Troubleshooting
After lengthy use unit does
not spray.
Unit is overheated. → Slots of
the unit should not be cov-
ered or blocked. Let cool
down the unit for a while.
The unit shows different
sound levels at different sites
of use.
The sound level varies ac-
cording 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.
Very seldom this error might
occur. It would not damage
the motor at all.
