Operation
Fine adjustment of the force balance
If another accessory of a different weight is
mounted on the object head (
33
), you must
check whether it is necessary to readjust the
force balance.
Checking the correct setting:
•
Attach the new accessory and clamp the
specimen.
•
Set the object head to half the height of the
vertical travel range by turning the hand-
wheel (Fig. 21).
If the object head remains in this exact position,
the setting is correct.
If the object head moves, i.e. it is raised or low-
ered, fine adjustment is necessary.
Failure to adjust the force balance
may result in injury while working.
The force balance is adjusted using the screw
(
34
), which can be accessed by removing the
section waste tray on the bottom of the base
plate of the microtome. Use the Allen key pro-
vided, size 5 (with handle!) for the adjustment.
•
If the object head moves
downwards
, turn the
screw approx.
1
/
2
turn
clockwise
.
•
If the object head moves
upwards
, turn the
screw (
34
) approx.
1
/
2
turn
counterclockwise
.
•
Continue this procedure until the object
head no longer moves once released.
