ools
Use only tools and adapters recommended by the
manufacturer. Observe the tool manufacturers in-
structions! Use only grinding tools and chucks
whose admissible maximum speed is equal to or higher
than the no-load speed of the machine. Use only clean
tools!
3.2.1 c /
hAnging fitting the tool
Hold spindle by wrench flats with open end wrench and
release/tighten down collet chuck with open end wrench.
The grinding tool 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 used grinding tools which are dam-
aged, which do not run true or which vibrate!
3.3 w
orKing instructions
To run the machine down release the valve lever!
On failure of the compressed air release the valve
lever! Place or fasten the tool securely on the
working surface. To achieve an optimum grinding result,
move grinding tool uniformly back and forth with light
pressure. Excessive pressure lessens the working capa-
bility of the machine, as well as the life of the grinding tool.

periodically and after each maintenance. Even if
the machine still operates perfectly, the motor
should be removed, cleaned and the four slides checked
for wear by a specialist after approx. 300 to 400 operating
hours. The lubricant in the gear head (Isoflex NBU 15)
should be replaced (do not wash out).
