Regularly check that the cutterblade securing bolts
(items 1 and 2) are tightened to the specified torque
and re-new cutterblade - lockplate.
Bolt (item 1) - Torque to 70-95Nm (52-70 Ibf.ft).
Bolt (item 2) - Torque to 40-55Nm (30-40 Ibf.ft).
Ensure that each cutterblade is balanced. Use a
screw driver with a round shaft to support the cut-
terblade through its centre hole. Hold the cutter-
blade horizontal and then release. A balanced cut-
terblade will remain horizontal. If the cutterblade is
not balanced the heavy end will rotate downwards.
Regrind the heavy end until the cutterblade is cor-
rectly balanced.
