding wheels. If the grinding wheels are dirty or muddied, they
must be roughened or replaced.
If necessary, grind the workpiece with the coarse grinding wheel first, before using the fine
grinding wheel.
The workpiece support can be adjusted for certain grinding operations. Loosen the clamping
screw to adjust the workpiece support.
Note that this adjustment results in a reduced potential load absorption of the workpiece
support.
The distance between the grinding wheel and workpiece support must be as low as possi-
ble.
Only put slight pressure on the workpiece.
Check the state of the grinding wheel. If it is dirty, it must be scraped clean or replaced.
Grinding wheels must be disposed of in an environmentally friendly manner.
