CONTROLS
2.5.1 KNIFE BLOCK ADJUSTMENT
For large movements of the knife holder or
rapid advance (e.g. specimen trimming) first
raise the knife block clamp locking lever on
the right-hand side of the knife holder then
turn the knife carriage feed control on the
front of the microtome base. To turn clockwise
will move the knife towards the specimen and
to turn anticlockwise will move the knife away
from the specimen.
When set in the desired position lower the
knife block clamp lever to lock in position.
2.5.2 SECTION THICKNESS CONTROL
To select section thickness, set the thickness
control at zero and rotate anticlockwise until
desired thickness is level with the indicator.
To reset the section thickness at any time,
ensure that the thickness control is always
reset back to zero before selecting the new
section thickness.
NB:
If feed screws other than the standard
0.5 - 30µm are fitted, a conversion factor is
needed.
