4.7 Connecting/Disconnecting the spray nozzle

Risk of spray nozzle breakage caused by excessive
or frequent bending!
Handle the spray nozzle with appropriate care.
WARNING
Note
A spray nozzle can be connected at the dura protector or the holding sleeve
for the purpose of cooling the tools and, especially, to avoid necroses.
If the connection of the spray nozzle at the dura protector or the holding
sleeve is unstable, vibrations can cause the tip of the spray nozzle to touch
the rotating tool, leading to metal chipping.

4.7.1 Connecting the spray nozzle

Push spray nozzle 25 from the front end onto dura protector foot 8 or
holding sleeve 20.
Hold tube olive 26 and push irrigation tube 27 over tube olive 26.
If necessary, align the tip of spray nozzle 25 towards the tool.
Set the irrigation flow at the control unit, as described in the
instructions for use of HiLAN irrigation pump GA530 or microspeed®
uni control unit with cooling unit GD670.

4.7.2 Disconnecting the spray nozzle

Pull off irrigation tube 27 from tube olive 26.
Pull off spray nozzle 25 from dura protection foot 8 or holding
sleeve 20.

4.8 Function checks

Prior to each use, test-run the craniotome handpiece with a tool
coupled and a dura protector or depth stop/ holding sleeve mounted.
Ensure that the craniotome handpiece, the dura protector/attachment
and the tool are in proper condition.
Ensure that the tool and the dura protector/attachment are coupled
correctly.
Ensure that the craniotome handpiece with a tool coupled runs quietly
and vibration-free.
Prior to each use, check and ensure that the bridge at the guard bracket
of the dura protector is straight; also ensure that the guard bracket
does not touch the craniotome reamer.
Ensure that the front face of craniotome reamer C is in position
between stop face A and base B of dura protector foot 8.
Note
The front face of craniotome reamer
could lead to heat-up and metal abrasion; it also must not be positioned
above stop face A , since this would leave a bone chip
