bolts will cause the anvil mounting plate to slide
further along the slotted holes. Ensure you
tighten the two bolts evenly to avoid setting the
anvil on an angle.
Once the correct anvil position has been set,
ensure the locking nuts on the adjustment bolts
are tightened. Additionally, ensure the
clamping nuts are torqued to 77 Nm.
Remove the rotor pin and turn the rotor slowly
by hand to check that it turns freely.
Close and secure the rotor cover.
Anvil adjustment
Whenever the chipper knives are inspected/sharpened, the condition of the anvil should also be checked. If the edge of the anvil
is significantly rounded and/or uneven, then it should be reversed or replaced. Typically, the anvil will maintain its sharp edge for
about 500 hours of operation.
Anvil replacement
Lift the swing arm up and lock with rotor pin. Refer to instructions for “Lifting the swing arm for access” in the
“Maintenance & Service” section in this manual.
To remove the anvil, you must remove the four
countersink clamping bolts using an 18 mm
socket and extension. If the bolt head turns, hold
it with a 6 mm Allen key.
Note
:
Do NOT
use the Allen key to turn the bolt;
turn only the nut.
Inspect the condition of the Anvil.
If the other side of the anvil hasn’t been used yet: rotate the anvil 180 degrees
and place it back on the feed roller housing wall. If both sides of the anvil are blunt: remove the anvil and replace
it with a new one. Contact Hansa if a replacement anvil is required.
Tighten the clamping bolts, ensuring there is a spring washer between the clamping plate and each nut. Torque
the nuts to 77 Nm. Check the gap between anvil and knives as per knife sharpening & setting procedure.
WARNING!
Every time the knife clamping bolts are torqued up to 190 Nm and loosened off again, the life of the bolts is
reduced. The knife clamping bolts must be replaced at most after every six sharpens. Contact Hansa for replacement
bolts (M16x50 countersunk bolts of grade 12.9 and Zinc finish). It is recommended to use only genuine Hansa bolts.
