BrAsiVes
Speed rating on the abrasive is equal to or greater
than the speed adjusted on the machine.
Exclusively abrasives from the SUHNER catalog
are to be used.
Threat and store abrasives appropriately.
Damaged abrasives discs may not be used.
Always switch off the machine before changing the tool
or abrasive.

nitiAtion Afety nstructions
During operation avoid sharp bendings of the flex-
ible shaft. Excessively small bend radius will result
in premature wear. Strong whipping movements
and convulsions of the flexible shaft are signs of overload-
ing. As countermeasures use smaller tool or increase ro-
tational speed. However, this only in stict observation of
the instructions on the maximum allowed circumferential
speed of the respective tool.

AintenAnce of the mAchine
Dry the machine and keep clean in stor-
age.
Keep cooling air openings unclogged.
Regularly check connection line. Have defective lines or
connectors replaced. Have repairs done by a technician
only.
Do not spray down with water. Clean surface with lightly
moistened rags.
In case the machine is operated in one gear position only
one must at least once a week switch through all posi-
tions for a brief period in order to redistribute the grease
for l ong gear service life (run without flexibel shaft and
handpiece).
