Adjusting the speed
Using the two " Motor Speed " +/– keys (14), the
recalled speed can be manually increased or decreased
and then indicated as the maximum speed on the dis-
play.
Adjustment is possible in increments of:
10 rpm
– between 90 and 400 rpm
200 rpm – between 400 and 5,000 rpm and
1,000 rpm – between 5,000 and 40,000 rpm
The speed last set with the +/– keys (14) is preserved
even after the unit is switched OFF and back ON again
if the foot switch was
previously actuated at least
once .
ATTENTION
The speed can be changed even while the motor is run-
ning.
The instrument must not be in the patient’s mouth when a
speed adjustment is performed.
Reversal of rotation
ATTENTION
From your carbide burs, you may be used to clockwise
rotation only.
Please note that your new electric motor can also be
operated
counterclockwise .
Prior to switching to counterclockwise rotation, make
sure that the contra-angle handpiece and the respective
inserts used can be operated counterclockwise
(Caution: Contra-angle handpiece for prophylaxis must
be operated clockwise only!).
To switch the electric motor to counterclockwise rotation,
press the "
Reverse " key (22).
Counterclockwise rotation is signaled by the flashing
CCW arrow on the display.
Changeover to counterclockwise rotation with the
"
Reverse " key is also possible while the motor is run-
ning.
In this case, the motor gradually runs down in the
selected direction of rotation before starting up again
in the other direction.
After the unit is switched OFF and back ON again, the
motor is automatically reset to clockwise rotation and the
flashing arrow disappears on the display.
ATTENTION
The instrument must not be in the patient’s mouth when a
speed adjustment is performed.
Prior to each motor start, please check to make sure the
motor has not inadvertently been set to counterclockwise
rotation!
