1. This clearance should be checked on a weekly basis or as knives are changed. To check the anvil
clearance, follow all pre-maintenance shut down procedures. Once all safety procedures are completed
the anvil to knife clearance can be checked.
2. In order to check the clearance one person will need to climb into the infeed hopper. Use a feeler gauge
or the anvil to knife gauge supplied by Bandit to check the clearance of the rst knife to the anvil. Check
the clearance at the left and right sides of the knife.
3. Once that knife has been checked climb back out of the infeed hopper, remove the drum lock pin, and
very carefully rotate the chipper drum so the other knives can be checked.
4. Once all knives have been checked adjust the anvil according to the closest knife. The anvil to knife
clearance should be .120 inches (3.0 mm).
5. Set the closest knife to this distance.
1. To adjust the anvil rst loosen two of the hex nuts on either the inside or outside of the anvil puller block.
If the anvil needs to be adjusted closer to the drum, loosen the outside anvil adjuster hex nuts. If the
anvil needs to be adjusted away from the drum, loosen the inside anvil adjuster hex nuts.
2. Loosen the anvil bolts from underneath the machine.
3. Once the components have been loosened, move the anvil to the correct clearance using the anvil
adjuster bolts and hex nuts.
4. Once the knife is set to the correct clearance, .120 inches (3.0 mm), retighten all components.
5. Make sure bolts are torqued to their specic bolt torques refer to bolt torques on page 44.
6. Carefully rotate the chipper drum to make sure all the knives clear the anvil.
