Safety retractable handles GN 598.7
are suitable for
applications where the handle must not remain in the
operating position.
In order to bring the handle into the operating position, it
has to be pulled up 90° from its retracted position against
a torsion spring to a stop, and then it is pushed against
spring pressure into its hold position. By maintaining the
forward thrust on the handle, the handwheel can easily
be rotated.
When releasing the handle, the spring automatically re-
turns it back to the
retracted position.
Maximum heat resistance of phenolic plastic hand piece:
150°C (300°F). |
