How to re-sharpen the knives:
If you don’t have a surface grinder or are unsure how to re
-sharpen the knives, contact a professional saw doctor or Hansa to
arrange re-sharpening.
Tools and materials required for re-sharpening (approx. 40 mins):
•
2 x 13 mm spanners
•
2 x 16 mm spanners
•
6 mm hexagonal Allen key
•
Nylon hammer (recommended)
•
Surface grinder

Coolant
Remove the knife for sharpening
Remove the inlet chute - use two 13 mm spanners to
remove the nuts and bolts holding the inlet chute on.
Open the cutting rotor housing by removing the four
housing bolts using two 16 mm spanners.
Using a nylon hammer (or suitable alternative), gently
dislodge the housing from its grooves and remove it.
Use a 13 mm spanner to remove the knives from the
rotor. There are three nuts you must remove to do so.
If the bolt head turns, hold it with a 6 mm
hexagonal Allen key
Note
:
Do NOT
try to loosen the bolt with the hexagonal
Allen key.
WARNING!

operate your chipper with blunt knives.

Blunt knives result in damage to the chipper
WARNING!

the cutting means can still move.
