Note
The pistol handpiece can be locked against inadvertent actuation by gently
pressing and turning the upper trigger by 90°.
The pistol handpiece cannot be used with foot control.
Pistol handpiece GD684 is fitted with the Aesculap mini-Line coupling
system.
A protective sleeve is supplied with the handpiece. This sleeve serves to
protect against injury and damage when inserting Kirschner wires.
There are two operating modes of pistol handpiece GD684:
• Standard operation
• Oscillating or tapping mode
If control unit
1
recognizes a pistol handpiece GD684 connected, the
pistol handpiece will operate in the Standard mode (factory setting). The
device parameter settings (speed range upper limit, delivery rate, pump
status) can be changed only via the touch control field of control unit
1
.
Oscillating or tapping mode can be selected via the Instruction menu. The
symbol for “Oscillating or tapping mode” is displayed in the respective
motor control field. Oscillating or tapping mode is activated though the
upper trigger. An acoustic notification signal is sounded and “Oscillating
or tapping mode active” flashes in the respective motor control field. In
this mode of operation, the speed range upper limit cannot be changed via
the touch control field on control unit
1
.
The oscillating or tapping mode can be deactivated again by pressing the
upper trigger. After each power-up of the control unit and connection of
the pistol handpiece, oscillating or tapping mode is always deactivated
and needs to be activated anew via the pistol handpice. The preselected
setting in the Instruction menu is saved and remains in memory even
through subsequent system restarts.
Standard operation
:
Right and left rotation mode (when in left-rotation mode, control unit
1
issues an acoustic signal).
Motor direction switch/trigger for left rotation
34
, see Fig. 7:
• Pressing lower trigger
35
while holding down upper trigger
34
makes
the pistol handpiece operate in left-rotation mode.
• The motor direction is changed by pressing trigger
34
with trigger
35
already actuated.
Motor speed control trigger
35
:
• Actuator for motor speed setting (motor speed proportional to
actuator travel).
• If only trigger
35
is pressed, the pistol operates in right rotation mode.
Oscillating or tapping mode
:
Activating or deactivating the operating mode, see Fig. 7:
• This mode of operation is activated (and deactivated) by pressing and
holding upper trigger
34
for three seconds.
Working in “Oscillating or tapping mode”:
• The pistol handpiece is operated in tapping mode by pressing lower
trigger
35
within the first half of the total trigger travel. The motor
speed is proportional to the actual trigger travel.
Tapping mode means: Clockwise rotation by a certain angle (forward step)
followed by counterclockwise rotation (backward step) by a smaller angle.
• The pistol handpiece is operated in oscillating mode by pressing lower
trigger
35
within the second half of the total trigger travel. The motor
speed is proportional to the actual trigger travel.
Oscillating mode means: Clockwise rotation by a certain angle followed by
counterclockwise rotation by the same angle.
The pistol handpiece is operated in left-rotation mode by pressing lower
trigger
35
at the same time as upper trigger
34
.
