Adjust the anvil at this stage as the
location of knife edge will change after
sharpening or replacement.
The anvil is reversible. Normally the edge
will last for over 200 operating hours.
When the edge is dull, it can be reversed.
When both edges are worn, the anvil
should be replaced (contact Hansa for a
replacement).
The clearance between the knife and
anvil should be approx. 1 mm on the
inside closest to the bearing and 3 mm on
the outside closest to the edge of the
rotor (refer to diagram for more detail).
Ensure you are using the outer blade for
calibrating these distances.
The gap between the knives and the anvil
is tapered out slightly to allow for a small
amount of movement in the rotor as it
bites into the wood.
The anvil position can be adjusted by
loosening the anvil mounting bolts. Once
adjusted correctly, tighten the anvil
mounting nuts using a torque wrench to
22 Nm.
If there is not enough clearance, the knife
edge may touch the anvil through
deflection when cutting heavy branches
and damage the sharp edge. Too much
clearance will allow small twigs and
fibrous materials to be dragged through
without being cut.
Turn the cutting rotor by hand to check
that it turns freely.
Reassemble the housing and inlet chute
by repeating steps 1-3 in reverse.
Note: When reassembling the housing,
first align the hooks on the curved wall
with the tabs near the outlet on the
housing front. Once these are aligned
use a nylon hammer (or other suitable
alternative) to hammer the back of the
housing to locate the remaining four
tabs. Do not attempt to do up the
housing bolts until these tabs have been
aligned.
