15.5 Sharpening the mowing blade

VIKING recommends replacing a blunt
blade with a new one. Resharpening a
blunt mowing blade should only be carried
out by a VIKING specialist dealer as he
has the necessary expertise and special
tools.
Correct operation of the machine
can only be ensured with a very
precisely balanced mowing blade.
An incorrectly sharpened blade
(e.g. imbalance, incorrect
sharpening angle) increases noise
emissions and can result in
damage to the machine.
