MAINTENANCE & SERVICE
Knives
The performance of the chipper will depend largely on the condition of the knives. If the knives are
dull or damaged you will create a lot of unnecessary stress on the whole machine. The knives are
reversible and can easily be reversed or replaced by removing the two 3/8 bolts. (Figure 7) We
recommend that the knives be resharpened by a precision sharpening service to retain the proper
angle. The angle of the cutting edge should be 45 degrees. It is good to keep an extra set of knives
on hand to use while the other set is being sharpened.
Anvil
The depth of your anvil will also affect the performance of your chipper. The anvil is also reversible.
Follow these steps to adjust the anvil. (Figure 8)
• Loosen the two 1/2” bolts that clamp the anvil in position.
• Open the top of the rotor housing so you can watch the distance between the knives and anvil.
• Move the anvil to within 1/32” (.08mm) of the closest knife using the 3/8” adjustment rods. The
knife depth may vary a little as you turn the rotor. This is normal.
• Retighten the bolts to secure the anvil.
