and foot pedal[Fig. 13].
6.2 The motor speed can be controlled by
speed control knob ② within the limit of
0~40,000RPM[Fig. 13].
6.3 The operation of turbo switch ③ is
possible only at the motor speed of
40,000RPM, therefore, which is accelerated
to 50,000RPM[Fig. 13].
6.4 To control the motor speed by means of
knee control panel ⑧ and foot pedal ⑮, it
is required to press run switch ⑤ to start
the motor. Beeps are made by pressing auto
cruise switch ⑤ for 2 seconds and then the

the uniform speed even after releasing knee
control panel ⑧ and foot pedal ⑮. The
auto cruise mode can be released by
pressing either knee control panel ⑧ or
foot pedal ⑮ again, or by pushing auto
cruise switch ⑤ [Fig. 13].

control panel ⑧ and foot pedal ⑮ within

selector switch ④ is off, the motor is
running counterclockwise[Fig. 13].
6.8 Test bur can be replaced by turning chuck
handle clockwise. After replacing the test
bur or a polishing point, the chuck handle
