Connecting the accessories
Combinations of accessories that are not mentioned in the present
instructions for use may only be employed if they are specifically intended
for the respective application, and if they do not compromise the perfor-
mance and safety characteristics of the products.

Coupling handpieces
Handpiece with Intra-coupling 20 and pneumatic motor 3:
►
Push the pneumatic motor 3 intra-coupling 20 into the micro-Line
handpiece until it rests against the end face of the motor and snaps in.
Detaching the handpiece
Handpiece with Intra-coupling 20 and pneumatic motor 3:
►
Press the release button 21 and pull the handpiece off.
Connecting the compressed-air supply
Danger of fire and explosion when operating
devices that run on oxygen!
►
DANGER Never operate the pneumatic motor with oxy-
gen!
►
Operate the pneumatic motor with compressed
air or nitrogen.
Operating pressures in excess of 10bar will damage
the pneumatic motor!
►
Set a flow pressure of between 6 and 10 bar.
CAUTION
Note
For operation, a compressed air supply of 6 bar to 10 bar (0.6 MPa to
1.0 MPa) is needed.
Operation with central gas supply as per DIN 13260 and EN 737 and
with low-pressure hose line systems for use with medical gases as per
DIN EN ISO 5359
4
®
The gas supply must provide clean, dry air and must be set as follows:
Nominal operating pressure (gauge pressure)
Maximum allowable operating pressure
Minimum operating pressure
Maximum allowable backup pressure in exit air con-
duit while motor is operating (with exit air recycling)
Minimum gas-supply delivery
Operation with compressed-gas cylinders according to DIN EN
ISO 11117
The following conditions must be met:
■
Compressed air or nitrogen is used
■
An adequate stock of full gas cylinders is in place
■
Cylinder pressure of appr. 150 to 200 bar must be reduced with a pres-
sure reducer (e.g. GA099) to a nominal operating pressure of 8 bar
►
Operating pressure must be read from the scale on the device and set
with the T-screw.
When operating the motor with compressed gas cylinders, the exhaust air
is not removed from the operative field, but instead emerges from the end
of the hose, away from the operative site.
Connecting the motor to the compressed air supply
Note
Long hoses may cause a backup of exhaust air and thus a loss of perfor-
mance of the pneumatic motor.
►
Use hose lines that are as short as possible.
►
Make certain that the hose lines are not kinked or crushed.
►
Use a compatible extension hose if necessary.
Connecting the motor to the foot control
►
Make certain the ring for selecting the direction of rotation 22 on the
pneumatic motor is in "0" position.
►
Pull back the sleeve 5 on the motor hose 7 and connect the motor hose
with the fast-lock coupling 4 on the motor 3.
►
Insert the plug 8 of the motor hose 7 into the foot control.
Connecting the foot control to the compressed air supply
►
Depending on the compressed air system, choose the appropriate hose
for the Aesculap Dräger system, DIN system or Schrader system.
►
Pull back the sleeve 12 on the hose 10 and connect the hose with the
fast-lock coupling 13 on the foot control.
►
Insert the plug 8/14/15 of the hose 10 into the compressed air supply
can 16/17/19.
