6.7 Friction Clutch on the Coarse Advanced Drive Mechanism
On reaching the front and rear positions of the specimen feed, a friction clutch built into
the coarse advanced drive prevents the blocking of this coarse advanced drive. As soon
as an audible engagement is triggered by the coarse drive, the feeding operation of the
specimen stops. Upon rotation of the hand wheel of the coarse advanced drive in the
opposite direction, the feeding motion is restored.
If the feeding motion is not restored by this procedure, the hand wheel of the coarse
advanced drive mechanism must be pressed inwards against the casing. Only a short
forward or backward movement is needed to ultimately activate the feeding motion.
Important!
Avoid touching the specimen or the specimen holder containing the knife when
operating the hand wheel of the coarse advanced drive mechanism.
6.8 The Handwheel of the Coarse Advanced Drive Mechanism (11)
The hand wheel of the coarse advanced drive mechanism is integrated in the casing.
6.9 Collision Protection Device
On the specimen feed system reaching its forward terminal position, a
red mark is visible on the cylinder. From this mark there is a further
distance of adjustment of max. 2500 microns available. A second red
mark then becomes visible, and the cylinder must be rotated back by
means of the hand wheel of the coarse advanced drive (11), before
further cuts can be made.
Important!
As soon as the remaining distance of adjustment of 2500 microns is exceeded, the
preselected thickness of cut is disabled by the in-built collision protection device.
Any automatic adjustment by rotating the hand wheel is now inactivated.
6.9.1. Emergency shutdown
After pressing the emergency shutdown key the rotary microtome stops immediately.
After releasing the emergency shutdown key, it takes approx. sec until the rotary
microtome operates normal.
