Operating Instructions

To control the suction flow rate, move the suction port valve towards the front
of the handpiece to increase flow and move the suction port valve towards the
back of the handpiece to restrict or stop flow. To attain maximum performance
while resecting tissue or bone, the suction port valve must be in the fully open
position.
These shaver handpieces can be operated using a footswitch or the control
buttons on the handpiece. For the footswitch operating instructions, please refer
to the surgical console instruction manual.
For shaver handpiece operation using the buttons on the handpiece (D4240 and
D9824):
Press and release to turn the shaver handpiece on and off.
Controlling window indexing using the buttons: The following operation
applies only when the handpiece is NOT running. When the handpiece ON/
OFF button is pressed and held, the console beeps once and the blade window
starts to rotate (index) slowly at 6 rpm. When the window position of the blade
is found (generally window completely open or window completely shut),
release the ON/OFF button. The handpiece will return the blade window to this
location when it is stopped.
Controlling speed using the buttons: The following operation applies only when
the handpiece is NOT running. When the handpiece DIRECTION SELECT
button is held for 1.5 seconds, the console beeps twice. Then the handpiece
DIRECTION SELECT button changes to the Increase Speed button. The ON/
OFF button changes to the Decrease Speed button. This enables the surgeon to
change the handpiece operating speed from the sterile field. If no button is
pressed for 1.5 seconds, the console beeps twice and returns to normal button
functionality.
