5. Turn flywheel to blade change position (pic 2)
6. Insert locking timber (pic 2)
7. Clean all debris from around the blade bolt and nut with a metal pick
8. With a 24mm socket undo the two blade bolt nuts and remove both bolts/nuts
and washers steadying the blade with the other hand making sure it doesn’t
fall
– WARNING these blades are sharp, rigger gloves must be worn
9. Carefully remove the blade from the flywheel
10. Clean blade seat on the flywheel thoroughly before fitting new or resharpened
blades WARNING
– the blades must not have any debris underneath them
when tightened, the smallest amount of debris behind the blade could result in
the blade coming loose causing damage to the machine
11. Re-fit blades, with new bolts, washers and nuts in the order shown in (pic 3)
12. Shims may be required to keep the gap between the blade and the anvil on
the inner edge (closest to the flywheel shaft) at 1mm
– see page 28, Figure 15
13. A calibrated torque wrench must be used to tighten the blade bolts to a torque
setting of 310NM
14. Remove locking timber, rotate flywheel to next blade position and repeat 6-13
15. Close chipping chamber lid and re-fit bolts tightening to 86NM
16. Re-fit battery leads
WARNING
– Failure to keep blades sharp will overload the engine and bearings
which could result in machine breakdown.
Blades must not be used beyond the wear mark (pic 4) failure to comply with this
could result in damaging the machine, injury or loss of life
Blade sharpening
For optimum performance, blades need to be kept sharp. Minimum safe blade size
after sharpening is shown in Figure 18. After sharpening, the blade gap must be
reset by using a blade shim as shown in Figure 19. Shims are available in
thicknesses of 0.5, 1, 1.5, 2 & 2.5mm as part number 12-03-093. On no occasion
must more than one shim be fitted under each blade at any time. A gap of 1mm
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 1mm at
