5.7 Blade Sharpening
For optimum performance, blades need to be kept sharp. Minimum safe blade size
after sharpening is shown below. Also markon the blade. After sharpening, the blade
gap must be re-set by using a blade shim. Shims are available in thicknesses of 0.5,
1, 1.5, 2 & 2.5mm as part numbers 14-03-042-05, -10, -15, -20 and -25. On no
occasion must more than one shim be fitted under each blade at any time. A gap of
3mm must be set from the inner blade tip to anvil after sharpening by placing an
appropriate shim under the blade (also see flywheel assembly). The outer blade tip
is automatically set due to the anvil being set at an angle to the blade. With 3mm at
the inner blade tip, the outer blade tip should be 5mm from the anvil as shown below.
Blades must not be used beyond the wear mark. Failure to comply with this could
result in damaging the machine, injury or loss of life.
The complete blade fastener set must be replaced every time blades are
changed and torqued up to 310 Nm
DO NOT Lubricate the Bolts when fitting.
