Rotor Sheave

1.  Sheave
2.  Set Screw
3.  Shaft key

4.  Sheave Bolts
5.  Sheave Hub
6.  Threaded Puller Holes

2. 

Remove the set screw from the sheave (2).

3. 

Remove the sheave bolts (4) and thread them into the puller 
holes on the sheave hub (6).

4. 

Turn in the bolts evenly in 1/4-turn increments to pull the 
hub and the sheave slightly apart so they can move on the 
shaft. 

5. 

Lightly tap the sheave hub with a block of wood to move it 
in or out on the shaft so it is re-aligned with engine clutch 
sheave. Confirm with the straight edge along the face of the 
engine clutch and rotor sheave.

6. 

Once aligned, insert the hub bolts and snug them up to the 
sheave. Recheck alignment.

7. 

Tighten hub bolts evenly in 1/4-turn increments until firmly 
seated. Install and tighten the set screw.

8. 

Re-check the alignment again with the straight edge once 
the bolts are tight. Re-check belt tension.

9. 

Reinstall the guard.

7.7  Rotor Blades

Observe rotor blade sharpness at each use. Sharpen every 
50 hours of operation. 

The rotor and ledger knives need to be sharp for the best 
performance. Periodic inspection is recommended. Keep the 
blades sharp to reduce the amount of power required during 
operation. 

Check blade sharpness more often if processing material with 
a lot of sand, soil or dirt in it. 

If the chipper is not pulling the 

material or material must be pushed into the chipper, the 
edges of the rotor blades have rounded over and are probably 
dull.

Reverse or sharpen the blades if the cutting edges become 
dull. When replacing, reversing or sharpening, always do both 
blades.

Rotor Blades, Changing

 CAUTION!

Risk of getting hands pinched or wedged 

between lower rotor housing and rotor. Turn 

rotor slowly and be aware of hand positioning.

W032

Procedure

1. 

Open the upper rotor housing. Turn the rotor around by 
hand as required to access the blades.

2. 

Check whether the blades can simply be rotated (turned) or 
need to be removed to be sharpened or replaced.

IMPORTANT!  Rotor blades can be sharpened on both sides 
as long as the correct clearance between them and the 
ledger knife is maintained. 

3. 

To sharpen, remove both blades from the rotor.  

4. 

Sharpen each at a 45° angle to provide the best cutting 
effect.
