3.2.1 f
itting of grinding tools
Clean backing flange, clamping nut and backing flange
surface of the grinding tool.
Place backing flange on the spindle with the longitudinal
groove down.
Fit the grinding tool. The raised centering rim of the back-
ing flange must engage exactly in the bore of the grinding
tool.
Tighten down tension nut with two-hole nut drive.
The grinding tools must run true. Do not use grind-
ing tools which have gotten out of round! Trial run!
Check grinding tools before use. The grinding tool
must be correctly mounted and must rotate freely. Per-
form a trial run a minimum over a period of 30 seconds
without load. Do not use grinding tools which are dam-
aged, which do not run true or which vibrate!

On failure of the compressed air release the valve
lever! To achieve an optimum result, move grin-
ding tool uniformly back and forth with light pres-
sure. Excessive pressure lessens the working capability
