CUTTERBLADE Continued.
How to sharpen and balance the cutterblade: A slightly
worn cutterblade may be re-sharpened. All cutting edges
must be sharpened equally to ensure balance. Sharpen the
cutterblade every 25 mowing hours or more frequently if
conditions require. Remove the cutterblade from the mower
30 -45
and clean using a brush and water. Inspect the cutterblade for
signs of damage.

WARNING - PREVENT ACCIDENTS: DO NOT use a
damaged or excessively worn cutterblade.
Sharpen both cutting edges with a flat file to restore the orig-
inal cutting edges.

Ensure that the cutterblade is balanced. Use a screw driver
with a round shaft to support the cutterblade through its cen-
tre hole. Hold the cutterblade horizontal and then release. A
balanced cutterblade will remain horizontal. If the cut-
terblade is not balanced the heavy end will rotate down-
wards. Sharpen the heavy end until the cutterblade is cor-

rectly balanced.
