the outside closest to the edge of the
cutting rotor (refer to diagram for more
detail).
After the correct clearance is set, fully
tighten the clamping bolts using a torque
wrench to 35 Nm and tighten the locking
nuts on the adjustment bolts.
Note: Before adjusting the knives, ensure
the gap between the holding block and the
anvil is 4 - 5 mm. If not, then the anvil can
be adjusted through the mounting slots.
Once the position has been set, tighten the
three M10 countersunk anvil bolts and
torque to 50 Nm, then make further
adjustments with the knives as described
above.
Turn the cutting rotor slowly by hand to
check that it turns freely.
Close and secure the outlet chute.
Anvil adjustment/replacement
When cutting edge of the anvil is dull, the anvil may be reversed can be reversed. Each edge of the anvil will typically last for several
hundred hours of operation. When both edges are worn, the anvil will need to be replaced.
To access the anvil the inlet chute needs to be removed (use the reverse procedure to fit the inlet on page 3). A 6 mm Allen key,
17 mm socket and an extension are required to remove the anvil.
With the knives removed or set right back, the gap between the knife holding block and anvil should be 4 - 5 mm. The position of
the anvil can be adjusted through the mounting slots. When this has been set, tighten the three M10 countersunk anvil bolts using
a torque wrench to 50 Nm and then make further adjustments with the knives as described above.
Turn the cutting rotor slowly by hand to check that it turns freely.
Engine servicing
For servicing of the engine, please refer to the Honda engine manual.
Engine oil
It is recommended you check the oil level every time you use your chipper. To check the oil level,
unscrew the oil filler cap/dipstick, clean the dipstick, then insert the dipstick without screwing it
into the thread. Fill as necessary, using the diagram as a reference. For optimal performance of
your chipper, the engine oil should be completely changed every 100 operating hours, or roughly
once every 12 months on average.
WARNING! Every time the knife clamping bolts are torqued up to 35 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 (m8x35 bolts of grade 10.9 or higher). Use only genuine Hansa bolts.
