bur/tool itself can be tested with
the Bur Shaft Tester (art. 4990) to
see if it is bent.

tool
was exceeded, which
caused a stronger vibration.

The unit shows different sound
levels at different sites of use.
The sound level varies according
to the surroundings of the unit. If
you set up the unit directly in front
of a wall, the sound is reflected
stronger, as if it would, while
standing further away from a
wall.
The motor of the handpiece
stutters
(e.g. 1 sec.) while
switching it on.

After 5 min running, this effect will
disappear.

of the spray, turn the spray
