● After sharpening, remove any
sharpening burr at the cutting edge
using fine sandpaper.

12.9 Wear limits of the blades

The blades must be reversed or
replaced before reaching the
specified wear limits (A, B, C, D).
VIKING recommends VIKING
specialist dealers.
The specified values should be
measured at several points (two or
three recommended) along the
cutting edge on all the blades.
Use the smallest value for a blade.
We recommend that you always
reverse or replace all the blades at
the same time.

bore on the blade.
Minimum distance (B) on the blades (2):
B = 6 mm
The particular blade (2) must be
reversed or replaced if one of the
two distances measured is less
than the minimum distance (B).
