Remove the knives for sharpening 

 

Open the rotor housing cover by removing the two outlet chute locking bolts with a 13 mm spanner, then lift the 
rotor housing cover to access the cutting rotor. Rotate the cutting rotor to gain access to the knives, then engage 
the belt drive to stop the cutting rotor from rotating. 

 

 

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 

 

Be careful not to drop the nuts, bolts, washers or knives into the 
chipper 

 

A stick magnet can be used to retrieve them if this does occur  

 

 

Measure the width of the knife and check that it will be at least 35 mm 
after sharpening. If the knives will be shorter than 35 mm, then the knives 
should be replaced. Please contact your nearest Hansa dealer. 

Sharpen the knives 

 

 

Sharpen the knives on a surface grinder. A cutting angle of 40 ° is critical 
for the performance of the chipper. Make sure plenty of coolant is used 
when grinding to avoid softening of the steel knives. 

Reinstall the knives 

 

Clean  all  mounting  surfaces  and  remount  the  knives  in  the  reverse  procedure.  Tighten  the  nuts  using  a  torque 
wrench to 22 Nm.
