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-

tool.
Tighten down tension nut with two-hole nut drive.
The grinding tools must run true. Do not use grind-

Check grinding tools before use. The grinding tool
must be correctly mounted and must rotate freely. Per-

orKing instructions
To achieve an optimum result, move tool uniformly back
and forth with light pressure. The electronic constant con-
trol maintains the speed nearly constant during idling and
work under load and assures a uniform result. Excessive
pressure lessens the working capability of the machine,
as well as the life of the tool. The machine is equipped
with an electronic control and integrated overload pro-
tection. If the machine is overloaded, the speed will drop
drastically. Immediately take the load off the machine and
allow to run for a short time without load.
