13.8 Sharpening the mowing blade

Risk of injury!
Check the blade for damage before
installing. The blade must be
replaced if notches or cracks are
identified, if the cutting edges have
been sharpened back by more than
15 mm, or if the blade is thinner
than 2 mm at any point (
VIKING recommends having the mowing
blade sharpened by a technician.
Operation of the machine is impaired in the
case of an incorrectly sharpened blade
(incorrect sharpening angle, imbalance
etc.).
Sharpening instructions:
● Remove the mowing blade (
● Cool the mowing blade when
sharpening, e.g. with water. The blade
must not be allowed to display blue
colouring, as this would reduce its
cutting quality.
● Sharpen the blade evenly to prevent
vibrations due to imbalance.
● Observe a sharpening angle of 30°.
● After sharpening, remove any
sharpening burr at the cutting edge
using fine sandpaper if necessary.
