Regularly check that the cutterblade securing bolts

(items 1 and 2) are tightened to the specied 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.
