D.1.6 COVER SCREW
For implant systems requiring placement of a cover screw, it is strongly recommended to use a
special system access key which is available as an accessory - see Chapter A.2 of this manual.
The cover screw system access key provides low speed and reduced torque for cover screw
placement.
1.
Insert the system key into the system key port and note the factory programmed parameters on
the display i.e. speed = 25 RPM, direction = forward and torque = 25 Ncm. Irrigation is switched
OFF.
2.
Start the handmotor by stepping the motor start switch on the foot control and hold down until
the handmotor is about to stall. The cover screw has now been tightened to the pre-set torque
of about 25 Ncm provided that the contra-angle is in good mechanical condition.
3.
The direction of rotation can be reversed by stepping on the select switch on the foot control.
An alarm signal will sound as soon as the handmotor is started in reverse.
D.2 INDIVIDUALIZING IMPLANT SYSTEM PARAMETERS
The preceding section D.1 explained operation and use of system specific parameters as pre-
programmed by the factory and as recommended by respective implant manufacturers.
It is, however, possible to manually alter or individualize parameter values.
1.
Insert the implant system access key in question into the system key port - see Fig. 9 - and enter
the programme step in question by operating the select switch on the foot control - see Fig. 10.
