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 flat edge for
about 500 hours of operation.
Avnil replacement
Remove the feed roller guard by unhooking the
four rubber latches. Unhook the springs from the
base of the chassis. Lift the swing arm up and
insert the rotor pin (located underneath the
control panel) into the tab on the housing to lock
the swing arm in place.
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.
Note
: Ensure the gap between the knives the
edge of the anvil is 3 mm. If not, then the anvil can
be adjusted via the two adjustment bolts
between the clamping bolts.
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 back up using an 18 mm socket, ensuring there is a spring washer between the
clamping plate and each nut. Torque the nuts to 44 Nm.
Belt tension
Correct belt tension is crucial for minimising belt wear and maximising machine efficiency. To check the belt tension, fully engage
the belt then open the bonnet. There should be approximately 5 mm deflection in the belt when pressing firmly on the belt (as per
the image below). Alternatively, the tension can also be checked by looking at the tensioning device from underneath the machine;
the notch on the
idler arm should line up with ‘15°’ on the tensioner
. If required, adjust belt tension.
Note
: After using the machine for the first time, or after replacing the belts, it is recommended to check the tension again after the
first 5 hours of operation, as the belt will stretch as it wears into the system.
