Do not drag the anti-roll plate downwards across the edge of the blade as this will result in
possible damage to both the anti-roll plate and the blade.
Your anti-roll plate may vary from the design shown, but the set-up procedure remains the
same. Please refer to section 3.6, A Problem Solving Guide, for further assistance.

Common MICROTOME CONTROLS
2.4.1 COARSE ADVANCE CONTROL
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.
2.4.1.1
FINE TRIM ADJUSTER / FTA (where applicable)
Works exactly the same as the knife carriage feed control
2.4.2 SECTION THICKNESS CONTROL
See above: To select section thickness, set the thickness control (1) 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
(see section 2.5).
2.4.3 ADVANCE / REWIND CONTROL
The knob located on the top of the microtome should be used to
reset the feed mechanism before starting a new specimen or
whenever appropriate. The advance / rewind control can also be
used for fine advance of the specimen
The feed used indicator on the front cover of the
microtome shows how much forward travel is
available. When the white pointer has moved into
the red section, the feed mechanism has reached its limit and should be
rewound.
Warning:
The mechanism must not be rewound with the microtome arm at the top of its stroke.
Either rotate the cutting handle to move the arm down or set the section thickness to 0µm to
disengage the ratchet mechanism.
