Assemble the cutterblade with the turned up edges facing towards the
engine. S ecure the cutterblade using the bolt (1 ), spring washer (2), and
distance piece (3 ) and tighten to a torque of 5 4 Nm
A slightly worn cutterblade may be re-sharpened. B oth blade edges
must be sharpened equally to ensure balance. S harpen the cutterblade
every 25 mowing hours or more frequently if conditions require.
Remove the cutterblade from the mower and clean using a brush and
water. Inspect the cutterblade for signs of damage.
S harpen both cutting edges with a flat file to restore performance.
Ensure that the cutterblade is balanced. Use a screw driver with a
round shaft to support the cutterblade through its centre hole. Hold the
cutterblade horizontal and then release. A balanced cutterblade will
remain horizontal.
If the cutterblade is not balanced the heavy end will rotate downwards.
S harpen the heavy end until the cutterblade is correctly balanced.
