Adjust the vice angle to suit the specfication of the
chain to be sharpened. One set of teeth can be
sharpened with the vice angle set at the correct
setting then the vice rotated to the same angle on
the other scale.
The lever on top of the vice angle adjuster is used
to adjust the chain clamp - adjust to clamp the
chain when the grinding disk is lowered - do not
overtighten.
Once the chain clamp lever is adjusted it will not
need moving unless a different width of chain is
used. The clamping of same width chains will be
done automatically by the hydraulic action each
time the grinding disc is brought down.
