4.3.2 Setting up and operating the microspeed® uni shaver
handpiece GD682
Note
Shaver handpiece GD682 can only be used with foot control GD671 and a
surgical suction device (e.g. GF200 or GF210).
The instruction menu allows changing motor type-specific settings (slow-
down and speed-up ramps and oscillation frequency, speed-up ramp for
Shaving mode), see chapter Instruction menu.
Parameter settings can only be changed if:
• a motor with motor cable GD673 is connected at the second motor
connection socket without being active, or
• a pistol handpiece GD684 is connected at the second motor connection
socket without being active, or
• a motor with motor cable GD672 is connected at the second motor
connection socket and the motor release switch is in its “OFF” position,
or
• only one shaver handpiece GD682 is connected at the control unit and
• a foot control device is connected to the control unit.
The following settings cannot be changed while shaver handpiece GD682
is running:
• Motor direction (of rotation)
• Motor speed range upper limit
• Operating mode
All settings will be saved on exit from the settings mode.
Operating modes
There are two types of blades for shaver handpiece GD682:
• Reamer blades
• Shaver blades
Control unit
1
recognizes whether the coupled blade is a reamer or a
shaver blade. The respective mode of operation (reaming or shaving) is
indicated on the display.
An acoustic signal is issued whenever a blade of a different type is
inserted, and the respective symbol is displayed in the appropriate motor
control field.
With a reamer blade coupled, the motor can be operated in right or left
rotation, but not in oscillating mode. The maximum speed is limited to
8,000 1/min. The symbol for the "Reaming" operating mode is displayed in
the control field.
With a shaver blade coupled, the motor can be operated in right or left
rotation as well as in oscillating mode. The maximum speed is limited to
5,000 1/min. The symbol for the "Shaving" operating mode is displayed in
the control field.
