mount the writing utensil holder to the housing (pos. 1).
5.4.3 Balance scale bar (pos. 24)
5.4.3.1 Installation of the balance scale bar
Guide the balance scale bar with mounted counterweight (pos. 43) through the opening on
the left side of the housing underneath the mounted release lever (pos. 32). Ensure that the
mounted counterweight of the balance scale bar is on the same side as the release lever.
Carefully place the cutting bolt (pos. 25) into the two cutter holders (pos. 26) in the
housing.
Handle the cutters of the balance scale bars gently and with great care. Ensure that the
tips in particular are not exposed to shocks or dropped into the cutter holders to avoid
damage to the cutting geometry. Damaged cutter holders result in inaccurate test results.
Caution: risk of cutting!
The cutters at the balance scale bar have very sharp edges that can cause severe cuts.
Always wear protective gloves to install and/or transport the balance scale bar.
5.4.3.2 The balance scale bar
The VKA-110 comes with adjusted balance scale bar. The adjustment is a life-long
adjustment.
